Hello, i am trying to connect xwiki to remote solr on the same machine using containers. I have realized that containers are aware of each other in the docker network however they are unable to connect with java to create Xwiki’s cores i suppose. On the other hand i can log into these ports (80 and 8983) through the telnet. I have been searching on google, xwiki docs and xwiki forum however nobody met similar problem. I work with the latest version of Solr and Xwiki. Here are some logs:
sudo docker run --name solr -p 8983:8983 -v /home/centos/predefined_essentials_solr:/docker-entrypoint-initdb.d -v /home/centos/solrdata:/opt/solr/server/solr/xwiki solr
In predefined_essentials_solr i have got solr.init.sh and xwiki-platform-search-solr-server-data-12.2.jar
sudo docker run --name xwiki -p 80:8080 -v /home/centos/xwiki:/usr/local/xwiki -e DB_USER=xwiki -e DB_PASSWORD=xwiki -e DB_DATABASE=xwiki -e DB_HOST=<IP_1> -e INDEX_HOST=solr -e INDEX_PORT=8983 -e JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=<IP_2> -Dhttp.proxyPort= -Dhttps.proxyHost=<IP_2> -Dhttps.proxyPort= -Dhttp.nonProxyHosts="<IP_1>|localhost|127.0.0.1" -Xmx512m -XX:MaxPermSize=196m $XWIKI_OPTS" xwiki:lts-postgres-tomcat

I would be glad if somebody could point me out what is more going on here.
Many thanks in advance.
