Auto-K8s

This project is focused to deploy Kubernetes clusters for development using Vagrant virtual machines

Environment

Tested on:

• Fedora 34
• Fedora 39

Requirements

• Vagrant
• Ansible

# Install packages
sudo dnf install -y ansible vagrant-libvirt qemu

# Start and enable libvirtd
sudo systemctl enable libvirtd
sudo systemctl start libvirtd

# Add our user to libvirt group
sudo usermod --append --groups libvirt `whoami`

Deployment

Create VMs

export AUTO_K8S_FLAVOUR=<FLAVOUR>
cd vagrant
vagrant up
vagrant status
cd ..

Launch Ansible

# To install Kubernetes
ansible-playbook -i inventories/${AUTO_K8S_FLAVOUR} -b site.yaml

# To remove Kubernetes
ansible-playbook -i inventories/${AUTO_K8S_FLAVOUR} -b clean.yaml

Flavours

1. Simple: Simple k8s cluster without storage, single master node and two workers.

   export AUTO_K8S_FLAVOUR=simple
   cd vagrant
   vagrant up
   vagrant status
   cd -
   ansible-playbook -i inventories/$AUTO_K8S_FLAVOUR -b site.yaml

2. NFS-Storage: Deploys one master and two workers and a fourth server for providing NFS Storage.

   export AUTO_K8S_FLAVOUR=nfs-storage
   cd vagrant
   vagrant up
   vagrant status
   cd -
   ansible-playbook -i inventories/$AUTO_K8S_FLAVOUR -b site.yaml
   
   # Test
   export KUBECONFIG=./build/kubeconfig
   kubectl apply -f inventories/nfs-storage/nfs-storage-test.yaml

Accessing Kubernetes

export KUBECONFIG=./build/kubeconfig
kubectl get nodes
kubectl get pods -A
