+# onap-java
+
+This project aims to produce a reference ONAP baseline including JAVA 11.
+It is based on the image 11.0.5-jre-slim maintained by the upstream community
+openjdk.
+
+It includes a user and a group onap.
+
+When you create your own docker from this baseline docker (build thanks to the 
+Dockerfile hosted in this repository), you need to copy your jar file under
+/opt/onap/app.jar.
+
+You may specify 2 env variable to customize the way you are starting java:
+
+- ENV JAVA_OPTS: set to -Xms256m -Xmx1g by default
+- ENV JAVA_SEC_OPTS: empty by default
