This is a personal blog focused on computer software and hardware. Most
projects are implementing software and hardware for a homelab. What is a
homelab? I would say a homelab could be a single computer or dozens of
computers connected in a network. You can also integrate with computers
in the Cloud.
I will be using another Raspberry Pi to serve as a reverse proxy for my network. With Nginx Proxy manager, I can manage my proxy configurations in a web app. This application is a front end for nginx which is a very popular web server that also works for proxying TCP/IP connections and encrypting traffic.
Installing Nginx Proxy Manager
I will be managing this software with docker. If you have not worked with docker before, I have a blog post about the basics of docker and installation methods.
LXC is a system container manager. It offers a user experience similar to virtual machines but using Linux containers instead. LXC containers will share the kernel of the host operating system. If you are already using Proxmox, you can create LXC containers on Proxmox nodes and with the web UI. If you would like to set up Proxmox as a platform to host your virtual machines and containers, check out my previous post about installing Proxmox.
Portainer CE is a web application that you can use to manage containers running on systems that have docker installed. Today we will be deploying Portainer community edition to manage some containers. Portainer runs as a container and you configure it to manage an existing docker installation. Portainer is also compatible with some additional container platforms which I may explore at a later date.

Requirements
As of this post, Portainer can be deployed on the following:
All these Virtual Machines have gobbled up the RAM and CPU cores on my systems. Now I’m going to take a look at a different way to run software: Docker.

Docker and containers
Docker is an open-source project for automating the deployment of applications into containers. Docker containers can run anywhere, on your laptop/desktop, on a server, or in the cloud. Containers can run natively on Linux and Windows. However, Windows images can run only on Windows hosts and Linux images can run on Linux hosts and Windows hosts, where host means a server or a virtual machine. Containers also do not have to run with Docker. There are other container platforms.
There is a useful software application out there called Pandoc which is a Haskell library for converting from one markup format to another through a command line interface. Pandoc can convert between markdown, HTML, and proprietary formats like Microsoft Word.
Installing
The official site for pandoc includes instructions to install on multiple platforms such as Windows, Linux and macOS.
Ansible is an open-source software that uses python to provide an automation language. It uses YAML declarative files known as playbooks to describe tasks that are executed by Ansible. Ansible can configure computer systems, deploy software, and automate IT tasks at scale. Ansible does not require software to be installed on managed systems and utilizes protocols such as OpenSSH and WinRM to connect to systems. The official documentation has more detailed information on how to get started.
