Kubetool version and ip options behavior about puppetlabs-kubernetes HOT 4 CLOSED

@Bengrunt IP is the public ip address for the cluster. This added that address to the SSL certificates for the cluster.

If you create the cluster configuration with the kubetool docker run -v $(pwd):/mnt -e OS=debian -e VERSION=1.9.1 -e CONTAINER_RUNTIME=docker -e FQDN=kubernetes -e IP=172.17.10.101 -e BOOTSTRAP_CONTROLLER_IP=172.17.10.101 -e ETCD_INITIAL_CLUSTER="etcd-kube-master=http://172.17.10.101:2380" -e ETCD_IP="%{::ipaddress_enp0s8}" -e KUBE_API_ADVERTISE_ADDRESS="%{::ipaddress_enp0s8}" -e INSTALL_DASHBOARD=true puppet/kubetool It will automatically update both for you in hiera.

For example

kubernetes::kubernetes_version: 1.9.1
kubernetes::kubernetes_package_version: 1.9.1-00

Hello @scotty-c. Thanks for the quick answer :)

OK for the ip param, I guess I got mislead by an older version of the doc where it was mentioned -e IP=172.16.0.0/16 or something similar.

So I managed to get a little further in the deployment process but I'm still stuck. :/

I started looking at the code and found why I ended up with an empty kubernetes_package_version. These lines of code suggest only two possibilities for the OS parameter: redhat and debian.

if os.downcase.match('debian')
  kubernetes_package_version = "#{version}-00"
elsif os.downcase.match('redhat')
  kubernetes_package_version = version
end

Since I was using centos it left the package version empty without any warning. I don't know if there is a need for support of additional values but I feel it would be helpful if the docs mentioned the possible options.

On an unrelated note, I'm still wondering if and how I could choose which version of docker to install? By default on centos7 I get docker v1.12.6 but I feel like I would rather have the latest docker-ce distribution for instance.

Moreover, my org requires me to use a specific IP range for the cluster internal network, there does not seem to be a place to set this info. I did find this line in params.pp though, so I tried to set kubernetes::cni_network_provider: https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d "\n")\&env.IPALLOC_RANGE=172.20.0.0/16 in hiera, but I'm not sure it's the right way to go...

Sorry for all this bunch of questions. I felt like sharing these here since it might be useful for other beginners like me. Anyway, thanks a lot!

@Bengrunt They are puppet OS family facts so CentOS would be in the RedHat family. We are supporting Docker 1.12 with this module or cri-containerd as the supported runtimes, not all version of Docker are compatible with Kubernetes. But both 1.12 and cri-containerd are heavily tested.

In regards to the ip range for Weave you can change the ip address range in hiera, in saying that if you are new to Kubernetes I would read about CNI and the weave documentation before doing so
