AWS CDK Developer Preview

You can think of the CDK as a cloud infrastructure “complier”. It provides a set of high-level class libraries, called Constructs, that abstract AWS cloud resources and encapsulate AWS best practices. Constructs can be snapped together into object-oriented CDK applications that precisely define your application infrastructure and take care of all the complex boilerplate logic. When you run your CDK application, it is compiled into a CloudFormation Template, the “assembly language” for AWS cloud infrastructure.

If you wan to add element in existing list - use nested joins:

ExternalBastionSecurityGroups - List<AWS::EC2::SecurityGroup::Id>
SecurityGroupsList            - List<AWS::EC2::SecurityGroup::Id>
Outputs.BastionSecurityGroup  - AWS::EC2::SecurityGroup::Id

SecurityGroupsList: !Join
  - ','
  - - !GetAtt [ securitygroups, Outputs.BastionSecurityGroup ]
    - !Join [ ',', !Ref ExternalBastionSecurityGroups ]

There are couple issues with push agent functionality:

— by default wrapper.ntservice.interactive setting in the buildAgent/launcher/conf/wrapper.conf configuration file is set to true — this brings to error during agent installation with psexec:


in the push agent logs:

bootstrapper.exe exited on MY_AGENT_HOST_IP with error code 255.
Remote agent installation failed: Command 'D:\:\teamcity\temp___5060497447753492559\cli-wrapper.exe D:\teamcity_data\system\pluginData\psexec\psexec.exe /accepteula \\MY_AGENT_HOST_IP -e -h -u MY_USER -p ********** -c -f D:\teamcity\temp___5612841585882618839\bootstrapper.exe bootstrap -u MY_TC_MASTER_HOST – bin\install.bat MY_TC_MASTER_HOST C:\\BuildAgent 27f25fcd78b2812602f9a14ea6756bae' was executed with error message(s): Execution error. Return code=255


in the windows event logs on agent host:

The TeamCity Build Agent service is marked as an interactive service. However, the system is configured to not allow interactive services. This service may not function properly.

— it would be good to determine if push agent functionality used to install agent on EC2 host and set wrapper.ntservice.dependency.1=Ec2Config setting of the buildAgent/launcher/conf/wrapper.conf configuration file. As mentioned in manual (https://confluence.jetbrains.com/display/TCD9/Setting+up+and+Running+Additional+Build+Agents#SettingupandRunningAdditionalBuildAgents-BuildAgentasaWindowsService). Or provide corresponding configuration option in the Agent Push preset configuration dialog

— to simplify agent push configuration on the AWS please add note to manual about 445 port that should be configured in the AWS::EC2::SecurityGroup attached to build agent host. This allow to communicate psexec from TeamCity server host with build agent host
