docker ubuntu error

    After install docker maybe need using docker without sudo for home users.
  
  
    

  
  
        Fact : for security don't bypass sudo request in docker.
  
  
    

  
  
    Step 1
  
  
    Create docker group if not exist : sudo groupadd docker
  
  
    

  
  
    Step 2
  
  
    Add user to docker group : sudo usermod -aG docker ${USER}
  
  
    

  
  
    Step 3
  
  
    Change docker.sock to new permission : sudo chmod 666 /var/run/docker.sock
  
  
    

  
  
    Step 4
  
  
    Finally restart docker daemon service : sudo systemctl restart docker
