Scenario-10

This docs trying to explain the behavior of Pack

This section explain how jsonnet appears Pack, more complex situation than scenario-9

Above diagram shows the dependency chain. Here,

• test-10 depend on repository kube-a (branch test-10).
• kube-a depends on repository kube-b (branch test-10). Also, contains a jsonnet file.
• kube-b depends on repository kube-c (branch test-10). Also, contains a patch of yaml file from kube-a repository. This yaml is generated from jsonnet file.
• kube-c depend on nothing.

See dependency-list.yaml file below:

    $ cat dependency-list.yaml

    items:
    - package: github.com/kubepack/kube-a
      branch: test-10

Get Dependencies

$ pack dep -f . command gets all the dependencies and place it under manifests/vendor folder. In this scenario, following things happen:

• kube-b repository contains patch of jsonnet file’s yaml, so kube-c’s jsonnet will be yaml. This yaml is combination of jsonnet’s yaml and this yaml’s patch which exists in kube-b repository.
• kube-a contains a jsonnet file. In manifests/vendor folder, this jsonnet file will be converted into yaml file.

Now, $ pack up -f . command will generate the final output in manifests/output folder.

    $ tree manifests/output/
