To upload a Solr configuration ("sample_techproducts_configs") to ZooKeeper, execute the command (please note the usage of "chroot" znode "/solr"):
$ ${SOLR_ROOT}/server/scripts/cloud-scripts/zkcli.sh \ -zkhost "localhost:2181/solr" \ -cmd upconfig \ -confname solr_config1 \ -confdir ${SOLR_HOME}/configsets/sample_techproducts_configs/conf
You can verify that the configuration is created in ZooKeeper:
$ ${SOLR_ROOT}/bin/solr zk ls /solr/configs -z localhost:2181 $ _default solr_config1
You can notice the configuration "_default" which is, by default, created/uploaded to ZooKeeper when Solr start the first time ("${SOLR_HOME}/configsets/_default").
