Today we are going to learn you that how you can Install Docker engine on your Ubuntu system. Docker engine allows you to package your applications with all of its dependencies into a single standardized unit for software development & distribution.
It is an open source Linux Distribution which wrap up a piece of software in complete file system that contain everything it needs to run like:
- 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.
