So you’ve finished installing and configuring Portainer, and now you are ready to dive in and see what it can do. Portainer is a simple and lightweight, but powerful application that is used to provide a web management interface that you can use to perform functions on your Docker host. This guide aims to help answer some basic questions about how to use Portainer.
When you need to make a quick adjustment to your docker setup, you just fire up your favorite terminal app and start typing in the various commands. Using the command line to manage your Docker setup is pretty simple, but some people prefer a more visual user interface when managing their systems. Portainer gives you that visual interface.
When you visit a website, such as codeopolis.com your computer will contact your DNS provider and ask for the IP address of codeopolis.com so your computer can visit the site. The DNS provider will then log that request, creating a record of your visit. Can you trust that your DNS provider or Internet Service Provider (ISP) will not share or sell that information? I don’t.
Over the past few months, I’ve been working to transition to as many self-hosted applications as I can. Self-hosting applications is a secure way to control your data on your terms as well as to get it moved off of the public cloud.
Watchtower is an application within a docker container that watches for updates for all of the running containers on a system. If an update is available for any of the containers, then Watchtower will restart that container with the new image using the same parameters as the previously running image.
Internet advertisements and trackers are everywhere. The websites you visit and your smart devices are constantly sending data to their manufacturers and advertisers. Pi-hole is a network-level ad blocker that sits on your network and uses blacklists to determine which DNS requests to block. Installation on Docker is easy.
Heimdall is a quick and easy way to organize all of your applications and frequently visited links into one page. Personally, I have enabled the Google search bar and use this application as my browser start page. Once you add your application to the dashboard through its easy to use interface, you can drag and drop to move the buttons around as you see fit.
Theia is an open-source integrated development environment that is web based and can be self-hosted on any server and easy deployed via docker.

Theia supports multiple code languages and contains full featured integrated terminal.
Home Assistant is open-source, self-hosted software that will allow you to control various devices in your home. It is extremely flexible and can be used to tie together multiple sensors and services to create the ultimate smart home. As I continue to learn about the functionality of Home Assistant I’ll add more posts about setting up sensors and other devices.
Bitwarden is an open-source password manager that can be self-hosted at home to keep your passwords and other private data secure. The official Bitwarden image only supports the amd64 architecture and I needed a container that I could run on my Raspberry Pi 4 cluster. Luckily I found Bitwarden_rs which is not as resource intensive as the official image and is perfect for small self-hosted environments.
