00:00Have you ever heard of Docker and wondered,
00:02what is Docker and why is everyone talking about it?
00:06Docker is a platform that makes it easier to develop,
00:10deploy, and run applications by using something called containers.
00:14But what exactly is a container?
00:16Think of it like a lightweight,
00:18portable box that holds everything your application needs to run,
00:22like code, tools, libraries, and settings.
00:26Before Docker, developers frequently ran into issues like,
00:30it works on my machine but not on yours.
00:33This was due to different environments could have
00:36different settings, dependencies, or software versions.
00:39Docker solves this by using containers,
00:41which are isolated environments that ensure
00:44your app runs exactly the same everywhere.
00:46Apart from that, Docker offers key benefits like efficiency and speed.
00:52It shares the host operating systems kernel and uses
00:55fewer resources than traditional virtual machines,
00:57and containers are fast to build,
01:00deploy, and start, ideal for agile development and scaling.
01:04Do you wonder how Docker works?
01:06We use a file called Dockerfile,
01:09which is a simple text file with
01:10instructions for building your application environment.
01:13This file is used to create a Docker image,
01:16a snapshot of your application and all its dependencies.
01:19You can think of the image as a blueprint.
01:22Finally, you run this image as a Docker container,
01:25which is your application running in a contained environment.
01:28Let's say you built an app on a specific Linux distribution.
01:32With Docker, you can package this app
01:34with all its dependencies into a container.
01:37Now, you can easily share this container with anyone,
01:40and they can run it flawlessly on their machine,
01:43even if they have a completely different setup.
01:45You can get our Docker cheat sheet,
01:47which has all Docker commands.
