juju deploy with a series

[Daniel Bidwell]

I am trying to deploy a charm that I am writing for both ubuntu and
centos.  "lxc image alias list" produces:

lxc image alias list
+-------------------+--------------+-------------------+
|       ALIAS       | FINGERPRINT  |    DESCRIPTION    |
+-------------------+--------------+-------------------+
| centos7           | 41c7bb494bbd | centos7           |
+-------------------+--------------+-------------------+
| juju/xenial/amd64 | 1e59027d1d58 | juju/xenial/amd64 |
+-------------------+--------------+-------------------+
| ubuntu-xenial     | 1e59027d1d58 | ubuntu-xenial     |
+-------------------+--------------+-------------------+

"juju deploy ~/charms/xenial/aubase1 --series centos7 aubasecentos"
looks like it is starting, but a "juju status" produces:

juju status

10       down                    pending        centos7

What do I need to do to deploy a centos lxd container with my charm?
