[GitHub] [lucene-solr-operator] khauser opened a new issue #233: Our client needs zookeeper hosts

khauser opened a new issue #233:
URL: https://github.com/apache/lucene-solr-operator/issues/233


   Hi,
   
   in our current software we use the client library "solr-solrj" to connect to our solr/zookeeper installation (on virtual machines).
   
   build.gradle
   ```
   implementation("org.apache.solr:solr-solrj:8.4.1")
   ```
   
   In code we are then able to connect to solr by adding a list of valid zookeeper hosts.
   ```
   import org.apache.solr.client.solrj.impl.CloudSolrClient
   ...
   var zkHosts: List<String> = mutableListOf("localhost:8983")
   var path: Optional<String> = Optional.empty() //Optional.of("/solr")
   
   val client = CloudSolrClient.Builder(zkHosts, path).build()
   ```
   As far as we understood is that a zookeeper instance is called to return a valid solr instance with which our application can work internally.
   
   We now have moved our solr/zookeeper installation into kubernetes using this operator and now fail to connect our software with it from outsite the cluster. We only see that the solr-service is exposable via LB or Ingress but no zookeeper.
   
   What are your recommentations to proceed here? Switch to another client library or change the way we use it? Could the zookeepers be exposed and be configured to return the exposed solr instances?
   
   Thanks for help
   Karsten

   We now added an additional LB in front of the zookeeper instances in Azure with a private IP:
   ```
   apiVersion: v1
   kind: Service
   metadata:
     name: solr-zookeeper-internal-lb
     annotations:
       service.beta.kubernetes.io/azure-load-balancer-internal: "true"
   spec:
     type: LoadBalancer
     ports:
     - port: 2181
     selector:
       app: solr-cloud-solrcloud-zookeeper
   ```
   
   Together with the SolrClound+Ingress definition:
   ```
   apiVersion: solr.bloomberg.com/v1beta1
   kind: SolrCloud
   metadata:
     name: perftest-solr-cloud
   spec:
     replicas: 3
     solrImage:
       tag: 8.7.0
     solrJavaMem: "-Xms300m -Xmx300m"
     solrAddressability:
       external:
         method: Ingress
         useExternalAddress: true
         domainName: "<our_domain>"
   ```
   it seems to work properly.
   
   Thanks for your great work!
