Description

It would be great if a container could be limited in how much storage space it could use in its rootfs. Something like

"name": "storage-space",
"limit": "500MB"

Open Questions

  • How would this be implemented in Linux?
  • What would the effect be of going over limit? Killing the app?

Contributor guide

Research direction
Investigate how to implement storage space limits in Linux containers, including using filesystem quotas (e.g., xfs quota) or overlayfs size limits. Study existing implementations in Docker or runc. Determine the behavior when limit is exceeded (e.g., kill app or block writes).
