AWS tips

Amazon CloudWatch permet de surveiller les journaux des instances Amazon EC2, sans nécessiter de modifications de code. Les utilisateurs peuvent suivre les erreurs dans les journaux de leurs applications et recevoir des notifications lorsque ces erreurs dépassent un seuil prédéfini.

AWS CLI

AWS CLI est une interface de ligne de commande qui permet aux utilisateurs d'interagir avec les services Amazon Web Services (AWS) via la ligne de commande au lieu d'utiliser l'interface utilisateur graphique. Avec AWS CLI, les utilisateurs peuvent gérer efficacement les ressources, configurer les services et automatiser les tâches dans AWS. Fournit des commandes pour accéder et gérer une large gamme de services AWS, tels que EC2, S3, RDS, Lambda, etc. Avec l'AWS CLI, les utilisateurs peuvent écrire des scripts et des commandes personnalisés pour automatiser des tâches répétitives ou complexes dans AWS.

     $ aws configure set default.region us-west-2

add-model

ADD-MODEL()                            ADD-MODEL()




NAME

    add-model -


DESCRIPTION

    Adds a service JSON model to the appropriate location in ~/.aws/models.

    Once the model gets added, CLI commands and Boto3 clients will be imme-

    diately available for the service JSON model provided.


    See 'aws help' for descriptions of global parameters.


SYNOPSIS

      add-model

     --service-model <value>

     [--service-name <value>]


OPTIONS

    --service-model (string) The contents of the service JSON model.


    --service-name (string) Overrides the default name used by the service

    JSON model to generate CLI service commands and Boto3 clients.


    See 'aws help' for descriptions of global parameters.


EXAMPLES

    Add a model


    The following command adds a service model from a file named ser-

    vice.json:


     aws configure add-model --service-model file://service.json


    Adding a model replaces existing commands for the service defined in

    the model. To leave existing commands as-is, specify a different ser-

    vice name to use for the new commands:


     aws configure add-model --service-model file://service.json --service-name service2

get

 Suppose you had the following config file:


     [default]

     aws_access_key_id=default_access_key

     aws_secret_access_key=default_secret_key


     [preview]

     cloudsearch=true


     [profile testing]

     aws_access_key_id=testing_access_key

     aws_secret_access_key=testing_secret_key

     region=us-west-2


    The following commands would have the corresponding output:


     $ aws configure get aws_access_key_id

     default_access_key


     $ aws configure get default.aws_access_key_id

     default_access_key


     $ aws configure get aws_access_key_id --profile testing

     testing_access_key


     $ aws configure get profile.testing.aws_access_key_id

     testing_access_key

sync

Syncs directories and S3 prefixes. Recursively copies new and updated files from the source directory to the destination. Only creates folders in the destination if they contain one or more files.

rm

rb

presign

Generate a pre-signed URL for an Amazon S3 object. This allows anyone who receives the pre-signed URL to retrieve the S3 object with an HTTP GET request. For sigv4 requests the region needs to be configured explicitly.

DependsOn


"DependsOn":"CloudWatchTransformFunctionRole"

This attribute is used to define that the creation of a specific resource follows another. I often use it if a certain resource requires an IAM role or CloudWatch LogGroup created beforehand and I need to ensure the order is followed. Otherwise, the CloudFormation template may fail with an error message that the ARN can not be referenced.

Intrinsic Fn

The term "Intrinsic Fn" refers to the intrinsic functions in AWS CloudFormation. Intrinsic functions are built-in functions that allow you to perform various operations within your CloudFormation templates. These functions are used to dynamically define values or conditionally control the resources being created. There are several intrinsic functions available in CloudFormation, such as `Fn::Ref`, `Fn::Sub`, `Fn::Join`, `Fn::If`, and `Fn::Not`. - `Fn::Ref` is used to get the value of the specified parameter or resource. - `Fn::Sub` is used to substitute variables within a string with their corresponding values. - `Fn::Join` is used to concatenate multiple values together. - `Fn::If` is used to conditionally create resources or specify values based on a condition. - `Fn::Not` is used to negate a condition. These intrinsic functions can be used to make your CloudFormation templates more dynamic and flexible by allowing you to reference and manipulate values based on different conditions or inputs.

Outputs

The optional Outputs section declares output values that you can import into other stacks (to create cross-stack references), return in response (to describe stack calls), or view on the AWS CloudFormation console. For example, you can output the S3 bucket name for a stack to make the bucket easier to find.

Rules

The optional Rules section validates a parameter or a combination of parameters passed to a template during a stack creation or stack update. To use template rules, explicitly declare Rules in your template followed by an assertion. Use the rules section to validate parameter values before creating or updating resources.


Each template rule consists of two properties:


Rule-specific intrinsic functions


To define a rule condition and assertions, use rule-specific intrinsic functions, which are functions that can only be used in the Rules section of a template. You can nest functions, but the final result of a rule condition or assertion must be either true or false.

You can use the following rule-specific intrinsic functions to define rule conditions and assertions:

Examples


Conditionally verify a parameter value

In the following example, the two rules check the value of the InstanceType parameter. Depending on the value of the environment parameter (test or prod), the user must specify a1.medium or a1.large for the InstanceType parameter. The InstanceType and Environment parameters must be declared in the Parameters section of the same template.


Rules:

 testInstanceType:

  RuleCondition: !Equals 

   - !Ref Environment

   - test

  Assertions:

   - Assert:

     'Fn::Contains':

      - - a1.medium

      - !Ref InstanceType

    AssertDescription: 'For a test environment, the instance type must be a1.medium'

 prodInstanceType:

  RuleCondition: !Equals 

   - !Ref Environment

   - prod

  Assertions:

   - Assert:

     'Fn::Contains':

      - - a1.large

      - !Ref InstanceType

    AssertDescription: 'For a production environment, the instance type must be a1.large'

Metadata

AWS::CloudFormation::Interface is a metadata key that defines how parameters are grouped and sorted in the AWS CloudFormation console. When you create or update stacks in the console, the console lists input parameters in alphabetical order by their logical IDs. By using this key, you can define your own parameter grouping and ordering so that users can efficiently specify parameter values. For example, you could group all EC2-related parameters in one group and all VPC-related parameters in another group.
