Upon looking at the doc there is an api call to delete 'a' pod , is there a way to kill all pods in all 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 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 $each
done

kubectl Cheat Sheet, What happened: kubectl delete namespace --namespace= --all deletes all The above command should throw an error since --namespace and --all are kubectl delete pods --all deletes all pods in current namespace; the  kubectl --all-in-namespace[=ns] that is specifically a safer alternative to --all, refusing to match any cluster-global resources in same command. Using this doesn't cover the case of specific names given on command line — kubectl delete nodes,pods f00-ba7 can match both a node and a pod that happen to be named f00-ba7. But that's less likely to cause harm in practice

You just need sed to do this:

kubectl get pods --no-headers=true --all-namespaces |sed -r 's/(\S+)\s+(\S+).*/kubectl --namespace \1 delete pod \2/e'

Explains:

  1. use command kubectl get pods --all-namespaces to get the list of all pods in all namespaces.
  2. use --no-headers=true option to hide the headers.
  3. use s command of sed to fetch the first two words, which represent namespace and pod's name respectively, then assemble the delete command using them.
  4. the final delete command is just like: kubectl --namespace kube-system delete pod heapster-eq3yw.
  5. use the e modifier of s command to execute the command assembled above, which will do the actual delete works.

To avoid delete pods in kube-system namespace, just need to add grep -v kube-system to exclude kube-system namespace before the sed command.

Here is a one-liner that can be extended with grep to filter by name.

Comments
  • ""{.items[*].metadata.name}" - there are double quotes present in this answer...please check and edit.
  • fixed the quote
  • With the current version of k8s, the command "kubectl delete --all namespaces" does not delete the system stuff anymore... It says e.g.: namespaces "default" is forbidden: this namespace may not be deleted
  • Does this delete the deployment or just the pods?
  • kubectl delete pods --all --all-namespaces seems to work sometimes (not sure what causes it to work in some environments and not in others). It works well from my bastion host but not from laptop. Both running debian and both running the same version of kubectl (cluster version 1.13)
  • This is wrong. This only deletes in the current namespace.
  • Add the -n flag, but sorry that's for one pod at a time and not all at once
  • You are missing ing to also delete ingresses
  • you might want to add "statefulset" as well ( if applicable ). Otherwise it will keep forking new pods even after you run above command!
  • You can also just drop --all-namespaces if you don't want to delete pods in the kube-system namespace
  • What will be the command to delete only few pod? Example: I had spin 20 Pod and now wish to keep just 1.
