I’ve been experimenting with OpenShift lately and in the following post I’d like to document the steps required to get an OKD 3.11 environment up and running. For those who are not familiar with the OKD abbreviation it is “The Origin Community Distribution of Kubernetes that powers Red Hat OpenShift”. The deployment is going to be set up on a single node and configured to use Let’s Encrypt SSL certificates for the API endpoint/console and HTTPS routes.

For this weekend project I had to migrate a couple of wordpress websites away from an existing server that I’m going to decommission soon. The current environment consists of a traditional setup with nginx and php-fpm running as systemd services on a CentOS VM with each website being configured within its own server block. This was, of course, an opportunity to come up with a new environment where I could experiment with some components that I’ve recently learned about.

I’ve been playing with Ansible lately and I was thinking of a good practice exercise. The first thing that came to mind was an HA cluster since clustered nodes get almost identical configuration and most probably you want to use a config management system to deploy and don’t touch them with any manual configuration.
