After dockerizing this blog with 15 years worth of content a couple of days ago and pushing it into a virtual machine running in a data-center in Helsinki, here’s an account of how to do this in case you are playing with the thought of doing something similar. As with many other things, everything one … Continue reading Dockerizing An Existing WordPress Site
Like most conferences in the first half of 2021, the Chemnitzer Linux Tage (Chemnitz Linux Days) on the 13th and 14th of March will be held online. Apart from very interesting talks about Linux-related topics, most of them in German, the conference also offers a broad range of workshops. While I like to give talks, … Continue reading I’m Giving An Online Docker Hands-On Workshop
I’m almost happy with the basic hands-on understanding I have gained about Kubernetes about which I have written in part 1 to 3 of this series. I understand much better now how Kubernetes manages Docker containers, how it abstracts and manages the distribution of containers in a cluster of servers and how it makes services … Continue reading Kubernetes Intro – Part 4 – Persistent Storage
In part 1, I’ve given an introduction to my path to learn more about Kubernetes with a hands-on approach. The story ended with Minikube being installed and a first sample application (the ‘http echosever’) up and running in a container that is managed by Kubernetes. With all of this in place now, the next logical … Continue reading Kubernetes Intro – Part 2 – The Dashboard
When we are talking about the 5G Core and implementations based on containers the story does not end with Docker containers. As a 5GC is not only based on one server and needs lots of redundancy, a management (orchestration) tool is required to manage containers across a large number of servers. There are several tools … Continue reading Kubernetes Intro – Part 1
Before I installed my first Jitsi server I thought that it must be quite a complicated affair. I searched around a bit and found a simple way to install it via a docker-compose script. The Docker script sets up a couple of Docker containers that encapsulate the different programs required to run the Jitsi-meet server … Continue reading Installing a Jitsi Server – Apt vs. Docker
In the previous blog entry, I’ve been looking at a number of different commercial video conferencing solutions and if they offer native Linux support. There are a couple of fabulous products with good Linux support out there that easily support sessions with 15-20 simultaneous video participants. Unfortunately, from a privacy and confidentiality point of view, … Continue reading Jitsi Meet and the Number of Video Participants
As I hinted in my 37c3 post, I was using a bit of time at ‘Congress’ to improve the structure of my containers in the cloud. While I have quite a number of projects running in dedicated virtual machines, I have containerized others such as this blog, my MediaWiki, an OnlyOffice instance, Etherpads and a … Continue reading Container Games – Private Networks for Private Containers
Infrastructure as code they say, so I built myself a wonderful Ansible script to update my virtual machines and container installations on a regular basis without manual intervention. This has worked superbly in the past two years or so, but this week I was bitten. When I searched something in my (containerized) MediaWiki instance today, … Continue reading Container Games: When LATEST is not the greatest, and how it broke my MediaWiki
Those of you who have been to ‘Congress‘ before know it’s a special event for anyone even remotely nerdy. It always takes place between Christmas and New Year’s Eve and I was lucky enough to get a ticket. It seems they still remembered I gave a talk there about 5G last time around. After not … Continue reading 37C3 – Martin @ Congress
