+A quick guide to getting docker running on a Debian CT
+
+<!--more-->
+
+## CT Configuration
+
+First make sure your container is running in privledged mode and nested is enabled in Options > Features
+
+![features](/assets/img/lxc-docker-setup-1.png)
+
+## Installing Docker
+
+Then you'll need to login and install docker.
+
+```bash
+sudo apt install docker.io -y && sudo systemctl enable docker
+```
+
+Then start and confirm the service
+
+```bash
+sudo systemctl start docker && sudo systemctl status docker
+```
+
+To ensure Docker is running correctly you can try to run a simple hello-world container
+
+```bash
+sudo docker run hello-world
+```
+
+## Install Docker Compose
+
+Debian unfortunately only ships with docker compose v1. The plugin for v2 needs to be installed manually from github releases. Keep in mind the version number can be whatever is the latest (v2.14.2 as of this post).
+
+```bash
+mkdir -p ~/.docker/cli-plugins
+```
+
+```bash
+curl -sSL https://github.com/docker/compose/releases/download/v2.14.2/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
+```
+
+```bash
+chmod +x ~/.docker/cli-plugins/docker-compose
+```
+
+Now check to make sure v2 is installed
+
+```bash
+docker compose version
+# Docker Compose version 2.14.2
+```
+
+## Run Docker from a non-root user without sudo
+
+```bash
+sudo usermod -aG docker $USER
+```
