Cozystack Demo

This is a test repo for Cozystack, we are using it in our home lab to prove the integration of Cozystack and Flux-Operator as a process, and to be familiar with tear-down stand-up workflow for our Disaster Recovery scenarios.

Time trials are on YouTube (some are linked at the bottom of the page!)

tl;dr

make mrproper
make init
git stash
make apply
make monitor-nodes-reboot
make bootstrap
make kubeconfig
# kconf rm admin@cozystack
kconf add kubeconfig
make install

# ... (wait a while!)
flux get helmreleases -A

# and see that Cozystack is installed! 🤞

That's literally as short as I can make it 😅 you should probably read on if you want to know how this works at all, in order to better follow my example.

How to use

To use this repository:

  • make mrproper - this WILL wipe out talosconfig and kubeconfig in ./, as well as the "talm chart"

  • make clean-nodes to wipe out the definition of nodes (my homelab nodes, you'll want your own!)

  • make init for a default talm init --preset cozystack config (the "talm chart")

  • git diff Nb. any differences eg. in the cozy-config - commit any important changes

  • git stash (we don't want the default network, so we'll put those changes aside)

  • Follow the instructions at cozystack.io: Configuration - Talm eg. talm template to generate your own controlplane and/or worker nodes

You'll need to run template once for every node that you have. (I have make template shortcut)

  • make apply and wait for both nodes to upgrade themselves, they will reboot, give a minute
  • (if you have different nodes, you'll just use talm apply -f nodes/foo.yaml -i once for each node)

Now you are ready to bootstrap Kubernetes on Talos, and install Cozystack!

  • talm bootstrap -f nodes/hpworker01.yaml - this is my one control-plane node, bootstrap once
  • make kubeconfig or talm kubeconfig kubeconfig -f nodes/hpworker01.yaml - get the admin@cozystack Kubeconfig

Now follow Get Started guide starting from the Install Cozystack section, to continue the installation.

(Congratulations, you just set up Talos Linux, btw!)
