# Getting started with AWS Cloud9
Use this tutorial to get started with AWS Cloud9. You can use AWS Cloud9 console or [AWS Command Line Interface (AWS CLI)](https://docs.aws.amazon.com/cli/latest/userguide/) to use the AWS Cloud9 IDE. In this tutorial, you'll learn how to set up an AWS Cloud9 development environment, and then use the AWS Cloud9 IDE to code, run, and debug your first application. For more information about AWS Cloud9, see [What is AWS Cloud9](welcome.md).
To learn more about AWS Cloud9 IDE, see [Tour of the AWS Cloud9 IDE](tour-ide.md).
This tutorial takes approximately one hour to complete.
**Warning**
Completing this tutorial might result in charges to your AWS account. These include possible charges for Amazon EC2. For more information, see [Amazon EC2 Pricing](https://aws.amazon.com/ec2/pricing/).
## Prerequisites
To successfully complete this tutorial, you must first complete the steps in [Setting up AWS Cloud9](setting-up.md).
## Step 1: Create an environment
In this step, you can use the AWS Cloud9 console or the AWS CLI to create an AWS Cloud9 development environment.
**Note**
If you already created the environment that you want to use for this tutorial, open that environment and skip ahead to [Step 2: Basic tour of the IDE](#tutorial-tour-ide).
In AWS Cloud9, a *development environment*, or *environment*, is somewhere where you store your development project's files and run the tools to develop your applications. In this tutorial, you create an *EC2 environment*, and work with the files and tools in that environment.
------
#### [ Create an EC2 Environment with the console ]
1. Sign in to the AWS Cloud9 console:
+ If you're the only one that using your AWS account or you're an IAM user in a single AWS account, go to [https://console.aws.amazon.com/cloud9/](https://console.aws.amazon.com/cloud9/).
+ If your organization uses AWS IAM Identity Center, ask your AWS account administrator for sign-in instructions.
+ If you're a student in a classroom, ask your instructor for sign-in instructions.
1. After you sign in to the AWS Cloud9 console, in the top navigation bar choose an AWS Region to create the environment in. For a list of available AWS Regions, see [AWS Cloud9](https://docs.aws.amazon.com/general/latest/gr/rande.html#cloud9_region) in the *AWS General Reference*.
![\[AWS Region selector in the AWS Cloud9 console\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/consolas_region_new_UX.png)
1. Choose the large **Create environment** button in one of the locations shown.
If you don't already have AWS Cloud9 environments, the button is shown on a welcome page.
![\[Welcome page in the AWS Cloud9 console\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/create_welcome_env_new_UX.png)
If you already have AWS Cloud9 environments, the button is shown as follows.
![\[Create environment button in the AWS Cloud9 console\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/console_create_env_new_UX.png)
1. On the **Create environment** page, for **Name**, enter a name for your environment.
1. For **Description**, enter something about your environment. For this tutorial, use `This environment is for the AWS Cloud9 tutorial.`
1. For **Environment type**, choose **New EC2 instance** to create an Amazon EC2 environment:
+ **New EC2 instance** – Launches a new Amazon EC2 instance that AWS Cloud9 can connect to directly over SSH. You can use the Systems Manager to interact with new Amazon EC2 instances, for more information, see [Accessing no-ingress EC2 instances with AWS Systems Manager](ec2-ssm.md).
+ ** Existing compute ** – Launches an existing Amazon EC2 instance that requires SSH login details for which the Amazon EC2 instance must have an inbound security group rule.
+ If you select the **Existing compute** option, a service role is automatically created. You can view the name of the service role in a note at the bottom of the setup screen.
**Note**
Automatic shutdown will not be available for AWS Cloud9 environments created using an Amazon EC2 instance using existing compute.
**Warning**
Creating an Amazon EC2 instance for your environment might result in possible charges to your AWS account for Amazon EC2. There's no additional cost to use Systems Manager to manage connections to your EC2 instance.
