How to specify multiple import and export paths when creating FSX for Lustre filesystem in CDK

[yashwanthkp]

Hi,

I am creating a new FSXFileSystem for Lustre. I want to setup auto import/export from 2 different S3 buckets on the filesystem. The LustreConfiguration in CDK takes only a string which lets me specify only a single bucket. How do I setup export/import on multiple buckets on creation?

const fsxLustreFileSystem = new fsx.LustreFileSystem(
            this,
            `FsxFileSystem`,
            {
                lustreConfiguration: {
                    deploymentType: fsx.LustreDeploymentType.PERSISTENT_2,
                    exportPath: S3Bucket.s3UrlForObject(),
                    importPath: S3Bucket.s3UrlForObject(),
                },
                storageCapacityGiB: 1200,
                vpc: vpc,
                vpcSubnet: vpc.privateSubnets[0],
                securityGroup: securityGroup,
            }
        );

It looks to me like CloudFormation doesn't allow for configuring multiple imports and exports, see their docs here.

CDK will be limited by what CloudFormation can provide here, if you need a way to work around this I would recommend looking into custom resoures - maybe AwsCustomResource could help you out here if you can make a simple API call to set this

Else, I would recommend creating an issue on the CloudFormation Coverage Roadmap if one doesn't exist already 🙂
