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
In part 3 of my Dockerize-Me series I’ve been looking at how to run several web services on the same server, make them accessible on the same ports (80 for http and 443 for https) and add Letsencrypt TLS certificates for secure communication. This is typically done with a reverse http proxy setup as described … Continue reading Dockerize-Me: Traefik as Reverse-Proxy – Part 6
It’s the time of the year again to have a look back at the things that moved me this year. On the surface, it seems that I had relatively few posts about wireless network technologies. But this appearance is quite deceptive.
After the six ‘Dockerize Me‘ and four ‘Kubernetes Intro‘ episodes that mainly dealt with getting a good understanding of how to use containers, the time has come for me to deal with the ‘end boss‘ of the game: Dockerizing the web-based database system I’ve been working on in my quality time over the years. I … Continue reading App To Docker – Part 1 – Volume Magic
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
It’s amazing how in the past year or so, efforts in the telecom industry to move next generation systems into containers and manage them with Kubernetes have moved from theory to practice. The 5G core, for example, was specified by 3GPP in a cloud native way from the start, and even things like Open Radio … Continue reading Kubernetes Intro – Part 5 – A Cluster on Amazon and Linode
