v1.1.0

What's Changed

• Support for Cloud Run gen1 enabled using pinned versions of libpcap and tcpdump by @gchux in #19
  • see Feature Request: #18
• All Docker images are now labeled with versions of relevant dependencies: libpcap, tcpdump, and pcap-cli
  • see: https://github.com/gchux/cloud-run-tcpdump/pkgs/container/cloud-run-tcpdump
• pcap-cli is now at v1.0.0-rc113 introducing improvements for
  • SIGTERM handling
  • L4 analysis improvements for TCP options and endpoint analysis ( forward and backward )
  • L3 analysis improvements for endpoint analysis ( forward and backward )
  • HTTP improvements to better handle [ErrUnexpectedEOF] for both HTTP/1.1 and HTTP/2
  • improved Cloud Logging message summary to facilitate TCP sequence and acknowledgment analysis
  • fixed bug where using golang logger Fatal* was causing os.Exit thus preventing clean terminations

New Images

• Cloud Run gen2: ghcr.io/gchux/cloud-run-tcpdump:v1.1.0-gen2
  • alias: ghcr.io/gchux/cloud-run-tcpdump:newest
  • contains newest versions of libpcap (v1.10.5) and tcpdump (v4.99.5)
• Cloud Run gen1: ghcr.io/gchux/cloud-run-tcpdump:v1.1.0-gen1
  • alias: ghcr.io/gchux/cloud-run-tcpdump:latest
  • contains versions of libpcap (v1.8.1) and tcpdump (v4.9.3) that work with both Cloud Run gen1 and gen2

In general, most users should be OK using ghcr.io/gchux/cloud-run-tcpdump:latest;

if the latest versions of libpcap and tcpdump are required, use ghcr.io/gchux/cloud-run-tcpdump:newest instead.

NOTE: Cloud Run gen1 is not yet officially supported, but when the time comes, support is available since this release.
