Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime.
The beauty of Docker is how portable your applications become. Beyond that it also allows to version control our entire instance, providing a mechanism for quick rollbacks, updates, and audits. This tutorial will show you how to host your WordPress site with Docker by creating an image for it and deploying it.
Kubernetes (commonly shortened to “k8s”) is an open-source container-orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It works with a range of container tools, including Docker.
We previously looked at bringing up a WordPress website using the App Templates on http://docker.comp.dkit.ie. Today we will look at a much quicker way to do the same task, using a “Stack Template”.
Serverless computing is a cloud-computing execution model in which the cloud provider dynamically manages the allocation of machine resources.
Ghost CMS is a new blogging platform which is kinda similar to WordPress and may be a new game changer in the industry of blogging platforms. It is a fully open source, adaptable platform for building and running a modern online publication – powered by headless Node.js.
This tutorial is very similar to the previous one, except this time we will create our GitLab Runner on Docker. As we won’t be repeating a lot of the material, please read the other tutorial first.
In the last tutorial we look at adding local files to your Dockerfile for image deployment. This time, let’s look at at files from your project on the DkIT GitLab server.
If you read our recent tutorial series on using Docker Containers via a web frontend you may also be curious about Docker on the command line.
