Comand for stern

[robinge330]

Please could you guide the syntax to use
root@compute2:# docker run ghcr.io/stern/stern:latest stern -n magma
invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable
root@compute2:#

You have to pass your KUBECONFIG file to docker container and specify it.

If KUBECONFIG file is in $HOME/.kube/config , you can execute it like this.

$ docker run --rm \
  --mount type=bind,readonly,source=$HOME/.kube,target=/.kube \
  -e KUBECONFIG=/.kube/config \
  ghcr.io/stern/stern:latest -n default .

root@compute1:~# docker run --rm --mount type=bind,readonly,source=$HOME/.kube,target=/.kube -e KUBECONFIG=/.kube/config ghcr.io/stern/stern:latest -n magma
Tail multiple pods and containers from Kubernetes

Usage:
stern pod-query [flags]

Flags:
-A, --all-namespaces If present, tail across all namespaces. A specific namespace is ignored even if specified with --namespace.

This is the output of this
yes $HOME/.kube/config does exists

You need to pass pod-query like this

docker run --rm \
  --mount type=bind,readonly,source=$HOME/.kube,target=/.kube \
  -e KUBECONFIG=/.kube/config \
  ghcr.io/stern/stern:latest -n magma .

( . means all pods)
