[GitHub] [solr-operator] johgoe opened a new issue #427: Problems with istio and prometheus

[GitBox <gi...@apache.org>]

johgoe opened a new issue #427:
URL: https://github.com/apache/solr-operator/issues/427


   Seems that my cluster runs into https://github.com/prometheus/prometheus/issues/10213
   
   the current port configuration of search-prom-exporter-solr-metrics service looks like
   ```
     ports:
     - name: solr-metrics
       port: 80
       protocol: TCP
       targetPort: 8080
   ```
   
   but istio requires the http protocol to be definied by port name prefix
   
   ```
     ports:
     - name: http-solr-metrics
       port: 80
       protocol: TCP
       targetPort: 8080
   ```
   
   or by appProtocol
   ```
     ports:
     - name: http-solr-metrics
       port: 80
       protocol: TCP
       targetPort: 8080
       appProtocol: http
   ```
   
   I would prefer a solution which is able to add an app protocol
   
   My current SolrPrometheusExporter looks like this
   
   ```
   apiVersion: solr.apache.org/v1beta1
   kind: SolrPrometheusExporter
   metadata:
     name: search-prom-exporter
   spec:
     customKubeOptions:
       podOptions:
         resources:
           requests:
             cpu: 300m
             memory: 900Mi
     solrReference:
       cloud:
         name: "search"
     numThreads: 6
   
   ```
   
   My current serviceMonitor looks like this
   
   ```
   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     labels:
       control-plane: controller-manager
     name: controller-manager-metrics-monitor
   spec:
     selector:
       matchLabels:
         solr-prometheus-exporter: search-prom-exporter
     namespaceSelector:
       matchNames:
         - search
     endpoints:
       - port: solr-metrics
         scheme: https
         tlsConfig:
           caFile: /etc/prometheus/secrets/istio.default/root-cert.pem
           certFile: /etc/prometheus/secrets/istio.default/cert-chain.pem
           insecureSkipVerify: true
           keyFile: /etc/prometheus/secrets/istio.default/key.pem
         interval: 10s
         scrapeTimeout: 10s
   
   ```
