OKD/Openshift collection for Ansible

OKD Collection for Ansible

This repo hosts the community.okd Ansible Collection.

The collection includes a variety of Ansible content to help automate the management of applications in OKD clusters, as well as the provisioning and maintenance of clusters themselves.

Ansible version compatibility

This collection has been tested against following Ansible versions: >=2.9.

Plugins and modules within a collection may be tested with only specific Ansible versions. A collection may contain metadata that identifies these versions. PEP440 is the schema used to describe the versions of Ansible.

Installation and Usage

Installing the Collection from Ansible Galaxy

Before using the OKD collection, you need to install it with the Ansible Galaxy CLI:

ansible-galaxy collection install community.okd

You can also include it in a requirements.yml file and install it via ansible-galaxy collection install -r requirements.yml, using the format:

---
collections:
  - name: community.okd
    version: 1.1.2

Installing the OpenShift Python Library

Content in this collection requires the OpenShift Python client to interact with Kubernetes' APIs. You can install it with:

pip3 install openshift

Using modules from the OKD Collection in your playbooks

It's preferable to use content in this collection using their Fully Qualified Collection Namespace (FQCN), for example community.okd.openshift:

---
plugin: community.okd.openshift
connections:
  - namespaces:
    - testing

For documentation on how to use individual plugins included in this collection, please see the links in the 'Included content' section earlier in this README.

Testing and Development

If you want to develop new content for this collection or improve what's already here, the easiest way to work on the collection is to clone it into one of the configured COLLECTIONS_PATHS, and work on it there.

See Contributing to community.okd.

The tests directory contains configuration for running sanity tests using ansible-test.

You can run the ansible-test sanity tests with the command:

make test-sanity

The molecule directory contains configuration for running integration tests using molecule.

You can run the molecule integration tests with the command:

make test-integration

These commands will create a directory called ansible_collections which should not be committed or added to the .gitignore (Tracking issue: ansible/ansible#68499)

Prow

This repository uses the OpenShift Prow instance for testing against live OpenShift clusters. The configuration for the CI jobs that this repository runs can be found in the openshift/release repository.

The Prow CI integration test job runs the command:

make test-integration-incluster

which will create a job that runs the normal make integration target. In order to mimic the Prow CI job, you must first build the test image using the Dockerfile in ci/Dockerfile. Then, push the image somewhere that it will be accessible to the cluster, and run

IMAGE_FORMAT=<your image> make test-integration-incluser

where the IMAGE_FORMAT environment variable is the full reference to your container (ie, IMAGE_FORMAT=quay.io/example/molecule-test-runner)

Publishing New Versions

Releases are automatically built and pushed to Ansible Galaxy for any new tag. Before tagging a release, make sure to do the following:

1. Update the version in the following places: a. The version in galaxy.yml b. This README's requirements.yml example c. The DOWNSTREAM_VERSION in ci/downstream.sh d. The VERSION in Makefile
2. Update the CHANGELOG: 1. Make sure you have antsibull-changelog installed. 1. Make sure there are fragments for all known changes in changelogs/fragments. 1. Run antsibull-changelog release.
3. Commit the changes and create a PR with the changes. Wait for tests to pass, then merge it once they have.
4. Tag the version in Git and push to GitHub.

After the version is published, verify it exists on the OKD Collection Galaxy page.
