Deployment plan types¶

AWS Step Functions have a lot of great integrations with other AWS services ex Lambda and CodeBuild. However, to use AWS Step Functions as a deployment pipeline it was missing some important features, that is why we built some additional State Types.

Attini::Deploy::DeploymentPlan AttiniCfn¶

Type: AttiniCfn
Properties:
  Template: String
  StackName: String
  ConfigFile: String
  Parameters: Map<String,String>
  StackRoleArn: String
  ExecutionRoleArn: String
  Region: String
  OutputPath: String
  Variables: Map<String,String>
  Action: String

AttiniCfn will create, update or delete a CloudFormation stack.

See more information about the configuration options here.

Note

If the stack is in state “ROLLBACK_COMPLETE” and you run the deployment plan, the stack will be deleted and recreated. The “ROLLBACK_COMPLETE” state only occurs after a failed creation, and the rollback has deleted all the resources in the stack.

Template

Type: String

This has to point towards a CloudFormation template stored in S3. It can either be a URL to a public template, or a reference to a template in the distribution. If the template is in the distribution, the reference has to start with a “/”, ex “/path/to/my/template.yaml”

Required: Conditional | Required unless it’s configured in the ConfigFile.

Default: None

StackName

Type: String

AWS API compatibility: This property is passed directly to the StackName property of the CreateStack or UpdateStack API call.

Required: Conditional | Required unless it’s configured in the ConfigFile.

Default: None

ConfigFile

Type: String

This is a reference to a JSON or a YAML file in the distribution. The reference has to start with a “/”, ex “/path/to/my/parameters.json”

Note

Public HTTPS endpoints ex https://path/to/my/parameters.json does not work for configuration files.

Find more info CloudFormation configuration

Required: No

Default: None

Parameters
Type: Map<String, String>

The CloudFormation parameters, find more info CloudFormation configuration.

Required: No

Default: None

StackRoleArn
Type: String

Arn of the StackRole, find more info here: AWS CloudFormation service role

Note

This IAM Role has to be in the same AWS Account that the CloudFormation stack is deployed in, so if “ExecutionRoleArn” is in a different AWS Account this “StackRoleArn” has to be in the same account as the “ExecutionRoleArn”. If the “StackRoleArn” is in a different AWS Account then the “ExecutionRoleArn” you will receive a “Cross-account pass role is not allowed.” error.

Find more information about the security aspects of StackRoles here.

Required: Conditional

If the parameter “UseAdministratorAccessForDeployingCloudformation” in attini-setup CloudFormation stack is false, this parameter or ExecutionRoleArn is required.

Default: None

ExecutionRoleArn
Type: String

The role that you want to be assumed when the Attini Framework deploys the CloudFormation stack. This can be useful if you are:

Applying least privilege policies without using Stack roles

Doing cross-account deployments

The ExecutionRole have to trust the default role arn:aws:iam::{AccountId}:role/attini/attini-action-role-{Region} so that it can be assumed.

Example trust relationship policy:
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::111111111111:role/attini/attini-action-role-eu-west-1"
        ]
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
Note

If you configure an execution role in another account or region the Attini Framework will use a polling pattern to verify the state of the stack, this makes the deployment plan execution slower and it can lead to throttling issues if it’s used a lot.

Find more information about the security aspects of ExecutionRoles here.

Required: No

Default: arn:aws:iam::{AccountId}:role/attini/attini-action-role-{Region}

Region
Type: String

Configure the region you want the CloudFormation stack in.

Note

If you configure a Region other then the current region the Attini Framework will use a polling pattern to verify the state of the stack, this makes the deployment plan execution slower and it can lead to throttling issues if it’s used a lot.

Required: No

Default: Current region

OutputPath
Type: String

If you need an extra level of separation for your output, you can use OutputPath. This is useful if you need to have multiple output sections from one step, example when you use AttiniMap type.

