DCI OpenShift Agent
dci-openshift-agent
provides Red Hat OpenShift Container Platform (RHOCP) in
Red Hat Distributed CI service.
There are some benefits of running the DCI OCP Agent:
- Automation of nightly/dev preview/candidate/ga OCP component testing
- CI runs on your own hardware
- Red Hat doesn't have access to your hardware, the agent reports metrics/logs back to distributed-ci.io
- The agent leverages the OpenShift IPI/UPI/AI/ACM/ZTP installers
- You have access to all your jobs logs and metrics through distributed-ci.io where you can also set notifications for errors/exceptions
See the installer's documentation for details about the supported/required variables for each deployment method.
Requirements
Network requirements
This is a summary taken from the upstream Network requirements guide from OpenShift:
- Each server needs 2 NICs pre-configured. NIC1 for the private/provisioning network and NIC2 for the baremetal network. NIC interface names must be identical across all nodes
- Each server's NIC1 (provisioning) must be configured for PXE booting in BIOS/UEFI
- Each server must have IPMI configured and functional
- Each server must have static IP addresses for their baremetal NICs plus a dynamic pool of 5 or more IP addresses with a short TTL (2h) for the bootstrap VM
- Must have 2 reserved virtual IPs for API (
api.<cluster>.<domain>
) and wildcard ingress (*.apps.<cluster>.<domain>
) and DNS setup for both. Please follow the Openshift Baremetal DNS server configuration as a reference guide - Optional - Include DNS entries for the hostnames for each of the servers
- Nightly builds require that the provisionhost (SNO or IPI installs) is able to communicate directly to the controller server.
Systems requirements
DCI OpenShift Agent
needs a dedicated system to act as a controller node
.
It is identified as the DCI Jumpbox
in this document. This system will be
added to a standard OCP topology by being connected to the OCP baremetal
network
. The DCI OpenShift Agent
will drive the RHOCP installation workflow
from there.
Therefore, the simplest working setup must be composed of at least 5 systems (1 system for DCI and 4 systems to match OCP minimum requirements).
Please use the OpenShift Baremetal Deploy Guide (a.k.a.
openshift-kni
) as a
reference for how to properly configure the OCP networks, systems and DNS.
Choose the OCP version you want to install and follow these steps to configure the networks and install RHEL 8 on the OpenShift Provisioning node.
As mentioned before, the DCI Jumpbox is NOT part of the RHOCP cluster. It
is only dedicated to download RHOCP
artifacts from DCI
public
infrastructure and to schedule the RHOCP cluster deployment across all systems
under test (1x OpenShift Provisioning node and several OCP nodes).
The OpenShift Provisioning node is used by the OpenShift installer to provision the OpenShift cluster nodes.
The 3 remaining systems will run the freshly installed OCP Cluster. “3” is the minimum required number of nodes to run RHOCP but it can be more if you need to.
Jumpbox requirements
The Jumpbox
can be a physical server or a virtual machine.
In any case, it must:
- Be running the latest stable RHEL release (8.4 or higher) and registered via RHSM.
- Have at least 160GB of free space available in
/var
- Having full access to Internet is highly recommended
- Be able to connect the following Web urls:
- DCI API: https://api.distributed-ci.io
- DCI Packages: https://packages.distributed-ci.io
- DCI Repository: https://repo.distributed-ci.io
- EPEL: https://dl.fedoraproject.org/pub/epel/
- Ansible Runner Repository: https://releases.ansible.com/ansible-runner/
- QUAY: https://quay.io
- Nightly releases: https://registry.ci.openshift.org
- RED HAT REGISTRY: https://registry.redhat.io
- RED HAT SSO: https://access.redhat.com
- RED HAT CATALOG: https://catalog.redhat.com
- OpenShift Mirrors: https://rhcos.mirror.openshift.com and https://mirror.openshift.com
- GitHub: https://github.com
- Software Factory (gerrit): https://softwarefactory-project.io
- Access to cloudfront CDN
- Have a static internal (network lab) IP
- Be able to reach all systems under test (SUT) using (mandatory, but not
limited to):
- SSH
- IPMI
- Serial-Over-LAN or other remote consoles (details & software to be provided by the partner)
- Be reachable by the Systems Under Test by using:
- DHCP
- PXE
- HTTP/HTTPS
NOTES: - Make sure rhel-8-for-x86_64-appstream-rpms repo provides access to libvirt => 6.0.0 packages - The installer may require access to other endpoint (CDNs). The list above is for well know URLs that be subject to change.
