Set ulimit in container definition prop

[ambethell]

I need to set the ulimits on a fargate ECS task - (I'm using the Java CDK).

From what I can tell I should be able to set this on the fargate task definition - but I cannot see how to do this using the CDK. Do I need to add an extension to the fargateTaskDefinition?

I see 'ContainerDefinition' has a public method for setting uLimit - however the ContainerDefinitionOptions.builder() does not appear to provide methods to set this.

Both v1 / v2 documentation dont provide this - https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ecs.ContainerDefinitionOptions.html

Any pointers?

Thanks!

I'd like to bump this. Right now it's not clear how to properly implement ulimits via the CDK.

As mentioned in the OP you can currently do this with ContainerDefinition.addUlimits(). You should be able to easily add this method on to where you add the container to your task definition.

That said, we should still be able to support it as a direct prop. I'm going to convert this to a feature request to track that 🙂
