Part of the script includes using an environment variable. When I run the script myself, everything is fine. But when I run the script with SSM, it can't see the environment variable. This variable needs to be passed to a Python script.
I had originally been trying os. The root user can see it when I run it myself.
Setting up Run Command
It's essential a daemon running on the box that's taking your requests and processing them. It's a very basic product: it doesn't support any of the standard features that come with SSH such as SCP, port forwarding, tunneling, passing of env variables etc.AWS - SSM - Systems Manager (Part 1) - RUN Command DEMO - Execute commands remotely
An alternative way of passing a value you need to a script would be to store it in AWS Systems Manager Parameter Storeand have your script pull the variable from the store. You'll need to update your instance role permissions to have access to ssm:GetParameters for the script web scraping imdb r run to access the value stored.

We're sorry we let you down.
If you've got a moment, please tell us how we can make the documentation better. You can use Run Command from the console to configure instances without having to login to each instance. Before you send a command using Run Command, verify that your instances meet Systems Manager requirements. In the Command document list, choose a Systems Manager document. In the Command parameters section, specify values for required parameters.
In the Targets section, identify the instances on which you want to run this operation by specifying tags, selecting instances manually, or specifying a resource group. If you choose to select instances manually, and an instance you expect to see is not included in the list, see Where are my instances? For Timeout secondsspecify the number of seconds for the system to wait before failing the overall command execution.
For Concurrencyspecify either a number or a percentage of instances on which to run the command at the same time. If you selected targets by specifying tags applied to managed instances or by specifying AWS resource groups, and you are not certain how many instances are targeted, then restrict the number of instances that can run the document at the same time by specifying a percentage.
For Error thresholdspecify when to stop running the command on other instances after it fails on either a number or a percentage of instances.
For example, if you specify three errors, then Systems Manager stops sending the command when the fourth error is received. Instances still processing the command might also send errors. Optional For Output optionsto save the command output to a file, select the Write command output to an Amazon S3 bucket box. Type the bucket and prefix folder names in the boxes. The S3 permissions that grant the ability to write the data to an S3 bucket are those of the instance profile assigned to the instance, not those of the IAM user performing this task.
In the SNS notifications section, if you want notifications sent about the status of the command execution, select the Enable SNS notifications check box. For information about canceling a command, see Canceling a command.
Rerun : This button enables you to run the same command without making changes to it. Copy to new : This button copies the settings of one command to a new command and gives you the option to edit those settings before you run it. Choose a command to rerun. You can rerun a command immediately after executing it from the command details page.
Or, you can choose a command that you previously executed from the Command history tab. Choose either Rerun to run the same command without changes, or choose Copy to new to edit the command settings before you run it. You can update to either the latest version or downgrade to an older version.
When you run the command, the system downloads the version from AWS, installs it, and then uninstalls the version that existed before the command was run. If an error occurs during this process, the system rolls back to the version on the server before the command was run and the command status shows that the command failed.

Thanks for posting this solution. As someone with experience here, would you advocate using paramiko over SSM given its simplicity? The devs in the github issue here: github. I've gotten into cloudformation templates for doing deploys.
It helps to make it clear what you have already deployed in the cf console. Thanks a lot for this. I am going to try Paramiko. Also take a look at the recently-announced EC2 Run Command: aws.You can create logical groups of resources such as applications, different layers of an application stack, or production versus development environments. With Systems Manager, you can select a resource group and view its recent API activity, resource configuration changes, related notifications, operational alerts, software inventory, and patch compliance status.
You can also take action on each resource group depending on your operational needs. Systems Manager provides a central place to view and manage your AWS resources, so you can have complete visibility and control over your operations.
OpsCenter provides a central location where operations engineers and IT professionals can view, investigate, and resolve operational issues related to any AWS resource.
OpsCenter aggregates and standardizes operational issues, referred to as OpsItems, while providing contextually relevant data that helps with diagnosis and remediation. Engineers working on an OpsItem get access to information such as:.
This information helps engineers to investigate and remediate operational issues faster. AWS Systems Manager Explorer is a customizable dashboard, providing key insights and analysis into the operational health and performance of your AWS environment.
Explorer aggregates operational data from across AWS accounts and AWS Regions to help you prioritize and identify where action may be required. Resource groups are a way to create a logical group of resources associated with a particular workload such as different layers of an application stack, or production versus development environments.
For example, you can group different layers of an application, such as the frontend web layer and the backend data layer. Resource groups can be created, updated, or removed programmatically through the API.
Introducing Run Command in EC2
AWS AppConfig helps you deploy application configuration in a managed and a monitored way just like code deployments, but without the need to deploy the code if a configuration value changes. You can deploy your application configurations with similar best practices as code deployments, including staging roll-outs, monitoring alarms, and roll back changes should an error occur. AWS Systems Manager automatically aggregates and displays operational data for each resource group through a dashboard.
Systems Manager eliminates the need for you to navigate across multiple AWS consoles to view your operational data. Systems Manager centralizes all relevant operational data, so you can have a clear view of your infrastructure compliance and performance.
AWS Systems Manager collects information about your instances and the software installed on them, helping you to understand your system configurations and installed applications. You can collect data about applications, files, network configurations, Windows services, registries, server roles, updates, and any other system properties.
The gathered data enables you to manage application assets, track licenses, monitor file integrity, discover applications not installed by a traditional installer, and more.It helps in configuring the services and able to control the multiple services to automate them through scripting.

Sometimes in a huge production environment this tends to be a cumbersome job for managing large fleet of machines. Using this feature we can perform system administrator tasks on Windows based EC2 machines. Currently the following actions are supported in Run Command. Since Run Command runs from the AWS console and no username and password is required to access the instances, questions may arise as to how safe this feature is? Each and every command which is run using Run Command is stored in CloudTrail and also remains in the Console for 30 days.
Run Command shows the output in the console for only characters and the rest of the output is truncated. Refer the Diagram and launch an EC2 instance. Hi Ravi, great post and overview of Run command!

When you add the script to user data, you must enclose it within a special tag. This tag determines whether the commands run in a Command Prompt window or run in Windows PowerShell. To add or change user data, the instance must be in the stopped state.
User data scripts aren't automatically executed when you reboot or start the instance. You can enable user data execution the next time, or every time, that you reboot or start the instance. Connect to your EC2 Windows instance. For Windows Server or lateropen a Windows PowerShell command window and then run the following command:.
From the Amazon EC2 consolestop the instance. Select the instance. Add or update the user data, and then choose Save. Note : To execute user data scripts every time you reboot or restart the instance, add the following:. Start the instance. The user data scripts executes as part of the instance start process. For additional troubleshooting, EC2Launch and EC2Config log files contain the output from the standard output and standard error streams. Log files are located as follows:.
How do I run a command on a new EC2 Windows instance at launch? Last updated: Warning : Before you stop an instance, be aware of the following: If you're not using an Elastic IP Addressthe public IP address is released when you stop the instance.
If this instance has an instance store volumeany data on it is lost when the instance is stopped.