Systems under test
Systems under test
will be installed through DCI workflow with each job
and form the new “fresh” RHOCP cluster.
All files on these systems are NOT persistent between each
dci-openshift-agent
job as the RHOCP cluster is reinstalled at each time.
Therefore, every expected customization and tests have to be automated from the
DCI Jumpbox (by using hooks) and will therefore be applied after each
deployment (More info at Jumpbox Configuration).
Optional DCI Access
- We strongly advise the partners to provide the Red Hat DCI team with access to their jumpbox. This way, Red Hat engineers can help with initial setup and troubleshooting.
- We suggest to run the
full virtualized
provided example first to understand how thedci-openshift-agent
works before going to production with a real lab.
Setting up access to DCI
The DCI dashboard gives you a view into what jobs you have run in your distributed agent. In order to gain access to it you have to:
- Go to https://www.distributed-ci.io/ and click login. You will be redirected to sso.redhat.com so you'll use your RH account credentials
- If you are not part of any teams you can contact an admin to get yourself added
- You will have to create a Remote CI for use later, go on the left navigation bar on the
Remotecis
option and click on "Create a new remoteci" - Fill out the description and which team it belongs to then click Create
- You should see your newly created remoteci in the list, you can get
the credentials in YAML format by click the button in the
Authentication column. This should be saved under
~/.config/dci-pipeline/dci_credentials.yml
.
Installation of DCI Jumpbox
Before proceeding you should have set up your networks and systems according to the baremetal-deploy doc that was referenced above.
Provision the Jumphost with RHEL8. This includes subscribing the host to RHSM and ensuring it's receiving updates.
The dci-openshift-agent
is packaged and available as a RPM file.
However,dci-release
and epel-release
along with additional support
repos must be installed first:
For RHEL-8
subscription-manager repos --enable=rhel-8-for-x86_64-baseos-rpms
subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms
subscription-manager repos --enable=ansible-2-for-rhel-8-x86_64-rpms
For CentOS Stream 8
dnf install centos-release-ansible-29.noarch
For Both
dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf -y install https://packages.distributed-ci.io/dci-release.el8.noarch.rpm
dnf config-manager --add-repo=https://releases.ansible.com/ansible-runner/ansible-runner.el8.repo
dnf -y install dci-openshift-agent
Folders and files location
Once dci-openshift-agent
package is installed, the files and resources you can find in this repository will be placed in the following locations:
/etc/dci-openshift-agent
contains these folders and files:dcirc.sh.dist
file,hooks
folder,settings.yml
file./usr/share/dci-openshift-agent/
gathers the following folders and files:action_plugins
folder,ansible.cfg
file,dci-openshift-agent.yml
file,group_vars
folder,plays
folder,test-runner
script andutils
folder./var/lib/dci-openshift-agent
folder holds thesamples
folder.
Also, have in mind that:
dci-openshift-agent
user (with sudo permissions) and group are created
Installation of OCP Provision Host
The provision host is part of the OCP requirements, as such you should follow the guide linked before. The main things you need to know about the provision host are:
- Provision with RHEL8
- Subscribe to RHSM and make sure it is receiving updates
- Install the EPEL RPM package
- Must have 2 NICs: one for the baremetal public/routed network and another for the provisioning private network
- Create a
kni
user - Create a ssh key for the
kni
user
Copying the ssh key to your provisioner
# su - dci-openshift-agent
% ssh-keygen
% ssh-copy-id kni@provisionhost
Collections
The dci-openshift-agent
relies on redhatci.ocp ansible collections that provide a set of roles and plugins that bring the functionality to the agent. The ansible collections are installed as a dependency of the agent and the project is hosted in https://github.com/redhatci/ansible-collection-redhatci-ocp

Disconnected mode in DCI OCP agent
When using the agent in a disconnected environment, special variables should be used. See the disconnected doc for more details.
