How to deploy on Canonical Kubernetes

Canonical Kubernetes is built on Ubuntu and combines security with optimal price-performance. Canonical is a Certified Kubernetes Service Provider, your trusted advisor for a successful cloud native strategy. This manual shows you simplicity of deploying Charmed MySQL K8s to Canonical Kubernetes.

Summary

Assuming you have a spare hardware/VMs running Ubuntu 22.04 LTS (or newer). The only necessary steps will be:

• Install Canonical Kubernetes
• Install Juju
• Deploy Charmed MySQL K8s

Install Canonical Kubernetes

Follow the official and detailed guide or simply run:

sudo snap install k8s --edge --classic
sudo k8s bootstrap
sudo k8s status --wait-ready

Once Canonical K8s is up and running, enable the local storage (or any another persistent volumes provider, to be used by Juju Storage later):

sudo k8s enable local-storage
sudo k8s status --wait-ready

(Optional) Install kubectl tool and dump the K8s config:

sudo snap install kubectl --classic
mkdir ~/.kube
sudo k8s config > ~/.kube/config
kubectl get namespaces # to test the credentials

Install Juju

Install Juju and bootstrap the first Juju controller in K8s:

sudo snap install juju --channel 3.6/candidate
juju add-k8s ck8s --client --context-name="k8s"
juju bootstrap ck8s

Deploy Charmed MySQL K8s

juju add-model mysql
juju deploy mysql-k8s --trust

follow the deployment progress using:

juju status --watch 1s

Example output:
