Gitlab-ci-multi-runner and register.json


I’m pretty sure my problem is very simple to solve as I’m sure it’s just a path in the config.toml.

The error message I get in GitLabs Server production.log is

Started POST "/ci/api/v1/builds/register.json" for <ip> at 2018-04-04 09:18:40 +0200

ActionController::RoutingError (No route matches [POST] "/ci/api/v1/builds/register.json"):
  lib/gitlab/request_context.rb:18:in `call'
  lib/gitlab/metrics/requests_rack_middleware.rb:27:in `call'
  lib/gitlab/middleware/release_env.rb:10:in `call'

As far as I’ve learned from several issues on GitLabs project and other posts, the problem is this line in the runners section of config.toml:
url = "https://<my gitlabs domain>/ci

It was mentioned that the endpoint has changed, but my problem is that I can’t find any hint where to, as all example configs still point to that /ci location.

So, could anybody tell me what the correct url is?

The problem somehow resolved itself.
