This repository will be used for hosting the script. It is used to generate couple of secrets and populate the installation files.

Run the following command to launch the script without cloning the repository:

wget -O - https://raw.githubusercontent.com/kubermatic-labs/k8c-install-webinar/master/generate.sh | bash /dev/stdin -k ./kubeconfig -d kubermatic.test.com

In the installation files we need to specify values and options that are required to successfully install Kubermatic. Those can be set manually or we can use this script to make it more user friendly.

Make the script executable:

chmod u+x generate.sh

Three mandatory flags needs to be set:

• folder: where the Kubermatic tarball has been extracted
• kubeconfig: Path to the kubeconfig file of the Seed cluster
• kubermatic-domain: Domain used to access Kubermatic

One optional flag, that is set by default to false:

• letsencrypt-prod: boolean saying which if a well-known certificate authority will be signing the certificates.

We can now run the script:

./generate.sh --folder '.' --kubeconfig ./kubeconfig --kubermatic-domain kubermatic.test.com --letsencrypt-prod

This will generate the files used for the installation in the root directory:
