Answer: AWS Systems Manager (SSM) files are JSON or YAML files that define the parameters and operations required to perform normal operations and manage the management system. The SSM file acts as a guide in the program, allowing you to perform tasks such as configuration, software installation and deployment in various scenarios. This information is for AWS Systems Manager services such as Run Command, State Manager, Automation, and AWS CloudFormation.
2. How are SSM files organized and what are their main features?
Answer: The SSM file has several important properties:
- Schema Version: Indicates the structure of the SSM file used.
- Parameter: Defines an expression that allows customization and flexibility.
- Important steps: There are steps that are ordered to be performed.
- Plugin: Specify the plugin responsible for performing the requested action.
- Output: Provides information or results that can be consumed or used by other AWS services.
These components work together to define the order in which AWS Systems Manager processes an SSM form.
3. How do you create and manage SSM files on AWS?
Answer: You can create and manage SSM files on AWS using the AWS Management Console, AWS CLI, or AWS SDK. The most common steps include:
1. Define the structure and content of the SSM form (including parameters, steps, and plugins).
2. Save the file to an S3 bucket or put it directly in AWS Systems Manager (in the file section).
3. Save the reference file.
4. Optionally grant IAM roles or users the necessary permissions to access and manipulate SSM files.
Once an SSM document is saved, it can be used with various AWS Systems Manager services to perform tasks or tasks.
4.How does the 4th SSM file work with AWS Run Command?
Answer: AWS Run Command allows you to run commands or scripts remotely from one or more EC2 instances or Managed Instances. The SSM file is used to interpret commands or scripts to be executed. You can create an SSM script with required and optional commands and then use the Run Command to execute it on a series of events.
This enables centralized and automatic execution of the command, making it easier to manage and control the state of the instrument.
5. Explain AWS State Manager concepts and their relationship to SSM data.
Answer: AWS State Manager is a feature of AWS Systems Manager that helps you define and control configuration configurations across instances. It leverages SSM data to define and manage desired conditions.
The SSM file contains the instructions and configuration necessary for the state manager to ensure that an instance conforms to a particular policy or configuration. State Manager can help you complete and manage the configuration needed throughout your process by applying changes or fixes based on defined SSM data.
