If you wish to include Kubernetes to your development workflow, try the easy route with this Microk8s and Portainer mix.

It was only a number of months ago that I wrote a TechRepublic tutorial on releasing Portainer to a Microk8s cluster for simplified Kubernetes development. Now that tutorial no longer works, because the current versions of Microk8s have trouble clustering, and the variations of Microk8s prior to 1.24 won’t work with Portainer. Keep reading to find out the new process of releasing this all-in-one container management platform to a Microk8s cluster.

What you need to release Portainer to Microk8s
You’ll need a Microk8s cluster with a minimum of 3 nodes and a user with sudo opportunities.
How to set up Microk8s and join the cluster
Here’s a fast refresher on how to release a Microk8s cluster correctly.
- Set up version 1.24 of Microk8s on all Ubuntu Server nodes through breeze.
- Modify your/ etc/hosts submit to map hostnames to IP addresses.
- Set the hostnames for each device.
- Set the proper timezone on all devices.
- Run the microk8s add-node command on the controller.
- Run the microk8s sign up with command, shown in the output of the add-node command, on every node.
- Add your user to the microk8s group with sudo usermod -aG microk8s $USER.
- Change the permission of the.kube folder with chown -f -R $USER ~/. kube.
- Log out and log back in.
Now that you have your cluster up and running, it’s time to deploy Portainer to the cluster.
How to release Portainer to a Microk8s cluster
Initially, enable a few add-ons to Microk8s. Log in to your Microk8s controller and issue the following commands to allow the essential add-ons:
microk8s make it possible for dns
microk8s enable ha-cluster
microk8s make it possible for ingress
microk8s allow metrics-server
microk8s make it possible for rbac
microk8s make it possible for hostpath-storage
Before allowing Portainer, you must allow the neighborhood repository with the command:
microk8s allow community
Now, you can enable Portainer with:
microk8s allow portainer
Offer Portainer adequate time to spin up– you can examine the status with the following command:
microk8s kubectl get pods -n portainer
When you see Portainer noted as running, you can open a web internet browser and point it to http://SERVER:30777 or https://SERVER:30799, where SERVER is the IP address or domain of the hosting server.
You will be triggered to create an admin user. After you take care of that, select the local environment, and you’ll discover yourself on the Portainer Control Panel (Figure A), where you can start managing your Kubernetes releases.

cluster. Watch for the latest releases of Microk8s Now you know how to appropriately deploy Portainer to a Microk8s cluster; however, given that this could change, you ought to expect the latest releases of Microk8s on the Snap shop. As soon as the most recent steady version of Microk8s is better capable of clustering, I extremely advise you upgrade to that release and re-deploy Portainer.
