smfc in docker

This is a docker image for smfc. Please visit the GitHub repository of smfc for more details or for reporting issues.

Content

This image contains the following components:

Some further notes:

  1. smfc will be executed as a simple foreground process here (not as a systemd service).
  2. Currently, the image does not require any networking, it is disabled.
  3. ipmitool and smartctl require read-only access to host's /dev/ and /run folders and admin privilege.
  4. The /sys filesystem can be accessed in the container, but the proper kernel module (i.e. coretemp, k10temp, or drivetemp) needs to be loaded on host side.
  5. The container can send log messages to the host's journald daemon (as it is configured in Usage chapter), but feel free to configure other logging drivers.
  6. /opt/smfc/hddtemp_emu.sh script is also available in docker.

Usage

docker CLI

The service can be started:

docker run \
  -d \
  --rm \
  --log-driver=journald \
  --privileged=true \
  --name "smfc" \
  -v /dev:/dev:ro \
  -v /run:/run:ro \
  -v /etc/timezone:/etc/timezone:ro
  -v /etc/localtime:/etc/localtime:ro
  -v /opt/smfc/smfc.conf:/opt/smfc/smfc.conf:ro \
  -e SMFC_ARGS="-l 3" \
  petersulyok/smfc

(sample script can be found here), and can be terminated:

docker stop smfc

docker-compose (recommended)

docker-compose requires this file:

version: "2"
services:
  smfc:
    image: petersulyok/smfc
    container_name: smfc
    network_mode: none
    logging:
        driver: journald
    privileged: true
    environment:
      - SMFC_ARGS=-l 3
    volumes:
      - /dev:/dev:ro
      - /run:/run:ro
      - /opt/smfc/smfc.conf:/opt/smfc/smfc.conf:ro
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
    restart: unless-stopped

(sample yaml file can be found here), and docker image can be started/stopped this way:

docker-compose up -d
docker-compose down
