CentOS 7 docker prometheus volume error "open /prometheus/lock: permission denied"

[zhangjie2012]

I want mount /prometheus to host path /data/prometheus，so I create container like this:

docker run -it -d -p 9090:9090 --restart=always -v /data/prometheus:/prometheus -v /data/conf/prometheus.yml:/etc/prometheus/prometheus.yml docker.io/prom/prometheus

start failure, docker logs show :

...
 err="opening storage failed: lock DB directory: open /prometheus/lock: permission denied"

I had change host /data/prometheus dir owner and group to nobody:nobody.

You are probably hitting the issue because of SELinux. See https://stackoverflow.com/questions/24288616/permission-denied-on-accessing-host-directory-in-docker

I'm closing it for now. If you have further questions, please use our user mailing list, which you can also search.

I had fix it.

1. create a prometheus container , cat /etc/passwd => nobody:x:65534:65534:nobody:/home:/bin/false
2. host set /data/prometheus owner and group to 65534
