• code
• runtime
• system tools
• system libraries

And much more you can Install on a Linux server. The main specification of Docker is that it can work in any Environment.

Lets proceed with the Installation process.

Step 1: Update your System

Make sure that your system is up-to date.

sudo apt -y update

Step 2: Install Basic Dependencies

We need few dependencies for our actual Installation of Docker, so we will configure these. Install them by running the given command in your Terminal.

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

Step 3: Installing Docker CE on Ubuntu 16.04 / 18.04 / 19.04

If you’re using any previous version of Docker remove them.

sudo apt remove docker docker-engine docker.io containerd runc

Now, import GPG key.

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

After it, add Docker CE repository to Ubuntu.

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

Final step is to Install Docker CE on Ubuntu 16.04 / 18.04 /19.04

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

Now, add your user account to docker group

sudo usermod -aG docker $user
newgrp docker

Check Docker Version to Verify your Installation.
