Fedora CoreOS is a minimal operating system used for running containerized workloads that I’ve been wanting to experiment with for some time. Since my test infra is OpenStack based I’ll document below how to create a Fedora CoreOS OpenStack instance.
In this post I’ll document how to build and run containers with Podman. Podman is a tool which allows you managing OCI containers without the need for a daemon. It aims to provide parity with the docker cli options making it easy for users to transition to using this new tool. You can read more about the Podman motivation in this detailed article.
This is a quick post documenting the commands required for setting up Openshift users with the admin role:
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.