Pull secrets
Pull secrets are credentials used against container registries that require authentication.
DCI provide pull secrets used to deploy OCP on every job.
cloud.openshift.com
- Insights monitoringquay.io
- Openshift releasesregistry.ci.openshift.org
- Nightly buildsregistry.connect.redhat.com
- Red Hat imagesregistry.redhat.io
- Red Hat images
These pull secrets are used by default, but the agent allows using other pull secrets if needed through some variables.
openshift_secret
: String with secrets that are appended to the job's provided pull secrets. Used to include additional credentials. This is an agent variable.disconnected_registry_auths_file
: A file with a string that contains the auths for private registries.pullsecret_file
: File with secrets in JSON format that will be used along with the ones provided by DCI job and theopenshift_secret
.
The content all these variables is merged by DCI, those secrets are combined in a single podman authentication file used to interact with the required registries during the mirroring, image inspections, pruning tasks performed byt the DCI Openshift agent.
Important:
- Secrets are processed in the following order: Job secrets --> openshift_secret --> disconnected_auths --> pull_secret_file
- If a registry entry exists in multiple sources, the last one processed takes priority
- It is recommended that the additional secrets are set in the form of registryA/
to use an specific auth entry against a registry as recommended in the podman documentation
Disconnected environment
Another related variable is disconnected_registry_auths_files
used in IPI or SNO installs.
This is an inventory variable used in disconnected environments. The content of this file is appended to the list of DCI provided pull secrets. This file is used for two main purposes.
- To allow the cluster to communicate to a local registry
- To use to mirror images to the local registry
Storing secrets
You can store secrets in an encrypted manner in your pipelines and YAML inventories by using dci-vault
to
generate your encrypted secrets. Details in the python-dciclient documentation.
Deploying operators
The Agent manages the mirroring and deployment of most of the day-2 operators. For others, it can configure them by setting up the corresponding operands.
The workflow for the deployment is:
-
Operator mirroring for disconnected environments
-
Operator installation
-
Operator configuration
Operators mirroring for disconnected environments
The opm_mirror_list variable, controls the operators that are mirrored when dci_disconnected is true. The Agent takes care of mirroring the required operator's images and creates a pruned catalog source for the OCP cluster. Some examples are below:
- Explicit definition (This is recommended)
Example 1:
Definition of three operators. Two operators specify the channels, while the last compliance-operator includes all the channels.
opm_mirror_list:
file-integrity-operator:
channel: stable
cluster-logging:
channel: stable-5.8
compliance-operator:
Example 2:
Same three operators, this time all the channels are included.
opm_mirror_list:
file-integrity-operator:
cluster-logging:
compliance-operator:
- Implicit definition, always includes all the channels (Prefer to use Example 2 above)
Example 3:
A pruned catalog with all operator's channels.
opm_mirror_list:
- compliance-operator
- file-integrity-operator
- cluster-logging
NOTE: By default the catalog source name that can be used to create operator subscription is named mirrored-redhat-operators, can be changed with
dci_catalog_source_name
.NOTE: Some operators may have other operators dependencies, for such cases the dependencies must be added to the list.
