EFS & BucketDeployment & VPC times out

[macutko]

I have the following config

  const vpc = new Vpc(this, 'web-vpc', {
                vpcName: `${props.envName}-web-vpc`,
                createInternetGateway: true,
                enableDnsHostnames: true,
                enableDnsSupport: true,
                natGateways: 0,
                subnetConfiguration: [
                    {
                        cidrMask: 26,
                        name: 'privateIsolated',
                        subnetType: SubnetType.PRIVATE_ISOLATED
                    }
                ]
            });

vpc.applyRemovalPolicy(RemovalPolicy.DESTROY);

new BucketDeployment(this, 'BucketDeployment', {
    destinationBucket: bucket,
    distribution: distribution,
    distributionPaths: ['/*'], // Invalidate the CloudFront cache on upload
    sources: [
        Source.asset(
            path.join(__dirname, '..', '..', '..', '..', 'dist', 'apps', 'web')
        )
    ],
    useEfs: true,
    vpc,
    memoryLimit: 1024,
    retainOnDelete: false
});

I am uploading a 500+mb page. The issue seems to be with my VPC config. The lambda responsible for uploading to the s3 times out on the s3 command and I tried this with 5000MB memroy as well. The issue is almost certainly (imo) with the VPC config - I am guess the vpc has no access to the s3.

I cannot find a working example in the docs. Did anybody manage to get this working?
