Hi Everybody, I’m not sure if this is a Kubernetes standard behavior or Podman bug/feature. When I: ================================================== tee test-this.yml <<< 'apiVersion: v1 kind: Pod metadata: name: mypod123 spec: hostname: test456 containers: - name: first image: docker.io/library/debian:bookworm command: ["/bin/sleep"] args: - "infinity" - name: second image: docker.io/library/debian:bullseye command: ["/bin/sleep"] args: - "infinity" - name: third image: docker.io/library/ubuntu:focal command: ["/bin/sleep"] args: - "infinity"' podman play kube test-this.yml ================================================== and then: ================================================== podman exec mypod123-first cat /etc/hostname test456 podman exec mypod123-first hostname mypod123 ================================================== And when I "podman exec -it mypod123-first bash" I can see "root@mypod123" in the prompt. In other words "spec.hostname" does change "/etc/hostname" but does not apply it like reboot on host would do. Can anyone please tell me, is it a bug or feature? Thank you. Kind regards, Rudolf Vesely
