hey. i've been going through the docs on this but couldn't find a clear answer for a non-node, shared monorepo, whose all services are defined in dockerfiles.

project/
├── apps/
│   ├── service1/
│   │   ├── data/
│   │   └── tests/
│   └── service2/
│       ├── data/
│       ├── notebooks/

│   └── service2/
├── packages/

│   ├── types/
│   └── utils/
├── scripts/
└── tests/

here's some directories in my repo. in apps i have all my shared services, and their dockerfiles are in /docker. the services are serverless python functions that i plan to run with cronjob and app sleep in railway.

goal

i want to deploy each service via dockerfile as defined in /docker/, which uses code from the whole repo. whenever changes are made to a service's dockerfile, to deploy to railway.

guess

i've read in this forum that railway.json are scoped to 1 service. so maybe inside of /docker/service[x]/, along with my Dockerfile have a railway.json that specifies watch files? making this path the root dir of service?

I think you may want to set the dockerfile location with an env var?

you would of course not set a root directory and deploy multiple services for the multiple apps you want to deploy

yes that works

does that also mean you were able to get your project stood up?

yes. but i did it all on the gui. i have a config-as-code followup.
for the solution u gave me, that's just this part of the railway.json, yes?

{
  "$schema": "https://railway.com/railway.schema.json",
  "build": {
    "dockerfilePath": "Dockerfile.backend"
  }
}

i think i've seen an input in service settings where i can specify the location of the railway config file, if i wanted to interact with gui i'd just put the path there and the rest can be defined in the json? and i'd need a different railway.json file per service? would i just put that in the corresponding /docker/service[x]/ dir alongside the Dockerfile?

can you share why you want to go to the config file route given you are only needing to set a single setting, vs setting a service variable per my recommendation, your method is far more involved

i would've liked to have all of these things defined in my repo. i also didn't mind learning about it.

hmmm but you can't define the railway.json path in your repo so it's kinda the same problem, just now you have an extra unneeded file

yes. i suppose going all the way is more effort than i'd like. this will do for now then! thanks.