1. On the New EC2 instance panel for **Instance type**, keep the default choice. This option might have less RAM and fewer vCPUs. However, this amount of memory is sufficient for this tutorial.
**Warning**
Choosing instance types with more RAM and vCPUs might result in additional charges to your AWS account for Amazon EC2.
1. For **Platform**, choose the type of Amazon EC2 instance that you want: **Amazon Linux 2023**, **Amazon Linux 2** or **Ubuntu 22.04 LTS**. AWS Cloud9 creates the instance and then connects the environment to it.
**Important**
We recommend that you choose the **Amazon Linux 2023** option for your EC2 environment. In addition to providing a secure, stable, and high-performance runtime environment, Amazon Linux 2023 AMI includes long-term support through 2024.
For more information, see the [AL2023 page](https://aws.amazon.com/linux/amazon-linux-2023/).
1. Choose a time period for **Timeout**. This option determines how long AWS Cloud9 is inactive before auto-hibernating. When all web browser instances that are connected to the IDE for the environment are closed, AWS Cloud9 waits the amount of time specified and then shuts down the Amazon EC2 instance for the environment.
**Warning**
Choosing a longer time period might result in more charges to your AWS account.
1. On the **Network settings** panel, choose how your environment is accessed from the two following options:
+ **AWS System Manager (SSM)** – This method accesses the environment using SSM without opening inbound ports.
+ **Secure Shell (SSH)** – This method accesses the environment using SSH and requires open inbound ports.
1. Choose **VPC Settings** to display the Amazon Virtual Private Cloud and Subnet for your environment. AWS Cloud9 uses Amazon Virtual Private Cloud (Amazon VPC) to communicate with the newly created Amazon EC2 instance. For this tutorial, we recommend that you don't change the preselected default settings. With the default settings, AWS Cloud9 attempts to automatically use the default VPC with its single subnet in the same AWS account and Region as the new environment.
You can find more information about Amazon VPC choices in [Create an EC2 Environment with the Console](create-environment-main.md#create-environment-vpc-step), and in [VPC settings for AWS Cloud9 Development Environments](vpc-settings.md).
1. Add up to 50 tags by supplying a **Key** and **Value** for each tag. Do so by selecting **Add new tag**. The tags are attached to the AWS Cloud9 environment as resource tags, and are propagated to the following underlying resources: the CloudFormation stack, the Amazon EC2 instance, and Amazon EC2 security groups. To learn more about tags, see [Control Access Using AWS Resource Tags](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html) in the *[IAM User Guide](https://docs.aws.amazon.com/IAM/latest/UserGuide/)* and [advanced information](tags.md) in this guide.
**Warning**
If you update these tags after you create them, the changes aren't propagated to the underlying resources. For more information, see [Propagating tag updates to underlying resources](tags.md#tags-propagate) in the advanced information about [tags](tags.md).
1. Choose **Create** to create your environment, and then you're redirected to the home page. If the account is successfully created, a green flash bar appears at the top of the AWS Cloud9 console. You can select the new environment and choose **Open in Cloud9** to launch the IDE.
![\[AWS Cloud9 IDE selector in the AWS Cloud9 console\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/cloud9-ide-open.png)
If the account fails to create, a red flash bar appears at the top of the AWS Cloud9 console. Your account might fail to create because of a problem with your web browser, your AWS access permissions, the instance, or the associated network. You can find information about possible fixes in the [AWS Cloud9 Troubleshooting section.](troubleshooting.md#troubleshooting-env-loading)
**Note**
AWS Cloud9 supports both IMDSv1 and IMDSv2. We recommend adopting IMDSv2 as it provides an enhanced level of security compared to IMDSv1. For more information on the benefits of IMDSv2, see [AWS Security Blog](https://aws.amazon.com/blogs/security/defense-in-depth-open-firewalls-reverse-proxies-ssrf-vulnerabilities-ec2-instance-metadata-service/). For information on how to transition to IMDSv2 from IMDSv1, see [Transition to using Instance Metadata Service Version 2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-metadata-transition-to-version-2.html) in the *Amazon EC2 User Guide for Linux Instances*.
