Description: '(SO0089) - customizations-for-aws-control-tower Solution. Version: v2.6.0'
Parameters:
PipelineApprovalStage:
Description: Do you want to add a manual approval stage to the Custom Control Tower Configuration Pipeline?
AllowedValues:
- 'Yes'
- 'No'
Default: 'No'
Type: String
PipelineApprovalEmail:
Description: (Not required if Pipeline Approval Stage = 'No') Email for notifying that the CustomControlTower pipeline is waiting for an Approval
Type: String
CodePipelineSource:
Description: Which AWS CodePipeline source provider do you want to select?
AllowedValues:
- 'Amazon S3'
- 'AWS CodeCommit'
Default: 'Amazon S3'
Type: String
CodeCommitRepositoryName:
Description: Name of the CodeCommit repository that contains custom Control Tower configuration. The suffix .git is prohibited.
Default: custom-control-tower-configuration
Type: String
AllowedPattern: ^[\w\.-]+
CodeCommitBranchName:
Description: Name of the branch in CodeCommit repository that contains custom Control Tower configuration.
Default: main
Type: String
ExistingRepository:
Description: Are you using an existing CodeCommit repository that already contains custom Control Tower configuration?
Default: 'No'
Type: String
AllowedValues:
- 'Yes'
- 'No'
RegionConcurrencyType:
Description: Select the the concurrency type of deploying StackSets operations in Regions.
Default: 'PARALLEL'
Type: String
AllowedValues:
- 'PARALLEL'
- 'SEQUENTIAL'
MaxConcurrentPercentage:
Description: The maximum percentage of accounts in which to perform this operation at one time.
Default: 100
Type: String
FailureTolerancePercentage:
Description: The percentage of accounts, per Region, for which this stack operation can fail before AWS CloudFormation stops the operation in that Region.
Default: 10
Type: String
EnforceSuccessfulStackInstances:
Description: By default, CfCT's deployment pipeline defers to Stack Sets to report failures based on the combination of concurrency and fault tolerance you choose. Setting this parameter to true will consider a Stack Set deployment that contains failed stack instance deployments to be a failure in the deployment pipeline, regardless of fault tolerance you specify. This allows for you to specify 100% concurrency, but stop the pipeline post-deployment if stack instances fail to deploy.
Default: false
Type: String
AllowedValues:
- true
- false
