# To build an auto-instrumentation image for Java, please:
#  - Grant the necessary access to the jar. `chmod 644  /splunk-otel-javaagent.jar`
#  - Symlink '/splunk-otel-javaagent.jar' to `/javaagent.jar` to support compatability with the
#    https://github.com/open-telemetry/opentelemetry-operator project.
#  - For this docker image to be used for auto-instrumentation by container injection, we use the
#    busybox image because it contains the Linux command cp which must be available.
