cdk-ssm-serde

For serializing and deserializing CDK constructs to and from SSM parameters

Supported resources

• aws-eks.Cluster
• aws-route53.HostedZone

Purpose

To manage dependencies between projects that use the same AWS accounts, in such a way that they can be promoted through environments without hard coded configuration.

Example

// Create your HostedZone
const hostedZone = new route53.HostedZone(stack, 'HostedZone', {
    zoneName: 'example.com',
});

// Put a reference to it into SSM
route53SsmSerde.HostedZone.toSsm(stack, {
    parameterPrefix: '/myhostedzone',
    resource: hostedZone,
});

Then, in a different stack, maybe even in a different repo in a different project, but deployed to the same AWS account:

const hostedZone = route53SsmSerde.HostedZone.fromSsm(stack, 'HostedZone', {
    parameterPrefix: '/myhostedzone',
});

Releasing a new version

• (Almost certainly) be on latest main, with no unpublished changes
• Run npm version (patch|minor|major) as appropriate
• Run git push and git push origin TAG where TAG is the tag that npm version just created

The tag triggers a Github Actions job to publish to npm.
