Command to delete all pods in all kubernetes namespaces

There is no command to do exactly what you asked.

Here are some close matches.

You can delete all the pods in a single namespace with this command:

kubectl delete --all pods --namespace=foo

You can also delete all deployments in namespace which will delete all pods attached with the deployments corresponding to the namespace

kubectl delete --all deployments --namespace=foo

You can delete all namespaces and every object in every namespace (but not un-namespaced objects, like nodes and some events) with this command:

kubectl delete --all namespaces

However, the latter command is probably not something you want to do, since it will delete things in the kube-system namespace, which will make your cluster not usable.

This command will delete all the namespaces except kube-system, which might be useful:

for each in $(kubectl get ns -o jsonpath="{.items[*].metadata.name}" | grep -v kube-system);do  kubectl delete ns $eachdone

kubectl delete daemonsets,replicasets,services,deployments,pods,rc --all

to get rid of them pesky replication controllers too.

You can simply run

kubectl delete all --all --all-namespaces

• The first all means the common resource kinds (pods, replicasets, deployments, ...)

  • kubectl get all == kubectl get pods,rs,deployments, ...

• The second --all means to select all resources of the selected kinds

Note that all does not include:

• non namespaced resourced (e.g., clusterrolebindings, clusterroles, ...)
• configmaps
• rolebindings
• roles
• secrets
• ...

In order to clean up perfectly,

• you could use other tools (e.g., Helm, Kustomize, ...)
• you could use a namespace.
• you could use labels when you create resources.
