• SpringBoot + Testcontainers (LocalStack + OTEL Collector + Clickhouse)

Checkout tag NO_OTEL, e.g. using

git checkout NO_OTEL

The test can be executed by running command

mvn clean install

in the command line or be started within an IDE.

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.
