- **CA certificate** (required) - A valid Kubernetes certificate is needed to authenticate to the EKS cluster. We will use the certificate created by default.
- List the secrets with `kubectl get secrets`, and one should named similar to
`default-token-xxxxx`. Copy that token name for use below.
- Get the certificate by running this command:
```sh
kubectl get secret <secret name> -o jsonpath="{['data']['ca\.crt']}" | base64 --decode
```
- **Token** -
GitLab authenticates against Kubernetes using service tokens, which are
scoped to a particular `namespace`.
**The token used should belong to a service account with
- **GitLab-managed cluster** - Leave this checked if you want GitLab to manage namespaces and service accounts for this cluster. See the [Managed clusters section](#gitlab-managed-clusters) for more information.
- **Project namespace** (optional) - You don't have to fill it in; by leaving
it blank, GitLab will create one for you. Also:
- Each project should have a unique namespace.
- The project namespace is not necessarily the namespace of the secret, if
you're using a secret with broader permissions, like the secret from `default`.
- You should **not** use `default` as the project namespace.
- If you or someone created a secret specifically for the project, usually
with limited permissions, the secret's namespace and project namespace may
be the same.
-**Kubernetes cluster name** (required) - The name you wish to give the cluster.
-**Environment scope** (required) - The
[associated environment](#setting-the-environment-scope-premium) to this cluster.
-**API URL** (required) -
It's the URL that GitLab uses to access the Kubernetes API. Kubernetes
exposes several APIs, we want the "base" URL that is common to all of them,
e.g., `https://kubernetes.example.com` rather than `https://kubernetes.example.com/api/v1`.
