build-definitions

This repository contains components that are managed by the Konflux Build Team.

This includes default Pipelines and Tasks. You need to have bootstrapped a working Konflux configuration from (see https://github.com/redhat-appstudio/infra-deployments) for the dev of pipelines or new tasks.

Pipelines and Tasks are delivered into Konflux via the quay organization konflux-ci/tekton-catalog. Pipelines are bundled and pushed into repositories prefixed with pipeline- and tagged with $GIT_SHA (the tag will be updated with every change). Tasks are bundled and pushed into repositories prefixed with task- and tagged with $VERSION, where VERSION is the task version (the tag is updated when the task file contains any change in the PR)

Currently, a set of utilities is bundled with Konflux in quay.io/konflux-ci/appstudio-utils:$GIT_SHA as a convenience, but tasks may be run from different per-task containers.

Building

The script hack/build-and-push.sh creates bundles for pipelines, tasks and the appstudio-utils image. Images are pushed into your quay.io repository. You will need to set QUAY_NAMESPACE to use this feature and be logged into quay.io on your workstation. Once you run the hack/build-and-push.sh, all pipelines will come from your bundle instead of the default one installed by GitOps into the cluster.

Note

If you're using macOS, you need to install GNU coreutils before running the hack/build-and-push.sh script:

brew install coreutils

There is an option to push all bundles to a single quay.io repository (this method is used in PR testing). It is used by setting a TEST_REPO_NAME environment variable. Bundle names are then specified in the container image tag, i.e., quay.io/<quay-user>/$TEST_REPO_NAME:<bundle-name>-<tag>

Pipelines

The pipelines can be found in the pipelines directory.

  • core-services: contains pipelines for the CI of Konflux core services e.g., application-service and build-service.
  • template-build: contains common template used to generate docker-build, fbc-builder and other pipelines.

Tasks

The tasks can be found in the tasks directories. Tasks are bundled and used by bundled pipelines. Tasks are not stored in the cluster. For quick local inner-loop-style task development, you may install new Tasks in your local namespace manually and create your pipelines, as well as the base task image, to test new functionality. Tasks can be installed into the local namespace using oc apply -k tasks/appstudio-utils/util-tasks.

There is a container used to support multiple sets of tasks called quay.io/konflux-ci/appstudio-utils:GIT_SHA. This is a single container used by multiple tasks. Tasks may also be in their own containers as well. However, many simple tasks are utilities and will be packaged for Konflux in a single container. Tasks can rely on other tasks in the system, which are co-packed in a container, allowing combined tasks (build-only vs. build-deploy) that use the same core implementations.

StepActions

Take a look at the Tekton documentation for more information about StepActions.

The StepActions can be found in the stepactions directory. StepActions are not yet bundled.

Versioning

When a task update changes the interface (e.g., change of parameters, workspaces or results names), a new version of the task should be created. The folder with the new version must contain MIGRATION.md with instructions on how to update the current pipeline file in user's .tekton folder.

Adding a new parameter with a default value does not require a task version increase.

Local development

Tasks can have a TA (Trusted Artifact) version. The recommended workflow is to only edit the base version and let the other versions get generated automatically.

./hack/generate-ta-tasks.sh

Buildah also has a remote version, which can be generated with:

./hack/generate-buildah-remote.sh

Testing

Prerequisites

  • Provisioned cluster with sufficient resources
  • Deployed Konflux on the cluster (see infra-deployments)
  1. Set up the image repository PipelineRuns attempt to push to cluster-internal registry image-registry.openshift-image-registry.svc:5000 by default. For testing, you will likely want to use your own Quay repository. Specify the Quay repository using the QUAY_NAMESPACE environment variable in the format OWNER/REPOSITORY_NAME.
  2. Set up the redhat-appstudio-staginguser-pull-secret
    • Log in to quay.io using your credentials: 
      podman login quay.io
      This will create an auth.json file in ${XDG_RUNTIME_DIR}/containers/auth.json, which you will use to create a secret in the cluster.
    • Create the pull secret in you cluster: 
      oc create secret docker-registry redhat-appstudio-staginguser-pull-secret --from-file=.dockerconfigjson=${XDG_RUNTIME_DIR}/containers/auth.json
    • Link the secret to your service account: 
      oc secrets link appstudio-pipeline redhat-appstudio-staginguser-pull-secret
  3. Run the tests

  • To test a custom Git repository and pipeline, use ./hack/test-build.sh.

    Usage example:

    QUAY_NAMESPACE=OWNER/REPOSITORY_NAME ./hack/test-build.sh https://github.com/jduimovich/spring-petclinic java-builder`.

  • To run tests on predefined Git repositories and pipelines, use:

    QUAY_NAMESPACE=OWNER/REPOSITORY_NAME ./hack/test-builds.sh

  • Shellspec tests can be run by invoking:

    ./hack/test-shellspec.sh`

Compliance

Task definitions must comply with the Enterprise Contract policies. Currently, there are two policy configurations.

  • The all-tasks policy configuration applies to all Task definitions
  • The build-tasks policy configuration applies only to build Task definitions.

A build Task, i.e., one that produces a container image, must abide by both policy configurations.
