edge-20.9.1
This edge release contains an important proxy update that allows linkerd to
continue to operate normally in HA during node outages. We're also adding full
Kubernetes 1.19 support!
- Improved the proxy's error handling for DNS errors encountered when
discovering control plane addresses, which can be common during installation,
before all components have been started - The destination and identity services had to be made headless in order to
support that new controller discovery (which now can leverage SRV records) - Use SAN fields when generating the linkerd webhook configs; this completes the
Kubernetes 1.19 support which enforces them - Fixed
linkerd checkfor multicluster that was spuriously claiming the
absence of some resources - Improved the injection test cleanup (thanks @zhouhao3!)
- Added ability to run the integration test suite using a cluster in an ARM
architecture (thanks @aliariff!)
