Hi @bitvijays

Currently the kubernetes_apt_location parameter defaults to https://apt.kubernetes.io and as you can see from the error message this is an apt error. There are different workaround if you want to install Kubernetes on Ubuntu Bionic but, for now, this module is compatible with Ubuntu Xenial as shown in the metadata.json of this module.

@carabasdaniel Hope you re doing well. Thank you for your response. My apologies, would it be possible for you to tell me a simplest workaround? Is there a way we can change the kubernetes_apt_location of any other variable to get Kubernetes installed?

[catsem]

I had the same issue.
With the following config in my Ubuntu.yaml I could setup the cluster in ubuntu bionic:

kubernetes::kubernetes_version: 1.17.3
kubernetes::docker_apt_location: "https://download.docker.com/linux/ubuntu"
kubernetes::docker_apt_release: "bionic"
kubernetes::docker_apt_repos: "stable"
kubernetes::docker_key_source: "https://download.docker.com/linux/ubuntu/gpg"
kubernetes::docker_key_id: "9DC858229FC7DD38854AE2D88D81803C0EBFCD88"
kubernetes::docker_version: "5:19.03.63-0ubuntu-bionic"
kubernetes::docker_package_name: "docker-ce"
kubernetes::cgroup_driver: "systemd"

IMHO kubernetes and this module should finally start to support ubuntu 18.04 as the current LTS. It's already on the market for about 2 years now and even worse, 16.04 is hitting it's end of standard support next year.

@carabasdaniel Hope you are doing well. Would it be possible to add @catsem suggestion in the Readme.md? May be in a subsection.

Just a example below

Installing a updated version

If you want to install a updated version/ customise the installation, please change the below parameters:

kubernetes::kubernetes_version: 1.17.3
kubernetes::docker_apt_location: "https://download.docker.com/linux/ubuntu"
kubernetes::docker_apt_release: "bionic"
kubernetes::docker_apt_repos: "stable"
kubernetes::docker_key_source: "https://download.docker.com/linux/ubuntu/gpg"
kubernetes::docker_key_id: "9DC858229FC7DD38854AE2D88D81803C0EBFCD88"
kubernetes::docker_version: "5:19.03.63-0ubuntu-bionic"
kubernetes::docker_package_name: "docker-ce"
kubernetes::cgroup_driver: "systemd"

@catsem Would it be possible for you to send a PR for the Readme.md? If @carabasdaniel is fine with the suggestion?
