Summary

Use this to wait for an RDS or for that matter anything to become ready.

This deploys a Custom Resource which is obviously backed by an AWS Lambda. This lambda calls the lambda with Arn functionArn.

This function should return the string 'True' if the resource is ready. Otherwise 'False'. This function must be provided by you and is custom for your needs.

This is abstracted from @aws-cdk/aws-eks/cluster.ts where a Custom Resource which makes an SSM Parameter is used as a barrier for Resources to depend on until the EKS Cluster is ready for Helm to be run via an addHelmChart

Usage

Example 1 - External Lambda

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from p6_barrier import P6Barrier

P6Barrier(self, "p6-barrier",
    name="some_useful_name",
    dependencies=[dep1, dep2],
    function_arn="functionArn"
)

Example 2 - CDK Lambda (same stack)

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from p6_barrier import P6Barrier

is_ready = lambdajs.NodejsFunction(self, "isReady",
    timeout=Duration.minutes(15),
    tracing=lambda_.Tracing.ACTIVE
)

P6Barrier(self, "p6-barrier",
    name="some_useful_name",
    dependencies=[dep1, dep2],
    function_arn=is_ready.function_arn
)
