在 k8s 上的“Traefik”Pod 中获取运行容器的 Shell

Question

We tried attaching a shell to container inside "Traefik" Pod using following command but it didn't work. Just FYI, we used helm chart to install Traefik on our k8s cluster.

kubectl exec -it <traefik Pod name> -- /bin/sh

tried this too but no success - kubectl exec -it <traefik Pod name> -- /bin/bash

Any help in this context will be appreciated. Thanks.

Answer 1

Traefik 1.7 uses a FROM scratch container image that has only the Traefik executable and some support files. There is no shell. You would have to switch to the -alpine variant of the image. For 2.x it looks like they use Alpine by default for some reason.

Answer 2

You can change the time zone by mounting volume

volumes:
- "/etc/timezone:/etc/timezone:ro"
- "/etc/localtime:/etc/localtime:ro"