Operators installation
Operator subscriptions and installation monitoring are controlled by the dci_operators
variable, which allows basic or custom installations. An example of how to define the dci_operators
variable is shown below.
dci_operators:
- name: compliance-operator
catalog_source: mirrored-redhat-operators
namespace: openshift-compliance
- name: cluster-logging
catalog_source: mirrored-redhat-operators
namespace: openshift-logging
- name: local-storage-operator
catalog_source: mirrored-redhat-operators
namespace: openshift-local-storage
channel: stable
starting_csv: 4.14.0-202307190803
operator_group_name: local-storage
skippable: true
operator_group_spec:
targetNamespaces:
- openshift-local-storage
- name: ocs-operator
catalog_source: mirrored-redhat-operators
namespace: openshift-storage
operator_group_spec:
targetNamespaces:
- openshift-storage
ns_labels:
openshift.io/cluster-monitoring: "true"
Important: For a successful operator installation, ensure that the settings defined in dci_operators align with the packages available in the specified catalog_source. The following examples highlight potential misconfigurations that can cause the operator installation to fail:
- Selecting an installation channel that is unavailable.
- Configuring an operator group with settings not supported by the operator.
- Specifying a starting CSV that is not available in the selected channel.
Operator configuration
For some operators, the agent support the operand creation by setting to true
specific flags. See enable_<operator>
variables above. Also, the operator configuration can be executed as part of a run during the /hooks/install.yml
phase.
Install all operators from a catalog
All the operators available in a catalog can be installed on the cluster by setting install_all_from_catalog
. This is mainly to test if the operators are deployable by OLM. There is no additional testing, or configuration executed after a running CSV is detected.
The catalog source namespace defaults to openshift-marketplace
but that can be set using the install_all_from_catalog_source
variable in case the catalog was created on a different namespace.
install_all_from_catalog: <my-ocp-catalog>
install_all_from_catalog_source: <my-ocp-catalog-namespace>
Additional Catalogs
Additional catalogs can be configured for the cluster to provide another source to install operators. Set the custom_catalogs
variable with the references to the catalog images. For example:
custom_catalogs:
- quay.io/telcoci/sriov-operator-catalog:latest
- quay.io/telcoci/simple-demo-operator:v0.0.3
- quay.io/telcoci/nfv-example-cnf-catalog:v0.2.9
- icr.io/cpopen/ibm-operator-catalog:latest
All the images available in the defined catalogs will be mirrored when dci_disconnected
is true
and a local_image_registry
is defined.
Please see the settings table for the variables names to control the Operators deployment.
Mirroring from directory
In fully disconnected environments, mirroring can be performed by loading operators previously stored in a local file. The oc mirror
plugin, allows the creation of catalogs that can be stored on a USB stick that will be used later to load operators on a local image registry.
The dci-openshift-agent can consume files generated by the oc mirror
plugin. The agent uploads these files to the local registry, creates the catalog source, and applies the corresponding ImageContentSourcePolicies (ICSPs). The catalog source is then used to deploy the operators enabled for testing.
The operator_catalog_dir
variable should be set to a valid directory that contains one or multiple archive files generated using the oc mirror plugin. In the provided example, operator_catalog_dir: /data/
is used as the path to the archive tar files.
Subscriptions for the mirrored operators can be defined using the dci_operators
variable as explained above.
Minio deployment
Some workloads like Migration Toolkit for Containers or Loki may require an object Object Storage provider. For such cases, a Minio instance can be deployed on the OCP cluster by setting true
to the enable_minio
flag.
In the DCI Openshift Agent integration, an initial bucket named loki
is deployed and is used for the logging if no information about an external Object provider are provided.
The following variables allow customizing the Minio deployment. Please see the minio_setup role for additional details.
Variable | Default | Required | Description |
---|---|---|---|
minio_claim_size | 10Gi | No | Requested storage for Minio |
minio_storage_class | undefined | Yes | A storage Class with Support for RWX volumes |
minio_namespace | minio | No | Deployment Namespace |
minio_access_key_id | minioadmin | No | Minio's Initial Username |
minio_access_key_secret | minioadmin | No | Minio's Initial Password |
monio_bucket_name | minio | No | Initial Bucket name |
The workloads that require Object Storage, can use the http://minio-service.minio:9000
endpoint and the default credentials set in the minio_setup role to start shipping data to Minio.
Logging stack
The enable_logs_stack
variable allows configuring OCP to send log files and metrics produced by the infrastructure and workloads to a logging stack. This stack is integrated by the ClusterLogging, Loki and an Object storage system.
The following variables allow customizing the logs stack deployment. Please see the ocp_logging role for additional details.
Variable | Required | Type | Default | Description |
---|---|---|---|---|
logs_access_key_id | False | String | undefined | Key ID for the Object storage system. |
logs_access_key_secret | False | String | undefined | Key Secret for the Object Storage system. |
logs_bucket | False | String | undefined | Object Storage bucket name. |
logs_endpoint | False | String | undefined | Object Storage endpoint. |
logs_region | False | String | undefined | Object Storage region. |
logs_loki_size | False | String | undefined | Loki Deployment Size. See Sizing for more details. |
logs_storage_class | False | String | undefined | Cluster Storage class for Loki components. |
logs_event_router_image | False | String | registry.redhat.io/openshift-logging/eventrouter-rhel8:v5.2.1-1 | Event Router image. |
logs_settings | False | String | "" | An optional yaml file with the variables listed above. The variables defined there take precedence over the ones defined at role level |
Enabling the openshift cluster-logging
components requires high amounts of storage available for data persistency, please take this in consideration during the sizing of the Object Storage provider.
Network Observability stack
The enable_netobserv
variable allows configuring the Network Observability operator to collect information about OCP network flows and traffic. This stack is integrated by the Network Observability Operator, Loki, an Object storage system and the Flow Collector.
The following variables allow customizing the Network Observability stack deployment. Please see the ocp_netobserv role for additional details.
Variable | Default | Required | Description |
---|---|---|---|
setup_netobserv_stackaction | 'install' | No | Role's default action |
setup_netobserv_stacksampling | 50 | No | Data sampling |
setup_netobserv_stackagent_privileged | true | No | Privileged mode allows collecting data from SRIOV functions |
setup_netobserv_stackagent_memory | 50Mi | No | Memory assigned to the agent |
setup_netobserv_stackagent_cpu | 100m | No | CPU assigned to the agent |
setup_netobserv_stackagent_limits_memory | 800Mi | No | Memory limit for the agent |
setup_netobserv_stackprocessor_memory | 100Mi | No | Memory assigned to the processor |

setup_netobserv_stackaccess_key_secret | minioadmin | No | Secret Key for the object storage backend |
setup_netobserv_stackbucket | network | No | Bucket for the Network Observability |
setup_netobserv_stackendpoint | http://minio-service.minio:9000 | No | Object Storage Endpoint. It must exist and be reachable |
setup_netobserv_stackregion | us-east-1 | No | Object Storage region |
setup_netobserv_stackloki_size | 1x.extra-small | No | Loki Stack size. See: Sizing for details |
setup_netobserv_stackstorage_class | managed-nfs-storage | No | Storage class for the Loki Stack |
The configuration setting can be passed using the dci_netobserv_conf_file
containing the variables listed above.
Enabling the Openshift Network observability Operator
requires high amounts of storage available for data persistency, please take this in consideration during the sizing of the Object Storage provider. By default, the stack is configured to use the internal Minio deployment as backend.
Interacting with your RHOCP Cluster
After you run a DCI job you will be able to interact with the RHOCP cluster using the OC client, the API, or the GUI.
-
Using the OC client
bash export KUBECONFIG=/home/<user>/<clusterconfigs-path>/kubeconfig oc get nodes
A copy of the generated kubeconfig file will be attached to the job files section in DCI.
- Using the GUI/API
Obtain the credentials generated during the installation from /home/<user>
/<clusterconfigs-path>
/ocp_creds.txt in
the jumphost.
Get the the URL of the cluster GUI:
```bash
$ oc whoami --show-console
https://console-openshift-console.apps.<cluster>.<domain>
```
NOTE: The dci-openshift-agent is part of a Continuous integration tool aimed to perform OCP deployments, should not be considered for production workloads. Use the above connection methods if some troubleshooting is required.
