Docker installation on Linux Mint 18.3

Official documentation on docker site has mistakes, below steps will wnsure docker will be installed properly on your Linux Mint machine. Additionaly you won't be needing to call sudo everytime using docker.

1. execute below commands:

   # import PGP key
    
   sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 \
   --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
    
   # add official repository to package manager 
    
   sudo apt-add-repository 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'
    
   # update packages
    
   sudo apt update
   
   # install dependencies
    
   sudo apt install linux-image-generic linux-image-extra-virtual
    
   # Reboot
    
   sudo reboot
   
   # Install Docker
    
   sudo apt install docker-engine
   

2. Change settings to use docker without sudo
   https://docs.docker.com/install/linux/linux-postinstall/#manage-docker-as-a-non-root-user

   sudo groupadd docker
   sudo usermod -aG docker $USER

   Now you should be able to use docker without sudo. Run example to check correctness of installation: docker run hello-world
