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``
