Introduce Helm storage backends installation manifests

[pkosiec]

Description

Changes proposed in this pull request:

• Introduce Helm storage backends installation manifests

Notes

This PR bases on #62, however it assumes the path of the Type manifest is different.

Testing

Option A: UI

1. Navigate to the UI, select Helm Storage installation and create Action from it. Run it and wait for output.
2. Repeat the same steps, but with "Advanced configuratiom" - modify additionalInput and run the Action.

Option B: CLI

Prerequisites

1. Checkout this branch.
2. Run Capact
3. Set manifest location to my fork

kubectl set env deploy/capact-hub-public -n capact-system -c hub-public-populator MANIFESTS_SOURCES="github.com/pkosiec/hub-manifests?ref=helm-storage-manifests"

4. Wait until the manifests are populated

Create & run Action

1. Create Parameters:

   cat > /tmp/helm-storage-input-params.yaml << ENDOFFILE
   input-parameters: {}
   ENDOFFILE

2. Create Action:

   capact act create cap.interface.helm.storage.install --name helm-storage -n capact-system --parameters-from-file /tmp/helm-storage-input-params.yaml

3. Wait for the Action to have the READY_TO_RUN status:

   capact act get helm-storage -n capact-system

4. Run Action:

   capact act run helm-storage -n capact-system

5. Watch the Action for completion:

   capact act watch helm-storage -n capact-system

6. Get output TypeInstances:

   capact act get helm-storage -n capact-system -ojson | jq '.Actions[0].output.typeInstances'

   See the details of the installed Helm release backend:

   HELM_RELEASE_STORAGE_ID=$(capact act get helm-storage -n capact-system -ojson | jq '.Actions[0].output.typeInstances | map(select(.typeRef.path == "cap.type.helm.release.storage"))[0].id' -r)
   capact ti get $HELM_RELEASE_STORAGE_ID -oyaml

   See the details of the installed Helm template backend:

   HELM_TEMPLATE_STORAGE_ID=$(capact act get helm-storage -n capact-system -ojson | jq '.Actions[0].output.typeInstances | map(select(.typeRef.path == "cap.type.helm.template.storage"))[0].id' -r)
   capact ti get $HELM_TEMPLATE_STORAGE_ID -oyaml

You can also run this Action with Action policy to set up additional Parameters. For example, you can pass the following Action Policy:

interface:
  rules:
    - interface:
        path: cap.interface.helm.storage.install
      oneOf:
        - implementationConstraints:
            path: cap.implementation.helm.storage.install
          inject:
            additionalParameters:
              - name: additional-parameters

                    requests:

                      memory: 16Mi

                  tolerations: []
    - interface:
        path: cap.*
      oneOf:
        - implementationConstraints:
            requires:
              - path: cap.core.type.platform.kubernetes

But, the easiest way is to do it from UI 🙂
