edge-21.6.2
This release fixes a problem with the HTTP body buffering that was added
to support gRPC retries. Now, only requests with a retry configuration
are buffered (and only when their bodies are less than 64KB).
Additionally, an issue with the outbound ingress-mode proxy where forwarded
HTTP clients could fail to detect when the target pod was deleted, causing
connections to retry forever has been fixed. This only impacted traffic
forwarded directly to pod IPs and not load balanced services.
Finally, this release also includes some fixes in the CLI and dashboard.
- Added a new check that verifies if the opaque ports annotation is
misconfigured on services or pods (thanks @migue!) - Added support for resource aware completion for core linkerd command
- Fixed an issue where
namespaceresource was erroneously being shown
in the dashboard's topology graph - Added uninstall command support for legacy extension installs
- Updated the proxy to only buffer request bodies when a request can be retried
- Updated the proxy to prevent buffering indefinitely on requests
when endpoints are updated in ingress mode - Fixed spelling mistakes across various files in the project
(thanks @jsoref!)
