== 1. How Docker Works == Docker simplifies running software by packaging everything the software needs into one neat bundle. It does this using '''containers''' which are lightweight standalone environments that share the host system’s resources but remain isolated. This is like a virtual machine, but without the baggage of needing its own operating system. Docker containers run on a shared kernel, making them much faster and lighter. If you ever enter a docker container, you will notice that almost no programs or commands are available besides the ''bare minimum'' necessary to do the job. See below: <pre>louis@ultimatebauer:~$ docker exec -it frigate bash root@174eb3845d50:/opt/frigate# nano file.log bash: nano: command not found root@174eb3845d50:/opt/frigate# vi file.log bash: vi: command not found root@174eb3845d50:/opt/frigate# vim file.log bash: vim: command not found root@174eb3845d50:/opt/frigate# emacs file.log bash: emacs: command not found root@174eb3845d50:/opt/frigate# ip addr show bash: ip: command not found root@174eb3845d50:/opt/frigate# you really don't have shit in here besides exactly what you need to run the application, do you? run nano you prick!</pre> <blockquote>root@174eb3845d50:/opt/frigate '''I’m afraid I can’t do that, dave''' </blockquote> <span id="what-are-docker-images"></span>
