Default images
~~~~~~~~~~~~~~
*The information in this section was developed by Eugen Block in a thread on
the [ceph-users] mailing list in April of 2024. The thread can be viewed here:
``https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/QGC66QIFBKRTPZAQMQEYFXOGZJ7RLWBN/``.*
``cephadm`` stores a local copy of the ``cephadm`` binary in
``var/lib/ceph/{FSID}/cephadm.{DIGEST}``, where ``{DIGEST}`` is an alphanumeric
string representing the currently-running version of Ceph.
To see the default container images, run a command of the following form:
.. prompt:: bash #
grep -E "DEFAULT*IMAGE" /var/lib/ceph/{FSID}/cephadm.{DIGEST}
::
DEFAULT_PROMETHEUS_IMAGE = 'quay.io/prometheus/prometheus:v2.51.0'
DEFAULT_LOKI_IMAGE = 'docker.io/grafana/loki:2.9.5'
DEFAULT_PROMTAIL_IMAGE = 'docker.io/grafana/promtail:2.9.5'
DEFAULT_NODE_EXPORTER_IMAGE = 'quay.io/prometheus/node-exporter:v1.7.0'
DEFAULT_ALERT_MANAGER_IMAGE = 'quay.io/prometheus/alertmanager:v0.27.0'
DEFAULT_GRAFANA_IMAGE = 'quay.io/ceph/grafana:10.4.0'
Default monitoring images are specified in
``/src/cephadm/cephadmlib/constants.py`` and in
``/src/pybind/mgr/cephadm/module.py``.
