The following guide outlines the steps required to manage and solve issues in the UnifiedPush Server which is managed, installed and configured via the UnifiedPush Operator.
|
❗
|
Before checking any of following steps see if the operator pod is running successfully. More info: UnifiedPushOperatorDown |
|
💡
|
Logs can be saved by running oc logs <podname> > <filename>.log. The logs can provide useful information in order to identify the root cause of the issue. They may also contain useful information which should be included when creating any issues against the project for maintainers to check.
|
The pod which runs the UnifiedPush Server is down or is not present in the same namespace of the operator.
-
Check that the UnifiedPushServer CR or UnifiedPushServerWithBackup CR is deployed in the same namespace as the operator by running
oc get UnifiedPushServer. Following the expected result.
$ oc get UnifiedPushServer
NAME AGE
example-unifiedpushserver 9d|
ℹ️
|
The UnifiedPushServer should be applied in the same namespace as the operator. The operator will not be able to manage it in another namespace. |
-
Check the environment variables of the Server
-
Run
oc describe pods -l service=upsℹ️For further information see https://github.com/aerogear/aerogear-unifiedpush-server#container-configuration. ⚠️ It will use the values mapped in the Secret created by the operator with the database pod name.

❗This CR instructs the operator to install and configure the Database and the Service pods. If there is any issues with the creation of any of the following resources the logs of the operator should be checked for relevant errors. 💡Logs can be saved by running oc logs <podname> > <filename>.log. The logs can provide useful information in order to identify the root cause of the issue. They may also contain useful information which should be included when creating any issues against the project for maintainers to check. -

If the Monitoring Service (Metrics) is enabled for the installation, a Grafana Dashboard titled UnifiedPush Operator, and the Prometheus Monitoring instance are created.

Switch to the UPS namespace by running
oc project <namespace>. E.goc project unifiedpush -
Check that UnifiedPushServerWithBackup CR is deployed in the same namespace as the operator by running
oc get UnifiedPushServer. Following the expected result.$ oc get UnifiedPushServer NAME AGE example-unifiedpushserver 9d
ℹ️Just one kind of UnifiedPushServer CR can be applied, however, if the backup service is enable for your installation then it means that it is using the UnifiedPushServerWithBackup CR. -
To ensure that it is the UnifiedPushServer with the Backup see its specs by running
oc describe UnifiedPushServer.-
