Questions tagged [envoyproxy]

Use this tag for questions about the Envoy xDS APIs or Envoy internals.

Envoy is an L7 proxy and communication bus designed for large modern service oriented architectures. The project was born out of the belief that:

The network should be transparent to applications. When network and application problems do occur it should be easy to determine the source of the problem.

Envoy is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Envoy plays a role, read the CNCF announcement.

For official documentation, head to https://www.envoyproxy.io/

To get in touch with the envoy community, please see the contacts list.
