DNS: Verification

For some project with at least one devcontainer service and the proxy enabled:

{
  ...,
  "customizations": {
    "devconcurrent": {
      "proxy": {
        "enable": true,
        }
      }
    }
  }
}

Run dc up. This will start the workspace containers as well as the DNS server.

Run dc proxy status; you should see green checks for DNS and RESOLV for your service(s). If DNS is red, then there’s something wrong with devconcurrent, and if RESOLV is red, then devconcurrent is not getting traffic from your OS.

If your services are listening on any ports, you should be able to reach them on those ports using the hostname; for an http service at setup.app.test that listens on port 3000, curl setup.app.test:3000 should work.
