Gaojin,
Some questions and suggestions here:
1) How did you deploy the nginx with new marathon URI? I did not found that
I can configure the new marathon URI with nginx.
2) Can you please send out the curl output for your master node:
a) curl "http://master-ip:5050/master/slaves
<http://9.21.51.123:5050/master/slaves>" 2>/dev/null|python -m json.tool
b) curl "http://master-ip:5050/master/state
<http://9.21.51.123:5050/master/slaves>" 2>/dev/null|python -m json.tool
3) For open source DC/OS issues, it is suggested to post your question to
[email protected] where you can always get instant and professional support.
Thanks,
Guangya
