Cloned a service to name "2chord" and it wouldn't start.  Noticed the following error in the Kuberntes logs:

The ReplicationController "sgphws-influx" is invalid:

• spec.template.spec.containers[0].env[10].name: Invalid value: "2CHORDS_PORT_80_TCP_ADDR": must match the regex [A-Za-z_][A-Za-z0-9_]* (e.g. 'my_name' or 'MY_NAME' or 'MyName')
• spec.template.spec.containers[0].env[11].name: Invalid value: "2CHORDS_PORT_80_TCP_PORT": must match the regex [A-Za-z_][A-Za-z0-9_]* (e.g. 'my_name' or 'MY_NAME' or 'MyName')

Apparently we can't have keys starting with anything but  [A-Za-z_]
