Kubernetes

Overview

Operate cluster resources with explicit namespaces and GitOps manifests. Use CNPG for Postgres access and Helm v3 for kustomize when required.

Namespace discipline

Always specify -n jangar for the Jangar stack unless a different namespace is required.

Common operations

kubectl get pods -n jangar
kubectl logs -n jangar deploy/bumba --tail=200
kubectl rollout status -n jangar deployment/bumba

Exec and port-forward

kubectl exec -n jangar deploy/bumba -- env | rg TEMPORAL
kubectl -n jangar port-forward svc/open-webui 8080:80

CNPG (Postgres)

kubectl cnpg psql -n jangar jangar-db -- -c 'select now();'

Helm-enabled kustomize

mise exec helm@3 -- kustomize build --enable-helm argocd/applications/jangar | kubectl apply -n jangar -f -
