Inspecting OpenShift cgroups from inside the pod

My team at Red Hat builds a lot of kernels in OpenShift pods as part of our work with the Continuous Kernel Integration (CKI) project. We have lots of different pod sizes depending on the type of work we are doing and our GitLab runners spawn these pods based on the tags in our GitLab CI pipeline. Compiling with make When you compile a large software project, such as the Linux kernel, you can use multiple CPU cores to speed up the build.

Running Ansible in OpenShift with arbitrary UIDs

My work at Red Hat involves testing lots and lots of kernels from various sources and we use GitLab CE to manage many of our repositories and run our CI jobs. Those jobs run in thousands of OpenShift containers that we spawn every day. OpenShift has some handy security features that we like. First, each container is mounted read-only with some writable temporary space (and any volumes that you mount).

Running Home Assistant in a Docker container with a Z-Wave USB stick

The Home Assistant project provides a great open source way to get started with home automtion that can be entirely self-contained within your home. It already has plenty of integrations with external services, but it can also monitor Z-Wave devices at your home or office. Here are my devices: Monoprice Z-Wave Garade Door Sensor Aeotec Z-Stick Gen5 (ZW090) Fedora Linux server with Docker installed Install the Z-Wave stick Start by plugging the Z-Stick into your Linux server.

Disable autoplay for videos in Firefox 65

Firefox has some great features, but one of my favorites is the ability to disable autoplay for videos.

This feature stopped working for me somewhere in the Firefox 65 beta releases. Also, the usual setting in the preference page (under Privacy & Security) seems to be missing.

Use a secret as an environment variable in OpenShift deployments

Environment variables are easy to add to OpenShift deployments, but a more secure way to add these variables is by referencing a secret.
