如何列出fabfile中定义的角色？

Question

I defined several roles in my fabfile env.rolesdef . How can I list the roles with the fab command line tool?

Answer 1

AFAIK it is not possible out of the box, but you can write a simple task:

@task
def show_roles():
    for key, value in sorted(env.roledefs.items()):
        print key, value

Call it like this:

fab show_roles

dev-server ['devel1', 'devel2', ...]
dev-server-root ['root@...', ..]
dev-systems <function get_roledefs_dev at 0x22bc230>
....
