Cannot index data using java code when started solr cloud using docker-compose

When hitting the solr-cloud(exposed ports are 8983) from java code using zookeeperURI(exposed port 2181) which are started using docker-compose and error is thrown saying that "org.apache.solr.client.solrj.SolrServerException: No live SolrServers available to handle this request:[http://172.21.0.4:8983/solr/test]".

Is there a way to resolve this?

Using the parameter -u your-hostname when starting Solr finally worked for me. By doing that, I have zookeeper return your-hostname instead of the IP. You can then add:

127.0.0.1 your-hostname

to your /etc/hosts and that should do the magic. As I say, it worked for me.

My docker-compose.xml is as easy as:

version: '2'

services:

  ...

  oesp-zookeeper:
    image: zookeeper:1
    container_name: my-zookeeper
    ports:
      - 2181:2181

  oesp-solr:
    image: solr:1
    container_name: my-solr
    depends_on:
      - my-zookeeper
    ports:
      - 8983:8983

Then I start Solr with:

solr -f -z my-zookeeper:2181 -h solr.docker

The ip address returned to SolrJ (172.21.0.4) is the Ip of the SolrCloud container which is not reachable externally.

To solve to this problem I suggest to specify a hostname for the Solr instance instead of default ip address. Which means that you have to define the SOLR_HOST: solr-cloud environment variable in your docker-compose.yml .

Have a look at this https://github.com/freedev/solrcloud-zookeeper-docker

In particular the file solrcloud/docker-compose.yml is configured as I have described in former lines of my answer.
