Fascinating deep dive into OverlayFS CoW behavior. The 11GB btmp file getting copied 271 times is a perfect storm scenario. Did they consider mounting /var/log outside the image layers? Seems like that would prevent any log file from causing this amplification. Also interested in image-manip... Does it handle metadata differently than
docker export/import?
- hug 11mo agoIs it fascinating? Do people not know that each layer comes with its own downsides? Do people just do 272 layers and think that it’s normal? This seems like people discovering that water is wet and fire is hot.

- macNchz 11mo agoSeriously. Honestly this whole thing feels kinda like…using an LLM to write a blog post about debugging weird problems that only exist because the whole platform was built by an LLM in the first place. The multiple top level comments that are clearly written by an LLM are icing on the (layer) cake.
- ndsipa_pomu 11mo agoThis is less of a deep dive and more an illustration of the worst way to use containers. Having /var/log set as as a persistent volume would have worked, but ultimately they were using "docker commit" to amend/update their images which is definitely the wrong way to do it.
