Today I learned about OCI stuff (that is totally new to me) and what’s going on behinds the scene when I run docker build. At first I thought it was a complex, custom-made, Docker-specific stuff. The way you broke it down two ordinary Linux commands made it much clearer for me what’s going on… it doesn’t look as scary as I thought now.

Thanks for sharing!
