How to permit specific group permissions to project in JIRA

I am new to JIRA. I have multiple customers, which I want to have READ only access to their own certain projects. (for instance customer X can access project Y only) The rest, I dont want them to see. In addition, I have developers that I want them to have READ/WRITE permissions.

I didn't quite understand the Permissions Schemes and the Roles and the Project setup to create such scenario.开发者_运维问答

(READ, WRITE permissions I mean for VIEW only and CREATE TICKETS etc...)

Thanks!

Provide them only browse permission, but nothing else. Best is to use project roles to do so, such that you don't need a specific permission scheme per project.

- Create a role 'Customer'
- Create a permission scheme 'Customer Project Permission scheme'
- Configure the permission scheme such that
    - The customer role has browse permissions
    - The developer role has all other (applicable) permissions 
        such as edit, move ...
- Link the permission scheme to a project
- Configure the project such that 
    - the userid(s) of your customer(s) appear as a member 
         of the project role 'customer'.
    - the userid(s) of your developer(s) appear as a member 
         of the project role 'developers'

Check http://confluence.atlassian.com/display/JIRA/Managing+Project+Roles The Atlassian guys are way better than me to explain this stuff.

Hope this helps,
