A collection of configuration elements.

Example

declare const vpc: ec2.Vpc;
declare const instanceType: ec2.InstanceType;
declare const machineImage: ec2.IMachineImage;

new ec2.Instance(this, 'Instance', {
  vpc,
  instanceType,
  machineImage,

  // Showing the most complex setup, if you have simpler requirements
  // you can use `CloudFormationInit.fromElements()`.
  init: ec2.CloudFormationInit.fromConfigSets({
    configSets: {
      // Applies the configs below in this order
      default: ['yumPreinstall', 'config'],
    },
    configs: {
      yumPreinstall: new ec2.InitConfig([
        // Install an Amazon Linux package using yum

      config: new ec2.InitConfig([
        // Create a JSON file from tokens (can also create other files)
        ec2.InitFile.fromObject('/etc/stack.json', {

          stackName: Stack.of(this).stackName,
