For a control plane installation, it is possible to add custom scripts which can run before and after your build/push process. This is being used to give more flexibility in terms of modifying the total behaviour of the build process and determining the result of the build pipeline.

​
Adding script in the build pipeline

  1. A script can be added before the build and post the build-and-push process.
  2. To do this edit your truefoundry helm chart and configure the section of the tfyBuild.truefoundryWorkflows.preBuild and tfyBuild.truefoundryWorkflows.postBuild
  3. Following is an example 
    tfyBuild:
  truefoundryWorkflows:
    preBuild:
      image:
        tag: latest
        repository: ubuntu
      script: |
        #!/bin/bash

        echo "Running pre-build script..."
        # your steps can come here
        echo "Finishing pre-build script."
      command:
        - /bin/bash
      enabled: true
    postBuild:
      image:
        tag: latest
        repository: ubuntu
      script: |
        #!/bin/bash

        echo "Running post-build script..."
        # your steps can come here
        echo "Finishing post-build script."
      command:
        - /bin/bash
      enabled: true

​
Running time-intensive task

Each build pipeline is allowed to run for max 14400 seconds post which the build will be declared as failed. User needs to ensure that the pre-build and post-build steps don’t exceed the given time. Each step in itself is allowed to run for max 5400 seconds.
  1. Each step can refer to few inputs -
    1. Build Source - {{inputs.parameters.buildSource}}
    2. Build config - {{inputs.parameters.buildConfig}}
    3. Docker registry URL - {{inputs.parameters.dockerRegistryURL}}
    4. Docker registry username - {{inputs.parameters.dockerRegistryUsername}}
    5. Docker registry password - {{inputs.parameters.dockerRegistryPassword}}
    6. Docker image repository - {{inputs.parameters.dockerRepo}}
    7. Docker image tag - {{inputs.parameters.dockerTag}}
  2. An example of using this - 
    postBuild:
  image:
    tag: latest
    repository: ubuntu
  script: >
    #!/bin/bash

    REGISTRY="{{inputs.parameters.dockerRegistryURL}}"  REPOSITORY="{{inputs.parameters.dockerRepo}}" TAG="{{inputs.parameters.dockerTag}}" IMAGE=$REGISTRY/$REPOSITORY:$TAG

    echo "Registry URL is "$REGISTRY
  command:
    - /bin/bash
  enabled: true

Docker cli isn’t supported

Currently docker CLI is not supported in the pre-build script as it can’t connect to any daemon.
