Managing Elastic Beanstalk Environments with the EB CLI

After installing the EB CLI and configuring your project directory, you are ready to create an Elastic Beanstalk environment using the EB CLI, deploy source and configuration updates, and pull logs and events.


Creating environments with the EB CLI requires a service role. You can create a service role by creating an environment in the Elastic Beanstalk console. If you don't have a service role, the EB CLI attempts to create one when you run eb create.

The following examples use an empty project folder named eb that was initialized with the EB CLI for use with a sample Docker application.

eb create

To create your first environment, run eb create and follow the prompts. If your project directory has source code in it, the EB CLI will bundle it up and deploy it to your environment. Otherwise, a sample application will be used.

~/eb$ eb create
Enter Environment Name
(default is eb-dev): eb-dev
Enter DNS CNAME prefix
(default is eb-dev): eb-dev
WARNING: The current directory does not contain any source code. Elastic Beanstalk is launching the sample application instead.

Your environment can take several minutes to become ready. Press Ctrl-C to return to the command line while the environment is created.

eb status

Run eb status to see the current status of your environment. When the status is ready, the sample application is available at and the environment is ready to be updated.

~/eb$ eb status
Environment details for: elasticBeanstalkExa-env
  Application name: elastic-beanstalk-example

eb health

Use the eb health command to view health information about the instances in your environment and the state of your environment overall. Use the --refresh option to view health in an interactive view that updates every 10 seconds.

eb events

Use eb events to see a list of events output by Elastic Beanstalk.

~/eb$ eb events
2015-06-29 23:21:09    INFO    createEnvironment is starting.
2015-06-29 23:21:10    INFO    Using elasticbeanstalk-us-west-2-EXAMPLE as Amazon S3 storage bucket for environment data.
2015-06-29 23:21:23    INFO    Created load balancer named: awseb-e-g-AWSEBLoa-EXAMPLE
2015-06-29 23:21:42    INFO    Created security group named: awseb-e-gbzqc3jcra-stack-AWSEBSecurityGroup-EXAMPLE
2015-06-29 23:21:45    INFO    Created Auto Scaling launch configuration named: awseb-e-gbzqc3jcra-stack-AWSEBAutoScalingLaunchConfiguration-EXAMPLE

eb logs

Use eb logs to pull logs from an instance in your environment. By default, eb logs pull logs from the first instance launched and displays them in standard output. You can specify an instance ID with the --instance option to get logs from a specific instance.

The --all option pulls logs from all instances and saves them to subdirectories under .elasticbeanstalk/logs.

~/eb$ eb logs --all
Retrieving logs...
Logs were saved to /home/local/ANT/mwunderl/ebcli/environments/test/.elasticbeanstalk/logs/150630_201410
Updated symlink at /home/local/ANT/mwunderl/ebcli/environments/test/.elasticbeanstalk/logs/latest

eb open

To open your environment's website in a browser, use eb open:

~/eb$ eb open

In a windowed environment, your default browser will open in a new window. In a terminal environment, a command line browser (e.g. w3m) will be used if available.

eb deploy

Once the environment is up and ready, you can update it using eb deploy.

This command works better with some source code to bundle up and deploy, so for this example we've created a Dockerfile in the project directory with the following content:


FROM ubuntu:12.04

RUN apt-get update
RUN apt-get install -y nginx zip curl

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
RUN curl -o /usr/share/nginx/www/ -L
RUN cd /usr/share/nginx/www/ && unzip && mv 2048-master/* . && rm -rf 2048-master


CMD ["/usr/sbin/nginx", "-c", "/etc/nginx/nginx.conf"]

This Dockerfile deploys an image of Ubuntu 12.04 and installs the game 2048. Run eb deploy to upload the application to your environment:

~/eb$ eb deploy
Creating application version archive "app-150630_014338".
Uploading elastic-beanstalk-example/ to S3. This may take a while.
Upload Complete.
INFO: Environment update is starting.
 -- Events -- (safe to Ctrl+C) Use "eb abort" to cancel the command.

When you run eb deploy, the EB CLI bundles up the contents of your project directory and deploys it to your environment.


If you have initialized a git repository in your project folder, the EB CLI will always deploy the latest commit, even if you have pending changes. Commit your changes prior to running eb deploy to deploy them to your environment.

eb config

Take a look at the configuration options available for your running environment with the eb config command:

~/eb$ eb config
ApplicationName: elastic-beanstalk-example
DateUpdated: 2015-06-30 02:12:03+00:00
EnvironmentName: elasticBeanstalkExa-env
SolutionStackName: 64bit Amazon Linux 2015.03 v1.4.3 running Docker 1.6.2
    LowerBreachScaleIncrement: '-1'
    UpperBreachScaleIncrement: '1'
    UpperThreshold: '6000000'

This command populates a list of available configuration options in a text editor. Many of the options shown have a null value, these are not set by default but can be modified to update the resources in your environment. See Configuration Options for more information about these options.

eb terminate

If you are done using the environment for now, use eb terminate to terminate it.

~/eb$ eb terminate
The environment "eb-dev" and all associated instances will be terminated.
To confirm, type the environment name: eb-dev
INFO: terminateEnvironment is starting.
