Create an empty directory and cd into it.

Add the branch or tag of the kubespray repository you want to use.

echo release-2.11 > kubespray.version

Add a kubespray-based hosts.ini file and adjust to your liking ( take it from kubespray/inventory/sample/hosts.ini for example.

Create group_vars directory, only add the files you want to override from the official kubespray group_vars, and only add the variables you want to change:

mkdir -p group_vars/all
echo "loadbalancer_apiserver_localhost: true" > group_vars/all/all.yml

docker run -it --rm -v pwd:/app -w /app verwilst/kubespray-runner:latest kubespray-runner.sh cluster.yml

Add "-v ~/.ssh:/root/.ssh" to make sure your SSH keys work.
