<p>After deploying, it will generate several ingresses, but <strong>we cannot access them by using external machine</strong>.

<p>So I try to forward them by</p>
<pre><code>kubectl port-forward --namespace default svc/gitlab-webservice-default 9000:8080 --address 0.0.0.0
kubectl port-forward --namespace default svc/gitlab-webservice-default 9001:8081 --address 0.0.0.0
</code></pre>
<p>8080 are from <code>ingress/gitlab-webservice-default</code>.  <strong>9001</strong> cannot be access, It means I cannot access https</p>
<pre><code>  rules:
    - host: gitlab.192.168.49.2.nip.io

<p>But it seems not work when I try to login.</p>

<p>This issue is poorly documented via gitlab itself and the below 'answer' is for any googlers (hint, it's not really an answer):</p>
<p>The gitlab minikube setup spins up it's own ingress controllers that are bypassed, which is where TLS would normally be terminated. The '422' error is legitimate because <code>localhost:8080</code> does not provide a valid authenticity token to be processed by the host <code>gitlab.192.168.49.2.nip.io</code></p>
<p>You can confirm this by tailing the logs of the webserver container (it outputs all logging to stdout).</p>
<p>So you can either disable to CSRF token check in the <code>omniauth.rb</code> file inside <code>config/initializers</code> and restart the rails instance, or move away from minikube (we used KinD to get this working) since ingress appeared to be broken with the gitlab setup.</p>
