Unluckily the endpoint does not work. Checking the AJAX call, the response is "Unable to connect to the Activiti server." The ports are open on the firewall ( sudo ufw allow 8082 && sudo ufw allow 8083 )
I'm using Alfresco Process Services v1.9.0 and Docker 18.06.1-ce, build e68fc7a
PS: the documentation and the server log about license is wrong. I tried to put it to $USER_HOME/.activiti/enterprise-license as documented, but it did not work. The log of Spring says the home was `root`, so I created under /root the directories, copied the license file and changed the ownership of the subfolders and the file to my user and the group to "docker". Nothing. I had to upload the license from interface.