**Note**
If your environment is using a proxy to access the internet, you must provide proxy details to AWS Cloud9 so it can install dependencies. For more information, see [Failed to install dependencies](troubleshooting.md#proxy-failed-dependencies).
------
#### [ Create an EC2 environment with the AWS CLI ]
1. Install and configure the AWS CLI, if you have not done so already. To do this, see the following in the *AWS Command Line Interface User Guide*:
+ [Installing the AWS Command Line Interface](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html)
+ [Quick configuration](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-quick-configuration)
You can configure the AWS CLI using credentials for one of the following:
+ The IAM user you created in [Setting up Team for AWS Cloud9](setup.md).
+ An IAM administrator in your AWS account, if you will be working regularly with AWS Cloud9 resources for multiple users across the account. If you cannot configure the AWS CLI as an IAM administrator, check with your AWS account administrator. For more information, see [Creating your first IAM admin user and group](https://docs.aws.amazon.com/IAM/latest/UserGuide/getting-set-up.html#create-an-admin) in the *IAM User Guide*.
+ An AWS account root user, but only if you will always be the only one using your own AWS account, and you don't need to share your environments with anyone else. We don't recommend this option as it isn't an AWS security best practice. For more information, see [Creating, Disabling, and Deleting Access Keys for Your AWS Account](https://docs.aws.amazon.com/general/latest/gr/managing-aws-access-keys.html#create-aws-access-key) in the *Amazon Web Services General Reference*.
+ For other options, see your AWS account administrator or classroom instructor.
1. In the following AWS Cloud9 command, provide a value for `--region` and `--subnet-id`. Then run the command and make a note of the `"environmentId"` value for later cleanup.
```
aws cloud9 create-environment-ec2 --name my-demo-environment --description "This environment is for the AWS Cloud9 tutorial." --instance-type t2.micro --image-id resolve:ssm:/aws/service/cloud9/amis/amazonlinux-2-x86_64 --region MY-REGION --connection-type CONNECT_SSM --subnet-id subnet-12a3456b
```
In the preceding command:
+ `--name` represents the name of the environment. In this tutorial, we use the name `my-demo-environment`.
+ `--description` represents an optional description for the environment.
+ `--instance-type` represents the type of Amazon EC2 instance AWS Cloud9 will launch and connect to the new environment. This example specifies `t2.micro`, which has relatively low RAM and vCPUs and is sufficient for this tutorial. Specifying instance types with more RAM and vCPUs might result in additional charges to your AWS account for Amazon EC2. For a list of available instance types, see the create environment wizard in the AWS Cloud9 console.
+ `--image-id` specifies the identifier for the Amazon Machine Image (AMI) that's used to create the EC2 instance. To choose an AMI for the instance, you must specify a valid AMI alias or a valid AWS Systems Manager (SSM) path. In the example above, an SSM path for an Amazon Linux 2 AMI is specified.
For more information, see [create-environment-ec2](https://docs.aws.amazon.com/cli/latest/reference/cloud9/create-environment-ec2.html) in the *AWS CLI Command Reference*.
+ `--region` represents the ID of the AWS Region for AWS Cloud9 to create the environment in. For a list of available AWS Regions, see [AWS Cloud9](https://docs.aws.amazon.com/general/latest/gr/rande.html#cloud9_region) in the *Amazon Web Services General Reference*.
+ `--connection-type CONNECT_SSM` specifies that AWS Cloud9 connects to its Amazon EC2 instance through Systems Manager. This option ensures no inbound traffic to the instance is allowed. For more information, see [Accessing no-ingress EC2 instances with AWS Systems Manager](ec2-ssm.md).
**Note**
When using this option, you need to create the `AWSCloud9SSMAccessRole` service role and `AWSCloud9SSMInstanceProfile` if they aren't already created. For more information, see [Managing instance profiles for Systems Manager with the AWS CLI](ec2-ssm.md#aws-cli-instance-profiles).
