This article demonstrates how to get a web site running using Docker. We’re starting with a Linux server (doesn’t matter which distribution). We’re going to pull down an Docker image from the public repository, modify it’s “index” file, and expose it – making it publicly accessible. I’ve added a littleRead more
Acquire AGIX Support For Kubernetes & Docker
The AGIX team of technicians has plenty of experience in deploying Docker containers and has written plenty of Kubernetes articles in the AGIX technical block which is freely available to anyone interested in DIY computing.
Kubernetes & Docker Case Study
More systems are being distributed by Docker containers (images) in recent times due to the reliability and consistency of such a distribution method. AGIX clients often request new systems which can easily and quickly be deployed using Docker.
The time saved by using Docker compared with traditional distribution and deployment methods is considerable, and the money savings is significant.

This article walks through the process of creating a self-hosted Docker Registry. We’re using Ubuntu but given that Docker is basically cross-platform (in a way), this should work on any Linux distribution. You can host your Docker Registry on any host you like. When I refer to you “Docker RegistryRead more
In this article we’re going to walk through installing Docker on Ubuntu, starting a few Docker containers, and then running those containers behind a reverse proxy. When we’re done, you’ll have a load balance terminating SSL (TLS) connections with multiple Docker containers running the workload. This is how it willRead more
This article shows how to install Docker for Windows 10 (and probably 11), and then start a web server in a Docker container. Install Docker Visit “https://www.docker.com/products/docker-desktop” and download Docker installer. Start the installation process (you’ll need local admin privileges). During the installation process, the wizard will ask if youRead more
The good news is that Microk8s can now be deployed in a multi-node architecture. And it’s simple to do. This video “https://www.youtube.com/watch?v=dNT5uEeJBSw” is a nice demonstration. It uses a floating IP between the cluster nodes that removes the need to use a load balancer in front of your cluster. StartRead more
This article continues from Part 2 – Replica Sets and Scaling. Our objective in this article is to get an application exposed to the wider network on an IP address of the host and a port of our choice. The IP address will be “10.0.0.210” and our port of choiceRead more
This article continues from Part 1 – Installation and configuration. We can create a replica set (replicateset) or “rs” for short, so we can scale an application to meet demand. Create a file on the Kubernetes host called “my-rep-set.yaml” and populate it with the following: Tip: This is just anRead more
This article walks you through the process of installing the minimal Kubernetes environment on Ubuntu 20.04. Kubernetes comes in two forms; a single node cluster and a multi-node cluster. In this walk through, we’ll be using the single node cluster called MicroK8s. I suggest starting with a Ubuntu 20.04 serverRead more
This article is quick walk-through explaining how to install Bitwarden on Fedora 32 but should work on CentOS 7 and 8 as well as RHEL. Install the docker packages: yum install docker docker-compose systemctl enable docker systemctl restart docker Download the Bitwarden scripts: curl -Lso bitwarden.sh https://go.btwrdn.co/bw-sh chmod +x bitwarden.shRead more
This article describes how to install OpenShift Origin (the community version) on a Redhat or CentOS 6.4 server. We’re doing this as a test on an AWS EC2 CentOS 6.4 (With Updates) and a machine type of “m3.medium”. Do this on a fresh system, not one that has real previousRead more
