Weave 2.2.1

Release 2.2.1

Bug fixes

• Fix a bug in weave-npc which would allow ingress traffic to Kubernetes Pods selected by a NetworkPolicy in which source and destination selectors were the same #3222,#3237
• Fix a bug in weave-npc which would crash if a previously deleted Kubernetes Namespace has been created again #3247,#3250

Other improvements

• Increase the default connection limit for Weave peers (from 30 to 100), so that more peers could directly connect #3234
• When doing a rolling update of Weave Net on Kubernetes, allow each node five seconds to initialize before rolling next Weave Net Pod, so that issues at startup will halt the rollout and not spread across the whole cluster #3235
• Install common CA certificates from Alpine Linux package instead of copying them manually #3236

Upgrading the Weave Net Kubernetes addon (weave-kube)

Apply the latest DaemonSet manifest, either attached to this release or from the config generator at Weave Cloud:

kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
