---
version: "3.9"
services:
  alpine:
    image: imoize/alpine-s6:latest
    container_name: alpine
    environment:
      - PUID=1001
      - PGID=1001
      - TZ=Asia/Jakarta
    restart: always

• docker cli

docker run -d \
  --name=alpine \
  -e PUID=1001 \
  -e PGID=1001 \
  -e TZ=Asia/Jakarta \
  --restart always \
  imoize/alpine-s6:latest

Configuration

Environment variables

When you start the alpine-s6 image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. Please note that some variables are only considered when the container is started for the first time. If you want to add a new environment variable:

• for docker-compose add the variable name and value:

alpine-s6:
    ...
    environment:
    - PUID=1001
    ...

• for manual execution add a -e option with each variable and value:

  docker run -d \
  -e PUID=1001 \
  imoize/alpine-s6:latest

Available environment variables:

• PUID=... for UserID.
• PGID=... for GroupID.
• TZ=... specify a timezone see this list. Default: UTC
• S6_VERBOSITY=... controls the verbosity of s6-rc. Default: 1
  • 0 will only print errors.
  • 1 will only print warnings and errors.
  • 2 is normally verbose: it will list the service start and stop operations.

User / Group Identifiers

For example: PUID=1001 and PGID=1001, to find yours user id and gid type id <your_username> in terminal.

  $ id your_username
    uid=1001(user) gid=1001(group) groups=1001(group)
