I don't think the error message could be any clearer. You told it to read the file /prometheus.yml, but /prometheus.yml is a directory, not a file.
The most likely reason is here: https://stackoverflow.com/a/44950494/14241561 Namely, the file didn't exist on the host at the time you mounted it with -v, so it got created as a directory instead. Note that volume-mounting a single file like this is unwise anyway, in the case that you might want to change this file while the container is running: https://forums.docker.com/t/sharing-a-single-file-via-a-volume-mount-does-not-work-as-expected/57088 It's better to mount the enclosing directory. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
