Please make sure you have the REGISTRY and PROJECT_ID environment variables set. For local builds these can be set to anything. For image builds these determine the location of your image. For GCE the registry should be gcr.io and PROJECT_ID should be the project you want to use the images in.
Proto definitions are compiled with protoc
. Please ensure you have protoc installed (Instructions) and the proto-gen-go
library at the appropriate version.
Currently we are using proto-gen-go@v1.3.2
go get github.com/golang/protobuf/protoc-gen-go@v1.3.2

The current examples run two actual services as well as a sample client on one end and a sample destination for requests on the other.
- Proxy service: The proxy service takes the API server requests and forwards them appropriately.
- Agent service: The agent service connects to the proxy and then allows traffic to be forwarded to it.

components are intended to run as standalone binaries and should not be imported as a library. Clients communicating with the network proxy can import the konnectivity-client
module.
