FATA[0000] lstat /Containerfile: no such file or directory #4285

Description

Using nerdctl (from Rancher Desktop v 1.18.2) to build a container doesn't find the local Dockerfile and seems to want a Containerfile at the root of the filesystem, not the current path.

Build succeeds using Git Bash on the same machine using the same command, so for now I context switch from rancher-desktop WSL to git bash to build and then back to rancher-desktop WSL to run.

Steps to reproduce the issue

  1. ls -al Dockerfile
    -rw-rw-rw- 1 root 0 151 May 23 06:33 Dockerfile
  2. nerdctl build -t db:20250523 .
    FATA[0000] lstat /Containerfile: no such file or directory
  3. pwd
    /mnt/c/Users/myuser/Documents/projects/couchdb
