Hey Gautam,

Going to need more info so that I can give you an appropriate answer -

In my current workflow I deploy the app on railway as a project

Do you mean you deploy a template from the CLI?

Additionally, Would you mind if I made this thread public as I'm not seeing any sensitive information and the topic being discussed could be helpful to other users.

Hi Brody,

I deploy the app from the command line like this:

railway init -n <app-name>
railway up -c
railway domain
railway link ...
railway volume add -m /app/data 

Hope that answers your question(?)

Sure, you can make this public.

Yes it does, Does this Project also exist in GitHub? If so you could make a whole template from it, it would be much faster to deploy from the CLI that way and you can pass in environment variables.

Thanks Brody.

Yes it does exist on Github. Ok, I will follow the template route. Could you point me to the docs that might help me? I found this: https://docs.railway.app/guides/create

Thats exactly what I would have linked! you are on the correct path.

Let ne know if you need any help with the template.

I have the same exact question as it happens. I'd rather not convert to a template, since I use CLI to deploy all my projects. So I'm looking for a way to set variables from the CLI.

That is not something the CLI supports right now, but we would be happy to accept a PR that adds that functionality.

Got it. Could you outline the general approach needed for such a PR? Is there something in the graphql API already that would support this?

Yes the public API does support this -

https://docs.railway.app/reference/public-api

https://railway.app/graphiql

As for the PR, implement the feature and make a PR, nothing much to that.

I gave up on the template route too since I want to stick to using the CLI.

I doubt I'll manage to make a PR because I don't know Rust.

I guess this guide is relevant: https://docs.railway.app/guides/manage-variables

Yep you would have to use the API if using a template / dashboard is out of the question for you.

Ok, Claude helped me get this working. This is what works for fetching the variables:

curl --request POST \

--url https://backboard.railway.app/graphql/v2 \

--header 'Authorization: Bearer <API_TOKEN_GOES_HERE>' \

--header 'Content-Type: application/json' \

--data '{

"query": "query variables($projectId: String!, $environmentId: String!) { variables(projectId: $projectId, environmentId: $environmentId) }",

"variables": {

"projectId": "8df3b1d6-2317-4400-b267-56c4a42eed06",

"environmentId": "9fb4baf0-809a-40ec-af32-751f50890802"

}

}'

Sorry that it's so inconvenient to copy-paste but for the life of me I couldn't figure out how to format that!!!

Triple backticks followed by the language (bash) and then press enter.

curl -I "https://www.google.com"

Ok, and this is how you can set a variable (without serviceID):

curl --request POST \
  --url https://backboard.railway.app/graphql/v2 \
  --header 'Authorization: Bearer <API_TOKEN>' \
  --header 'Content-Type: application/json' \
  --data '{
    "query": "mutation variableUpsert { variableUpsert(input: { projectId: \"8df3b1d6-2317-4400-b267-56c4a42eed06\", environmentId: \"9fb4baf0-809a-40ec-af32-751f50890802\", name: \"NEW_VARIABLE\", value: \"SECRET_VALUE\" }) }"}'

Hope this helps everyone trying to do it with the CLI.

Thanks for this! I think it's good to mark as solved now!
