Fixed In Version: Doc Type: Known Issue
Doc Text:
.Promtail image remains visible after migration to Alloy During the transition from Promtail to Alloy, cephadm continues to register the Promtail container image to maintain backward compatibility and ensure a smooth migration path. As a result, Promtail still appears in the cephadm `list-images` output after upgrading, even though Alloy is the new default. The behavior is intentional to prevent breaking log collection on clusters that have not fully migrated. No workaround is required. Ignore the Promtail image entry during the supported transition phase. If log collection has fully migrated to Alloy and is verified, you can optionally remove legacy Promtail daemons and images manually. This cleanup is not required for cluster operation.

[root@ceph-vpap-i90r9-4i5plh-node1-installer ~]# cephadm list-images
[mgr]
mgr/cephadm/container_image_prometheus = cp.icr.io/cp/ibm-ceph/prometheus:v4.15
mgr/cephadm/container_image_loki = cp.icr.io/cp/ibm-ceph/logging-loki-rhel8:v3.1.0
mgr/cephadm/container_image_promtail = cp.icr.io/cp/ibm-ceph/promtail-rhel9:v3.0.0
mgr/cephadm/container_image_alloy = registry.redhat.io/rhceph/alloy-rhel10:latest
mgr/cephadm/container_image_node_exporter = cp.icr.io/cp/ibm-ceph/prometheus-node-exporter:v4.15

[ceph: root@ceph-vpap-i90r9-4i5plh-node1-installer /]# ceph config get mgr mgr/cephadm/container_image_promtail
cp.icr.io/cp/ibm-ceph/promtail-rhel9:v3.0.0
