aloosnetmatch opened a new issue, #760:
URL: https://github.com/apache/solr-operator/issues/760
We upgraded out test env from solr-operator 0.8.1 to 0.9.0 and from solr
9.7.0 to 9.8.0.
The prometheus exporter does not seem to work anymore.
The logging tells me this:
`ERROR - 2025-02-26 12:42:40.917;
org.apache.solr.prometheus.exporter.SolrExporter; Must provide either
--base-url or --zk-host
Exception in thread "main" java.lang.NullPointerException: Cannot invoke
"org.apache.solr.prometheus.exporter.SolrScrapeConfiguration.getType()" because
"configuration" is null

I already found this link , which is similar to my issue
https://issues.apache.org/jira/browse/SOLR-17638
In the prometheus-exporter pod, the env variable for "ZK_HOST" seems to have
no value.
>
env:
- name: POD_NAME
valueFrom:
fieldRef:
apiVersion: v1
fieldPath: metadata.name
- name: POD_NAMESPACE
valueFrom:
fieldRef:
apiVersion: v1
fieldPath: metadata.namespace
- name: PORT
value: '8080'
- name: NUM_THREADS
value: '6'
- name: ZK_HOST
- name: CONFIG_FILE
value:
/opt/solr/contrib/prometheus-exporter/conf/solr-exporter-config.xml
resources:
If I set the correct value there for the ZK_HOST in the Deployment , an
additional container starts up which does seem to work.
What can i do to fix this isssue?
