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
One tool that has become absolutely essential to me for note taking and finding information again is a Wiki. A very long time ago, I initially used WOAS, a personal Wiki platform that was basically a local HTML file that could be modified in the browser. It was a nice system, but at some point, … Continue reading Moving on to MediaWiki – Part 1
Back in July, I had a couple of posts how to get a ‘dockerized’ version of OnlyOffice to play with Nextcloud. The docker-compose.yml files I found at the time in the developer company’s resources downloaded and then built the OnlyOffice image locally. There’s nothing wrong with that, but it takes a bit to startup the … Continue reading Nextcloud – OnlyOffice Install – Self-Built vs. Docker Hub Image
For working collaboratively on text documents with others, I’ve been using Nextcloud and Libreoffice / Collabora Online. Unfortunately, Collabora Online must have been designed to be used on-premise, as the document rendering is done on the server. Any network delay noticeably slows down the output and generates other undesired side effects. So I decided to … Continue reading Online Word Processing – Part 4 – OnlyOffice and Nextcloud – For Real
So far, the public cloud has pretty much been ‘virtual machines’ for me, with varying numbers of CPUs, memory and storage, depending on the application. Recently, however, I’ve been looking for a way run copies of my home cloud based virtual machines (VMs) and Docker containers in a data center for redundancy purposes. For this … Continue reading Bare Metal in the Cloud – Part 1 – Let’s Rent Hardware
Wow, this is part 10 in my series on how to get started with Kubernetes! I am obviously having a lot of fun with the topic, and it’s really nice to be able to experiment with the technology, as it is not only the basis for 5G core networks, but massively transforms all parts of … Continue reading Kubernetes Intro – Part 10 – Persistent Storage in a Managed Cluster
And I’m moving along with the exploration of how to use a managed Kubernetes cluster. In the previous episode, I’ve gone into the details of how to deploy applications into a cluster and hook them up to an Ingress load balancer, so they are reachable from the outside. In this episode, I want to expand … Continue reading Kubernetes Intro – Part 9 – Deploying Your Own App
In part 5 of this series, I’ve been looking at how companies like Linode, DigitalOcean and Amazon offer managed Kubernetes cluster instances. In other words, they provide Kubernetes clusters in freely configurable sizes, which can then be used for projects. The approach is quite different from how I thought it would work: Effectively, you get … Continue reading Kubernetes Intro – Part 8 – Deploying Stuff into a Managed 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
In my first post on the topic, I’ve given an introduction to ‘Remotely‘, an open source and self-hostable remote support solution for Windows and Linux. I came away quite impressed but noted that in my virtualized setup, the connection to a supported device was often interrupted due to unknown reasons. Also, I hadn’t yet tried … Continue reading Remotely – Part 2
