I am attempting to deploy Langflow on Railway using a Dockerfile from my GitHub repository, but the service crashes at runtime with filesystem permission and port parsing errors.
Repository:
https://github.com/jeremy-edwards2021/langflow
Docker directory:
https://github.com/jeremy-edwards2021/langflow/tree/main/docker
Dockerfile used:/docker/render.Dockerfile
The service builds successfully but crashes on startup.
I’d appreciate Railway’s help diagnosing this and advising exact changes (Dockerfile, start command, volume config, or Railway settings) so this can run correctly.

railway crashes because it uses a dynamic port and a read-only filesystem. to fix it, add a volume in railway settings with the mount path /data and use this start command:
langflow run --host 0.0.0.0 --port $port --database-url sqlite:////data/langflow.db
this forces the app to the correct port and moves the database to a writable location. don't use brackets in the dockerfile cmd or the port variable won't load.

I am not sure where to go exactly - there is not a option to add volume

Hey, first of all, make sure that you've a volume attached to your service mounted at /app/data . If you don't know what a volume is, please check here: https://docs.railway.com/overview/the-basics#volumes.
Also, there's already a Langflow template that could be used: https://railway.com/deploy/JMXEWp. If that one in specific doesn't suite you, please check others at https://railway.com/templates
