Elastic Beanstalk examples using Amazon CLI - Amazon Command Line Interface
Actions
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Elastic Beanstalk examples using Amazon CLI

The following code examples show you how to perform actions and implement common scenarios by using the Amazon Command Line Interface with Elastic Beanstalk.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.

Actions

The following code example shows how to use abort-environment-update.

Amazon CLI

To abort a deployment

The following command aborts a running application version deployment for an environment named my-env:

aws elasticbeanstalk abort-environment-update --environment-name my-env

The following code example shows how to use check-dns-availability.

Amazon CLI

To check the availability of a CNAME

The following command checks the availability of the subdomain my-cname.elasticbeanstalk.com:

aws elasticbeanstalk check-dns-availability --cname-prefix my-cname

Output:

{
    "Available": true,
    "FullyQualifiedCNAME": "my-cname.elasticbeanstalk.com"
}

The following code example shows how to use create-application-version.

Amazon CLI

To create a new application version

The following command creates a new version, "v1" of an application named "MyApp":

aws elasticbeanstalk create-application-version --application-name MyApp --version-label v1 --description MyAppv1 --source-bundle S3Bucket="my-bucket",S3Key="sample.war" --auto-create-application

The application will be created automatically if it does not already exist, due to the auto-create-application option. The source bundle is a .war file stored in an s3 bucket named "my-bucket" that contains the Apache Tomcat sample application.

Output:

{
  "ApplicationVersion": {
      "ApplicationName": "MyApp",
      "VersionLabel": "v1",
      "Description": "MyAppv1",
      "DateCreated": "2015-02-03T23:01:25.412Z",
      "DateUpdated": "2015-02-03T23:01:25.412Z",
      "SourceBundle": {
          "S3Bucket": "my-bucket",
          "S3Key": "sample.war"
      }
  }
}

The following code example shows how to use create-application.

Amazon CLI

To create a new application

The following command creates a new application named "MyApp":

aws elasticbeanstalk create-application --application-name MyApp --description "my application"

The create-application command only configures the application's name and description. To upload source code for the application, create an initial version of the application using create-application-version. create-application-version also has an auto-create-application option that lets you create the application and the application version in one step.

Output:

{
  "Application": {
      "ApplicationName": "MyApp",
      "ConfigurationTemplates": [],
      "DateUpdated": "2015-02-12T18:32:21.181Z",
      "Description": "my application",
      "DateCreated": "2015-02-12T18:32:21.181Z"
  }
}

The following code example shows how to use create-configuration-template.

Amazon CLI

To create a configuration template

The following command creates a configuration template named my-app-v1 from the settings applied to an environment with the id e-rpqsewtp2j:

aws elasticbeanstalk create-configuration-template --application-name my-app --template-name my-app-v1 --environment-id e-rpqsewtp2j

Output:

{
    "ApplicationName": "my-app",
    "TemplateName": "my-app-v1",
    "DateCreated": "2015-08-12T18:40:39Z",
    "DateUpdated": "2015-08-12T18:40:39Z",
    "SolutionStackName": "64bit Amazon Linux 2015.03 v2.0.0 running Tomcat 8 Java 8"
}

The following code example shows how to use create-environment.

Amazon CLI

To create a new environment for an application

The following command creates a new environment for version "v1" of a java application named "my-app":

aws elasticbeanstalk create-environment --application-name my-app --environment-name my-env --cname-prefix my-app --version-label v1 --solution-stack-name "64bit Amazon Linux 2015.03 v2.0.0 running Tomcat 8 Java 8"

Output:

{
  "ApplicationName": "my-app",
  "EnvironmentName": "my-env",
  "VersionLabel": "v1",
  "Status": "Launching",
  "EnvironmentId": "e-izqpassy4h",
  "SolutionStackName": "64bit Amazon Linux 2015.03 v2.0.0 running Tomcat 8 Java 8",
  "CNAME": "my-app.elasticbeanstalk.com",
  "Health": "Grey",
  "Tier": {
      "Type": "Standard",
      "Name": "WebServer",
      "Version": " "
  },
  "DateUpdated": "2015-02-03T23:04:54.479Z",
  "DateCreated": "2015-02-03T23:04:54.479Z"
}

v1 is the label of an application version previously uploaded with create-application-version.

