Install a basic cluster
From the CLI
To start a basic test cluster with three master nodes, two data nodes, and one coordinator node, run the following command on the DC/OS CLI.
dcos package install elastic
This command creates a new instance with the default name elastic
. Two instances cannot share the same name, so installing additional instances beyond the default instance requires customizing the name
at install time for each additional instance.
All dcos elastic
CLI commands have a --name
argument allowing you to specify which instance to query. If you do not specify a service name, the CLI assumes a default value matching the package name, elastic
. The default value for --name
can be customized via the DC/OS CLI configuration:
dcos elastic --name=elastic <cmd>
From the web interface
Alternatively, you can install from the DC/OS web interface. If you install Elastic from the DC/OS web interface, the dcos elastic
CLI commands are not automatically installed to your workstation. They may be manually installed using the DC/OS CLI:
dcos package install elastic --cli
After running the package install
command, the service will begin installing.
Enterprise DC/OS installation
Depending on the security mode of the Enterprise DC/OS cluster, Enterprise DC/OS users may need to create a custom .json file and use it to install Elastic.
Create a Configuration File
Create a custom configuration file that will be used to install Elastic, and save it as config.json
. Specify the service account (<service_account_id>
) and a secret path (elastic/<secret-name>
) .
{
"service": {
"service_account": "<service_account_id>",
"service_account_secret": "elastic/<secret-name>"
}
}
Installing with a custom config file
Use the custom configuration file you just created to install Elastic with this command:
dcos package install --options=config.json elastic
Installing with external volumes enabled
Create a custom configuration file that will be used to install Elastic, and save it as config.json
.
{
"service": {
"user": "root"
},
"node": {
"external_volume": {
"enabled": true,
"driver_name": "pxd",
}
}
}
Use the custom configuration file you just created to install Elastic with this command:
dcos package install --options=config.json elastic
Service Deployment
To monitor the deployment of your test instance, install the package cli (see command above) and run the command:
dcos elastic plan status deploy
Once the deploy plan has a status of Complete
, the service is fully deployed.
Service Discovery
To connect a client, query the service for its endpoints.
dcos elastic endpoints
Select an endpoint from the list to see the available connections.
dcos elastic endpoints <endpoint>
Working with the Service
Using the endpoint information, you can connect a client to the service from within the DC/OS cluster (for example, a Marathon app running a client application). See the other sections of the documentation for more details on configuration, operation, and service capabilities.
