Create/manage Kubernetes cluster on GKE for GitLab group
Description
Thinking about how we could more deeply integrate Kubernetes/GKE into GitLab. We could move the Kubernetes service from a project-level setting, to a group-level first-class setting and make it easy to create and manage a Kubernetes cluster.
Proposal
- When no Kubernetes cluster configured, offer a button/form/dialog to create a cluster on GKE with specified number of nodes
- When configured, offer simple slider to scale up/down cluster
- Show link to Kubernetes dashboard (magically handling auth/proxying)
- Automatically create subdomain such as <group>.gitlab-apps.com(https://gitlab.com/gitlab-org/gitlab-ce/issues/38369)
- Automatically create static IP and Let's Encrypt for *.<group>.gitlab-apps.com(https://gitlab.com/gitlab-org/gitlab-ce/issues/38369)
- Install, enable autoscaling runner
- Install Prometheus
- Install NGINX-ingress
- For now, assume a single cluster for an entire group
