Implements IFileSetProducer

Extends ShellStep

Run a script as a CodeBuild Project.

The BuildSpec must be available inline--it cannot reference a file on disk. If your current build instructions are in a file like buildspec.yml in your repository, extract them to a script (say, build.sh) and invoke that script as part of the build:

new pipelines.CodeBuildStep('Synth', {
   commands: ['./build.sh'],
});

Example

new pipelines.CodePipeline(this, 'Pipeline', {
  synth: new pipelines.CodeBuildStep('Synth', {
    input: pipelines.CodePipelineSource.connection('my-org/my-app', 'main', {
      connectionArn: 'arn:aws:codestar-connections:us-east-1:222222222222:connection/7d2469ff-514a-4e4f-9003-5ca4a43cdc41', // Created using the AWS console * });',
    }),
    commands: [
      // Commands to load cdk.context.json from somewhere here
      '...',
      'npm ci',
      'npm run build',
      'npx cdk synth',
      // Commands to store cdk.context.json back here
      '...',
    ],
    rolePolicyStatements: [
      new iam.PolicyStatement({
        actions: ['sts:AssumeRole'],
        resources: ['*'],
        conditions: {
          StringEquals: {
            'iam:ResourceTag/aws-cdk:bootstrap-role': 'lookup',
          },
        },
      }),
    ],
  }),
});

commands

Type: string[]

Commands to run.

dependencies

Type: Step[]

Return the steps this step depends on, based on the FileSets it requires.

dependencyFileSets

Type: FileSet[]

The list of FileSets consumed by this Step.

env

Type: { [string]: string }

Environment variables to set.

envFromCfnOutputs

Type: { [string]: StackOutputReference }

Set environment variables based on Stack Outputs.

grantPrincipal

Type: IPrincipal

The CodeBuild Project's principal.

id

Type: string

Identifier for this step.

inputs

Type: FileSetLocation[]

Input FileSets.

A list of (FileSet, directory) pairs, which are a copy of the input properties. This list should not be modified directly.

installCommands

Type: string[]

Installation commands to run before the regular commands.

For deployment engines that support it, install commands will be classified differently in the job history from the regular commands.

isSource

Type: boolean

Whether or not this is a Source step.

What it means to be a Source step depends on the engine.

outputs

Type: FileSetLocation[]

Output FileSets.

A list of (FileSet, directory) pairs, which are a copy of the input properties. This list should not be modified directly.

project

Type: IProject

CodeBuild Project generated for the pipeline.

Will only be available after the pipeline has been built.

actionRole?

Type: IRole (optional, default: A role is automatically created)

Custom execution role to be used for the Code Build Action.

buildEnvironment?

Type: BuildEnvironment (optional, default: No value specified at construction time, use defaults)

Build environment.

partialBuildSpec?

Type: BuildSpec (optional, default: Contains the exported variables)

Additional configuration that can only be configured via BuildSpec.

Contains exported variables

primaryOutput?

Type: FileSet (optional)

The primary FileSet produced by this Step.

Not all steps produce an output FileSet--if they do you can substitute the Step object for the FileSet object.

projectName?

Type: string (optional, default: No value specified at construction time, use defaults)

Name for the generated CodeBuild project.

role?

Type: IRole (optional, default: No value specified at construction time, use defaults)

securityGroups?

Type: ISecurityGroup[] (optional, default: No value specified at construction time, use defaults)

subnetSelection?

Type: SubnetSelection (optional, default: No value specified at construction time, use defaults)

Which subnets to use.

timeout?

Type: Duration (optional, default: Duration.hours(1))

The number of minutes after which AWS CodeBuild stops the build if it's not complete.

For valid values, see the timeoutInMinutes field in the AWS CodeBuild User Guide.

vpc?

The VPC where to execute the SimpleSynth.

Methods

Name	Description
addOutputDirectory(directory)	Add an additional output FileSet based on a directory.
addStepDependency(step)	Add a dependency on another step.
exportedVariable(variableName)	Reference a CodePipeline variable defined by the CodeBuildStep.
primaryOutputDirectory(directory)	Configure the given output directory as primary output.
toString()	Return a string representation of this Step.

addOutputDirectory(directory)

public addOutputDirectory(directory: string): FileSet

Parameters

directory string

Returns

FileSet

Add an additional output FileSet based on a directory.

After running the script, the contents of the given directory will be exported as a FileSet. Use the FileSet as the input to another step.

Multiple calls with the exact same directory name string (not normalized) will return the same FileSet.

addStepDependency(step)

public addStepDependency(step: Step): void

Parameters

step Step

Add a dependency on another step.

exportedVariable(variableName)

public exportedVariable(variableName: string): string

Parameters

variableName string — the name of the variable for reference.

Returns

string

Reference a CodePipeline variable defined by the CodeBuildStep.

The variable must be set in the shell of the CodeBuild step when it finishes its post_build phase. Example

// Access the output of one CodeBuildStep in another CodeBuildStep
declare const pipeline: pipelines.CodePipeline;

const step1 = new pipelines.CodeBuildStep('Step1', {
  commands: ['export MY_VAR=hello'],
});

const step2 = new pipelines.CodeBuildStep('Step2', {
  env: {
    IMPORTED_VAR: step1.exportedVariable('MY_VAR'),
  },
  commands: ['echo $IMPORTED_VAR'],
});

primaryOutputDirectory(directory)

public primaryOutputDirectory(directory: string): FileSet

Parameters

directory string

Returns

FileSet

Configure the given output directory as primary output.

If no primary output has been configured yet, this directory will become the primary output of this ShellStep, otherwise this method will throw if the given directory is different than the currently configured primary output directory.

toString()

public toString(): string

Returns

string

Return a string representation of this Step.
