Hi,

I recommend to create your own (local) container registry to have full control over the images. I also don't use the latest tag but always a specific version tag, that's also what the docs suggest [1]. The docs for an isolated environment [2] briefly describe how to set up your local registry, and in [1] you can also find some information about container images, for example how to set the global ceph image (just an example):
ceph config set global container_image myregistry.domain:/ceph/ceph:v17.2.6

The monitoring images can be set with these config options:

container_image_prometheus
container_image_grafana
container_image_alertmanager
container_image_node_exporter

Regards,
Eugen

Zitat von Satish Patel <satish....@gmail.com>:

Folks,

I am trying to install ceph on 10 node clusters and planning to use
cephadm. My question is if next year i will add new nodes to this cluster
then what docker image version cephadm will use to add new nodes?

Are there any local registry can i create one to copy images locally? How
does cephadm control images?
