Construct AliasConfigurationCert is created with a literal unique name by the CloudfrontWebDistribution Construct

[winjer]

If you create more than one CloudfrontWebDistribution that has a certificate associated with it in a single stack then you get the error:

Error: There is already a Construct with name 'AliasConfigurationCert' in Stack

This looks like it is because of this line:

    certificatemanager.Certificate.fromCertificateArn(scope, 'AliasConfigurationCert', acmCertRef),

in web_distribution.ts.

Reproduction Steps

Create two CloudFrontWebDistributions in one stack.

It looks like this can be avoided by using viewerCertificate instead of aliasConfiguration and that this is indeed preferable, so this is probably a documentation bug instead?

Hey @winjer,

It's a mistake on my part when I added backwards compatibility from the deprecated aliasConfiguration. I'm making a PR to fix it for the next release.

Sorry to have to force you to switch to viewerCertificate in the meantime.

[winjer]

I'm happy to use viewerCertificate - it looks like that's a better choice anyway to be honest!

Thanks for being understanding. The aws-cloudfront package is still marked as experimental, but it wasn't my intention to break aliasConfiguration 😄
