Please use Docker!

More than 58% of developers
We're already using Docker in production.

Current status of Docker 🐳

Since its release in 2014, Docker has grown steadily and established itself as a standard for container environments.

According to statistics released by Docker in 2016, 58% of developers said they use Docker in their production environments .

This is a truly staggering figure. The production environment holds immense significance for any service. Any issues with production can negatively impact the company's bottom line. Therefore, every company builds its production environment using proven, proven tools that have proven themselves over time and are stable .

Docker's influence is evident when you consider that 58% of users are using the product in production, barely two years after its 1.0 release.

Recommended for these people! 🌭

$ docker build ...
$ docker run ...

👆For those who know how to use this command but still don't know why they use Docker,
Or I don't even know that command... Of course, I recommend it to those who do!

What will you learn? 🤷🏼‍♀️

What's the point of learning something just because others are using it? In this course, let's learn the reasons for using Docker and its philosophy .

Next, let's get hands-on. Let's build an image and create a container to get our hands dirty with Docker.

You'll also have the opportunity to explore various options used in container runtimes (port binding, volumes), as well as Nginx, MongoDB, and Redis ! For more information, check out the 👉🏻 [Curriculum] !

Honey Tip 🏠

The real reason to use Docker will be revealed in the latter half of the lecture, so please make sure to watch it until the end. 🍉

The reason I reveal the reason at the end is because it's difficult to empathize and understand without a basic understanding of Docker. If you follow along carefully from the beginning of the lecture, you'll be thrilled when you hear the real reason for using Docker : "Ah, so that's why!"

Do I need to prepare anything else? 🏏

Windows : Requires 64-bit Windows 7 or later.
Mac : Requires a 2010 model or later, macOS 10.13 or later, and 4GB or more of memory.
Ubuntu : Compatible with the versions below and requires a 64-bit environment.

• Disco 19.04
• Cosmic 18.10
• Bionic 18.04 (LTS)
• Xenial 16.04 (LTS)

You can use any source code editor you're familiar with. Notepad is fine as long as you can edit text.

We'll use shell commands in class, but you don't need to know them in detail. This course focuses solely on Docker , so you don't need to understand how the code we write works. The code or commands we write are simply used to explain Docker .
