How to update/migrate from old docker-compose.yml to compose.yml?

[Rintan]

New compose file introduced in #160 . It seems to be essential to upgrade 4.8 or newer. Are there any upgrade guide?

Any updates on this?

Did you ever find this out @Rintan ?

I've tried to use a bitnami mongo image, but it seems to be difficult due to different database structure. So, I've migrated the database and modified compose.yaml to be compatible with the older db structure.

#volumes:
#  mongodb_data: { driver: local }

services:
  rocketchat:
    image: rocketchat/rocket.chat:${RELEASE:-latest}
    restart: unless-stopped
    labels:
      traefik.enable: "false"
      #traefik.http.routers.rocketchat.rule: Host(`${DOMAIN:-}`)
      #traefik.http.routers.rocketchat.tls: "true"
      #traefik.http.routers.rocketchat.entrypoints: https

Thanks @Rintan . I ended up figuring this out myself; the database was already using WiredTiger and Compose V2 worked with the compose file I had already; no changes needed. I'm still using the older MongoDB image instead of the Bitnami one too. Hopefully this is able to help someone else out, though.
