问题
I am using GKE. I've launched the following traefik deployment through kubectl:
https://github.com/containous/traefik/blob/master/examples/k8s/traefik-deployment.yaml
The pod runs on the kube-system namespace. I'm not able to ssh into the pod.
kubectl get po -n kube-system
traefik-ingress-controller-5bf599f65d-fl9gx 1/1 Running 0 30m
kubectl exec -it traefik-ingress-controller-5bf599f65d-fl9gx -n kube-system -- '\bin\bash'
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"\\\\bin\\\\bash\": executable file not found in $PATH"
command terminated with exit code 126
Am I missing something? The same thing for '-- sh' too.
回答1:
rather use forward slashed / (your example has a backslash) such as in
kubectl exec -it traefik-ingress-controller-5bf599f65d-fl9gx -n kube-system -- '/bin/bash'
If this does still not work, try a different shell such as
kubectl exec -it traefik-ingress-controller-5bf599f65d-fl9gx -n kube-system -- '/bin/sh'

So, apparently the default traefik image is an amd64 version. I had to use the alpine version to ssh into it using:
kubectl exec -it _podname_ -- sh

It seems that this here is the right answer. You cannot exec a shell into the traefik container using the default image, you must use the alpine one.
