You first need to login. Do:

## RHEL8 Entitlements
Create a project/namespace where you will create your images
To build the RAN images, we use the `codeready-builder-for-rhel-8-x86_64-rpms` repository with all the proper development libraries.
This repository is not directly accessible from the UBI RHEL8 image (`registry.access.redhat.com/ubi8/ubi:latest`).
Therefore, we need to copy certificates and subscription manager configuration files from a registered RHEL8 machine.
```bash
oc new-project oaicicd-ran
```
on a `RHEL8` physical machine (or a virtual machine) connected to the OpenShift Cluster, recover the entitlement and the RH subscription manager configs:
**NOTE**: If you change the project name then you have to change it in all the `yaml` files.
## RHEL9 Entitlements
To build the RAN images, we use the `codeready-builder-for-rhel-9-x86_64-rpms`
repository with all the proper development libraries. To access the library you
will need `etc-pki-entitlement` inside the container image.
To import `etc-pki-entitlement` in your project follow this
[guide](https://docs.openshift.com/container-platform/4.14/cicd/builds/running-entitled-builds.html#builds-source-secrets-entitlements_running-entitled-builds)
In case you have difficulties in following it then you can copy the
certificates from an RHEL9 host
```bash
oc create configmap rhsm-conf --from-file /etc/rhsm/rhsm.conf
oc create configmap rhsm-ca --from-file /etc/rhsm/ca/redhat-uep.pem
oc create secret generic etc-pki-entitlement --from-file /etc/pki/entitlement/{NUMBER_ON_YOUR_COMPUTER}.pem --from-file /etc/pki/entitlement/{NUMBER_ON_YOUR_COMPUTER}-key.pem
```
These configmaps and secret will be shared by all the build configs in your OC
project. No need to do it each time. However, these files expire every month
or so. If you have done a build on your OC project and try again a few weeks
later, you may need to re-copy them. (The CI recopies them every time.)
```bash
oc delete secret etc-pki-entitlement
oc delete cm rhsm-conf
oc delete cm rhsm-ca
```
# 2. Build of `base` shared image
Create an image stream and build config that specify image properties and build parameters, then start the build:
