I am using elasticsearch using docker-compose. This is how my docker-compose looks like: elasticsearch: image: elasticsearch:2.4 command: elasticsearch -Des.network.host=0.0.0.0 environment: - cluster.name=docker-cluster - bootstrap.memory\_lock=true - "ES\_JAVA\_OPTS=-Xms512m -Xmx512m" ulimits: memlock: soft: -1 hard: -1 volumes: - /data/elasticsearch:/usr/share/elasticsearch/data I create an index "my\_index" using the above and add in my data. Now in /data/elasticsearch/nodes/ there are multiple nodes from 0/, 1/, 2/. Now, if I create another instance of the elasticsearch container, it is not able to find "my\_index" Why so? ---

Are you creating another instance while the first one is running? ---

Yes. But the path for both the instance is same. `/data/elasticsearch:/usr/share/elasticsearch/data` ---

Each node is a separated instance and has its own data dir. If you want to form a cluster, then change the configuration accordingly. Elasticsearch will then duplicate the data for you wherever data dir is. ---

Can you point me to the relevant link for setting this up correctly? Also, is it possible to have just one node? ---

This and the other related sections [https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html) One node only? Yes. This is what you did yet, no? ---

I don't explicitly set anything. However under nodes, there are multiple directories with id 0,1,2,3,..,12. Each containing a subdirectory called index with a particular index. Now, when I start an instance of the container, I think it loads only one of these directories under nodes. I want each instance to have access to all the indices. How can I achieve it? ---

Your instances need to form a cluster — you can check that with `curl :/_cat/nodes` and the IP and port of an Elasticsearch instance. You will need to configure `discovery.zen.ping.unicast` as [described in the relevant docs](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/modules-discovery-zen.html). PS: We don't support Elasticsearch 2.4 any more, so you should definitely upgrade. Also the Docker image you are using is not from us, but from Docker. You can get our images from [https://www.docker.elastic.co](https://www.docker.elastic.co). ---
