Solr container doesn't work with cloud (cluster) Solr client

It is not possible to use the Solr container with the cloud Solr client (CloudSolrClient, this client can be used for accessing Solr clusters), because the following exception is thrown when trying to send any request:

Tried fetching cluster state using the node names we knew of, i.e. [localhost:8983_solr]. However, succeeded in obtaining the cluster state from none of them.If you think your Solr cluster is up and is accessible, you could try re-creating a new CloudSolrClient using working solrUrl(s) or zkHost(s).

You can see this exception after changing this line to
solrClient = new CloudSolrClient.Builder(Collections.singletonList("http://" + solrContainer.getContainerIpAddress() + ":" + solrContainer.getSolrPort() + "/solr")).build(); and running any test in SolrQueryTest.java.

The underlying issue is that the cluster will report 8983 as the port used by Solr, but the container uses a different host port, so localhost:8983 will not be available to the client.

Beginne mit examples/solr-container/src/test/java/com/example/SolrQueryTest.java, insbesondere mit dem unter Zeile 33 beschriebenen CloudSolrClient-Setup. Verfolge, wie der Solr-Container seinen Cluster-Port im Vergleich zum zugeordneten Host-Port meldet. Erledigt ist die Aufgabe, wenn CloudSolrClient-Anfragen über den Container funktionieren und die SolrQueryTest-Tests bestehen.
