Vagrant: Build a highly available kubernetes cluster

Vagrant project to spin up a local highly available kubernetes cluster for development and testing purposes. See https://github.com/gadgieOps/ha-kubernetes.git for further information on the underlying ansible code.

Dependencies

Required roles:

• gadgieOps.ha-kubernetes

Can be installed using:

ansible-galaxy install -r requirements.yml

Usage

1. In the Vagrantfile
   • Set CONTROLLER_N to specify the number of control plane nodes to spin up
   • Set WORKER_N to specify the number of worker nodes to spin up
2. Modify inventories/nodes.yml to match the quantities of nodes
   • It may be simpler to comment out any unrequired nodes
3. Customize role vars in playbooks/provision-cluster.yml for further information
   • See https://github.com/gadgieOps/ha-kubernetes.git
4. Use 'vagrant up' to spin up the cluster
5. Use 'vagrant halt' to turn off the cluster
6. Use 'vagrant destroy' to destroy the cluster

Collaboration

Please feel free to raise issues and submit pull requests. I have been using this role along side Vagrant to spin up dev and test environments that are in line with my production environment. I am working on making this role more generic and accessible for other usecases.

Notes

Tested using:

• Ubuntu 20.04
• CentOS 7.9
