I'm trying to install deploy ceph (pacific 16.2.7) in an air gapped environment. I have a static dump of the basic docker images (saved from an internet facing server) that I import into the air gapped dockerd. I can bootstrap the cluster successfully using
the "--skip-pull" option to "cephadm bootstrap" and the main node seems to come up ok without pulling anything in from outside.
I have read the note here: https://docs.ceph.com/en/pacific/cephadm/install/#deployment-in-an-isolated-environment
but it's a little short on detail...
When adding additional hosts (osds, etc) using "ceph orch host add ...", they always attempt to call out to the external "quay.io" repository. I see how to configure the "global container_image" value to point to a local registry, but that only applies to
the ceph/ceph image. I don't see any way to have the other services pull from a local registry since the image names appear to be hardcoded in /usr/sbin/cephadm (see "DEFAULT_**_IMAGE" global variables in the module).
TL/DR - If I'm running a local registry on the main node, how do I make sure that new hosts pull their images from the local registry instead of failing when attempting to get them externally from quay.io?
thanks,
Wyllys Ingersoll
