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

Exec and port-forward

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

CNPG (Postgres)

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

Helm-enabled kustomize
