Release 1.3.1

Summary

Pumba 1.3.1 removes iptables rules left behind when pumba iptables fails partway through installing them.

Changes

• Partial iptables installs are rolled back. pumba iptables installs one rule per --source, --destination, --src-port and --dst-port value and stops at the first rule that fails. In 1.3.0 and earlier, the rules installed before that failure stayed in the target container's INPUT chain with no timer, and dropped traffic until the container restarted. Pumba now runs the same cleanup it runs at the end of --duration and returns the original error. Cleanup runs even if Pumba is stopped mid-install. This applies to the Docker, containerd and podman runtimes. A failed cleanup is logged as a warning. (#376)
