Bug fixes and minor improvements

  • Fix a race condition when the Weave Net container is restarted
    which could allow a new container to be allocated the same IP
    address as an existing one #2784,#2787
  • Handle the message type received when a pod has been deleted during
    Kubernetes api-server fail-over #2772,#2773
  • Make weave-kube work with dockerd --iptables=false #2726
  • Ensure we have the right kernel modules loaded for Network Policy in weave-kube #2819
  • Reference-count addresses in Network Policy Controller, to avoid
    errors when updates come in an unexpected order #2792,#2795
  • Allow the soft connection limit to be raised in weave-kube, so
    larger clusters can be created #2781
  • WeaveDNS was incorrectly case-sensitive for reverse DNS lookups #2817,#2818

Build and Testing

  • Scripts to create VMs to run automated tests were rewritten to use
    Terraform and Ansible, to make it much easier to test with different
    versions of components such as Docker and Kubernetes #2647,#2694,#2775,#2796
  • Upgrade to latest Weaveworks common build-tools #2780
  • Improve encryption tests #2793
  • Update vishvananda/netlink library to bring in changes we had previously forked #2790
  • Slight change to the build container to avoid permission errors and slow builds #2761,#2802

Installation and Upgrading

Follow the installation instructions to install this latest release of weave.

If your host's network interface has a limit on packet size (the "MTU") smaller than 1496 bytes, you should reboot after upgrading to ensure encrypted fast datapath can work. For instance this applies to Google Cloud Platform, but is not necessary on AWS.

Weave Net 1.9.1 is fully compatible with all previous versions back to 1.1.0, so it is possible to upgrade clusters incrementally and run mixed versions.

Upgrading the Weave Net Kubernetes addon (weave-kube)

Kubernetes does not currently support rolling upgrades of daemon sets, so you will need to perform the procedure manually - see https://weave.works/docs/net/latest/kube-addon/ for details.

NOTE: The mount points for host directories moved in version 1.9.0, and were extended in 1.9.1. If you are running a modified version of the DaemonSet specification, please update it to match the new release.
