The container configuration is located into the file {{server.properties}} and expressed as property (key/value).
A property value can be set using the value of another property as a variable using a placeholder mechanism, and you can add your own properties:
{code}
myserver.host=localhost
petals.topology.url=http://${myserver.host}/petals/${petals.container.name}/topology.xml
