## Hands-on sesesion

### Preparation

You need 
- a GitHub account (to access this material and setup gitops flow)
- a working Kubernetes in the hands-on session (to s)
  - [multipass VM](#local-multipass-VM) (local installation, recommended)
  - [DigitalOcean VM] (remote installation)


#### multipass VM

1. Install multipass on https://multipass.run
  - support Windows 10 Pro+, Mac OS X, Linux
  - Mac OS X (with homebrew installed): `brew cask install multipass`
  - Ubuntu (or any Linux distro with snap installed): `sudo snap install multipass --classic`
2. Start Command prompt / Terminal
3. Execute `multipass launch -d 30G -m 2G --name fluxcd-workshop 18.04`
4. Depends on network condition, you need to wait for 5-20 mins.
5. Execute `multipass shell fluxcd-workshop` to obtain shell in the VMs


6. Execute `curl -sfL https://get.k3s.io | sh -` in the VM
7. Depends on network condition, you need to wait for 5-10 mins.
8. You should have your local Kubernetes cluster installed. To verify, execute `sudo kubectl get nodes`, it should give you something like
```
NAME              STATUS   ROLES    AGE     VERSION
fluxcd-workshop   Ready    master   5m53s   v1.18.3+k3s1`
