Docker - Error

[onedr0p]

Hi,

I am trying to run glances with docker-compose. I am using your docker container.

Docker version: 1.12.6

docker-compose.yaml

version: "2"
services:
  glances:
    image: docker.io/nicolargo/glances
    container_name: glances
    ports:
      - "61208-61209:61208-61209"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      - GLANCES_OPT=-w
    pid: "host"

I get this errors in the console:

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

I get the same error when running:
docker run -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances

Thanks for all your help!

I also have this issue. This is caused by wifi library, see this issue.

My own fix is to create a Dockerfile and install wireless-tools package:

FROM nicolargo/glances

RUN apt-get update
RUN apt-get install -y wireless-tools

and edit docker-compose.yml to build using the Dockerfile:

version: "2"
services:
  glances:
    image: test-glances
    build:
      context: .
      dockerfile: Dockerfile
    container_name: glances
    ports:
      - "61208-61209:61208-61209"
    environment:
      - GLANCES_OPT=-w

For those using this from a headless server, add --disable-wifi to the GLANCES_OPT section

--disable-wifi did the trick thanks!

I just add the wireless-tools package inside the top level Dockerfile.

It should work out-of-the-box now...

Just wait on or two hours before testing (the Docker build process is long...).
