00:00:00 But why should we bother using Docker at all?
00:00:04 Big shots like eBay, Spotify, Washington Post, Yelp, and Uber noticed that using Docker made their apps better and faster in terms of both development
00:00:16 and deployment.
00:00:17 Uber, for example, said in their study that Docker helped them onboard new developers in minutes instead of weeks.
00:00:25 So what are some of the most common things that Docker helps with?
00:00:30 First of all, consistency across environments.
00:00:34 Docker ensures that our app runs the same on my computer, your computer, and your boss's computer.
00:00:41 No more, it works on my machine, Drama.
00:00:44 It also means everyone uses the same commands to run the app, no matter what computer they're using.
00:00:51 Since downloading services like Node.js isn't the same on Linux, Windows, or macOS, developers usually have to deal with different operating systems.
00:01:01 Docker takes care of all of that for us.
00:01:04 This keeps everyone on the same page, reduces confusion, and boosts collaboration, making our app development and deployment faster.
00:01:14 The second thing is isolation.
00:01:16 Docker maintains a clear boundary between our app and its dependencies.
00:01:21 So we'll have no more clashes between applications, much like neatly partitioned lunchbox compartments for veggies, fruits,
00:01:28 and bread.
00:01:29 This improves security, simplifies debugging, and makes the development process smoother.
00:01:36 Next thing is portability.
00:01:38 Docker lets us easily move our applications between different stages, like from development to testing or testing to production.
00:01:45 It's like packaging your app in a lunchbox that can be moved around without any hassle.
00:01:51 Docker containers are also lightweight and share the host system.
