Problem Statement

resource "coder_app" "code-server" {
  agent_id = coder_agent.main.id
  url      = "http://localhost:8080/?folder=/home/coder"
  icon     = "/icon/code.svg"
}

And then is accessed at a URL like https://dev.coder.com/@ammario/moria/apps/code-server.

While many web applications can be configured to serve at specific paths instead of root, it's not always obvious, possible, or convenient.

In these cases, an organization may prefer setting up a wildcard domain so their users can use apps at /. We should add this setting in coderd since it would likely be configured alongside the main access URL. A coder admin could set it to cdr.app and then requests for {agent_id}-{app_name}.cdr.app could forward to a particular app.

Definition of done

Users can access coder_app via a subdomain instead of a path

example schema:

resource "coder_app" "code-server" {
  agent_id = coder_agent.main.id
  url      = "http://localhost:8080/?folder=/home/coder"
  icon     = "/icon/code.svg"
+ relative = true
}

- # url is https://coder.example.com/@workspace/app
+ # url is https://workspace-app.coder.example.com/
