Execute bash command in pod with kubectl?

Question

my question is simple.

How to execute a bash command in the pod? I want to do everything with one bash command?

[root@master ~]# kubectl exec -it --names         


        

Answer 1

The double dash symbol "--" is used to separate the arguments you want to pass to the command from the kubectl arguments. So the correct way is:

kubectl exec -it --namespace=tools mongo-pod -- bash -c "mongo"

You forgot a space between "--" and "bash".

To execute multiple commands you may want:

• to create a script and mount it as a volume in your pod and execute it

• to launch a side container with the script and run it

Answer 2

I use something like this for get into the pod's shell:

kubectl exec -it --namespace develop pod-name bash

then you can execute the command you want within the pod (e.g. ping)
