proxy: v2.183.0 (#8869)
This release updates the proxy to configure inbound route
configurations--including authorizations and filters--via discovery from
the control plane.

If the controller does not yet configure routes, the proxy uses a
default route. Route authorizations always extend the server's
authorizations, so routes need not be defined to admit traffic. However,
if a server have at least one route, *only* traffic that matches a route
will be permitted, otherwise requests fail with a 404.

If the proxy receives a router filter of an unknown type (i.e., because
the controller is running a later version of the API that includes new
types), then the proxy will FAIL all requests on that route with an
internal server error. It's considered safer to fail hard in this case,
rather than to silently ignore a configured policy that could
potentially be security-sensitive.

🎈 Welcome to Linkerd! 👋

Linkerd is an ultralight, security-first service mesh for Kubernetes. Linkerd adds critical security, observability, and reliability features to your Kubernetes stack with no code change required.

Linkerd is a Cloud Native Computing Foundation (CNCF) project.

Repo layout

This is the primary repo for the Linkerd 2.x line of development.

The complete list of Linkerd repos is:

Quickstart and documentation

You can run Linkerd on any modern Kubernetes cluster in a matter of seconds. See the Linkerd Getting Started Guide for how.

For more comprehensive documentation, start with the Linkerd docs. (The doc source code is available in the website repo.)

Working in this repo

BUILD.md includes general information on how to work in this repo.

We ❤️ pull requests! See CONTRIBUTING.md for info on contributing changes.

Get involved

Community meetings

We host regular online meetings for contributors, adopters, maintainers, and anyone else interested to connect in a synchronous fashion. These meetings usually take place the last Thursday of the month at 9am Pacific / 4pm UTC.

We're a friendly group, so please feel free to join us!

Steering Committee meetings

We host regular online meetings for the Linkerd Steering Committee. All are welcome to attend, but audio and video participation is limited to Steering Committee members and maintainers. These meetings are currently scheduled on an ad-hoc basis and announced on the linkerd-users mailing list.

Code of Conduct

This project is for everyone. We ask that our users and contributors take a few minutes to review our Code of Conduct.

Security

See SECURITY.md for our security policy, including how to report vulnerabilities.

A third party security audit was performed by Cure53 in June 2019. You can see the full report here.