To specify a JSON file to define environment configuration options

The following create-environment command specifies that a JSON file with the name myoptions.json should be used to override values obtained from the solution stack or the configuration template:

aws elasticbeanstalk create-environment --environment-name sample-env --application-name sampleapp --option-settings file://myoptions.json

myoptions.json is a JSON object defining several settings:

[
  {
    "Namespace": "aws:elb:healthcheck",
    "OptionName": "Interval",
    "Value": "15"
  },
  {
    "Namespace": "aws:elb:healthcheck",
    "OptionName": "Timeout",
    "Value": "8"
  },
  {
    "Namespace": "aws:elb:healthcheck",
    "OptionName": "HealthyThreshold",
    "Value": "2"
  },
  {
    "Namespace": "aws:elb:healthcheck",
    "OptionName": "UnhealthyThreshold",
    "Value": "3"
  }
]

The following code example shows how to use validate-configuration-settings.

Amazon CLI

To validate configuration settings

The following command validates a CloudWatch custom metrics config document:

aws elasticbeanstalk validate-configuration-settings --application-name my-app --environment-name my-env --option-settings file://options.json

options.json is a JSON document that includes one or more configuration settings to validate:

[
    {
        "Namespace": "aws:elasticbeanstalk:healthreporting:system",
        "OptionName": "ConfigDocument",
        "Value": "{\"CloudWatchMetrics\": {\"Environment\": {\"ApplicationLatencyP99.9\": null,\"InstancesSevere\": 60,\"ApplicationLatencyP90\": 60,\"ApplicationLatencyP99\": null,\"ApplicationLatencyP95\": 60,\"InstancesUnknown\": 60,\"ApplicationLatencyP85\": 60,\"InstancesInfo\": null,\"ApplicationRequests2xx\": null,\"InstancesDegraded\": null,\"InstancesWarning\": 60,\"ApplicationLatencyP50\": 60,\"ApplicationRequestsTotal\": null,\"InstancesNoData\": null,\"InstancesPending\": 60,\"ApplicationLatencyP10\": null,\"ApplicationRequests5xx\": null,\"ApplicationLatencyP75\": null,\"InstancesOk\": 60,\"ApplicationRequests3xx\": null,\"ApplicationRequests4xx\": null},\"Instance\": {\"ApplicationLatencyP99.9\": null,\"ApplicationLatencyP90\": 60,\"ApplicationLatencyP99\": null,\"ApplicationLatencyP95\": null,\"ApplicationLatencyP85\": null,\"CPUUser\": 60,\"ApplicationRequests2xx\": null,\"CPUIdle\": null,\"ApplicationLatencyP50\": null,\"ApplicationRequestsTotal\": 60,\"RootFilesystemUtil\": null,\"LoadAverage1min\": null,\"CPUIrq\": null,\"CPUNice\": 60,\"CPUIowait\": 60,\"ApplicationLatencyP10\": null,\"LoadAverage5min\": null,\"ApplicationRequests5xx\": null,\"ApplicationLatencyP75\": 60,\"CPUSystem\": 60,\"ApplicationRequests3xx\": 60,\"ApplicationRequests4xx\": null,\"InstanceHealth\": null,\"CPUSoftirq\": 60}},\"Version\": 1}"
    }
]

If the options that you specify are valid for the specified environment, Elastic Beanstalk returns an empty Messages array:

{
    "Messages": []
}

If validation fails, the response will include information about the error:

{
    "Messages": [
        {
            "OptionName": "ConfigDocumet",
            "Message": "Invalid option specification (Namespace: 'aws:elasticbeanstalk:healthreporting:system', OptionName: 'ConfigDocumet'): Unknown configuration setting.",
            "Namespace": "aws:elasticbeanstalk:healthreporting:system",
            "Severity": "error"
        }
    ]
}
