How Do I Connect In-house Developed OpenSearch Dashboards to an OpenSearch Cluster in CSS?

Constraints

Only OpenSearch Dashboards images of the OSS version can be connected to OpenSearch clusters in CSS.

Procedure

1. Create an ECS.
   • The ECS must be within the same VPC as the CSS cluster.
   • Port 5601 must be allowed by the security group associated with the ECS.
   • An EIP must be allocated to the ECS.

   For details, see Elastic Cloud Server (ECS) User Guide.

2. Obtain the address for accessing the OpenSearch cluster of CSS.
   1. In the navigation pane on the left, choose Clusters.
   2. In the cluster list, obtain the IP address of the cluster you want to access from the Private Network Address column. Generally, the IP address format is <host>:<port> or <host>:<port>,<host>:<port>.

      If the cluster has only one node, the IP address and port number of this one node are displayed, for example, 10.62.179.32:9200. If the cluster has multiple nodes, the IP addresses and port numbers of all nodes are displayed, for example, 10.62.179.32:9200,10.62.179.33:9200.

3. Install OpenSearch Dashboards on the ECS and modify the configuration file.
   • The following is an example of the configuration file for a security-mode cluster:

     opensearch.username: "***" //Username of the security cluster
     opensearch.password: "***" //Password of the security cluster
     opensearch.ssl.verificationMode: none
     server.ssl.enabled: false
     server.rewriteBasePath: false
     server.port: 5601
     logging.dest: /home/Ruby/log/kibana.log
     pid.file: /home/Ruby/run/kibana.pid
     server.host: 192.168.xxx.xxx  //IP address or DNS name of the OpenSearch Dashboards server. localhost is recommended.
     opensearch.hosts: http://10.0.0.xxx:9200   //Address for accessing the OpenSearch cluster
     opensearch.requestHeadersWhitelist: ["securitytenant","Authorization"]
     opensearch_security.multitenancy.enabled: true
     opensearch_security.multitenancy.tenants.enable_global: true
     opensearch_security.multitenancy.tenants.enable_private: true
     opensearch_security.multitenancy.tenants.preferred: ["Private", "Global"]
     opensearch_security.multitenancy.enable_filter: false

     

     • In security mode, the opensearch_security_dashboards plug-in must be installed. For details, see security-dashboards-plugin.
     • The version of the installed plug-in must be the same as that of the cluster. To check the plug-in version, run the GET _cat/plugins command.
   • The following is an example of the configuration file for a non-security mode cluster:

     server.port: 5601
     logging.dest: /home/Ruby/log/opensearch-dashboards.log
     pid.file: /home/Ruby/run/opensearch-dashboards.pid
     server.host: 192.168.xxx.xxx  //IP address or DNS name of the OpenSearch Dashboards server. localhost is recommended.
     opensearch.hosts: http://10.0.0.xxx:9200   //Address for accessing the OpenSearch cluster

4. Use a browser on your local PC to access the EIP bound to the ECS. The URL is http://EIP:5601. Log in to OpenSearch Dashboards to access the OpenSearch cluster.
