Hello, We are facing an issue with node-exporter entering an error state while upgrading our cluster in an air-gapped environment. Specifically, we are upgrading from quincyv17.2.0 to reefv18.2.2. To facilitate this upgrade, we have set up a custom repository on a separate machine within the same network and pushed required images to this private repository. Here are the images that we have pushed: root@custom-registry:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE 192.168.1.10:5000/ceph/ceph v18.2.2 3c937764e6f5 7 weeks ago 1.25GB 192.168.1.10:5000/ceph/ceph-grafana 9.4.7 954c08fa6188 7 months ago 633MB 192.168.1.10:5000/prometheus/prometheus v2.43.0 a07b618ecd1d 16 months ago 234MB 192.168.1.10:5000/prometheus/alertmanager v0.25.0 c8568f914cd2 19 months ago 65.1MB 192.168.1.10:5000/prometheus/node-exporter v1.5.0 0da6a335fe13 19 months ago 22.5MB Since we have configured insecure private registry, we added following lines in "/etc/containers/registries.conf" file on each node of the cluster. [[registry]] location = "192.168.1.10:5000" insecure = true Ceph image upgradation done by the command (ceph orch upgrade start --image 192.168.1.10:5000/ceph/ceph:v18.2.2) but we encountered issues from the node-exporter image, which fails to start and remains in an error state. For the remaining images ( except ceph ) we used "ceph-config" command. We are here now getting the new images values by executing the following command that seems to be default ones. root@node-01:~# ceph config get mgr mgr/cephadm/container_image_node_exporter quay.io/prometheus/node-exporter:v1.5.0 Does an internet connection is required to pull these images (Monitoring stack components images)? I am unsure because whenever we attempt to run the following command, node-exporter enters an error state and not coming into the running state even after redeploy. root@node-01:~# ceph config set mgr mgr/cephadm/container_image_node_exporter quay.io/prometheus/node-exporter:v1.5.0 Please advise the best approach to upgrade the cluster including all images in Air-gapped environment? Any guidance on resolving this issue would be appreciated. Regards, Mohammad Saif
