Docker has become one of the easiest ways to manage containerized apps on Linux, Mac and even Windows Machines. Personally, I use docker to self-host a ton of apps at home. I have it running on a couple of Raspberry Pi’s, as well as a windows machine. I wanted to share my installation experience.
Prior to installing Docker
Be sure to run sudo apt-get update and sudo apt-get upgrade.
Install Docker
Run the following command:
curl -sSL https://get.docker.com | sh
Permissions
You are going to want to add the proper permissions to your primary user account to easily run docker commands. To do that, run the following command:
sudo usermod -aG docker YOURUSER
Replace YOURUSER with the name of the user you are logged in as.
Reboot
Reboot your machine by running: sudo reboot.
Install Dependencies
To keep everything running smoothly, you’ll want to run the following commands to install the following dependencies:
sudo apt-get install libffi-dev libssl-dev
sudo apt-get install -y python python-pip
sudo apt-get remove python-configparser
Test
Docker should be running by this point. Running the following command should pull an image from the Docker Hub and display hello-world on your screen.
docker run hello-world
Install Docker Compose
For more advanced scenarios, you can install Docker Compose to allow you multiple containers that are dependent on each other with a single command:
sudo pip install docker-compose
Success!
Now that Docker is running you can explore the Docker Hub to find various containers to run. To get a basic knowledge of how to use Docker, you can read the 25 basic docker commands for beginners.
