Back up this pack

This pack stores data in one Docker named volume: remark42_data

restic

# Run on the node hosting this pack. Point restic at your repo first:
#   export RESTIC_REPOSITORY="s3:https://<account>.r2.cloudflarestorage.com/<bucket>"
#   export RESTIC_PASSWORD="<repo-password>"
#   export AWS_ACCESS_KEY_ID=<key>  AWS_SECRET_ACCESS_KEY=<secret>
restic backup \
  /var/lib/docker/volumes/remark42_data/_data

rclone (sync to S3/R2)

rclone sync /var/lib/docker/volumes/remark42_data/_data backup:<bucket>/remark42_data

Paths assume the default Docker volume location (/var/lib/docker/volumes). Restore by stopping the job, restoring files into the same volume, and re-running the pack.

Readme

remark42

Remark42 is a lightweight, privacy-focused commenting engine you can embed on any website or blog — a self-hosted alternative to Disqus. It supports anonymous and social logins (GitHub, Google, Twitter, Microsoft, Apple and more), threaded discussions, voting, moderation, email notifications, image uploads and import/export. It's tiny: typically well under 100 MB of RAM.

This pack runs Remark42 as a single host-networked Nomad service backed by its embedded BoltDB store.

Deploy

nomad-pack run remark42 --registry=nomploy \
  --var remark_url=https://comments.example.com \
  --var secret=$(openssl rand -hex 24)

Then embed the widget on your pages (see the Remark42 docs for the script snippet), pointing host at this instance and site_id at your site.
