Setting Up AWS SSM
Stipulations
To get began with AWS SSM, you’ll want an energetic AWS account and a few EC2 cases. Guarantee that you’ve the required IAM permissions to arrange and use SSM.
Enabling SSM on EC2 Situations
- Open the AWS Administration Console.
- Navigate to the EC2 Dashboard.
- Choose the cases you need to handle with SSM.
- Select “Actions” > “Occasion Settings” > “Connect/Change IAM Position.”
- Choose an current IAM position with SSM permissions or create a brand new position.
- Click on “Apply” to connect the IAM position.
IAM Position and Permissions
It’s essential to configure IAM roles with least privilege rules for enhanced safety. Create a {custom} IAM coverage that features permissions for SSM actions like ssm:SendCommand, ssm:CreateDocument, and others. Connect this coverage to the IAM position you’ve related together with your cases.
Getting Began with SSM
Utilizing the AWS Administration Console
- Navigate to the SSM Dashboard within the AWS Administration Console.
- Discover the assorted functionalities like “Run Command,” “Automation,” “State Supervisor,” and “Patch Supervisor.”
Command Doc and Parameters
SSM operates utilizing paperwork—a JSON or YAML configuration that specifies the actions you need to carry out on cases. Paperwork outline the instructions, parameters, and targets.
SSM Doc Examples
Right here’s a easy SSM doc instance to run a primary shell command:
{
"schemaVersion": "2.2",
"description": "Run a shell command",
"mainSteps": [
{
"action": "aws:runShellScript",
"name": "runShellScript",
"inputs": {
"runCommand": ["echo Hello, SSM!"]
}
}
]
}

Automating Patch Administration
SSM’s Patch Supervisor enables you to automate patching for cases, guaranteeing they’re up-to-date with the newest safety updates.
You should utilize AWS CloudFormation to create a Patch Baseline and affiliate it together with your EC2 cases to automate patch administration.

Run Instructions at Scale
Execute instructions concurrently on a number of cases, streamlining duties like software program installations or log retrieval.
You should utilize the AWS CLI to run instructions on a number of cases utilizing SSM Run Command.
aws ssm create-document --name "MyRunCommandDocument" --document-type "Command" --document-format "JSON" --content '{
"schemaVersion": "2.2",
"description": "Run a {custom} command on cases",
"mainSteps": [
{
"action": "aws:runShellScript",
"name": "runShellScript",
"inputs": {
"runCommand": ["echo Hello from SSM Run Command"]
}
}
]
}'
aws ssm create-association --name "MyAssociation" --targets "Key=InstanceIds,Values=i-1234567890abcdef0,i-abcdef01234567890" --schedule-expression "price(5 minutes)"
Safe File Switch
Switch recordsdata securely between your native machine and cases with out exposing delicate information to safety dangers.
You should utilize AWS SSM Session Supervisor to securely switch recordsdata between your native machine and cases.
aws ssm start-session --target i-1234567890abcdef0
# As soon as contained in the session:
scp /path/to/native/file.txt ec2-user@i-1234567890abcdef0:/dwelling/ec2-user/
Stock and Compliance Administration
Gather complete stock information about your cases and guarantee compliance with organizational insurance policies.
SSM Stock helps you accumulate stock information about your cases.

Hybrid Environments and On-Premises Servers
Lengthen SSM capabilities past AWS to handle on-premises servers in a constant method.
You’ll be able to prolong SSM capabilities to on-premises servers utilizing the SSM Agent.
# Set up SSM Agent on an on-premises server
sudo yum set up -y https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/newest/linux_amd64/amazon-ssm-agent.rpm
# Begin the SSM Agent
sudo systemctl begin amazon-ssm-agent
# Register the on-premises server within the AWS Administration Console
aws ssm create-activation --default-instance-name "MyOnPremServer" --iam-role "arn:aws:iam::123456789012:position/MySSMRole"
Integrating SSM into Your Workflow
Changing SSH and EC2 Key Pairs
By leveraging SSM, you cut back the assault floor and improve safety by minimizing SSH entry.
To switch SSH entry with SSM, you’ll use the AWS Administration Console or AWS CLI to provoke a session to your occasion:
1. Utilizing AWS Administration Console:
- Go to the AWS Programs Supervisor Console.
- Navigate to “Session Supervisor” on the left sidebar.
- Select the occasion you need to entry.
- Click on “Begin session.”
2. Utilizing AWS CLI:
aws ssm start-session --target i-1234567890abcdef0
This command begins an SSM session to the required occasion.
Improved Safety and Auditability
SSM logs and data each motion, offering an audit path for compliance functions.
SSM logs each motion carried out throughout a session, offering an audit path for compliance functions. You’ll be able to entry these logs in Amazon CloudWatch Logs.
1. Viewing SSM Session Logs:
- Open the AWS Administration Console.

- Seek for log teams named
/aws/ssm/SessionManager.
Centralized Administration and Monitoring
Handle all of your cases centrally, simplifying operations and troubleshooting.
You should utilize AWS CloudWatch to create {custom} dashboards for monitoring and centralized administration of your cases.
1. Making a Customized CloudWatch Dashboard:
- Go to the AWS Administration Console.
- Navigate to CloudWatch.
- Within the left sidebar, click on on “Dashboards.”
- Click on “Create dashboard.”
- Add widgets to your dashboard to observe occasion well being, SSM command execution, and different related metrics.
aws cloudwatch put-dashboard --dashboard-name "MyInstanceDashboard" --dashboard-body '{
"widgets": [
{
"type": "metric",
"x": 0,
"y": 0,
"width": 12,
"height": 6,
"properties": {
"view": "timeSeries",
"metrics": [
["AWS/SSM", "CommandsExecuted", "InstanceId", "i-1234567890abcdef0"]
],
"interval": 300,
"stat": "Sum",
"area": "us-east-1"
}
}
]
}'
This code creates a CloudWatch dashboard with a widget displaying the variety of SSM instructions executed on the required occasion.
By integrating SSM into your workflow, you’ll be able to improve safety, enhance auditability, and centralize administration and monitoring, making your infrastructure administration extra environment friendly and strong.
