Manage Docker as a non-root user

The Docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The Docker daemon always runs as the root user.

If you don’t want to preface the docker command with sudo, create a Unix group called docker and add users to it. When the Docker daemon starts, it creates a Unix socket accessible by members of the docker group.

Warning: The docker group grants privileges equivalent to the root user. For details on how this impacts security in your system, see Docker Daemon Attack Surface.

Note: To run Docker without root privileges, see Run the Docker daemon as a non-root user (Rootless mode) .

• mkinitramfs or a tool to build a new initramfs
• some linux knowledge
• no need to create an image
• no need for Grub4Dos

var Vector = function(x, y) {
  this.x = x || 0;

};

// return the angle of the vector in radians
Vector.prototype.getDirection = function() {
	return Math.atan2(this.y, this.x);
};