+ `--subnet-id` represents the subnet you want AWS Cloud9 to use. Replace `subnet-12a3456b` with the ID of the subnet of an Amazon Virtual Private Cloud (VPC), which must be compatible with AWS Cloud9. For more information, see [Create a VPC plus other VPC resources](vpc-settings.md#vpc-settings-create-vpc) in *[VPC settings for AWS Cloud9 Development Environments](vpc-settings.md)*.
+ AWS Cloud9 shuts down the Amazon EC2 instance for the environment after all web browser instances that are connected to the IDE for the environment have been closed. To configure this time period, add `--automatic-stop-time-minutes` and the number of minutes. A shorter time period might result in fewer charges to your AWS account. Likewise, a longer time might result in more charges.
+ By default, the entity that calls this command owns the environment. To change this, add `--owner-id` and the Amazon Resource Name (ARN) of the owning entity.
1. After you successfully run this command, open the AWS Cloud9 IDE for the newly created environment. To do this, see [Opening an environment in AWS Cloud9](open-environment.md). Then return to this topic and continue with [Step 2: Basic tour of the IDE](#tutorial-tour-ide) to learn how to use the AWS Cloud9 IDE to work with your new environment.
If you try to open the environment, but AWS Cloud9 doesn't display the IDE after at least five minutes, there might be a problem with your web browser, your AWS access permissions, the instance, or the associated VPC. For possible fixes, see [Can't open an environment](troubleshooting.md#troubleshooting-env-loading).
------
## Step 2: Basic tour of the IDE
This part of the tutorial introduces some of the ways that you can use the AWS Cloud9 IDE to create and test applications.
+ You can use an **editor** window to create and edit code.
+ You can use a **terminal** window or a **Run Configuration** window to run your code without debugging it.
+ You can use the **Debugger** window to debug your code.
Perform these three tasks using JavaScript and the Node.js engine. For instructions on using other programming languages, see [Tutorials for AWS Cloud9](tutorials.md).
### Get your environment ready
Most of the tools that you need to run and debug JavaScript code are already installed for you. However, you need one additional Node.js package for this tutorial. Install it as follows.
1. On the menu bar at the top of the AWS Cloud9 IDE, choose **Window**, **New Terminal** or use an existing terminal window.
1. In the terminal window, which is one of the tabs in the bottom portion of the IDE, enter the following.
```
npm install readline-sync
```
Verify that the result is similar to the following. If `npm WARN` messages are also displayed, you can ignore them.
```
+ readline-sync@1.4.10
added 1 package from 1 contributor and audited 5 packages in 0.565s
found 0 vulnerabilities
```
### Write code
Begin by writing some code.
1. On the menu bar, choose **File**, **New File**.
1. Add the following JavaScript to the new file.
```
var readline = require('readline-sync');
var i = 10;
var input;
console.log("Hello Cloud9!");
console.log("i is " + i);
do {
input = readline.question("Enter a number (or 'q' to quit): ");
if (input === 'q') {
console.log('OK, exiting.')
}
else{
i += Number(input);
console.log("i is now " + i);
}
} while (input != 'q');
console.log("Goodbye!");
```
1. Choose **File**, **Save**, and then save the file as `hello-cloud9.js`.
### Run your code
Next, you can run your code.
Depending on the programming language that you're using, there might be multiple ways that you can run code. This tutorial uses JavaScript, which you can run using a terminal window or a **Run Configuration** window.
**To run the code using a Run Configuration window**
1. On the menu bar, choose **Run**, **Run Configurations**, **New Run Configuration**.
1. In the new **Run Configuration** window (one of the tabs in the bottom portion of the IDE), enter `hello-cloud9.js` in the **Command** field, and then choose **Run**.
1. Make sure that the **Run Configuration** prompt is active, and then interact with the application by entering a number at the prompt.
