Docker lab setup on Ubuntu 22.04 Server LTS

Setting up docker on Ubuntu 22.04 Server 

First, update your existing list of packages

sudo apt update

Install a few prerequisite packages which let apt use packages over HTTPS:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Add the GPG key for the official Docker repository to your system

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add the Docker repository to APT sources:

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update your existing list of packages

sudo apt update

Make sure docker-ce install from default repo

apt-cache policy docker-ce

sudo apt install docker-ce docker-ce-cli containerd.io

Check that it’s running:

sudo systemctl status docker

Execute command without sudo

sudo usermod -aG docker ${USER}

su - ${USER}

groups

Check the docker command

docker
