Note that the probe command is executed directly, not in a shell, but you are using a pipe. try this:
command: - sh - -ec - ps -ef | grep my_process_name aside from that - don't run multiple processes in a container; use multiple containers in a pod instead. Make sure that when your process exits, the main command does; the best way is to ensure that everything is exec'd instead of running as subprocesses. Then, you don't need this probe as the container runtime will know that your process is no longer running and will restart it automatically. /MR On Thu, Jun 1, 2017, 21:41 Rodrigo Campos <rodr...@sdfg.com.ar> wrote: > Did it worked? :) > > (note that both formats, Guangya Liu used and I, are valid in yaml for > arrays, > so both should be fine, choose the one you prefer). > > On Thu, Jun 01, 2017 at 07:42:07AM +0800, Guangya Liu wrote: > > Yes, should use array, here is an example: > > > > ``` > > > > livenessProbe: exec: > > command: > > - cat > > - /tmp/healthy > > > > ``` > > > > I think that you can probably run the case > > > https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/ > > here first and then update the template step by step to fit your case. > > > > On Thu, Jun 1, 2017 at 7:38 AM, Rodrigo Campos <rodrig...@gmail.com> > wrote: > > > > > You should use an array, like ["command", ... ], IIRC the syntax > correctly > > > > > > > > > On Wednesday, May 31, 2017, Sambit Mishra <sambitmishra...@gmail.com> > > > wrote: > > > > > >> I have a process running inside an Ubuntu container and would like to > > >> redeploy the container if the process gets killed.
