Postgres Migration Problem

Hey Folks, I'm trying setting up the self hosted version of your very promising tool but run in some problems: 1. Do you have a Docker Image made for ARM Architecture? Or have it planned to do so? (WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested 2. When I try to set up the docker, the database migration fails with: Prisma schema loaded from prisma/schema.prisma Datasource "db": PostgreSQL database "postgres", schema "public" at "localhost:5432" Applying database migrations failed. Exiting... Are there more requierements for the postgres DB (do I have to create a database I'm not aware of or anything?)? I'm super curious to implement your tool in my project! Please help me do so 🙂

Ps. I'm running this docker command: docker run --name langfuse \ -e DATABASE_URL=postgresql://postgres:XXXX@localhost:5432 \ -e NEXTAUTH_URL=http://localhost:3000 \ -e NEXTAUTH_SECRET=XXXX= \ -e SALT=mysalt \ -p 3000:3000 \ -a STDOUT and the database url is verified by running it with psql "postgresql://postgres:xxxx@localhost:5432" -> postgres=#

Pps. Now I tried to build the container myself as described in https://langfuse.com/docs/deployment/local Set Up works buitiful but then the Log In Page appears. Not very suprisingly, my langfuse credentials don't work (since I'm running it local), I guess the password would be the one I set in the docker_compose as NEXTAUTH_SECRET= XXXX But which user does the password belong to

Thanks for just booking 15 min, let’s debug together and fix the docs accordingly!

Hey I found a solution! The problem was, that the database could'nt be seen by the container. I needed to replace the 'localhost' with docker.host.internal in my database connection string.

docker run --name langfuse \
-e DATABASE_URL=postgresql://USER:PW@host.docker.internal:5432 \
-e NEXTAUTH_URL=http://localhost:3000 \
-e NEXTAUTH_SECRET=mysecret \
-e SALT=mysalt \
-p 3000:3000 \
-a STDOUT \
ghcr.io/langfuse/langfuse:latest

docker run --name langfuse \
-e DATABASE_URL=postgresql://USER:PW@host.docker.internal:5432 \
-e NEXTAUTH_URL=http://localhost:3000 \
-e NEXTAUTH_SECRET=mysecret \
-e SALT=mysalt \
-p 3000:3000 \
-a STDOUT \
ghcr.io/langfuse/langfuse:latest

Happy to hear that

@Marc is there a docker image for linux/arm64 ?

Marc•10mo ago

Not yet. There is an open issue tracking this. What’s your use case for it?

kranthi•10mo ago

I'm using aws cloud and graviton instances for application which requires arm64 architecture image.

Marc•10mo ago

Understood Is there a reason why you want to use graviton instances to run the langfuse container?

kranthi•10mo ago

Not specific to langfuse but in general graviton instances are cheaper compared to non-graviton instances.

Marc•10mo ago

Yep agree, happy to support a PR on this, this is tracked here: https://github.com/langfuse/langfuse/issues/452

Hi, I've been having the same issue for a while, solved with solution you've suggested. Just wanted emphasize for others as a reference.

Marc•6mo ago

Thanks for sharing, the docker compose file is probably a good reference for this setup as it also includes docker internal networking
