Run Private registry for Air-Gap cephadm deployment

Run a registry Container and make it to listen port 5000 on all :

podman run --privileged -d --name registry -p 5000:5000 -v /var/lib/registry:/var/lib/registry --restart=always registry:2

Run this Bash script to find proper image needed , chage it of you wnat more component like HAProxy, its for Squid version:

#!/usr/bin/env bash

IMAGES=(

  "quay.io/prometheus/node-exporter"

  "quay.io/prometheus/prometheus"

  "quay.io/ceph/ceph-grafana"

  "quay.io/prometheus/alertmanager"

  "quay.io/ceph/promtail"

  "quay.io/ceph/loki"

)

for image in "${IMAGES[@]}"; do

  echo "Checking latest stable tag for: $image ..."

  # Get tags → remove rc/beta/alpha → sort by version → take last one

  latest_tag=$(skopeo list-tags docker://$image \

    | jq -r '.Tags[]' \

    | grep -Ev 'rc|beta|alpha' \

    | sort -V \

    | tail -n 1)

  if [ -n "$latest_tag" ]; then

    echo "Pulling: $image:$latest_tag"

    podman pull "$image:$latest_tag"

  else

    echo "No stable tag found for $image"

  fi

  echo "------------------------------------"

done

  echo "Pulling Ceph image v19"

  podman pull quay.io/ceph/ceph:v19

  echo "------------------------------"

now we have need to to tags image

podman images  | grep 'quay' | awk '{print $1 " " $3 " " $2}' | cut -d/ -f3- | while read NAME ID TAG ; do podman image tag $ID 172.40.30.21:5000/$NAME:$TAG ; done 

Create directory for insecure registry config, remember to add your IP not mine ! 

mkdir -p  $HOME/.config/containers/

cat << EOF > $HOME/.config/containers/registries.conf

[[registry]]

location = "172.40.30.21:5000"

insecure = true

EOF

Push images to your registry 

for i in $(podman images  | grep '172.40' | awk '{print $1 ":" $2}') ; do podman push $i ; done

Create a initial config to specify image for ceph components 

cat << EOF > $HOME/initial-ceph.conf

[mgr]

mgr/cephadm/container_image_grafana = 172.40.30.21:5000/ceph-grafana:9.4.12-x86_64

mgr/cephadm/container_image_alertmanager = 172.40.30.21:5000/alertmanager:v0.28.1

mgr/cephadm/container_image_loki = 172.40.30.21:5000/loki:3.0.0

mgr/cephadm/container_image_promtail = 172.40.30.21:5000/promtail:3.0.0

mgr/cephadm/container_image_prometheus = 172.40.30.21:5000/prometheus:v3.5.0

mgr/cephadm/container_image_node_exporter = 172.40.30.21:5000/node-exporter:v1.9.1

EOF

Now you can Bootstrap you cluster 

cephadm --image 172.40.30.21:5000/ceph:v19 bootstrap \

--mon-ip *<mon-ip>* \

--cluster-network *<cluster-network-cidr>* \

--config initial-ceph.conf
