GitOps Sandpit Environment

Background

Contains a Vagrantfile which will launch a fully functional GitOps environment which includes the following:

• Kubernetes v1.19.3
• Flux v1.5.0

Install Instructions

1. Fork the https://github.com/cloudacademy/gitops-demo repo
2. Edit the Vagrantfile, update the FORKED_GITOPS_DEMO_REPO variable to point to your forked copy
3. Launch the GitOps Vagrant box using vagrant up
4. Extract the Flux SSH public key from the output of the previous command and then add it as a new Deploy Key with both read/write access for the forked repo as configured within the FORKED_GITOPS_DEMO_REPO variable
5. SSH into the new GitOps Vagrant box using vagrant ssh

Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "cloudacademydevops.k8s"

  config.vm.provision "shell", inline: <<-SHELL
