# 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](https://docs.infra.centos.org/operations/ci/adding_cico_tenant/adding-duffy-api-key/)
## 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](https://docs.infra.centos.org/operations/ci/installation/persistant_storage_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.
