JBevillC opened a new pull request #3005: Fix optional vnc container
URL: https://github.com/apache/trafficcontrol/pull/3005
 
 
   #### What does this PR do?
   
   This PR fixes a number of problems with the existing vnc `testclient` container:
   
   1) rename the container to `vnc` since that is it's purpose
   2) add `vnc.infra.ciab.test` hostname entry into the static dns server configuration.
   3) move the vnc container under the `optional` containers directory for better organization
   4) updates the shared volume required to get access to shared CA x509 SSL certificate
   5) fixes to allow firefox to start up in a  container without dbus or systemd
   6) default vnc password is now random by default. Override via environment at runtime.
   7) Port changed to 5909 to avoid port collision
   
   New proposed directory structure for optional containers: 
   ```
   cdn-in-a-box/optional
   cdn-in-a-box/optional/docker-compose.$NAME.yml
   cdn-in-a-box/optional/$NAME/
   ```

   #### What is the best way to verify this PR?
   
   1) Add VNC_PASSWD with 6 digit password to variables.env
   2) Start up the CIAB stack using the following alias:
   ```
   alias vdc='docker-compose -f docker-compose.yml -f docker-compose.testclient.yml'
   vdc build 
   vdc kill && vdc rm -f 
   docker volume prune -f
   vdc up
   ```
   3) Connect with vnc client to localhost 5909 with $VNC_PASSWD
   4) firefox should start as soon as the traffic portal is available.
