Does pravega container works for controller's REST API?

Problem description I started a pravega container as standalone mode and try send REST API to it, but failed.

Problem location I started pravega container with this command docker run -it -e HOST_IP=10.62.130.162 -p 9090:9090 -p 12345:12345 -p 9091:9091 -p 10000:10000 pravega/pravega:latest standalone

Then I send a REST for test but failed.

[root@TestMachine ~]# curl http://10.62.130.162:9090/scops

there is also same error printed in container log

I am not sure this is a bug for pravega container or my command syntax is incorrect?

Suggestions for an improvement

sorry for late response, @shrids your branch works fine! [root@TestMachine ~]# curl http://10.62.130.162:9091/v1/scopes {“scopes”:[{“scopeName”:“_system”}]}

Could you retry with the following steps once you are inside Pravega directory? This would ensure you are using the changes done in the pull request.

2a. git checkout -b shrids-issue-2178-standaloneREST master
2b. git pull https://github.com/shrids/pravega.git issue-2178-standaloneREST
3, ./gradlew clean buildPravegaImage
4, docker run --rm -it -e HOST_IP=10.62.130.162 -p 9090:9090 -p 12345:12345 -p 9091:9091 -p 10000:10000 pravega/pravega:latest standalone
