Command-Line Interface parameters

Required parameters

Most of the parameters have sane defaults and don't require customization. There are only a few parameters the user has to define:

  1. SECRET - secret key, can be any long and hard-to-guess string
  2. REMARK_URL - URL pointing to your Remark42 server, i.e.,
  3. At least one pair of AUTH_<PROVIDER>_CID and AUTH_<PROVIDER>_CSEC defining OAuth2 provider(s)

The minimal docker-compose.yml has to include all required parameters:

version: '2'

image: umputun/remark42:latest
restart: always
container_name: "remark42"
- REMARK_URL= # URL pointing to your Remark42 server
- SITE=YOUR_SITE_ID # site ID, same as used for `site_id`, see "Setup on your website"
- SECRET=abcd-123456-xyz-$%^& # secret key
- AUTH_ANON=true # enable anonymous commenting
- AUTH_GITHUB_CID=12345667890 # OAuth2 client ID
- AUTH_GITHUB_CSEC=abcdefg12345678 # OAuth2 client secret
- ./var:/srv/var # persistent volume to store all Remark42 data

Deprecated parameters

The following list of command-line options is deprecated and might be removed in the next major release after the version they were deprecated. After the Remark42 version update, please check the startup log once for deprecation warning messages to avoid trouble with unrecognized command-line options in the future.

Admin users

Admins/moderators should be defined in docker-compose.yml as a list of user IDs or passed in the command line.

- ADMIN_SHARED_ID=github_ef0f706a79cc24b17bbbb374cd234a691a034128,github_dae9983158e9e5e127ef2b87a411ef13c891e9e5

To get a user ID just log in and click on your username or any other user you want to promote to admins. It will expand login info and show the full user ID.

Docker image

Two parameters allow customizing the Docker container on the system level:

  • APP_UID - sets UID to run Remark42 application in container (default=1001)
  • TIME_ZONE - sets time zone of Remark42 container, would be used only on the backend as comments shown with user's timezone in the web interface (default=America/Chicago)

See umputun/baseimage for more details.
