The currently signed C10 route  (=Phase 1) is a continuous route ending at the south entrance to Greewich DLR station where there is some cycle parking. 

However the future 'through route' (going eastwards towards Greenwich Park and on to Bexleyheath) will instead go north on Norman Rd. This is not yet signed although it is considered 'open' on TfL's cycle map.

The current east end of Phase 1 of the route will eventually just become a short 'C10 link' to the DLR station.
