d. Work with the AWS CLI

Your AWS Cloud9 Environment should be ready. Now, you can become familiar with the environment, learn about the AWS CLI, and then create an Amazon S3 bucket with the AWS CLI. This S3 bucket is used in the next module.

AWS Cloud9 IDE Layout

The AWS Cloud9 IDE is similar to a traditional IDE you can find on virtually any system. It comprises the following components:

  • file browser, listing the files located on your instances.
  • opened files in tab format, located at the top
  • terminal tabs, located at the bottom.

AWS Cloud9 also includes the latest version of AWS CLI, but it is always a good practice to verify you are using the latest version. You can verify the AWS CLI version by following the next section.

Cloud9 First Use

Update the AWS CLI

The AWS CLI allows you to manage services using the command line and control services through scripts. Many users choose to conduct some level of automation using the AWS CLI.

Use the copy button in each of the following code samples to quickly copy the command to your clipboard.

Open a Terminal window and paste the following command. The AWS CLI updates the version, if necessary.

pip-3.6 install awscli -U --user

If a warning message appears prompting you to upgrade PIP, ignore it.

Check Existing Amazon EC2 Instances

Use the following commands to display:

  • the general AWS CLI help,
  • the help related to Amazon EC2 commands,
  • the list of your existing instances with their key characteristics and
  • the list of your registered SSH key-pairs.

    aws help
    aws ec2 help
    aws ec2 describe-instances
    aws ec2 describe-key-pairs

Type q to exit the help pages.

Next, you use the AWS CLI to interact with Amazon S3.
