Changing the cluster logging management state
Changing the Elasticsearch management state

In order to modify certain components managed by the Cluster logging Operator or the Elasticsearch Operator, you must set the operator to the unmanaged state.

In unmanaged state, the operators do not respond to changes in the CRs. The administrator assumes full control of individual component configurations and upgrades when in unmanaged state.

Operators in an unmanaged state are unsupported and the cluster administrator assumes full control of the individual component configurations and upgrades. For more information, see Support policy for unmanaged Operators.

In managed state, the Cluster logging Operator (CLO) responds to changes in the Clusterlogging custom resource (CR) and adjusts the logging deployment accordingly.

The OpenShift Container Platform documentation indicates in a prerequisite step when you must set the OpenShift Container Platform cluster to Unmanaged.

If you set the Elasticsearch Operator (EO) to unmanaged and leave the Cluster logging Operator (CLO) as managed, the CLO will revert changes you make to the EO, as the EO is managed by the CLO.

Changing the cluster logging management state

You must set the operator to the unmanaged state in order to modify the components managed by the Cluster logging Operator:

the Curator CronJob,
the Elasticsearch CR,
the Kibana Deployment,
the log collector DaemonSet.

If you make changes to these components in managed state, the Cluster logging Operator reverts those changes.

An unmanaged cluster logging environment does not receive updates until you return the Cluster logging Operator to Managed state.

Prerequisites

The Cluster logging Operator must be installed.

Procedure

Edit the Clusterlogging custom resource (CR) in the openshift-logging project:

$ oc edit Clusterlogging instance

$ oc edit Clusterlogging instance

apiVersion: "logging.openshift.io/v1"
kind: "Clusterlogging"
metadata:
  name: "instance"

....

spec:
  managementState: "Managed" (1)

1	Specify the management state as `Managed` or `Unmanaged`.

Changing the Elasticsearch management state

You must set the operator to the unmanaged state in order to modify the Elasticsearch deployment files, which are managed by the Elasticsearch Operator.

If you make changes to these components in managed state, the Elasticsearch Operator reverts those changes.

An unmanaged Elasticsearch cluster does not receive updates until you return the Elasticsearch Operator to Managed state.

Prerequisite

The Elasticsearch Operator must be installed.

Have the name of the Elasticsearch CR, in the openshift-logging project:

$ oc get -n openshift-logging Elasticsearch
NAME            AGE
elasticsearch   28h

Procedure

Edit the Elasticsearch(CR) in the openshift-logging project:

$ oc edit Elasticsearch elasticsearch

apiVersion: logging.openshift.io/v1
kind: Elasticsearch
metadata:
  name: elasticsearch


....

spec:
  managementState: "Managed" (1)

1	Specify the management state as `Managed` or `Unmanaged`.

If you set the Elasticsearch Operator (EO) to unmanaged and leave the Cluster logging Operator (CLO) as managed, the CLO will revert changes you make to the EO, as the EO is managed by the CLO.
