kube/argocd

Most applications in our Kubernetes cluster are managed by ArgoCD. Most notably operators are NOT managed by ArgoCD.

Managing applications

Update apps (see TODO below):

cat << EOF >> applications/$j.yaml

Cold start

Normally ArgoCD deploys itself. Deploy ArgoCD out-of-bounds:

kustomize build . --enable-helm | kubectl apply -f -

ArgoCD dependencies:

• dragonfly (database)
• passmower (auth)
• traefik
• #TODO: network...
• gitea
