Capybara

A reverse proxy in Rust, which is inspired from Nginx/OpenResty/Envoy.

WARNING: still in an active development!!!

Quick Start

• Prepare Bootstrap YAML

loggers:
  main:
    path: ~/capybara/logs/main.log

providers:
  - kind: static_file
    props:
      path: /your/path/config.yaml

• Prepare config YAML

listeners:
  httpbin:
    listen: 0.0.0.0:80
    protocol:
      name: http
      props:
        client_header_timeout: 30s
    pipelines:
      - name: capybara.pipelines.http.lua
        props:
          # write lua script
          content: |
            local cnts = 0

            function handle_request_line(ctx,request_line)
              -- set the upstream here, which links to 'upstreams.httpbin':
              ctx:set_upstream('upstream://httpbin')
            end

            function handle_status_line(ctx,status_line)
              ctx:replace_header('X-Powered-By','capybara')

              -- set a custom response header which counts the requests:
              cnts = cnts + 1
              ctx:replace_header('X-Capybara-Requests', tostring(cnts))
            end

upstreams:
  httpbin:
    transport: tcp
    resolver: default
    balancer: weighted
    endpoints:
      - addr: httpbin.org:443
        weight: 70
      - addr: postman-echo.com:443
        weight: 30
