Pega Platform 8.3 on Docker

We join two nodes to a single backend database instance, and both nodes show as Normal under

[ Dev Studio ] -> [ Configure ] -> [ Decisioning ] -> [ Infrastructure ] -> [ Services ] -> [ Stream ]  

However in Admin Studio under [ View system & nodes ] only one node shows up in the list.

If we login to the 2nd node pega portal its Admin Studio node list only shows itself. I loosely followed the steps outlined in this article https://community.pega.com/support/support-articles/pega0090-streamserviceexception-cannot-add-new-node

1) Shutdown both pega docker instances

2) Deleted the pega image on disk I did this to ensure the default pega tmp dir is absolutely back to its inital state "/usr/local/tomcat/work/Catalina/localhost/prweb"

3) Use pgadmin and connect to pega db

4) Truncated all the tables pr_sys_statusnodes pr_sys_statusdetails pr_data_stream_nodes pr_data_stream_node_updates pr_data_stream_sessions

5) Change hostname for both nodes in docker-compose.yml

6) Bring up each container watching logs for errors

- Logging into each node only shows itself under the list of nodes in Admin Studio

- Both nodes show up in Stream nodes as Normal


Partial log is attached
