Docker Getting Started/Practical Guide That Even Non-Majors Can Understand

🤬 Damn it, I can't do this anymore!

I'm Park Jaesung, who started development as a non-major and worked as a CTO at various companies, and am currently working as an educator. I also started development as a non-major and had times when I was deploying servers and studying Docker.

The first feeling I had when studying Docker was 'vastness and frustration'.

I was planning to buy a Docker-related book to study and learn Docker. The book was structured in a way that explained Docker commands one by one. There were so many commands that it felt overwhelming to learn. However, I persevered and studied the commands one by one.

While my understanding of each command has improved, I couldn't get a feel for how to apply this in real-world situations at all. Even though I studied with a Docker book for a month, I felt frustrated seeing myself unable to apply it to actual projects.

Having experienced such difficulties myself, I thought I should create a Docker course that non-majors can easily understand and apply directly in real-world situations.

✨ 4 Key Points I Focused on While Creating the Course

👍 Great for these types of people!

🙊 What happens after you finish listening to this entire lecture?

✔ Reference Notes

If you know basic Linux commands, you'll be able to take the course much more easily. However, even if you don't know basic Linux commands, you can definitely learn by utilizing the 'comment study method' that I'll explain in the course. Also, for those who have no experience deploying servers with AWS, I've added supplementary AWS lectures. If you come across any parts you don't understand while studying, please feel free to ask questions right away using the Q&A board or 1:1 open chat room😊

🚨 Make sure to check what kind of person is providing the education!

If you meet the wrong doctor, you might face death because your illness can't be cured at that moment. But death ends with the pain of that moment. However, if you meet the wrong teacher and receive poor education, you will suffer throughout your entire life.

Wrong education can lead you to an unwanted company, receive a smaller salary than expected, and potentially suffer for the rest of your life. Not only that, but the wrong education you received can also be passed down to your children as a legacy of poor education.

Education can truly change a person's life in a positive way, but on the other hand, it can also completely ruin a person's life. That's why I believe education carries such heavy responsibility.

Therefore, please check who is providing the education, what kind of person they are, and what path they have walked, and make a careful judgment.

👋 Hello!
I'm finally introducing myself now ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

Hello!

I started studying development as a non-major. Before I knew it, I've already become a 6-year developer! Recently, I worked as a developer while serving as CTO at two companies. Whenever I had time, I've been doing coding lectures, company development consulting, and giving talks.

The number of students I've taught has now exceeded 24,000 (as of July 2025)! Every time I teach my various students, I always feel the same way - I can't forget the sense of fulfillment from education, so I plan to continue providing education consistently on Inflearn.
(* Among students, successful candidates for Kakao Pay, Yanolja, and Woowa Brothers have been produced)

Just as I received a lot of help during difficult and challenging times, I wanted to become someone who could help many other people as well. And I felt most proud and happy when the value I created through development had a positive impact on others.

For these reasons, I hope that by giving and sharing what I have worked hard to achieve, those people can live slightly better lives.

Thank you!
