in the command line or be started within an IDE.

SpringBoot + Testcontainers (LocalStack + OTEL Collector + Clickhouse)

Checkout branch OTEL, e.g. using

git checkout OTEL

The test only finishes successfully if following ENV variables are set:

JAVA_TOOL_OPTIONS="-javaagent:opentelemetry-javaagent.jar"
OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf;
OTEL_EXPORTER_OTLP_TIMEOUT=60000
OTEL_INSTRUMENTATION_MICROMETER_ENABLED=true;

There is a run.sh script exporting mentioned ENV variables. Following command starts the script:

The test can also be started from an IDE but then the ENV variables have to be configured within the run configuration.
