TAP Operator

Tanzu Application Platform (TAP) operator manages the following tasks:

• Relocating Tanzu packages to turn your TAP installation independant.
  • copy TAP Essential packages from tanzu registry to a local registry (Carvel Operators)
  • copy TAP packages from tanzu registry to a local registry
  • copy PostgresSQL from tanzu registry to a local registry
• Deploy TAP Essential in the cluster (kapp-control, secret-gen-control) (thanks @alexandreroman tanzu-cluster-essentials-bootstrap )
• Deploy an App to trigger the TAP Gitops installation and all the necessary configuration
• Generate default configuration to manage GitOps deployment (see below for details). These 2 files are injected in the sync app after the values folder (so it can be override)
  • the sensitive-image-registry secret containing the target registry with the credentials used to manage the deployment of TAP that will be used a the target registry for built project
  • the tap-install-values config map that includes the current version info.

Installation

Prepare a secret registry-secrets.yaml following this template

apiVersion: v1
kind: Secret
metadata:
  name: tap-operator-registry-credentials
  namespace: tanzu-sync
type: Opaque
stringData:
  FROM_REGISTRY_HOSTNAME: registry.tanzu.vmware.com
  FROM_REGISTRY_USERNAME: #@ data.values.TANZU_USERNAME
  FROM_REGISTRY_PASSWORD: #@ data.values.TANZU_PASSWORD
  TO_REGISTRY_HOSTNAME: #@ data.values.HOSTNAME
  TO_REGISTRY_USERNAME: #@ data.values.USERNAME
  TO_REGISTRY_PASSWORD: #@ data.values.PASSWORD
  AGE_SECRET_KEY: AGE-SECRET-KEY-123skjldjflkqsjlkdsjlkjdslkjdlkfjskldjflksjfjs  
  GIT_SSH_PRIVATEKEY: #@ data.values.PRIVATE_KEY
  GIT_SSH_KNOWNHOSTS: //Computed for a GitRepository managed on public GitHub.com

git clone git@github.com:bmoussaud/tap-operator.git
vi registry-secrets.yaml
kubectl apply -f config

Usage

Minimal configuration

apiVersion: org.moussaud.tanzu/v1
kind: TapResource
metadata:
  name: mytap
  namespace: tanzu-sync
spec:
  version: 1.7.0  
  url: git@github.com:bmoussaud/tap-gitops.git
  subPath: clusters/empty/cluster-config
  

Full configuration

apiVersion: org.moussaud.tanzu/v1
kind: TapResource
metadata:
  name: mytap
  namespace: tanzu-sync
spec:
  version: 1.7.0
  clusterEssentialsBundleVersion: 1.7.0
  postgresVersion: 1.12.1
  secret: my-tap-operator-registry-credentials
  url: git@github.com:bmoussaud/tap-gitops.git
  subPath: clusters/empty/cluster-config

if not provided the clusterEssentialsBundleVersion property is computed to get latest value for a given version the secret property contains the name of secret holding the image registry property.

The generated config map

apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    app.kubernetes.io/component: tap-version
    app.kubernetes.io/managed-by: tap-operator
    app.kubernetes.io/name: mytap
  name: mytap-tap-version

apiVersion: v1
data:
  values.yaml: |
    ---
    tap_operator:
      tap_version: "1.8.0-build.68"

The deployed TAP configuration can use #@ data.values.tap_install.values.tap_version to manage the version
