Installing Docker Engine From Your Repository

With our Docker Repository all set up, use the following command to update.

sudo apt-get update

If you get a GPG error when trying to run the previous command, use this command to fix it before re-trying the update.

sudo chmod a+r /etc/apt/keyrings/docker.gpg

Now we're ready to install Docker. Use the following command to do so:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y

After the installation process is complete, confirm that Docker installed properly by testing this hello-world function.

sudo docker run hello-world

When you see this screen, you'll have completed these steps successfully.

Congratulations! In the next lesson, we'll properly configure Docker for our use case of running Bitwarden Unified.

For more information on this installation procedure, you can refer to Docker's Official Documentation For Installing Docker Engine.
