It seems that the config-manager command is no longer installed by
default in the latest centos8 image, which results in this failure:
No such command: config-manager. Please use /usr/bin/yum --help
It could be a YUM plugin command, try: "yum install 'dnf-command(config-manager)'"
We use the config-manager command to inject the openshift-ansible rpm
into the ci image. For more details, see:
https://github.com/openshift/openshift-ansible/pull/10960
using the "--no-cache-dir" flag in pip install, make sure downloaded packages by pip don't cache on the system. This is a best practice that makes sure to fetch from a repo instead of using a local cached one. Further, in the case of Docker Containers, by restricting caching, we can reduce image size. In terms of stats, it depends upon the number of python packages multiplied by their respective size. e.g for heavy packages with a lot of dependencies it reduces a lot by don't cache pip packages.

This moves all core functionality into the openshift-ansible repo, adds
the necessary equivalent entrypoint to the openshift-ansible installer
image, and ensures the dynamic inventory mechanisms in openshift-ansible
continue to work.
Notable changes from origin-gce:
* playbook extensions changed to .yml
* dynamic inventory subdirectory created to prevent accidental use
* use the custom entrypoint entrypoint-gcp for this image
* move tasks into openshift_gcp role
There are modules in openshift-ansible that depend on boto3 (I see lib_utils/library/oo_iam_kms and lib_utils/library/oo_ec2_group). Add the dependency so that the origin-ansible container can succesfully run these modules.
The installer image will become our default cloud operations image for
tasks that overlap with ansible, and will also be the image for
provioning. We will eventually add others like awscli for support roles.
The oc client was left out with the move away from playbook2image.
However it is needed in the image for the `oc cluster up` use case for
installing logging or metrics.
This change adds oc via the latest signed and released client RPM,
which requires adding the centos-openshift-origin repo to the image.
As discussed in #4279 the container image is being renamed to
openshift/origin-ansible (upstream) and openshift3/ose-ansible (downstream) for
the "oc cluster up" use case, and more generally to make it fit the
imageConfig.format configuration option.
This updates references to the image name accordingly.
Also updating references to playbook2image to account for recent moves of the
repo/image.
Updating some files to account for recent changes:
- Commit fbadeb4 moved the location of the Dockerfiles
- playbook2image is now available from the openshift org
- downstream image is building with boto 2.34
Adjusting image build scripts and documentation to match these changes.
