edge-20.7.2
This edge release moves Linkerd's bundled Prometheus into an add-on. This makes
the Linkerd Prometheus more configurable, gives it a separate upgrade lifecycle
from the rest of the control plane, and will allow users to disable the bundled
Prometheus instance. In addition, this release includes fixes for several
issues, including a regression where the proxy would fail to report OpenCensus
spans.
- Prometheus is now an optional add-on, enabled by default
- Custom tolerations can now be specified for control plane resources when
installing with Helm (thanks @DesmondH0!) - Evicted data plane pods are no longer considered to be failed by
linkerd check --proxy, fixing an issue where the check would be retried
indefinitely as long as evicted pods are present - Fixed a regression where proxy spans were not reported to OpenCensus
- Fixed a bug where the proxy injector would fail to render skipped port lists
when installed with Helm - Internal improvements to the proxy for lower latencies under high concurrency
- Thanks to @Hellcatlk and @surajssd for adding new unit tests and spelling
fixes!