If you for example have a State name buzz and an OutputPath: foo the output payload will look like this:
{
  "output": {
    "buzz": {
      "foo": {
        "OutputKey": "OutputValue"
      }
    }
  }
}
Required: No

Default: None

Variables
Type: Map<String,String>

If your step has a ConfigFile configured, you can use Variables to pass values from your deployment plan payload into the file.

If you for example have an AttiniCfn State with the following config:
StateName:
  Type: AttiniCfn
  Properties:
    Template: /ecs-service.yaml
    ConfigFile: /ecs-config.yaml
    Variables:
      Environment: !Ref AttiniEnvironmentName
      DatabasePort.$: $.output.Database.Port
      StackRoleArn.$: $.output.StackRoles.EcsStackRole
    StackName: ecs-service
Your ConfigFile can look like this:
stackRoleArn: ${StackRoleArn}
parameters:
  ServiceName: ${Environment}-my-ecs-service
  DatabasePort: ${DatabasePort}
Note

By using Variables you can replace or manipulate any AttiniCfn configuration except for the ConfigFile path.

Required: No

Default: None
Action
Type: String

Specify if the stack should be created/updated or deleted.

Allowed values: Deploy | Delete

Required: No

Default: Deploy

Attini::Deploy::DeploymentPlan AttiniLambdaInvoke¶

Type: AttiniLambdaInvoke
Parameters:
  FunctionName: String

AttiniLambdaInvoke will call a Lambda function while preserving the payload for subsequent steps. This is an abstraction of the Amazon state language Lambda integration and all parameters are supported.

By default, the entire payment plan payload will be passed as input to the Lambda function. This can be overridden by setting the Payload parameter.

Example

AWSTemplateFormatVersion: "2010-09-09"
Transform:
  - AttiniDeploymentPlan
  - AWS::Serverless-2016-10-31

Resources:

  ExampleDeploy:
    Type: Attini::Deploy::DeploymentPlan
    Properties:
      DeploymentPlan:
        StartAt: InvokeMyLambda
        States:
          InvokeMyLambda:
            Type: AttiniLambdaInvoke
            Parameters:
              FunctionName: some-lambda-function
            End: true

Attini::Deploy::DeploymentPlan AttiniMap¶

Note

Experimental feature!

Type: AttiniMap
ItemsPath: String
MaxConcurrency: Number
Iterator:
  StartAt: StateName
  States:
    StateName:
      Type: AttiniCfn

This is an abstraction of the Amazon state language Map that help you use AttiniCfn within a Map.

In an AttiniMap you AttiniCfn will need to have OutputPath configured.

For an example, see example-ecs-platform.

ATM: It requires a list of S3 Objects keys that is served as input for each iteration. We are working on improving AttiniMap to make it more user-friendly.

Note

Experimental feature!

Attini::Deploy::DeploymentPlan AttiniMergeOutput¶

Type: AttiniMergeOutput

Some AWS StepFunction types return a list instead of a object, example Parallel or Map.

To make the payload easy to work with the merge step kan merge all the data in the list into one object.

Note

The merge will remove duplicates in all lists in the payload.

Example

AWSTemplateFormatVersion: "2010-09-09"

Attini::Deploy::DeploymentPlan AttiniRunnerJob¶

Note

AttiniRunnerJob is in beta testing

Type: AttiniRunnerJob
Properties:
  Runner: String
  Commands:
    - String

The AttiniRunnerJob is a quick and cost-efficient way to run shell commands using a container.

Find detailed information about the Attini::Deploy::Runner type here.

Find detailed information about the runners architecture here.

Runner

Type: String

Reference a Attini::Deploy::Runner recourse, find more information here.

Required: Yes

Commands

Type: List<String>

List of shell commands that runs the job.

These commands are run with set -eo pipefail configuration so that they fail quickly. To revert this configuration (and ignore errors in your scrips), begin your commands with the line: set +eo pipefail.

Note

These strings can NOT integrate with the payload through Amazon state language using the $. syntax or its intrinsic functions.

If you need these commands to integrate with the payload, see Attini runner input and output.

Required: Yes
