Hi All ,

Would need help!

I tried executing the script present in the link
https://github.com/openstack/barbican/blob/master/bin/barbican-api  to
start the barbican instance but  the use cases of barbican are failing.
Please find the details of the investigations :

Usecase for posting and retrieving the secret.

[root at barbican-keystone2 ~]# curl -X POST -H
'content-type:application/json' -H 'X-Project-Id:12345' -d '{"payload":
"my-secret-here", "payload_content_type": "text/plain"}'
http://localhost:9311/v1/secrets
{"code": 406, "description": null, "title": "Not
Acceptable"}[root at barbican-keystone2 ~]#

[root at barbican-keystone2 ~]# curl -H 'Accept: application/json' -H
'X-Project-Id:12345' http://localhost:9311/v1/secrets
{"code": 406, "description": null, "title": "Not
Acceptable"}[root at barbican-keystone2 ~]#
[root at barbican-keystone2 ~]#

[root at barbican-keystone2 ~]#  curl -X POST -H
'content-type:application/json' -H 'X-Project-Id:12345' -d '{"payload":
"my-secret-here", "payload_content_type": "text/plain"}'
http://127.0.0.1:9311/v1/secrets
{"code": 406, "description": null, "title": "Not
Acceptable"}[root at barbican-keystone2 ~]#

The output of the ps command when the barbican instance is stood up using
the python script as pointed in the above link
We do not see the instance of uwsgi in the response:

[root at barbican-keystone2 ~]# ps -ef | grep barbican
avahi     2920     1  0 Apr22 ?        00:00:00 avahi-daemon: running
[barbican-keystone2.local]
root     14743 14554  2 14:54 pts/1    00:00:01 python bin/barbican-api
root     14781 13975  0 14:55 pts/0    00:00:00 grep --color=auto barbican

The output of the ps command when the barbican instance is stood up using
the barbican.sh script
[root at barbican-keystone2 ~]# ps -ef | grep barbican
avahi     2920     1  0 Apr22 ?        00:00:00 avahi-daemon: running

/usr/bin/uwsgi --ini barbican-api.ini*
root     14601 13975  0 14:50 pts/0    00:00:00 grep --color=auto barbican

The barbican instance needs to be started on top of uswgi server instance
since uwsgi is the webserver which serves the request for barbican
services. The script does not start the uwsgi server

Please correct me if I am wrong.
Any help would be highly appreciated.

Thanks and Regards,
Asha Seshagiri
