Cant see user name when run netdata in docker

[luanmingyi]

Question summary

I run netdata in docker, the user names in the "per user statistics" under Users tag are not shown, instead it shows the user id (except for root netdate xfs). I want see the user name in the legand.

It looks like the problem is about docker not netdata, but i search it on google and fail to solve it.

below is my docker-composer file:

version: "3"
services:
  netdata:
    image: netdata/netdata
    ports:
      - 19999:19999
    cap_add:
      - SYS_PTRACE
    environment:
      - PGID=999
    security_opt:
      - apparmor:unconfined
    volumes:
      - /proc:/host/proc:ro
      - /sys:/host/sys:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    restart: always

OS / Environment

ubuntu 18.04
docker 18.09.3

@vlvkobal any suggestions on this one?

We use getpwuid() call to get user names that's why the information is retrieved from /etc/passwd inside the docker container. To do this the right way we need to read the file itself and mount the host's file to the container under /host/etc/passwd.

volumes:

• /proc:/host/proc:ro
• /sys:/host/sys:ro
• /etc:/host/etc:ro
• /var/run/docker.sock:/var/run/docker.sock:ro

I modify the docker-composer file as above, but does not work.

getpwuid() knows nothing about /host/etc/passwd. So, we need to modify apps.plugin to make it read the correct information.

Any news on this issue ? I too would like see user name instead of ID.
