# Extends the default docker-compose.yml with Zipkin Server distributed tracing configuration.
# Usage: docker-compose -f ./docker-compose.yml -f ./docker-compose-zipkin.yml up

# NOTE: In Boot 3.0 - 3.3 only global tracing property 'management.tracing.enabled' is available.
# This means in order to disable the other tracer reporters we have to exclude their tracing
# auto-configuration. In Boot 3.4 there is a specific enabled property
# 'management.<product>.tracing.export.enabled' that simplifies this by not requiring the
# auto-configuration exclusion. However, to support all versions of Boot 3.0 - 3.4 we add
# both sets of properties in env vars below.
