CentOS CI - On-boarding

Note to users:

Please note that Infra space is for Fedora and CentOS related projects to consume. Decision may take some time (often up to 2 weeks) as these are decided by the whole team. Once decided as go, we will create you a namespace in a openshift cluster where you can configure your CI. We do provide a Jenkins template in case you want to be able to consume vms/baremetal nodes to perform your CI.

Please answer the following questions so that we understand your requirement.

• How does your project relates to Fedora/CentOS?
• Describe your work flow and if you need any special permissions (other than admin access to namespace), please tell us and provide a reason for them.
• Do you need bare-metal/vms checkout capability? (we prefer your workflow containerized)
• Resources required
• PVs:

Project_name:
Project_members:
 - user1@ACO_registered_email_address
 - user2@ACO_registered_email_address

Steps

1. Create an OpenShift namespace
2. Create an entry in duffy db (with ssh key) - follow adding-duffy-api-key.md
3. Create a PV(Persistent Volume) for Jenkins instance
4. Instantiate a template to provision Jenkins

Create an OpenShift namespace

Using the data provided by tenant (i.e. Project name and its admins), create an yaml file to be passed to ansible-playbook (example above).

Store it in project directory to and push it to git

Use playbook (adhoc-openshift-resources.yaml)[https://github.com/CentOS/ansible-infra-playbooks/blob/staging/adhoc-openshift-resources.yaml] with variables host=openshift-ci-management and the file containing project name and admins

Example: "ansible-playbook playbooks/adhoc-openshift-resources.yaml -e "host=ocp-ci-management" -e "@important_project.yaml""

Create an entry in duffy db (with ssh key) - follow adding-duffy-api-key.md

Create a PV(Persistent Volume) for Jenkins instance

The default PV size for Jenkins instance is 10Gi. If a volume of a different size is created it will need to be reflected in the next section

To create the PV follow Persistent storage via NFS. The host will be ocp-ci-management

Instantiate a template to provision Jenkins

• Login to openshift
• Ensure you are in Developer mode and select +Add from the menu
• At the top select the Project cico-templates from the dropdown
• Under the Developer Catalog section select All Services
• Enter cico-workspace in the search field you will see a template called "cico-workspace: provided by The CentOS Project"
• Click the template to start instantiation process.
• Select the namespace we want to run Jenkins in (In Namespace variable)
• Enter appropriate Memory limit and volume capacity (for Jenkins, we prefer 3Gi and 10Gi respectively)
• Enter duffy API key for the project and SSH private key whose public pair is in duffy db.

Click create to instantiate the project.

Admin's hack: Increase timeout in deployment config to counter our slow storage timeout issue.
