The hardcoded 1-hour lease expiration in nerdctl container commit can cause failures for containers with large filesystem deltas (e.g., many packages installed). When the diff.Compare operation exceeds 1 hour, the containerd GC cleans up the expired lease and its ingest data, resulting in 'context deadline exceeded' errors. Changes: - Add Timeout field to ContainerCommitOptions and commit.Opts - Modify Commit() to use configurable lease expiration: * --timeout=0 (or negative): use containerd's default 24h lease * --timeout>0: use the specified duration * --timeout defaults to 1h for backward compatibility - Add --timeout CLI flag (default: 1h) - Add tests for --timeout flag Usage: nerdctl container commit mycontainer myimage:tag # default 1h nerdctl container commit --timeout=4h ... # 4h timeout nerdctl container commit --timeout=0 ... # 24h (containerd default) Signed-off-by: Turbo Jia <turbo@example.com>

--timeout=0 creates a lease that never expires. containerd's client.WithLease only applies the 24h default when no opts are passed at all:

The hardcoded 1-hour lease expiration in nerdctl container commit can cause failures for containers with large filesystem deltas (e.g., many packages installed). When the diff.Compare operation exceeds 1 hour, the containerd GC cleans up the expired lease and its ingest data, resulting in 'context deadline exceeded' errors.
