Need clarification on pictrs update to 0.5 for 19.4 - Docker Compose (lemux.minnix.dev)

Anyone care to share their docker compose file for the upgrade? Or at least the pictrs portion? I've upgraded and migrated postgres to 16, but am having issues with the pictrs part.

Set image tag in pictrs section to 0.5 and change to the new ENV format described in the docs of pictrs. At last start only the pictrs container docker compose up -d pictrs

Here is my example in the new formaz. Be aware it is just an example ☝🏻


pictrs:
    image: asonix/pictrs:0.5
    container_name: lemmy-pictrs
    # this needs to match the pictrs url in lemmy.hjson
    hostname: pictrs
    # we can set options to pictrs like this, here we set max. image size and forced format for conversion
    # entrypoint: /sbin/tini -- /usr/local/bin/pict-rs -p /mnt -m 4 --image-format webp
    environment:
      - PICTRS_OPENTELEMETRY_URL=http://otel:4137
      - PICTRS__SERVER__API_KEY=redacted
      - RUST_LOG=info
      - RUST_BACKTRACE=full
      - PICTRS__MEDIA__VIDEO__VIDEO_CODEC=vp9
      - PICTRS__MEDIA__ANIMATION__MAX_WIDTH=256

      - PICTRS__MEDIA__ANIMATION__MAX_AREA=65536

This is the part of the new compose file that I don't understand:

PICTRS__OLD_REPO__PATH=/mnt/sled-repo PICTRS__REPO__TYPE=postgres PICTRS__REPO__URL=postgres://user:password@host:5432/db

When I try to add it, pictrs complains about not being able to connect to postgres, even though the credentials are correct and I've already run the postgres migration script. Did you not do this part when you upgraded?

[–] morethanevil@lemmy.fedifriends.social 1 points 4 months ago

No I just replaced the image tag. Pictrs will do the upgrade itself.

This is for making the pictrs backend on postgres and to migrate it to postgres. Though not documented with Lemmy it works and I am running it that way on my instance. It allows you to load balance and have high availability of pictrs service.
