This guide will go step by step in creating some web development infrastructure with Kubernetes, managed database, domain name and other stuff, ready to have a project deployed to it.
All of this will be done through a single configuration file, which I will write piece by piece in this article.
By trade I am a PHP developer. I’ve never done devops in a professional setting. However, for a while I have had a strange fascination with various continuous integration and deployment strategies I’ve seen at many of my places of work.
I’ve seen some very complicated setups over the years, which has created a mental block for me to really dig in and understand setting up integration and deployment workflows.
But in my current role at Geomiq, I had the opportunity of being shown a possible setup – specifically using Kubernetes. And that was sort of a gateway drug, which finally led me to getting a working workflow up and running.
I now want to share how I would set up a Kubernetes cluster in Digital Ocean, followed by how I set up projects – Laravel projects in my case – to automatically deploy to that cluster as part of a workflow.
First off I’d like to explain how I have the setup working; what happens and when.
On completion of a new feature branch, I will create a Pull Request
to merge it into the repository’s main branch in
Github.
Both pushing a branch to the repository and creating the Pull Request will trigger a Github Action. That Action will run
It’s probably easier to first get our heads around the main areas of the setup I use, before digging into each section in a separate post.
Setting up the Kubernetes Cluster itself
Setting up any API Keys and access keys / secrets
Configuring a web application to be deployed upon a certain condition (e.g. passing test-suite or manual deployment)
