Fortunately, there are apps like Portainer that exit of their method to make managing and deploying containers exponentially simpler than doing so from the command line. With Portainer, you may handle Docker containers, stacks, photos, networks, volumes and extra, however some of the spectacular options is its capability to deploy a full-stack utility from a easy app template.

What you’ll have to deploy a full-stack utility
The solely factor you’ll have to comply with alongside on this tutorial is a working occasion of Portainer. I like to recommend deploying Portainer to a MicroK8s atmosphere after which installing Docker CE on the controller so that you add a Docker atmosphere into the combo.

A list of the out there utility templates will seem. Let’s take a look at out the WordPress deployment. Scroll down till you see WordPress (Figure C).

It will take a while for the deployment to finish, however as soon as it’s completed, you’ll be taken again to the Stacks itemizing. Click on the newly deployed WordPress stack, and also you’ll see the printed port listed (Figure F).

Give the containers loads of time to spin up after which level your browser to http://SERVER:PORT, the place SERVER is the IP handle of the controller node and port is the printed port you noticed while you considered the newly-deployed stack. You will likely be greeted by the WordPress installer (Figure G), the place you may level and click on your method to ending the deployment.

Full stacks made easy
You received’t discover a better method to study the artwork of deploying a full-stack utility with Docker. Using Portainer enormously simplifies the deployment and administration of containers. Once full-stack builders begin utilizing Portainer, they’ll surprise how they ever managed with out it.
