Is there something i am missing out?

@harshalk91 Reference this prior issue: https://github.com/cloudfoundry-incubator/admin-ui/issues/145.

The crash is likely being caused by the admin ui not using the ENV['VCAP_APP_PORT'], but instead trying to listen on your configured port of 8070.

The &. syntax errors are likely due to an older ruby level. The &. construct is a ruby 2.3 addition. Try adding the latest ruby buildpack on your cf push to get the later version of ruby: -b https://github.com/cloudfoundry/ruby-buildpack.git

@rboykin Thank you so much!! I am able to deploy admin-ui as an application. But still confused on which credentials are needed to login on admin-ui

[rboykin]

@harshalk91 You use a UAA managed user to login to the admin ui. The UAA user must be a member of the group designated in your admin ui's default.yml. In your case, you used admin_ui.admin group membership for your admin-enabled group and admin_ui.user group membership for your user-enabled group. As an example, from the https://github.com/cloudfoundry-incubator/admin-ui/blob/master/README.md you can see the following snippet of uaac commands:

Create a new group and add the 'admin' user to it uaac group add admin_ui.admin uaac member add admin_ui.admin admin
