Deploy Containerd, Kubernetes, Calico, MetalLB for development ONLY

Overview

This is not a deployment project, but simply my tooling for doing development work. I don't feel the world needs yet another K8s deployment system, however, I need something simple and understandable for my own development which involves contribution to Istio project and the cloud native ecosystem. I wrote the Ansible code in about an hour so its not great, and is probably buggy. If you submit PRs to fix bugs, I will accept them. PRs for features may not be accepted. Please slack me if you are thinking of adding anything complex, so you don't waste your time :)

This code deploys the following:

• containerd
• Kubernetes
• Calico
• MetalLB

Please read the license. There is ABSOLUTELY NO WARRANTY. If you run these playbooks on an existing cluster, they may eat your system.

Directory Layout

Directory	Purpose
K8s-v1.14	deploy K8s v1.14 with kubeadm AIO
K8s-v1.17	deploy K8s v1.17 with kubeadm AIO
K8s-v1.18	deploy K8s v1.18 with kubeadm AIO
K8s-v1.19	deploy K8s v1.19 with kubeadm AIO
ansible	Deploy a control plane and a bunch of workers using an ansible playbook with kubeadm

Using Ansible

Prereqs

• Ensure you have passwordless sudo setup on every node in your inventory.
• Do not run as user root.
• Instead run as your local user.
• Ensure containerd 1.3.3 or later is installed. This tooling does not depend on Docker, only containerd from ubuntu. You may be able to install containerd with ansible-playbook -f setup-containerd.yml. This may or may not work. I have not done a final validation of my system from initial deployment to determine if the code is correct.

Usage

1. Copy the yaml files form the K8s-v1.y directory to your home directory.
2. Modify the inventory with the ip addresses of your machines.
3. Modify the advertise address to your control plane IP address in onprem-1y.yaml.
4. Run the do.sh script with -c create or -c destroy.
