p6-barrier
Project description
P6Barrier is an AWS CDK Construct that deploys a Custom Resource which
will poll until AWS Lambda Function isReady returns true. Ideal for running
code AFTER an RDS or EKS is ready.

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
)
