==Restarting your cluster== | |||
===Scale to 0=== | |||
[https://stackoverflow.com/questions/64133011/scale-down-kubernetes-deployments-to-0-and-scale-back-to-original-number-of-repl reference]<br> | |||
If you wish to restart your cluster, you can scale your deployments and stateful sets down to 0 and then scale them back up after. | |||
<pre> | |||
# Annotate existing deployments and statefulsets with replica count. | |||
kubectl get deploy -o jsonpath='{range .items[*]}{"kubectl annotate --overwrite deploy "}{@.metadata.name}{" previous-size="}{@.spec.replicas}{" \n"}{end}' | sh | |||
kubectl get sts -o jsonpath='{range .items[*]}{"kubectl annotate --overwrite deploy "}{@.metadata.name}{" previous-size="}{@.spec.replicas}{" \n"}{end}' | sh | |||
# Scale to 0. | |||
# shellcheck disable=SC2046 | |||
kubectl scale --replicas=0 $(kubectl get deploy -o name) | |||
# shellcheck disable=SC2046 | |||
kubectl scale --replicas=0 $(kubectl get sts -o name) | |||
# Scale back up. | |||
kubectl get deploy -o jsonpath='{range .items[*]}{"kubectl scale deploy "}{@.metadata.name}{" --replicas="}{.metadata.annotations.previous-size}{"\n"}{end}' | sh | |||
kubectl get sts -o jsonpath='{range .items[*]}{"kubectl scale deploy "}{@.metadata.name}{" --replicas="}{.metadata.annotations.previous-size}{"\n"}{end}' | sh | |||