1. View the output from your code in the **Run Configuration** window. It is similar to the following.
![\[Run code in a Run Configuration.\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-run-run-config.png)
**To run the code using a terminal window**
1. Go to the terminal window that you used earlier (or open a new one).
1. In the terminal window, enter `ls` at the terminal prompt, and verify that your code file is in the list of files.
1. Enter `node hello-cloud9.js` at the prompt to start the application.
1. Interact with the application by entering a number at the prompt.
1. View the output from your code in the terminal window. It is similar to the following.
![\[Run code in a Run Configuration.\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-run-terminal.png)
### Debug your code
Finally, you can debug your code by using the **Debugger** window.
1. Add a breakpoint to your code at line 10 (`if (input === 'q')`) by choosing the margin next to line 10. A red circle is displayed next to that line number, as follows.
![\[Adding a breakpoint to the code.\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-debug-breakpoint.png)
1. Open the **Debugger** window by choosing the **Debugger** button on the right side of the IDE. Alternatively, choose **Window**, **Debugger** on the menu bar.
Then, put a watch on the `input` variable by choosing **Type an expression here** in the **Watch Expressions** section of the **Debugger** window.
![\[Debugger window, set watch\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-debug-watch.png)
1. Go to the **Run Configuration** window that you used earlier to run the code. Choose **Run**.
Alternately, you can open a new **Run Configuration** window and start running the code. Do so by choosing **Run**, **Run With**, **Node.js** from the menu bar.
1. Enter a number at the **Run Configuration** prompt and see that the code pauses at line 10. The **Debugger** window shows the value that you entered in **Watch Expressions**.
![\[Program stops at breakpoint\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-debug-break.png)
1. In the **Debugger** window, choose **Resume**. This is the blue arrow icon that's highlighted in the previous screenshot.
1. Select **Stop** in the **Run Configuration** window to stop the debugger.
![\[Deleting an environment in the environment details page\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/basic-ide-debug-stop.png)
## Step 3: Clean up
To prevent ongoing charges to your AWS account that are related to this tutorial, delete the environment.
**Warning**
You cannot restore your environment after you delete it.
------
#### [ Delete the Environment by using the AWS Cloud9 console ]
1. To open the dashboard, on the menu bar in the IDE, choose **AWS Cloud9**, **Go To Your Dashboard**.
1. Do one of the following:
+ Choose the title inside of the **my-demo-environment** card, and then choose **Delete**.
![\[Deleting an environment in the environment details page\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/console-delete-env.png)
+ Select the **my-demo-environment** card, and then choose **Delete**.
![\[Deleting an environment in the environments list\]](http://docs.aws.amazon.com/cloud9/latest/user-guide/images/console-delete-env-card.png)
1. In the **Delete** dialog box, enter `Delete`, and then choose **Delete**. The delete operation takes a few minutes.
**Note**
If you followed this tutorial exactly, then the environment was an EC2 environment and AWS Cloud9 also terminates the Amazon EC2 instance that was connected to that environment.
However, if you used an SSH environment instead of following the tutorial, and that environment was connected to an Amazon EC2 instance, AWS Cloud9 doesn't terminate that instance. If you don't terminate that instance later, your AWS account might continue to have ongoing charges for Amazon EC2 that are related to that instance.
------
#### [ Delete the Environment with the AWS CLI ]
1. Run the AWS Cloud9 `delete-environment` command, specifying the ID of the environment to delete.
```
aws cloud9 delete-environment --region MY-REGION --environment-id 12a34567b8cd9012345ef67abcd890e1
```
In the preceding command, replace `MY-REGION` with the AWS Region in which the environment was created and `12a34567b8cd9012345ef67abcd890e1` with the ID of the environment to delete.
If you didn't save the ID when you created the environment, the ID can be found by using the AWS Cloud9 console. Select the name of the environment in the console, then find the last part of the **Environment ARN**.
1. If you created an Amazon VPC for this tutorial and you no longer need it, delete the VPC using the Amazon VPC console at [https://console.aws.amazon.com/vpc](https://console.aws.amazon.com/vpc).
