This release brings a number of bug fixes:

  • An important update to the GoBGP library that fixes a leaking socket bug.
    • If you've experienced degraded performance or failures over time with a kube-router powered cluster, this release should fix those issues.

Also included are a number of enhancements:

  • Automatic Pod CIDR detection
    • --cluster-cidr flag is no longer needed for pod egress
    • Use --enable-pod-egress=false to disallow pod egress traffic outside the cluster
  • Streamlined kubeadm integration
  • ipip tunneling performance improvements between nodes in different networks.

DaemonSet Upgrade Steps

image: cloudnativelabs/kube-router[:latest]

imagePullPolicy: Always

These are the default options in our manifests. In this scenario you just need to delete the pods so they are recreated. This will not interrupt cluster services/traffic.

kubectl -n kube-system delete pods -l k8s-app=kube-router

image: cloudnativelabs/kube-router:vX.X.X

If your image option is pinned to a specific version, you can upgrade using kubectl set image.

kubectl -n kube-system set image ds/kube-router kube-router=cloudnativelabs/kube-router:v0.0.12
kubectl -n kube-system delete pods -l k8s-app=kube-router
