on GitHub

Release 2.7.0

This release improves resiliency in a number of areas, and extends the Prometheus metrics exported by Weave Net.

Change in behaviour: on Kubernetes, the client source IP is preserved when calling from a pod to a service.
This feature, introduced in version 2.4.0 and previously turned on by setting NO_MASQ_LOCAL=1 is now on by default. #3389, #3756

Features

• Reload router iptables rules if they get cleared, e.g. when firewalld restarts. #3802 (weave-npc rules are not reloaded)
• Add new type and encryption labels to weave_connections metric #3788, #3789
• Weave Net now exports Go metrics for heap size, garbage collection, etc. #3838
• Register container name and its network aliases with weaveDNS #3084, #3090
• Make DNS listen address configurable #1770, #3231

Bug fixes

• weave-npc could crash if you deleted a Kubernetes Namespace containing pods #3833, #3836
• Ensure that weave-npc exits and restarts if it crashes #3764, #3792, #3841
• Avoid weave-kube failing on startup due to iptables lock #3828, #3835

Build and test

• Reduce size of containers (weaveworks/weave goes from 99MB to 83MB) #3624, #3726
• Weave Net is now built with Go 1.14.4, which should improve performance #3838
• CI tests are now run against Docker 19.03.1, Kubernetes 1.14.0 #3687
