You are insanely underrated, I feel so lucky that I stumbled upon your Hibernate Video and now I have some important topics you made videos about that I can explore thank you.
Your Quality and teaching is really good in comparison with many others on youtube, I hope the Algorithm does his Job better soon :D

Best practices for multi stage builds would be nice to see or if you like, what is the most difference of buildpacks vs. dockerfile for Java (e.b. Spring Boot) applications.

I got to know you from your blog where you explained how Spring transactions work. You are among the very few people who can convey an idea without any confusion to the reader/consumer.
Great work, Marco. Thank you for creating these materials. 🔥🔥

Excited to watch! I appreciate the condensed quality you provide!

Marko + Docker in one sentence? Sounds like a click bait for me)
It's nice to see you again!

RUN with mount parameter is awesome! 😍 I spent a lot of time fighting with copying deps which should be cached after build and it's my issue with multistage builds. Thanks! ♥

Thank you Marco.

Docker init is a great command too. It generates .dockerignore file and you can choose between different templates depending on your programming language.

We also can add a build with multi-stage builds, this will allow us to filter files, speed up build speed with a little image like Alpine or "slim" versions. :)

Another tips is that we should use the image which we need, like for ex, if we need to run a java application, we need to use an image which contains just JRE, and also we can clean this image from unused packages
