I explain how I connected Node-RED with my Home Assistant (HASS), considering that they run on separate servers. They are deployed on different virtual machines, to allow independent maintenance and improve their performance. For your reference, I created another post here where I describe the Node-RED installation using Alpine and Docker underneath, running as a virtual machine on my KVM server. …
Node-RED is a programming tool that allows you to connect hardware devices, APIs, and cloud services through creative workflows. Everything is done from the browser, and it supports dozens of built-in and third-party nodes. Here I’ll explain the installation process, on a virtual machine with Alpine and Docker underneath. If you’re interested, I have another post describing how I integrate it with my Home Assistant. …
In this post I describe the installation of Gitea (GIT server) and Traefik (LetsEncrypt SSL certificate termination), along with Redis (cache) and MySQL (DB). I install all applications as Docker containers on an Alpine Linux running as a virtual machine on my KVM server. In the previous post I explained what Gitea is and how to set it up directly on a virtual machine (without Docker). …
GIT is a distributed version control system, and we all know the famous centralization services GitHub and GitLab. I recently came across a promising alternative called Gitea - Git with a cup of tea and decided to install it on a virtual machine. …
In this post I describe how to install Alpine Linux in a virtual machine on my QEMU/KVM server and how to install Docker on it. I needed, for proof-of-concept and home services, the ability to run containers on a Docker host that takes up “very little” space. Can you install a Docker Host on top of a Virtual Machine? The answer is a resounding yes — in fact, it’s an excellent place to do so, especially in lab environments, home setups, and small deployments. …
It was about time I played with Open vSwitch (OVS). I’m going to take advantage of setting up a new server with Ubuntu Server, KVM, Virtual Machines, and VLANs to build everything with Open vSwitch instead of the traditional Linux Bridge. OVS is a virtual bridge from which I’ll manage all network connections for both the server itself and its virtual machines. Some VMs will receive a Trunk interface while the majority will connect in Access mode to a specific VLAN. …
