Using the installer is the recommended way of installing Kubermatic Kubernetes Platform (KKP) into your cluster. It provides a simple web wizard for configuration and automates the installation of all required components.
At the moment you need to be invited to get access to KKP’s Docker registry before you can try it out. Please contact sales to receive your credentials.
The installer is available via Docker and can be run by
docker run --rm -p 8080:8080 quay.io/kubermatic/installer wizard
and then opening localhost:8080 in your browser. Follow the steps and you should be up and running in no time.
Because the installer runs inside a Docker container, it cannot access any cluster authentication providers on your host machine, like Amazon’s
aws-iam-authenticator. Make sure to provide static credentials in your
kubeconfig or use the
kubeconfig-serviceaccounts.sh script to automatically add static accounts to your clusters (see credentials section below).
If you feel more comfortable with using Helm, you can also use the installer to only create the
values.yaml for you and the continue to use Helm for the actual installation.
In any case, make sure to download the installer manifest and the
values.yaml when you’re done, so you can easily restart the installer at a later point to upgrade KKP.
Because the Docker image cannot access your local development toolset, you need to provide static credentials in your
kubeconfig to the installer. The recommended approach is to create a service account in your cluster that has
cluster-admin permissions and then use this account’s token for authentication.
To aid in this process, the installer repository contains a
kubeconfig-serviceaccounts.sh script that will automate the process. Create a copy of your
~/.kube/config and then call the script like so:
The script will update the file in-place. Afterwards you can copy&paste the file into the installer.
Your cluster needs to have a storage class
kubermatic-fast defined. The installer can automatically create a class that is backed by SSD storage with the provider’s default settings, but in case you need further customizations, create it before running the installer.
Please note the following limitations in the current installer:
kubeconfigneeds to contain exactly one cluster and context.
kubermatic-faststorage class already existing or run on GKE, EKS or ASK.
We are working on removing these limitations in the future.
