5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
No problem. You should be able following this link (changing for your GL URL) https://<your_gitlab_url>/help/user/project/clusters/add_remove_clusters.md#existing-kubernetes-cluster 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 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.
Hey, Thanks for sharing. Any chance you have the Dockerfile or Docker image available to share with the community?
Hi Andy, You should treat the CentOS image as a virtual appliance that Nutanix provides to run the K8s clusters with Karbon. This CentOS image comes hardened OOTB (if you need the report of this hardening you can contact your Nutanix account team) To provide an example, this is like if you are running F5 virtual appliance that uses CentOS and you want to upgrade/patch that CentOS that F5 is providing you. You won't do it because it is a "closed" image. What we provide with the CentOS image is a managed service experience where customers don't need to worry about the image at all. I hope this makes sense to you. If you want, we can discuss further. I see you are also UK based, happy to have a catch up anytime if you want to. Regards, Jose
Hi, What's the reason of looking to upgrade the image? Regards, Jose
You need an user with Cluster Admin role at the Prism Element level. Depending from what PE cluster you will use for storage, you will need an user on it.
Hi Javier, You will need connectivity from the Karbon VLAN to the AOS, AHV and PC VLAN. Also, from the Karbon VLAN to the internet. A quick test is to connect to the only provisioned VM via SSH and try to pull an image from Docker Hub. You can try the following to make sure the VM has connectivity to the Internet. [code]sudo docker pull alpine [/code] When you get the prompt with the credentials for sudo, use the common Nutanix one. If after this it doesn't work, I'd suggest you open a ticket with our support. Regards, Jose Gomez
Hi Javier, Can you share the details for your deployment? Usually when it fails at 8% is because network problems with IP address allocations or internet connectivity. Regards, Jose
[quote=echolaughmk]Hi, How did you enable a username/password for credentials to hit the secure URL for the dashboard. From my testing with the dashboard, it always prompts for a kubeconfig file or token given it only has the concepts of service accounts - I am not able to get it to work to prompt me for a user/password. I didn't deploy Heapster, just the dashboard for the moment. Jut curious if there is something I might be missing. thanks! -Keith[/quote] This is due to changes on the latest version of Kubernetes Dashboard. On this latest version you will need to get the token running the following commands: [list=1] [*][b]kubectl -n kube-system get secret[/b] [*]Look for the kubernetes-dashboard-token [*][b]kubectl -n kube-system describe secret kubernetes-dashboard-token-[/b] [*]Copy the token and paste it in the K8s Dashboard website. [/list] Let me know if this works for you. -Jose Gomez