Non-GA versions of API
Some of the APIs used by the dci-openshift-agent
are still in the beta or alpha version. See the following table for details regarding its status.

Troubleshooting common issues
Troubleshooting basic configuration
Review the following checklist to make sure you've got all the basic pieces in place:
- Is the DCI repo configured?
- Is the dci-openshift-agent package the latest version?
- Does my credentials file contain my remote CI credentials as per the distributed-ci.io dashboard?
- Does my inventory reflect my cluster's expected
configuration? Check the following variables:
cluster
domain
prov_nic
pub_nic
- IPMI configuration for all nodes in OCP cluster:
ipmi_user
,ipmi_password
,ipmi_address
- MAC addresses for all nodes in OCP cluster
- Does my pipeline file reflect the right topic/component for my needs?
- Is my
dci-openshift-agent
SSH key transferred to the provision host? e.g. can I SSH without a password from Jumpbox -> provisioner?
Troubleshooting network connectivity
First, take another look at the network requirements section and make sure your setup looks similar to the proposed basic diagram. Your particular lab may differ in how things are laid out, but the basic points to look for are:
- Your
provisioning
network should be treated as an exclusive "out of band" network only intended to PXE boot the initial cluster OS - Your
baremetal
network should be capable of routing to:- Your jumpbox
- Your cluster nodes' BMCs (e.g. your management network)
- You should have outbound internet access from your Jumpbox (and OCP cluster unless in disconnected mode)
- Your
baremetal
network should be DHCP enabled and have addresses for all of your cluster nodes plus the bootstrap VM (usually not an issue but make sure there are enough IP addresses to lease) - Your Jumpbox, provisioner, and cluster nodes all should be able to resolve
your API and your wildcard DNS entries e.g.
api.<cluster>.<domain>
and*.apps.<cluster>.<domain>
- The provision host should have 2 bridges setup: one for the
provisioning
network and another for thebaremetal
network, are both setup? Are the functional?
Here are a few things you can check to make sure the above assertions are true:
- Can I query the power status of the cluster nodes from the provisioner and
control-plane nodes via e.g.
ipmitool
? - Can I curl one of the mirror.openshift.com resources from the provisioner and cluster nodes?
- Is the lab's DNS resolvable from all places via e.g.
dig api.<cluster>.<domain>
anddig foo.apps.<cluster>.<domain>
?
Troubleshooting OCP bootstrapping
You can monitor the bootstrap/install process by logging into the provision
host and tailing the file ~/clusterconfigs/.openshift_install.log
.
If you're having issues once the agent gets to the point where
baremetal-install
is called, you can check a few things:
- Check the
~/clusterconfigs/install-config.yaml.bkup
file in your provision host (this is a copy of the install manifest fed tobaremetal-install
) and make sure the manifest looks correct - Is the bootstrap VM coming up? e.g.
