Open Telemetry and Docker

[mdemare]

Docker compose setup in which to run api, worker, redis and prometheus.

After starting the dev docker container:
api produces metrics on http://localhost:9464/metrics
worker produces metrics on http://localhost:9465/metrics
prometheus runs on http://localhost:9090/

See docker-compose.yml for the required env vars to setup the open telemetry agent. OTEL_EXPORTER_PROMETHEUS_ENDPOINT is used to set the host and port of the metrics endpoint.

The existing metrics have been migrated to the worker metrics. They look like this:

# TYPE rio_mapper_active_and_queued_job_count gauge
rio_mapper_active_and_queued_job_count{otel_scope_name="steffan-westcott.clj-otel",otel_scope_version="0.2.7",queue_name="demo04.test.surfeduhub.nl"} 0.0
rio_mapper_active_and_queued_job_count{otel_scope_name="steffan-westcott.clj-otel",otel_scope_version="0.2.7",queue_name="demo06.test.surfeduhub.nl"} 0.0
rio_mapper_active_and_queued_job_count{otel_scope_name="steffan-westcott.clj-otel",otel_scope_version="0.2.7",queue_name="endpoint01.sandbox.jomco.nl"} 1.0
# TYPE rio_mapper_http_requests_total counter
rio_mapper_http_requests_total{institution_name="'t Univeersiteitje",otel_scope_name="steffan-westcott.clj-otel",otel_scope_version="0.2.7",schac_home="endpoint01.sandbox.jomco.nl",status="started"} 1.0

docker-compose up geeft de volgende error bij mij:
