Command to delete all pods in all kubernetes namespaces

Upon looking at the docs, there is an API call to delete a single pod, but is there a way to delete all pods in all namespaces?

#Forcefully complete prune or delete. Assuming foo is our namespace

kubectl delete --all pods --namespace=foo --force

#To keep watch on their removal from the list

watch kubectl get pods -n foo

If you want to delete pods in all namespaces just to have them restarted and you are aware that some of them will be recreated, I like the following for loop:

for i in $(kubectl get pods -A | awk '{print $1}' | uniq | grep -V NAMESPACE); do kubectl delete --all pods -n $i; done

It was hinted at above, but I just thought I would helpfully point out that the shortcut for "--all-namespaces" is "-A" that's with a capital A. HTH somebody. I've opened a PR to have this helpful hint added to the official Kubernetes Cheat Sheet.

steps to delete pv:

  1. delete all deployment and pods or resources related to that PV

     kubectl delete --all deployment -n namespace

 kubectl delete --all pod -n namespace

  2. edit pv

     kubectl edit pv pv_name  -n namespace

 remove kubernetes.io/pv-protection

  3. delete pv

     kubectl delete pv pv_name  -n namespace

There is no command to do exactly what you asked.

Here are some close matches.

Be careful before running any of these commands. Make sure you are connected to the right cluster, if you use multiple clusters. Consider running. kubectl config view first.

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 $each
done

I tried commands from listed answers here but pods were stuck in terminating state.
I found below command to delete all pods from particular namespace if stuck in terminating state or you are not able to delete it then you can delete pods forcefully.

kubectl delete pods --all --grace-period=0 --force --namespace namespace

Hope it might be useful to someone.

K8s completely works on the fundamental of the namespace. if you like to release all the resource related to specified namespace.

you can use the below mentioned :

kubectl delete namespace k8sdemo-app

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.

I create a python code to delete all in namespace

delall.py

import json,sys,os;

obj=json.load(sys.stdin);
for item in obj["items"]:
        os.system("kubectl delete " + item["kind"] + "/" +item["metadata"]["name"] + " -n yournamespace")

and then

kubectl get all -n kong -o json | python delall.py

Kubectl bulk (bulk-action on krew) plugin may be useful for you, it gives you bulk operations on selected resources. This is the command for deleting pods

 ' kubectl bulk pods -n namespace delete '

You could check details in this

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

kubectl get pods -o jsonpath="{.items[*].metadata.name}" | \
tr " " "\n" | \
xargs -i -P 0 kubectl delete pods {}

If you already have pods which are recreated, think to delete all deployments first 

kubectl delete -n *NAMESPACE deployment *DEPLOYMENT

Just replace the NAMSPACE and the DEPLOYMENT to corresponding ones, you can get all deployments information by the following command 

kubectl get deployments --all-namespaces

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.