sudo virsh list --all
should list a VM named*-bootstrap
about 5-10 minutes after you started the run - Is the bootstrap VM getting IP address from the
baremetal
network? Runvirsh console <bootstrap VM>
and a linux login prompt should be visible, hit<Enter>
and it should show 2 IP addresses: a DHCP one as per your configuration, and a static172.22.0.22
on theprovisioning
network - Is your bootstrap VM up coming up correctly? You can
ssh core@172.22.0.2
and check the status of the pods running on the system bysudo podman ps
. You should see (after a few minutes) some pods namedironic-{api,conductor,inspector}
- Check the logs of the
ironic-*
pods withsudo podman logs <pod>
and look for errors/exceptions - Is your
ironic-conductor
able to interact with the BMCs? Try logging yourself to the pod (sudo podman exec -it ironic-conductor /bin/sh
) and make sure there is connectivity to the BMC e.g.ipmi -I lanplus -H <BMC host> -U <BMC user> -P <BMC password> power status
Troubleshooting OCP install
During the deployment, ironic services are started temporally in the bootstrap VM, to help bootstrapping the master nodes. Then after the master nodes are ready to take the role, bootstrap VM is deleted and ironic services are started in the cluster. At both stages you can interact with ironic to see details of the nodes
If you want to interact with ironic services during the bootstrap, get the baremetal network IP of ironic service from the bootstrap VM
[core@localhost ~]$ sudo ss -ntpl | grep 6385
[core@localhost ~]$ ip a s ens3
Get the bootstrap VM ironic credentials from the terraform variables back in the provision host
[dci@provisionhost ~]$ grep ironic_ clusterconfigs/terraform.baremetal.auto.tfvars.json
"ironic_username": "bootstrap-user",
"ironic_password": "foo",
If you want to interact with ironic services in the cluster, get the IP of ironic service from the metal3 resources
[dci@provisionhost ~]$ export KUBECONFIG=/home/dci/clusterconfigs/auth/kubeconfig
[dci@provisionhost ~]$ oc -n openshift-machine-api get pods # find the metal3 pod
[dci@provisionhost ~]$ oc -n openshift-machine-api describe pod <pod> | egrep ^IP:
IP: 192.168.123.148
[dci@provisionhost ~]$ oc -n openshift-machine-api get secrets metal3-ironic-password \
-o jsonpath='{.data.username}' | base64 -d
ironic-user
[dci@provisionhost ~]$ oc -n openshift-machine-api get secrets metal3-ironic-password \
-o jsonpath='{.data.password}' | base64 -d
bar
Then prepare a clouds.yaml with the following information, and replace the IP addresses and password accordingly
NOTE: Starting with OCP 4.7
metal3-boostrap
service usesauth_type: http_basic
, but in in older versions it usesauth_type: none
so there's no need to set auth section with the credentials
clouds:
metal3-bootstrap:
auth_type: http_basic
auth:
username: bootstrap-user
password: $BOOTSTRAP_PASSWORD
baremetal_endpoint_override: http://IP-Provisioining-bootstrapVM-IP:6385
baremetal_introspection_endpoint_override: http://IP-Provisioining-bootstrapVM-IP:5050
metal3:
auth_type: http_basic
auth:
username: ironic-user
password: $IRONIC_PASSWORD
baremetal_endpoint_override: http://IP-Provisioining-Master-IP:6385
baremetal_introspection_endpoint_override: http://IP-Provisioining-Master-IP:5050
Back in the provisioning host, install podman and start a container, set
OS_CLOUD
with metal3 if you want to use the ironic services on the cluster,
or metal3-bootstrap if you want to use the services on the bootstrap VM (if
still running)
[dci@provisionhost ~]$ sudo dnf install -y podman
[dci@provisionhost ~]$ podman run -ti --rm \
--entrypoint /bin/bash \
-v /home/dci/clouds.yaml:/clouds.yaml:z \
-e OS_CLOUD=metal3
quay.io/metal3-io/ironic-client
Finally from the pod you started, you can run ironic baremetal commands
[root@8ce291ff4f4a /]# baremetal node list

components:
- ocp
outputs:
kubeconfig: "kubeconfig"
success_tag: ocp-upgrade-4.10-ok
Please note the following settings:
prev_stages
: Indicates that this pipeline can only be executed after an OCP install or another OCP upgrade, as those will provide thekubeconfig
used to interact with the cluster during the upgrade.dci_main
: Instructs the agent to execute only the tasks related to a cluster upgrade. Accepted values areinstall
andupgrade
.opm_mirror_list
: During the upgrade the operators already installed will be upgraded, those operators must be listed in this variable to perform the operators mirroring according to the target OCP version.
See: dci-pipeline documentation for more details about the configuration settings.
The agent supports 2 types of upgrades:
- Upgrades to the next support
. - release version according the OCP update graph. - Extended Update Support (EUS) upgrades, if the current cluster version is EUS supported version. See preparing EUS-EUS upgrade.
The upgrade process
Some of the relevant tasks executed during a cluster upgrade are listed below:
- A DCI job is created to track the upgrade process.
