nerdctl system df reports disk usage

Introduced 2026-09-20 · score 0.96

HOW TO USE IT

When inspecting nerdctl-managed disk usage, run `nerdctl system df` for the current namespace. Add `--verbose` (`-v`) for detailed space usage or `--format <format>` to format the output.

nerdctl system df
nerdctl system df --verbose
nerdctl system df --format 'table {{.Type}}\t{{.Size}}'

WHY THIS HELPS

Inspect disk usage for nerdctl-managed resources while maintaining a development environment.

REQUIREMENTS AND LIMITATIONS

  • Version: v2.4.0
  • --verbose, -v: Show detailed information on space usage.
  • --format <format>: Format output with a Go template; `table` prints default columns, while `table TEMPLATE` prints template columns with a header and alignment.
  • Prerequisite: nerdctl v2.4.0 is expected to be used with containerd v1.7 or later; some features may not work with other containerd releases.
