Release 2.1.1

As 2.1.0, but fixing a couple of installation glitches - #3175,#3176

New Features

Improved Kubernetes Network Policy - Weave Net now supports the 'v1' policies introduced in Kubernetes 1.7 as well as the 'beta' policies supported previously. See Kubernetes 1.7 changelog for differences. To use old policies, --use-legacy-netpol argument should be passed to weave-npc. #3105,#3141,#3151,#3169

Weave Net now reclaims IP addresses owned by Kubernetes nodes which have been deleted from the cluster - this avoids running out of IP addresses when many nodes are added and deleted over a long period. #2797,#3149,#3170,#3172

Upgrading the Weave Net Kubernetes addon (weave-kube)

There is an updated DaemonSet manifest for Kubernetes 1.7 and 1.8 that adds an access to networkpolicies from the networking.k8s.io API group used by the 'v1' policies and a new role to create ConfigMaps:

kubectl apply -f https://cloud.weave.works/k8s/v1.7/net

To use old network policies:

kubectl apply -f https://cloud.weave.works/k8s/v1.7/net?use-legacy-netpol=true

Other improvements

  • Export a Prometheus-style metric giving count of unreachable peers #3119
  • Update 'gopacket' library to reduce memory use by approx 15MB #3160
  • Replace bundling the 'docker' binary with our own code to avoid security vulnerability alerts and save space #2957,#3110

Bug fixes

  • When weave expose is used, allow traffic into the Weave network - up till version 1.12 Docker would do this for us, but in 1.13 they stopped so now we do it. This change makes weave expose to require Weave Net to be running. #2758,#3122
  • Arm64 build now works on non-kubernetes installs #2832,#3110
  • TX offload was being disabled in 'awsvpc' mode, which slows down packet sending #3089
  • Removed spurious 'nil' in logs from CNI DEL operation #3143

Build and test

  • Images are now also built for the ppc64le platform #3129
  • Tweak build scripts to run on OSX as well as Linux #3135
