Error creating a template

[sonic arrow]

I am trying to create a template (-n9Md7 currently unpublished) based on this project (id: 462b54b8-a74e-4132-8c36-8530315ad71e) and faced a couple of issues:

• I expected that the variable bindings (DATABASE_PRIVATE_URL -> ${{Postgres.DATABASE_PRIVATE_URL}} and DATABASE_URL to ${{Postgres.DATABASE_URL}} to have been populated in the template. They weren't.
• I defined those bindings in the template manually. When I try to publish the template, I get "Missing variable details": "Please add description or default values for all variables".

Any ideas on fixing this?

when you create a template from a project the variable names are copied over, but not the variable values

instead of going through and setting those all up, fork the postgres template https://railway.app/button?code=postgres
then go back and edit it, change the template name, and then add your service to it

Thanks.

But how would I create bindings in my Exograph service to Postgres variables (binding by reference such as ${{Postgres.DATABASE_PRIVATE_URL}})?

[subtle elm]

you already did, heres a completed template https://railway.app/template/eMpJru
and heres the forkable link https://railway.app/button?code=eMpJru

ive just embedded your railway-template into it

Thanks. I need to grok Railway's templating system. When I tried to deploy using your template, I got a repo conflict error.

I want to create a repository such as https://github.com/exograph/railway-template with a "Deploy to Railway" button. When someone visiting that repo clicks the button, they fork it into one of their repo and deploy that to Railway. Is the way I am approaching the right way to go?

[subtle elm]

yes, that will clone the repo included in the template service into the users github account, but you cant have two repos with the same name so you are asked to change the name

I am not able to use this template to create a new project. I added the button for the template you provided to https://github.com/exograph/railway-template and tried a few ways.

Click "Deploy to Railway" and I get to the template page (as expected) and then either of the following:

• Click on "Deploy now". I get "Repo name collision".
• Click on "Config" for "railway-template" to specify a different repo name. I get "Ready to be deployed", but the "Deploy" button is disabled.

Click on "Deploy now". I get "Repo name collision".
yes, github doesnt allow you to have two repos with the same name

Click on "Config" for "railway-template" to specify a different repo name. I get "Ready to be deployed", but the "Deploy" button is disabled.
screenshots please

you need to configure postgres

configure > save config

[sonic arrow]

About the first, of course. However I imagined that the UI would prompt me to do a clone.

[subtle elm]

railway is not going to overwrite any existing repos

that would bring so many issues

[sonic arrow]

Success!

Thank you so much for your (as always) prompt and precise help.

[subtle elm]

of course!

However, I am unsure if I would go with the template approach. The main draw was a "One click deploy"

[subtle elm]

someone who doesnt have a repo with the same name wont get that error

[sonic arrow]

I see. I will try that.

[subtle elm]

you have the repo with the same name since you created the repo

[sonic arrow]

There was an additional issue. The initial deployment failed. I will investigate more, but it seemed like the Postgres service wasn't ready in time for the Exograph service to use it. I needed to redeploy the Exograph service to make it succeed. I kind of expected this since no service dependency is expressed in the template, but it may confuse a newcomer.

use nc in the start command to ping the database on a loop and exit when it can ping it

thank you for the trains!!
