I have a process running inside an Ubuntu container and would like to
redeploy the container if the process gets killed. I added the following
liveness probe in container spec
-livenessProbe:
exec:
command:
- ps -ef | grep my_process_name
initialDelaySeconds: 120
periodSeconds: 30
However this doesnt work. When I do a kubectl describe pods I get the
following event.
1h 6m 20 {kubelet k8s-agent-71e8d996-0} spec.containers{my_process_name}
Warning Unhealthy Liveness probe failed: rpc error: code = 13 desc =
invalid header field value "oci runtime error: exec failed:
container_linux.go:247: starting container process caused \"exec: \\"ps -ef
| grep my_process_name\\": executable file not found in $PATH\"\n"
And it keeps redeploying the container. If I bash into the container and do
a 'ps -ef' it works but this doesnt Whats a good way to use the liveness
probe to check if a process is running or not ?
