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. 🔥🔥

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.

@KevinSheppard 11 күн бұрын

I'd like to second this. I haven't had much luck understanding buildpacks.

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! ♥

This part of the video blew my mind as well. I have some builds that take quite some time because of npm install.

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.

Good tip!

"multi stage build" and "creating non-root user for the container" next please

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

Bear in mind, like mentioned in the video, that cleaning packages does not influence the previous layers.
