Use Helm template storage backend for PostgreSQL and Mattermost installation

Description

Changes proposed in this pull request:

• Use Helm template storage backend for PostgreSQL and Mattermost installation

Notes

I needed to add a new Implementation for Helm Release, which doesn't require Helm Release storage and (in future) will always produce static Helm Release. I couldn't do it right now because of backward compatibility issues. I extended the scope of the capactio/capact#666.

Testing

1. Run Capact cluster from PR Implement TypeInstance Value Resolver and modify TypeInstance upload capact#697

DISABLE_MONITORING_INSTALLATION=true make dev-cluster

1. Set manifests from my fork:

kubectl set env deploy/capact-hub-public -n capact-system -c hub-public-populator MANIFESTS_SOURCES="github.com/pkosiec/hub-manifests?ref=dynamic-ti-nested-workflows"

1. Install Helm Storage Backends via Dashboard
2. Use ghcr.io/capactio/pr/helm-storage-backend:PR-697 for both Helm template and Helm release container
3. Update Global Policy:

ACTION_NAME="helm-storage" # your Action name which installed Helm storage backends
HELM_RELEASE_STORAGE_ID=$(capact act get $ACTION_NAME -ojson | jq '.Actions[0].output.typeInstances | map(select(.typeRef.path == "cap.type.helm.release.storage"))[0].id' -r)
HELM_TEMPLATE_STORAGE_ID=$(capact act get $ACTION_NAME -ojson | jq '.Actions[0].output.typeInstances | map(select(.typeRef.path == "cap.type.helm.template.storage"))[0].id' -r)

capact ti get $HELM_RELEASE_STORAGE_ID -oyaml
capact ti get $HELM_TEMPLATE_STORAGE_ID -oyaml

cat > /tmp/helm-storage-policy.yaml << ENDOFFILE
interface:
  default: # properties applied to all rules above
     inject:
       requiredTypeInstances:
          - id: ${HELM_TEMPLATE_STORAGE_ID}
            description: "Helm template"
          - id: ${HELM_RELEASE_STORAGE_ID}
            description: "Helm release"
  rules:
      - interface:
          path: cap.*
        oneOf:
        - implementationConstraints:
            requires:
            - path: cap.core.type.platform.kubernetes
        - implementationConstraints: {}
ENDOFFILE
capact policy apply -f /tmp/helm-storage-policy.yaml

1. Run Mattermost installation
