The easiest way to configure your cluster is to use one of the included
.profile configuration files and overwrite the variables you need.
Then you can invoke the k8s-setup script with any of the commands
accepted by Terraform.
For example:
$ ./k8s-setup -F base-openstack.profile apply
(remember that, as a shortcut, k8s-setup invokes terraform with the
last argument, so this line generates a k8s-setup.tf and then invokes
terraform apply)
You can overwrite profile variables with the -V argument. For example:
$ ./k8s-setup -V kube_minions_size=6 -F base-openstack.profile apply
or with an additional configuration file:
$ echo "kube_minions_size=6" > local.profile
$ ./k8s-setup -F base-openstack.profile -F local.profile apply
If you want to review the generated k8s-setup.tf file, you can also
obtain a prettified version of this file with:
$ ./k8s-setup -F base-openstack.profile fmt
and then run any terraform command with this file.
After running terraform apply you will find an environment like this:
Then you need to run the Salt orchestration in order to install and configure all the Kubernetes components.
