Install Docker on Ubuntu/Debian


Install some prerequisites:

apt-get update
apt-get install apt-transport-https ca-certificates curl software-properties-common

Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add the repository:

add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

Install Docker:

apt-get update
apt-get install docker-ce

Try “docker info”, “docker version” or “docker ps -a” to check, once it’s installed.
