Followed the documentation here 

https://docs.onap.org/en/dublin/submodules/policy/apex-pdp.git/docs/APEX-User-Manual.html#running-apex-in-docker

Found couple of issues with the docker run of apex-pdp 

1) The configuration files in /opt/app/policy/apex-pdp/config (for logs etc) are not editable 

2) For rest-editor host is hardcoded as localhost and by default listening on 127.0.0.1 , not able to access from outside docker container through port mapping (-p 18989:18989) . Found the port and host are hardcoded here - https://gerrit.onap.org/r/gitweb?p=policy/apex-pdp.git;a=blob;f=client/client-editor/src/main/java/org/onap/policy/apex/client/editor/rest/ApexEditorParameters.java;hb=c66ebba1fd4fb6365d17e3ed125bfde32913cd00

(Should it be marked as 0.0.0.0 instead of localhost ?) 

3) Build documentation - it is mentioned that 'mvn clean install -DskipTests' is sufficient , but this may not create the tar ball apex-pdp-package-full.tar.gz required for image build. Clarification required on whether -Pdocker profile need to be specified in maven build 

4) In documentation - https://docs.onap.org/en/dublin/submodules/policy/apex-pdp.git/docs/APEX-User-Manual.html#environment-settings-apex-home-and-apex-user,