- The specific target version is calculated based on the OCP upgrade graph.
- The target OCP release is mirrored to the same images
/ that was used for the cluster deployment. For EUS upgrades, the intermediate release images are also mirrored 1. - The ISO, rootfs, and other artifacts are mirrored to the same
webserver_url
used for the initial cluster deployment 1. - The Image Content Source Policies and OCP signature for the new version are applied 1.
- The "cluster version" is patched for the new target version based on the calculated target version.
- The upgrade is executed and monitored for completion.
- The Red Hat operators catalog for the new OCP version is pruned and mirrored according to the
opm_mirror_list
ordci_operators
variables defined in the pipeline file 1. - The current Red Hat operators catalog is replaced with the new one for the target OCP version.
- Information about installed operators is collected based on the current subscriptions.
- The operator upgrade is executed for operators not listed in the
operator_skip_upgrade
list. - An operator upgrade will be triggered if:
- There is a new CSV version available for the currently installed operator in the current channel.
- There is a new default channel available for the currently installed operator. That will usually imply the availability of a new CSV.
- Operators' upgrade starts and is monitored until it reaches the target CSV.
- Cluster resources, machine config pools, cluster operators, etc. are validated to declare a cluster as successfully upgraded.
- The relevant logs and cluster information are uploaded to the "Files" section of the DCI-UI.
1 Only in disconnected environments.
The EUS upgrade
OpenShift offers a way to facilitate the upgrade between two EUS versions. This allows upgrading between even versions, for example from ocp-4.8 to ocp-4.10. Detailed documentation is available in preparing EUS-EUS upgrade
To perform this type of upgrade with DCI, the following conditions must be met:
- Activate the boolean
upgrade_eus
to true. - The cluster has to be installed in an EUS version.
- The topic or target version must be an EUS release.
Transitioning between two OCP releases requires an intermediate version. It's possible to specify the intermediate version through version_inter
, this ignores the upgrade path.
For example, to upgrade to a version where there's no path to it. Specify the intermediate version. version_inter:4.11.5
or to use candidate versions use version_inter:4.11.0-*
.
Note the -*
, this will help to include candidate versions in the search.
Upgrade notes:
-
The upgrade process is only supported when the installation was performed with the dci-openshift-agent.
-
For disconnected environments, it's required to mirror the same operators originally installed in the cluster in order to allow the upgrade to the version used for the upgrade.
-
Please see the ansible-variables section for more settings related to the upgrade process.
Custom Builds
This is a way to test with custom builds. The requirements are:
- Pipeline
- Must NOT contain
ocp
component - Must define:
yaml
dci_custom_component: true
dci_custom_component_file: /path/to/custom_component.json
- Inventory
- Must define a pullsecret with access to the custom build image
yaml
pullsecret_file: /path/to/custom_pullsecret.json
Example of a custom component file:
{
"data": {
"pull_url": "registry.<sub-domain>.ci.openshift.org/<build-id>/release@sha256:abcdef...",
"version": "4.15.0-0.ci.test-<timestamp>-<id>"
},
"tags": [
"sha256:abcdef...",
"build:nightly"
],
"id": "",
"type": "ocp",
"url": "https://registry.<sub-domain>.ci.openshift.org/<build-id>/release:latest"
}
Keep the DCI OCP Agent Updated
It is recommended to keep the Jumpbox server updated, enable dnf-automatic updates to make sure system is using latest dci-openshift-agent
Install dnf-automatic
# dnf install -y dnf-automatic
Modify the default configuration to enable automatic downloads and apply updates
# vi /etc/dnf/automatic.conf
...
download_updates = yes
apply_updates = yes
...
Enable the dnf-automatic.timer
# systemctl enable --now dnf-automatic.timer
Important: DNF automatic updates might fail because of a non-satisfied dependency of latest RHEL 8 with ansible 2.9, then it is recommended to add the following command in a cronjob to be executed daily basis.
# dnf upgrade --nobest --refresh --repo dci,epel -y
