Install MinIO in a Kubernetes cluster and use it as cache storage for your GitLab CI Runner. We’ll use Helm 3 to install both.

As mentioned in my article about setting up GitLab CI with MinIO using Helm 2, the default, one click installation from the GitLab admin panel is absolutely simple and works fine as long as you have no special requirement.
