This release of flannel contains many new features and improvements. Highlights include

  • A new IPIP backend.
  • A configuration for using Wireguard with the extensions backend.
  • Some build changes. All images are now based on Alpine Linux.
  • Initial groundwork for Windows support.
  • Some changes to how subnets are configured. Flannel now performs additional checks on the configuration options that users supply.
  • Changes to the kubernetes manifests
    • The CNI configuration is now specified as a .conflist which allows multiple plugins to be chained. If you are upgrading flannel by just applying the new manifest, then kubernetes will continue to use the old .conf instead of the new .conflist until you manually delete the .conf file. See discussion in #855 (comment) for more details.
    • The CNI configuration now includes the portmap plugin to provide hostPort functionality. You must ensure that the plugin is installed on your host (it will be if you have at least version 0.6.0 of the CNI plugins). This kubernetes manifest in this repo does not install any CNI binaries so you must install another way.
  • A number of other bug fixes and improvements. See below for the full list.
