Ceph Container Images
=====================
.. important::
Using the ``:latest`` tag is discouraged. If you use the ``:latest``
tag, there is no guarantee that the same image will be on each of
your hosts. Under these conditions, upgrades might not work
properly. Remember that ``:latest`` is a relative tag, and a moving
target.
Instead of the ``:latest`` tag, use explicit tags or image IDs. For
example:
``podman pull ceph/ceph:v15.2.0``

Development builds
------------------
We automatically build container images for development ``wip-*``
branches in the ceph-ci.git repositories and push them to Quay at::
https://quay.io/organization/ceph-ci
ceph-ci/ceph
^^^^^^^^^^^^
- This is analogous to the ceph/ceph image above
- TODO: remove the ``wip-*`` limitation and also build ceph.git branches.
