Kong open tracing plugin for Elastic APM

[ludovic-pourrat]

This feature is about developing a Kong plugin to instrument Kong to achieve open tracing with the Elastic APM.

The selected integration is agent-less and leveraging the intake API from Elastic.

See https://www.elastic.co/guide/en/apm/server/current/events-api.html

The implementation design is similar to approach taken by https://github.com/Kong/kong-plugin-zipkin

What is the process for me to contribute in this plugin, as I already have a proof-of-concept working ?

See open-tracing in action from the current PoC status.

[ludovic-pourrat]

@zffocussss have you found the information needed in the repo ?

[zffocussss]

@ludovic-pourrat ,yes,I did.

1. use multiple-stages builds,to copy executable to the docker images of kong (/usr/local/bin/elastic-apm)
2. set environment variables to make it work

• KONG_PLUGINSERVER_ELASTIC_APM_QUERY_CMD: /usr/local/bin/elastic-apm -dump
• KONG_PLUGINSERVER_NAMES: elastic-apm
• KONG_PLUGINS: bundled,elastic-apm
