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
