Option Settings

You can use the option_settings key to modify the Elastic Beanstalk configuration and define variables that can be retrieved from your application using environment variables. Some namespaces allow you to extend the number of parameters, and specify the parameter names. For a list of namespaces and configuration options, see Configuration Options.

Option settings can also be applied directly to an environment during environment creation or an environment update. Settings applied directly to the environment override the settings for the same options in configuration files. If you remove settings from an environment's configuration, settings in configuration files will take effect. See Precedence for details.

Syntax

The standard syntax for option settings is an array of objects, each having a namespace, option_name and value key.

option_settings: - namespace: namespace option_name: option name value: option value - namespace: namespace option_name: option name value: option value

The namespace key is optional. If you do not specify a namespace, the default used is aws:elasticbeanstalk:application:environment:

option_settings: - option_name: option name value: option value - option_name: option name value: option value

Elastic Beanstalk also supports a shorthand syntax for option settings that lets you specify options as key-value pairs underneath the namespace:

option_settings: namespace: option name: option value

Examples

The following examples set a Tomcat platform-specific option in the aws:elasticbeanstalk:container:tomcat:jvmoptions namespace and an environment property named MYPARAMETER. In standard YAML format:

Example .ebextensions/options.config

option_settings: - namespace: aws:elasticbeanstalk:container:tomcat:jvmoptions option_name: Xmx value: 256m - option_name: MYPARAMETER value: parametervalue

In shorthand format:

Example .ebextensions/options.config

option_settings: aws:elasticbeanstalk:container:tomcat:jvmoptions: Xmx: 256m aws:elasticbeanstalk:application:environment: MYPARAMETER: parametervalue

In JSON:

Example .ebextensions/options.config

{ "option_settings": [ { "namespace": "aws:elasticbeanstalk:container:tomcat:jvmoptions", "option_name": "Xmx", "value": "256m" }, { "option_name": "MYPARAMETER", "value": "parametervalue" } ] }
