From the quality of the lecture materials... This seems like a really great lecture, but since there is no such thing as a free lunch, I hope you know that you have to dig deep and work hard to improve your skills. As someone who thinks that basic network knowledge, Linux, and container understanding are necessary before starting k8s, I hope that this will be a time to ask yourself if your basics are sufficient and look back on whether you have the perseverance to find and solve errors on your own before starting k8s. When I first installed it, there were a lot of errors because the host environment was different. All Kubernetes lectures proceed with the installation using Vagrant scripts in a Windows VM environment, but I really didn't like this. If you depend on someone else's script and proceed without properly understanding the contents of the script, you feel like you missed something and it feels like you're floating around, and you don't study properly. In reality, it takes a lot of time to build the infrastructure environment yourself, so there's nothing you can do about it, but anyway, that's why I didn't rely on Vagrant in the first place, and I'm building the same environment with my own infrastructure by writing all the scripts. As I learned by building my own VM infrastructure environment without relying on Vagrant, it was a good opportunity to look back on Linux and networks, and it was a good learning experience. I think that I have to experience everything manually, from the installation environment to the operation, to make it truly mine. Thank you for the quality lecture, and I look forward to the next lecture.
