Question : How to decide which stage is next in spinnaker?
Answer:
"Conditional On Expression" can be used to evaluate each of the possible "next" stages.
A possible scenario is:
Stage A > Execution Options > If stage fails > ignore the failure
Stage B > Execution Options > Conditional on Expression > Add your expression when succesful
Stage C > Execution Options > Conditional on Expression > Add your expression when Stage A fails...
