I don't think there is a Kubernetes lecture as good as this one on Inflearn. [A word to those who want to take the lecture] I looked into why there are so many stars instead of 5. There were many criticisms about the sound and settings. But honestly, the essence of the lecture is Kubernetes. The sound part may be lacking unless you are a professional instructor, but it is not to the point where you cannot take the lecture. The content alone is enough to make the lecture less than 5 stars. Honestly, I would like to ask those who gave low ratings. Do I have to teach you everything? It is a lecture that costs around 50,000 won. Environment settings? Try to find the reference page and install it once.... If you are really ready to study, shouldn't you be enthusiastic enough to listen to the lecture with the Kubernetes dashboard and review it once more with the CLI? Those who pointed out environment settings, if I were the leader of the development organization, I would never choose them;; [A word to the instructor] Instructor, this lecture was full of efforts to provide a good lecture. In fact, it seems that the content up to the intermediate level is enough to handle almost all situations in an organization that is just starting to introduce Kubernetes. However, it seems that you are hurt by the bad reviews because you worked too hard to create the lecture. Please don't worry too much and I hope you will continue to provide good lectures.
