 3) oom/kubernetes/dmaap/charts/dmaap-bus-controller/resources/config/buscontroller.env contains some environment settings for the container.  These can be modified.  For example, to indicate that AAF integration should be enabled, set USE_AAF=true in this file.
 4) oom/kubernetes/dmaap/charts/dmaap-bus-controller/resources/config/dmaapbc.properties  contains many properties which can be modified.  For example, if a differerent Postgresql instance needed to be used, the value could be specified here.

+Steps for local development and test
+------------------------
+On Intel dev machine, in terminal (> indicates prompt) :
+1) Build buscontroller images
+    > git clone https://gerrit.onap.org/r/dmaap/buscontroller
+        - anonymous http, can't push changes
+    > cd buscontroller
+    > mvn clean install -Pdocker
+        - builds dmaap-bc and dbc-client images
+2) Run tests 
+    > cd dmaap-bc/src/main/resources/
+    > cp docker-databus-controller.conf /var/tmp/
+        - set docker preferences/file sharing to access /var/tmp
+    - edit docker-compose.yml
+        - remove "nexus3.onap.org:10001/" from dmaap-bc:image: and dbc-client:image: to 
+            use local images
+    > docker-compose up -d
+    - create sample.txt file (as above)(content of file not important)
+    > curl http://localhost:30241/webapi/bridge
+
+On Arm:
+1) Build buscontroller images
+    > git clone https://gerrit.onap.org/r/dmaap/buscontroller
+        - anonymous http, can't push changes
+    > cd buscontroller
+    > mvn clean install -Pdocker  -Ddocker.pull.registry=docker.io
+        - ensure we pull Arm version of base image
+2) Run tests 
+    > cd dmaap-bc/src/main/resources/
+    > cp docker-databus-controller.conf /var/tmp/
+        - set docker preferences/file sharing to access /var/tmp
+    - edit docker-compose.yml
+        - remove "nexus3.onap.org:10001/" from dmaap-bc:image: and dbc-client:image: to 
+            use local images
+        - replace 'crunchydata/crunchy-postgres:centos7-10.4-2.0.0' with
+            multi-platform 'postgres:9.6-alpine' normative image
+    > docker-compose up -d
+    - create sample.txt file (as above)(content of file not important)
+    > curl http://localhost:30241/webapi/bridge
