Kubernetes – Pausing Applications by Scaling Deployments or Stateful Sets

# Pause application
kubectl scale deploy nextcloud --replicas=0
kubectl scale statefulsets nextcloud-db-postgresql --replicas=0
kubectl scale deploy pihole --replicas=0

# Resume application
kubectl scale deploy nextcloud --replicas=1
kubectl scale statefulsets nextcloud-db-postgresql --replicas=1
kubectl scale deploy pihole --replicas=1

# Alternate for deployments scaling
kubectl scale deploy -n default --replicas=0 --all
kubectl scale deploy -n default --replicas=1 --all
