Hey,

I am trying to setup deployments for specific PRs (based on triggers like comments or tags on GH).

I am aware that you can enable PR environments on Railway but I don't want every PR to be deployed since most don't need a deployment.

I have an existing build process (build + publish Docker images to GHCR) which builds multiple different images (I have 1 web image and 7 workers).

Is it possible to use my existing build process and deploy to Railway? I've read the docs about deploying a project from a Docker image but this doesn't seem to allow me to deploy branch specific Docker images from my GH workflow (via the CLI). In other words doesn't seem like I can change which image is being deployed using the CLI.

Even if I were to migrate my build process to be natively on Railway I don't see a way to update the image to deploy for each service (different in each environment) via the CLI

My end goal is essentially the following:

1. PR is opened

2. IC comments /deploy

3. GH workflow builds and publishes images for that branch/commit

4. GH workflow triggers deployment of those images on Railway

The docs I've read:

• https://docs.railway.com/guides/monorepo

• https://docs.railway.com/guides/dockerfiles

• https://docs.railway.com/reference/dockerfiles

• https://docs.railway.com/reference/config-as-code#configurable-settings

• https://docs.railway.com/guides/cli#environments

• https://blog.railway.com/p/github-actions

I feel like this should be straightforward so maybe I missing something.

There is currently nothing in here since I'm just trying to get up and running.

Thanks in advance for any help!
