Developer (Dev) URLs allow users to access the ports of services they are developing within their environment. However, before individual developers can set up Dev URLs, an administrator must configure and enable Dev URL usage.
You must own a wildcard DNS record for your custom domain name to enable and use Dev URLs with Coder.
Dev URLs is an opt-in feature. To enable Dev URLs in your cluster, you'll need to modify your:
devurls.host to a wildcard domain pointing to your ingress controller:
helm upgrade coder coder/coder --set devurls.host="*.my-custom-domain.io"
If you're using the default ingress controller, specifying a value for
devurls.host automatically adds a rule that routes Dev URL requests to the
- host: "*.my-custom-domain.io" http: paths: - path: / backend: serviceName: envproxy servicePort: 8080
If you are providing your own ingress controller, then you will need to add the rule manually.
The final step to enabling Dev URLs is to update your wildcard DNS record. Get
the ingress IP address using
kubectl --namespace coder get ingress and
point your wildcard DNS record (e.g., *.my-custom-domain.io) to the ingress IP
