Repository storing ArgoCD configurations for my personal K8s cluster running in OKE

Infrastructure

Infrastructure as Code via Terraform is maintained in bkonicek/terraform

Bootstrapping

1. Assuming you have a running cluster, install the latest ArgoCD release

   kubectl create namespace argocd
   kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/{VERSION}/manifests/install.yaml
   

2. Update

   gitops/core/argocd/kustomization.yaml

   Line 7 in 8e3afc7

   - https://raw.githubusercontent.com/argoproj/argo-cd/v2.8.4/manifests/install.yaml

   with the same release version that you installed in step 1, and commit it to the repo.

3. Apply the root app-of-apps Application

kubectl apply -f application.yaml

Additional Requirements

• If installing on a new cluster, and you want to reuse the same sealed-secrets cert and private key, you have to update the Secret after sealed-secrets is successfully installed.
  • kubectl edit secret -n kube-system sealed-secrets-key
  • Replace tls.crt and tls.key with the old values from a previous installation
  • Restart the sealed-secrets pod(s) kubectl rollout restart -n kube-system deployment sealed-secrets-controller
