Configuring stats sinks

[ivitjuk]

@seubert in addition to providing the whole bootstrap file by yourself, you can create a file with stats config only, mount it in the Envoy container, and pass environment variable ENVOY_STATS_CONFIG_FILE to the container with the full path to the stats config file as it's value.

Our bootstrap script will then detect ENVOY_STATS_CONFIG_FILE variable and include the referenced file into the generated Envoy bootstrap config.

Your stats config should include stats_sinks and stats_config bootstrap sections.

Given the discussion in #98 I'm assuming we've resolved this particular question, so closing the issue. Please re-open if you have any additional configuration issues.

Hey @seubert,

The envoy.dog_statsd sink is configured within the bootstrap configuration of Envoy (i.e. before it can reach out to our systems for dynamic configuration). Our bootstrap configuration is distributed with the 111345817488.dkr.ecr.us-west-2.amazonaws.com/aws-appmesh-envoy:v1.8.0.2-beta docker image.

It is possible to provide a separate bootstrap config to Envoy that would contain the proper sink settings. We have not yet published the Dockerfiles and build scripts for this image (#59), but I can point you in the right direction if you're interested in pursuing this approach.

Alternatively, we are actively working on making DogStatsD configuration easier (#7), and should have an update in this area in the coming weeks, so please watch that issue as well and provide any feedback or use cases of interest there.

Thanks @bcelenza. More info on how to properly provide a separate bootstrap config would be great. Right now I've just copied the generated config from the running Envoy containers, added my own settings, and mounted it at /tmp/envoy.yaml to "override" the generated one. This works but isn't particularly clean and depends on your Dockerfiles/build scripts not changing config path etc.

Thanks for the links to those other issues, I'll keep an eye on them as well.
