Adding kubernetes cluster to GitLab - getting the CA certificate
I'm attempting to add a Digital Ocean Kubernetes cluster to GitLab. It asks for these values:
- Kubernetes cluster name
- API URL
- CA Certificate
- Project namespace (optional, unique)
I followed the answers in a previous post (https://www.digitalocean.com/community/questions/adding-kubernetes-cluster-to-our-private-gitlab-server), and I solved everything except "CA Certificate."
Looking at the cluster's config.yml file (downloaded from Digital Ocean), I see a few values including CERTIFICATE-AUTHORITY-DATA, CLIENT-KEY-DATA, etc. However, these don't seem to be PEM format - which I assume is necessary.
In the end, I tried a few different values. GitLab continues with the setup without complaint, but the installation of Helm Tiller fails every time. This tells me that GitLab doesn't confirm the values.
Can anyone tell me how to find my CA Certificate? Thanks.
