@Michael_Coburn the proxy server config in Apache is fairly trivial:
ProxyRequests On
ProxyPreserveHost On
ProxyPass / <a href="http://localhost:10080/">http://localhost:10080/</a>
ProxyPassReverse / <a href="http://localhost:10080/">http://localhost:10080/</a>
The docker container is started using
docker run -d \
-p 127.0.0.1:10080:80 \
–volumes-from pmm-data \
–name pmm \
–restart always \
percona/pmm-server:1
hence why the proxy directs traffic to localhost:10080.
