vsphere-kubernetes

Infrastructure-as-Code Project to deploy a fully-automated Kubernetes environment leveraging VMware vSphere, Ubuntu,and Ansible.

To deploy the environment, perform the following steps:

1. Modify the 'envanswer.yml' file to include the environment-specific URLS, usernames, passwords, and additional configuration information.
2. Run the Ansible playbook 'deploy_vsphere.yml' to deploy the vSphere components.
3. Run the Ansible playbook 'vcenter-generate-inventory.yml' to create the inventory file for the environment.
4. Run the Ansible playbook 'deploy_kubernetes' to install and configure Kubernetes.

Prerequisites

The vSphere environment requires an Ubuntu 22.04LTS template to clone the VMs from.

Ansible Playbooks for SDDC deployment

These are the individual Ansible Playbooks leveraged to deploy Kubernetes inside a VMware SDDC environment

• kube-cntlr-deploy.yml: Deploy master or controller nodes for Kubernetes cluster
• kube-nodes-deploy.yml: Deploy minion nodes for Kubernetes cluster
• kube-nodes-hw.yml: Modifies the CPU and Memory configuration of minion nodes
• kube-drs-rules.yml: Create DRS anti-affinity rules for controllers
• vcenter-generate-inventory: Create Ansible inventory file with correct VM names and IP addresses

Ansible Playbooks for Kubernetes deployment

• disable-swap.yml: Disables swap inside the OS for each nodes
• install-k8s-packages.yml: Installs all the necessary Kubernetes packages and prerequisites inside Ubuntu
• containerd-workaround.yml: (Optional) Known issue with containerd /etc/containerd/config.toml file
• initialize-kubernetes.yml: Initializes the Kubernetes cluster, deploys Antrea CNI, adds both controllers + workers to cluster
