How do I trigger a deployment to a railway service via github actions using ghcr.io built container image

I am trying to deploy a project that used to be connected to github directly as a container image deployment, but there is no way for me to programmatically trigger a deploy from my GH CI environment using the pre-built image my CI is creating using the same :latest tag. (I need GH to build it because the --ssh flag is not supported by railway)

I am trying to do so via the railway cli app in my CI, does not seem to be a way to do so

seems like railway redeploy -y does the trick maybe

Nope. cannot execute railway link without railway login, cannot execute railway login in non-interctive terminal

Can you try to set a project token environment variable in your action?

here is my github action job that does the deployment (on main branch, after my docker job has built and deployed the private image to ghcr.io):

env:
  REGISTRY: ghcr.io
  RAILWAY_ENVIRONMENT: staging
  RAILWAY_PROJECT_ID: <project-id>
  RAILWAY_SERVICE_ID: <service-id>
...
jobs:
  ...  # build job + others

  deploy-app:
    needs: [build-app, functional-test, fuzz-test, migrations-test]
    if: github.event_name != 'pull_request'
    runs-on: ubuntu-latest
    container: ghcr.io/railwayapp/cli:latest
    steps:
      - run: |
          railway login # <-- I added this because `railway link` yells about not being logged in
          railway link \
            --project ${{ env.RAILWAY_PROJECT_ID }} \
            --service ${{ env.RAILWAY_SERVICE_ID }} \
            --environment ${{ env.RAILWAY_ENVIRONMENT }}
          railway redeploy -y  # Trigger last deployment, which is using :latest tag anyways
        env:
          RAILWAY_TOKEN: ${{ secrets.RAILWAY_TOKEN_STAGING }}

At first, I didn't have railway login in there, and I got this:

Run railway link \
Unauthorized. Please login with `railway login`
Error: Process completed with exit code 1.

Then I added it:

Run railway login
  railway login
  railway link \
    --project <project-id> \
    --service <service-id> \
    --environment staging
  railway redeploy -y  # Trigger last deployment, which is using :latest tag anyways
  shell: sh -e {0}
  env:
    REGISTRY: ghcr.io
    RAILWAY_ENVIRONMENT: staging
    RAILWAY_PROJECT_ID: ***
    RAILWAY_SERVICE_ID: ***
    RAILWAY_TOKEN: ***
Cannot login in non-interactive mode
Error: Process completed with exit code 1.

You shouldn't need to run railway login in a GH action, that is what the token is designed to be used for.

Can you please have a look at the link I sent above?

If you notice in my example snippet, RAILWAY_TOKEN is in env when the command is run, I only put railway login because railway link didn't work

My apologies, I had overlooked that because I saw that you were still using railway login

Now that you have a token set, remove the login and link commands, and call redeploy with a --service flag.

Okay, thank you that worked. I think I had tried that without the --service flag at some point and it didn't work, and didn't match the local CLI experience (which had led me down the path of using railway link)

Glad you got it working, and sorry again for the confusion!
