Add Environment to Apps GitOps Repository

Lets see how can we add an environment to an application in a tenant. Lets say, we have added a production cluster and want to add a new environment in application for it to be deployed on production.

Objectives

• Deploy your application to a new environment

Key Results

• ArgoCD apps pointing to application environment created
• Helm chart with production configuration deployed

Guide

1. Create a folder named production at <tenant-name>/<app-name> which corresponds to the production environment. Suppose gabbar as tenant name, stakater-nordmart-review as application name, production as cluster name, prod as environment name.

└── gabbar
    └── stakater-nordmart-review
        └── prod

1. Add the Helm Chart of your application with production environment configurations.

└── gabbar
    └── stakater-nordmart-review
        └── prod
            ├── Chart.yaml
            ├── values.yaml
            └── templates/

1. Add a folder prod inside <tenant-name>/argocd-apps. Add an ArgoCD Application in this folder which points to <tenant-name>/<app-name>/prod.

# Name: stakater-nordmart-review.yaml(APP_NAME.yaml)
# Path: gabbar/argocd-apps/prod (TENANT_NAME/   argocd-apps/ENV_NAME/)
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: gabbar-prod-stakater-nordmart-review
  namespace: openshift-gitops
spec:
  destination:
    namespace: TARGET_NAMESPACE
    server: 'https://kubernetes.default.svc'
  project: gabbar
  source:
    path: gabbar/stakater-nordmart-review/prod
    repoURL: 'APPS_GITOPS_REPO_URL'
    targetRevision: HEAD
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

1. Add a folder called production (if not present) corresponding to the cluster name inside argocd-apps at root level, Add an ArgoCD Application in this folder which points to <tenant-name>/argocd-apps/prod.

# Name: gabbar-prod.yaml (TENANT_NAME-ENV_NAME.yaml)
# Path: argocd-apps/prod
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: gabbar-prod
  namespace: openshift-gitops
spec:
  destination:
    namespace: TARGET_NAMESPACE
    server: 'https://kubernetes.default.svc'
  project: gabbar
  source:
    path: gabbar/argocd-apps/prod
    repoURL: 'APPS_GITOPS_REPO_URL'
    targetRevision: HEAD
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

1. You should have a similar folder structure at the end:

├── gabbar
|   ├── stakater-nordmart-review
|   |   ├── prod
|   |   |   ├── Chart.yaml
|   |   |   ├── values.yaml
|   |   └── └── templates/
├── └── argocd-apps
|       └── prod
|            └── stakater-nordmart-review.yaml
└── argocd-apps
    └── production (cluster name)
        └── gabbar-prod.yaml

1. Make sure Application that deploys applications inside argocd-apps/cluster-name/ folder is deployed in relevant infra-gitops-config repository.
