You can also pull from a private 56 registry: 57 58 .. code-block:: console 59 60 $ deisctl config store-daemon set image=registry.mydomain.org:5000/myaccount/myimage:latest 61 62 Be sure that your custom image functions in the same way as the `stock store-daemon image`_ shipped with 63 Deis. Specifically, ensure that it sets and reads appropriate etcd keys. 64 65 .. _`stock store-daemon image`: https://github.com/deis/deis/tree/master/store/daemon
