For the OP - IBM appears to have some relevant info in their CEPH docs: https://www.ibm.com/docs/en/storage-ceph/5?topic=cluster-performing-disconnected-installation Questions: Is it possible to reset “container_image” after the cluster has been deployed? sudo ceph config dump |grep container_image global basic container_image quay.io/ceph/ceph@sha256:aca35483144ab3548a7f670db9b79772e6fc51167246421c66c0bd56a6585468 * And, can it be set using just the repo name (quay.io/ceph/ceph:v18.2.1) or is it going to, under the covers, change it over to the Image ID (quay.io/ceph/ceph@sha256:aca3548 <http://quay.io/ceph/ceph@sha256:aca3548>…) Questionable Use Case — having a cephadmin managed cluster that has more than one architecture — in my case, arm64 and amd64. Maybe not best practice for production, but possibly useful for dev/test and/or migration from one architecture to another. > On Jan 25, 2024, at 1:46 PM, Kai Stian Olstad <ceph+list@xxxxxxxxxx> wrote: > > On 25.01.2024 18:19, Marc wrote: >> More and more I am annoyed with the 'dumb' design decisions of redhat. Just now I have an issue on an 'air gapped' vm that I am unable to start a docker/podman container because it tries to contact the repository to update the image and instead of using the on disk image it just fails.
