So here’s the story so far: In parts 1 and 2 of my Kubernetes intro story, we have set up a Minikube Kubernetes Cluster. We then deployed a container with an app inside, which was downloaded directly from the Kubernetes image hub, into our cluster. Our cluster is small, it only contains one worker node … Continue reading Kubernetes Intro – Part 3 – Create, Dockerize and Push Into the Cluster
In the previous episode, I’ve moved a WordPress Blog from the simple installation of part 1 to the more sophisticated reverse proxy setup I have put together in part 3 to demonstrate that containers are ‘portable’ between different servers with little effort. Moving the container also showed that the nginx-gen container recognizes when new containers … Continue reading Dockerize Me – Containers Managing Containers – Part 5
In part 3 of this series we’ve created a reverse proxy setup with Docker containers in the public cloud to serve the content of several web services from independent docker containers with individual domain names. In this episode I’ll test the concept that containerized applications can easily be moved from one host to another.
After the basic installation of Docker and getting a WordPress blog up and running in Docker containers in part 1, this part of my Docker series will take a look at how to add two important features to the setup: TLS certificates and LetsEncrypt with auto-renewal How to host several websites on one server that … Continue reading Dockerize Me – Several Services and LetsEncrypt – Part 3
In part one of my ‘Dockerize Me’ story, I’ve been describing the reasons why I want to learn more about Docker and gave some first tips and tricks how to quickly install it with a few commands on a Debian based server. A first docker-compose project then demonstrated how to quickly spin-up a WordPress container … Continue reading Dockerize Me – Cheat Sheet and Pyramid of Trust – Part 2
Over the years I’ve been looking at Docker every now and then. That’s because for one thing I am interested in the concept of deploying software in lightweight containers instead of VMs and also because I am running two pieces of software in Docker containers on my servers as well. But that was it until … Continue reading Dockerize Me – My Personal Docker Bootstrap Voyage – Part 1
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
