AWX-Operator Contributing Guidelines

Hi there! We're excited to have you as a contributor.

Have questions about this document or anything not covered here? Please file a new at https://github.com/ansible/awx-operator/issues.

Table of contents

Things to know prior to submitting code

  • All code submissions are done through pull requests against the devel branch.
  • All PRs must have a single commit. Make sure to squash any changes into a single commit.
  • Take care to make sure no merge commits are in the submission, and use git rebase vs git merge for this reason.
  • If collaborating with someone else on the same branch, consider using --force-with-lease instead of --force. This will prevent you from accidentally overwriting commits pushed by someone else. For more information, see https://git-scm.com/docs/git-push#git-push---force-with-leaseltrefnamegt
  • We ask all of our community members and contributors to adhere to the Ansible code of conduct. If you have questions, or need assistance, please reach out to our community team at [email protected]

Submmiting your work

  1. From your fork devel branch, create a new brach to stage your changes.
#> git checkout -b <branch-name>
  1. Make your changes.
  2. Test your changes according described on the Testing section.
  3. If everylooks looks correct, commit your changes.
#> git add <FILES>
#> git commit -m "My message here"
  1. Create your pull request

Note: If you have multiple commits, make sure to squash your commits into a single commit which will facilitate our release process.

Testing

This Operator includes a Molecule-based test environment, which can be executed standalone in Docker (e.g. in CI or in a single Docker container anywhere), or inside any kind of Kubernetes cluster (e.g. Minikube).

You need to make sure you have Molecule installed before running the following commands. You can install Molecule with:

#> pip install 'molecule[docker]'

Running molecule test sets up a clean environment, builds the operator, runs all configured tests on an example operator instance, then tears down the environment (at least in the case of Docker).

If you want to actively develop the operator, use molecule converge, which does everything but tear down the environment at the end.

Testing in Docker

#> molecule test -s test-local

This environment is meant for headless testing (e.g. in a CI environment, or when making smaller changes which don't need to be verified through a web interface). It is difficult to test things like AWX's web UI or to connect other applications on your local machine to the services running inside the cluster, since it is inside a Docker container with no static IP address.

Testing in Minikube

#> minikube start --memory 8g --cpus 4
#> minikube addons enable ingress
#> molecule test -s test-minikube

Minikube is a more full-featured test environment running inside a full VM on your computer, with an assigned IP address. This makes it easier to test things like NodePort services and Ingress from outside the Kubernetes cluster (e.g. in a browser on your computer).

Once the operator is deployed, you can visit the AWX UI in your browser by following these steps:

  1. Make sure you have an entry like IP_ADDRESS example-awx.test in your /etc/hosts file. (Get the IP address with minikube ip.)
  2. Visit http://example-awx.test/ in your browser. (Default admin login is test/changeme.)

Alternatively, you can also update the service awx-service in your namespace to use the type NodePort and use following command to get the URL to access your AWX instance:

#> minikube service <serviceName> -n <namespaceName> --url

Generating a bundle

⚠️ operator-sdk version 0.19.4 is needed to run the following commands

If one has the Operator Lifecycle Manager (OLM) installed, the following steps is the process to generate the bundle that would nicely display in the OLM interface.

At the root of this directory:

  1. Build and publish the operator
#> operator-sdk build registry.example.com/ansible/awx-operator:mytag
#> podman push registry.example.com/ansible/awx-operator:mytag
  1. Build and publish the bundle
#> podman build . -f bundle.Dockerfile -t registry.example.com/ansible/awx-operator-bundle:mytag
#> podman push registry.example.com/ansible/awx-operator-bundle:mytag
  1. Build and publish an index with your bundle in it
#> opm index add --bundles registry.example.com/ansible/awx-operator-bundle:mytag --tag registry.example.com/ansible/awx-operator-catalog:mytag
#> podman push registry.example.com/ansible/awx-operator-catalog:mytag
  1. In your Kubernetes create a new CatalogSource pointing to registry.example.com/ansible/awx-operator-catalog:mytag
---
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: <catalogsource-name>
  namespace: <namespace>
spec:
  displayName: 'myoperatorhub'
  image: registry.example.com/ansible/awx-operator-catalog:mytag
  publisher: 'myoperatorhub'
  sourceType: grpc

Applying this template will do it. Once the CatalogSource is in a READY state, the bundle should be available on the OperatorHub tab (as part of the custom CatalogSource that just got added)

  1. Enjoy
