Hi Anibal,

I guess you are looking the GitLab CI/CD integration with Kubernetes. If that’s the case, you just need to follow the GitLab Admin Guide that explains how to setup an existing Kubernetes cluster in your GitLab instance.

Hi Jose,

Great to know, I want to do it today or at last tomorrow, let me cross the fingers and see ;-)

No problem.

You should be able following this link (changing for your GL URL) https://<your_gitlab_url>/help/user/project/clusters/

  • If you are running GitLab inside of your K8s cluster to configure, make sure you use the IP address of the Kubernetes service in the default namespace and not the FQDN kubernetes.default.svc.
  • If you are running GitLab out of the K8s cluster to configure, make sure in GitLab you allow the internal IP communication. Also, then you will need to use the IP address of the master.

Hi, now I have time to put the hands over the keyboard at start to implement the gitlab CI/CD integration with Karbon.

Following the gitlab kubernets integration document I stopped at token/gitlab-admin account.

I included the kubeconfig at my linux running inside my win10, I can reach the karbon showing the cluster info without any problem and also connected directly to the karbon with .sh scripts, but for both I can’t add the user and get:


kubectl apply -f gitlab-admin-service-account.yaml
serviceaccount/gitlab-admin unchanged unchanged


I supposed that this kind of access are like admin, but it’s not.

Exist any tip that I need to do to be abble to create this user?

Hi.. I hope that I used wrong, with the token access gitlab can reach the karbon cluster.. but I facing a problem to install Helm from gitlab.. I have a proxy between the server and the internet.. running kubectl from a linux machine I can deploy the kubernets dashboard without any problem, they download the images and deploy.. but the helm I see few problem to deploy.

At the PC and PE I changed the proxy settings to use one proxy over a linux machine to by pass my proxy authentication, normally works fine.. but on this case not:


m48s       Normal    Pulling     pod/install-helm   Pulling image ""
3m48s       Warning   Failed      pod/install-helm   Failed to pull image "": rpc error: code = Unknown desc = Error response from daemon: Get Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied.  )
3m48s       Warning   Failed      pod/install-helm   Error: ErrImagePull


my doubt, after I changed the proxy at PC and PE I need to do any proxy refresh at Kabon? Exist a way to check the proxy that Karbon are using to get internet access?

For my undestading the kubernetes-charts are tried to be installed without trought the proxy, true we didn’t see any proxy access to reach this site.

Exist a way to validate the internet access for the pods under the karbon?
