The colocation would work, but the problem you're having with router and
apigateway is preventing it from getting that far. In other words,
router and apigateway are still running on the node (they have not been
successfully stopped), so the colocation is still valid.

I suspect that the return codes from your custom resource agents may be
the issue. Make sure that your agents conform to these guidelines:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html-single/Pacemaker_Explained/index.html#ap-ocf

In particular, "start" should not return until a monitor operation would
return success, "stop" should not return until a monitor would return
"not running", and "monitor" should return "not running" if called on a
host where the service hasn't started yet. Be sure you are returning the
proper OCF_* codes according to the table in the link above.

If the documentation is unclear, please ask here about anything you are
unsure of.
