radix-operator

The radix-operator is the central piece of the Radix platform which fully manages the Radix platform natively on Kubernetes. It manages seven custom resource definitions:

• RR - Application registrations
• RA - Application definition/configuration
• RD - Application deployment
• RJ - Application build/deploy jobs
• RE - Application environments
• RAL - Alerts
• RB - Batch jobs

The radix-operator and radix-pipeline are built using Github actions, then the radix-operator is deployed to cluster through a Helm release using the Flux Operator whenever a new image is pushed to the container registry for the corresponding branch. Build and push to container registry is done using Github actions.

Development Process

The radix-operator project follows a trunk-based development approach.

🔁 Workflow

• External contributors should:

  • Fork the repository
  • Create a feature branch in their fork

• Maintainers may create feature branches directly in the main repository.

Generating mocks

We use gomock to generate mocks used in unit test. You need to regenerate mocks if you make changes to any of the interface types used by the application:

make mocks

Updating Radix CRD types

The client-go SDK requires strongly typed objects when dealing with CRDs so when you add a new type to the spec, you need to update pkg/apis/radix/v1/types.go typically. In order for these objects to work with the SDK, they need to implement certain functions and this is where you run the code-generator tool from Kubernetes. Generate the strongly type client for Radix v1 objects. code-gen will automatically install the required tooling:

make code-gen

This will generate pkg/apis/radix/v1/zz_generated.deepcopy.go and pkg/client directory.

This file/directory should NOT be edited.

CRD yaml files are generated with [controller-gen(https://pkg.go.dev/sigs.k8s.io/controller-tools/cmd/controller-gen), and are stored in the charts/radix-operator/templates directory. The CRD schema generates use comment markers. Read more about supported markers here. Generate CRD yaml files whenever you make changes to any of the types in pkg/apis/radix/v1/.

Currently, only the CRD for RadixBatch and RadixApplication is generated.

make crds

This will also regenerate a json schema for RadixApplication into ./json-schema/radixapplication.json. This schema can be used in code editors like VS Code to get auto complete and validation when editing a radixconfig.yaml file.

✅ Merging Changes

All changes must be merged into the master branch using pull requests with squash commits.

The squash commit message must follow the Conventional Commits specification.

Release Process

Merging a pull request into master triggers the Prepare release pull request workflow.
This workflow analyzes the commit messages to determine whether the version number should be bumped — and if so, whether it's a major, minor, or patch change.

It then creates two pull requests:

• one for the new stable version (e.g. 1.2.3), and
• one for a pre-release version where -rc.[number] is appended (e.g. 1.2.3-rc.1).

Merging either of these pull requests triggers the Create releases and tags workflow.
This workflow reads the version stored in version.txt, creates a GitHub release, and tags it accordingly.

The new tag triggers the Build and deploy Docker and Helm workflow, which:

• builds and pushes a new container image and Helm chart to ghcr.io, and
• uploads the Helm chart as an artifact to the corresponding GitHub release.
