Hey there! We've found the following might help you get unblocked faster:

• 🧵 Is it possible to run docker compose as a railway service
• 🧵 handling db migrations
• 📚 Build from a Dockerfile

If you find the answer from one of these, please let us know by solving the thread!

Yes railway does support docker compose files. I just attempted to deploy the redpanda for this bounty, the problem you are facing is "multiple volumes are not supported for a single service".

I checked the Dockerfile and in almost all services there is an attempt to mount a custom file to the container which railway treats as if they are volumes so it creates volumes by those names. Here in this instance "./bootstrap.yml" is being used by 3 services so first creates a volume by name "./bootstrap.yml" then throws errors because a volume cannot be mounted to multiple services.

./bootstrap.yml:/etc/redpanda/.bootstrap.yaml
./config:/tmp/config/
./transactions-schema.json:/etc/redpanda/transactions-schema.json
./transform/regex.wasm:/etc/redpanda/regex.wasm

Railway doesn't support volume mounts for config files so you will have to create custom Dockerfile that mounts these config files at build time

A simplistic example of Dockerfile for one of the service redpanda-console would look something like this.

FROM docker.redpanda.com/redpandadata/console:v3.1.3

COPY console-config.yam /tmp/config.yml

ENV CONFIG_FILEPATH=/tmp/config.yml

CMD ["/bin/sh", "-c", "echo \"$CONSOLE_CONFIG_FILE\" > /tmp/config.yml; /app/console"]

I am also looking to run a single node Redpanada, but I am getting the below error:

I have attached the docker compose that I am using.
