Ceph » Orchestrator

It was difficult to find the way to use alternate images for services.

At first I tried registry-mirrors in /etc/docker/daemon.json but it works only for docker.io, but not quay.io.

Then I finally tried with success the method described in https://tracker.ceph.com/issues/46561

Mirrors are hosted in a Sonatype Nexus OSS in https:

• The docker.io mirror is listening on port 18079.
• The quay.io mirror is listening on port 18080.

During deployment I used:

export CEPHADM_IMAGE='myrepo:18080/ceph/ceph:v16'

cephadm bootstrap \
  --mon-ip 192.168.25.5 \
  --ssh-private-key /home/cephadm/.ssh/id_rsa \
  --ssh-public-key /home/cephadm/.ssh/id_rsa.pub \
  --ssh-user cephadm

ceph config set mgr mgr/cephadm/container_image_prometheus myrepo:18080/prometheus/prometheus:v2.18.1
ceph config set mgr mgr/cephadm/container_image_node_exporter myrepo:18080/node-exporter:v0.18.1
ceph config set mgr mgr/cephadm/container_image_alertmanager myrepo:18080/prometheus/alertmanager:v0.20.0
ceph config set mgr mgr/cephadm/container_image_grafana myrepo:18080/ceph/ceph-grafana:6.7.4
ceph config set mgr mgr/cephadm/container_image_haproxy myrepo:18079/library/haproxy:2.3
ceph config set mgr mgr/cephadm/container_image_keepalived myrepo:18079/arcts/keepalived

It worked for me but is it the correct way to do it ? If so, a reference can be added in documentation.
