AWS CloudFormation, Template Resource Attributes - Coggle Diagram

- - - - (during stack creation or update)
    - - the Resources
      - Outputs sections
      - using
        
        Fn::Ref
        
        Ref
  - - - Fn::FindInMap
      - !FindInMap
- - - - build complex sets of resources and reuse those templates in multiple contexts
    - - describes all the AWS resources
    - - generation of resources
        
        physical name =
        
        logical name
        
        stack name
        
        unique ID
  - - - stacks created as part of other stacks.
        
        AWS::CloudFormation::Stack resource
      - used to define common, repeated patterns and components
      - hierarchy of stacks
        
        root stack is the top-level stack
        
        each nested stack has an immediate parent stack
    - - created and managed as a single unit
        
        when CF instantiates a template
        
        only actions that the users have permission to do.
      - created, updated, and deleted by creating, updating, and deleting stacks.
      - defined by template
    - - extends functionality of stacks
        
        enable to create,update or delete stacks
        
        with a single operation
        
        across multiple accounts and Regions
    - - applies only during stack updates
        
        prevent stack resources from being unintentionally
        
        updated
        
        some resources might require an interruption or be completely replaced,
        
        resulting in new physical IDs
        
        deleted
      - is a JSON document
        
        defines the update actions
        
        on designeted resources
        
        Only one stack policy per stack
        
        multiple resources can be protected within a single policy
  - - - an entire stack
        
        with status
        
        CREATE_COMPLETE
        
        UPDATE_COMPLETE
        
        UPDATE_ROLLBACK_COMPLETE
        
        UPDATE_ROLLBACK_FAILED
      - individual resources
        
        if don't support drift detections
        
        NOT_CHECKED
    - - Corrective action to have sync
      - provide
        
        configuration consistency
        
        successful stack operations
- - - - view stack templates
      - create stacks
      - delete stacks
  - - - allows CF to make calls to resources in a stack on the user’s behalf
      - if specified, CF uses that role for all operations
- - - - except the one with status
        
        DELETE_IN_PROGRESS
        
        DELETE_COMPLETE
      - sets it for any nested stacks belonging to that stack as well
- - - - The AutoScalingReplacingUpdate and AutoScalingRollingUpdate policies apply only when you do one or more of the following:
        
        Change the Auto Scaling group’s AWS::AutoScaling::LaunchConfiguration
        
        Change the Auto Scaling group’s VPCZoneIdentifier property
        
        Change the Auto Scaling group’s LaunchTemplate property
        
        Update an Auto Scaling group that contains instances that don’t match the current LaunchConfiguration.
      - The AutoScalingScheduledAction policy applies when you update a stack that includes an Auto Scaling group with an associated scheduled action.
