- File iperf3/Containerfile — part of check-in [bbab9c0693] at 2025-01-24 11:30:16 on branch trunk — Renamed iperf3/Dockerfile to Containerfile. (user: tangent size: 533)
- File iperf3/Dockerfile — part of check-in [6008e8f3d4] at 2024-07-06 15:22:18 on branch trunk — Added an empty /tmp to the iperf3 image for the benefit of container engines that don't provide it on instantiation. Resolves the unhelpful "iperf3: error - unable to create a new stream: Bad file descriptor" error due to iperf3's method of creating a background mmap'd file under /tmp for use in the test.
