Containers

Caddy offers a great web and proxy server experience with minimal configuration and automated TLS certificates. Learn how to connect Caddy to Porkbun to get TLS certificates by managing your DNS records for you automatically. 🐷

Here’s a blog post to answer the question: Why do you write so much about CoreOS? 📦

Sure, docker-compose is great, but could we get similar functionality using just the tools that are built into CoreOS? Can we get automatic updates, too? Yes we can! 📦

I woke up one morning to find my Ghost blog unresponsive. It required an unexpected fix. 🔧

Ghost delivers a great self-hosted blogging platform that deploys well in containers. Let’s deploy it on CoreOS along with Caddy. ️📝

Podman’s new quadlet feature lets you specify container launch configuration via simple systemd-like unit files. 📦

CoreOS provides a fast track to running containers with a light weight immutable OS underneath. This doesn’t mean that you can’t keep it around as a pet instance. 🐕

Watchtower keeps an eye on your running containers and updates them when new containers appear upstream. 📦

Although my first attempt at self-hosting Mastodon was a failure, I went back for a second attempt with docker-compose. 🧗‍♂️

My go-to method for managing containers easily is still docker-compose. It works really well on Fedora CoreOS. 📦

Ongoing changes at Twitter led me to take a second look at mastodon, including running my own mastodon instance. 🐘

Access files over NFS within kubernetes pods with a quick volume mount. 🗄

Package up graphical applications in containers and run them with podman. 🚢

Re-use the same wildcard TLS certificate for multiple containers running behind traefik. 🚦

Run rootless Linux containers without any daemons using docker-compose and podman on Fedora! 📦

Many cloud providers give you lots of memory with each instance and you can speed up tests and builds by using a ramdisk.

Buildah and podman work well with the vfs storage driver, but the default mount options can cause problems.

My team at Red Hat depends heavily on GitLab CI and we build containers often to run all kinds of tests.

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

It seems like there’s a new way to run containers every week.

I’ve been getting involved with the Fedora Security Team lately and we’re working as a group to crush security bugs that affect Fedora, CentOS (via EPEL) and Red Hat Enterprise Linux (via EPEL).

The world of containers is constantly evolving lately.

Getting started with LXC is a bit awkward and I’ve assembled this guide for anyone who wants to begin experimenting with LXC containers in Fedora 20.

Docker is a hot topic in the Linux world at the moment and I decided to try out the new trusted build process.
