Introduced in GitLab 11.11.
Similar to project-level and group-level Kubernetes clusters, instance-level Kubernetes clusters allow you to connect a Kubernetes cluster to the GitLab instance, which enables you to use the same cluster across multiple projects.
GitLab will try to match clusters in the following order:
- Project-level clusters.
- Group-level clusters.
- Instance-level clusters.
To be selected, the cluster must be enabled and match the environment selector.
For a consolidated view of which CI environments are deployed to the Kubernetes cluster, see the documentation for cluster environments.
For information on integrating GitLab and Kubernetes, see Kubernetes clusters.
