Docker Service Failure

General
1

Using the docker Service inside firebase studio to host the Apache Polaris image is throwing this error message: "failed to register layer: Lsetxattr user.overlay.impure /etc: operation not supported.

  • Lsetxattr: This refers to the lsetxattr() system call, which is used to set extended attributes on a file or directory. Extended attributes are metadata associated with files beyond the usual permissions, timestamps, etc.
  • user.overlay.impure: This is a specific extended attribute that Docker uses, particularly when employing the overlay2 storage driver (which is the default and recommended driver for many Docker installations). It’s related to how Docker manages layers of images and containers.
  • /etc: This is a critical directory in Linux systems, containing system-wide configuration files.
  • operation not supported: This is the core of the problem. It means that the underlying filesystem or kernel where Docker is trying to perform this operation (setting the user.overlay.impure extended attribute on a file within /etc) does not support it.

How to resolve it in firebase studio? @kirupa

Thanks

Hi Nelson.

I’m not particularly familiar with this syscall but happy to take a look. In general, we can only support rootless docker and rootless docker doesn’t seem to support Lsetxattr

Can you help me with repro steps? Is it correct to assume that you see this issue when pulling from the polaris image? Trying to see if there’s a workaround
