proxy

Installation

curl https://dio.github.io/proxy/install.sh | bash -s -- -b /usr/local/bin

Note: By default the script installs (if executed without -- -b /usr/local/bin) in the current directory: ./bin/proxy.

Running

To generate a proxy config with specified admin and stats ports:

proxy --admin-port 9000 --stats-port 9001 --output a.yaml

Then you can run proxy with that config:

proxy -- -c ./a.yaml

proxy comes with its own xDS server implementation that watches a directory with proxy configs in it. As an example, see: testdata/hello.

proxy --xds-resources testdata/hello --admin-port 9000

This starts proxy with configurations defined in testdata/hello/*.yaml. Note that it watches changes inside that directory. For example, if you change the listener address for listener_0 in testdata/hello/a.yaml, e.g. from 10000 to 10001 it will immediately reflected (this can be checked by visiting the admin interface, in this example: https://localhost:9000)

You can test it out:

curl localhost:10000
curl localhost:10001

If you have a running xDS server already, you can connect to that and set your proxy's Node ID:

# localhost:9901 is the default value for `xds-server-url`.
proxy --node-id my-proxy

proxy --node-id my-proxy --xds-server-url localhost:9902

Note: TLS configuration (and other channel and call credentials) will be added in the next release.

Using Go

proxy is a Go project, hence can be installed using:

go install github.com/dio/proxy@latest

Also, you can go run it directly:

go run github.com/dio/proxy@latest --help

Embedding

See internal/proxy for a sample usage of the public APIs (config, handler, and runner).
