Shiny App Embed: HTTP iframe conflicting with HTTPS

[nicklucius]

@tomschenkjr - it looks like AWS has a UI for adding HTTPS, but it only works with EC2 instances that use Elastic Load Balancing or CloudFront--I'm not sure that we use either: https://aws.amazon.com/blogs/aws/new-aws-certificate-manager-deploy-ssltls-based-apps-on-aws/.

If we create our own certificate, we'll still might get blocked by browsers: https://www.r-bloggers.com/shiny-https-securing-shiny-open-source-with-ssl/

New GitHub Pages are HTTPS only: https://github.com/blog/2186-https-for-github-pages

It looks like a third party certificate might be the only way.

Ok, we’ll proceed without a certificate for now. There is a nuance in the gh-pages, you can turn-off the forcing to HTTPS. But, by default, HTTPS is enabled (but you don’t have to visit it). Right now, I’m forcing to HTTPS.

Here are some instructions on a Shiny app and a certificate https://www.r-bloggers.com/shiny-https-securing-shiny-open-source-with-ssl/

[tomschenkjr]

It appears the HTTPS enforce is only for the index page. However, it is not enforced by default when going to the challenge/ page. Thus, I've updated the links to point to http for the app to avoid the mixed-content errors.

When we get a chance, let's grab a certificate and post it to the EC2 instance. But, at least, it's not a pressing matter.

[tomschenkjr]

@nicklucius - for @ThorSean upcoming article, he's hitting some HTTPS mixed-content issues. I don't think we can sidestep it this time. Can you take a look at adding a token. This may be a viable, free option.

Let me know if this is shaping-up to be a complete pain.

[nicklucius]

@tomschenkjr - no problem, I'll look into this.

[nicklucius]

@tomschenkjr - I ran into a problem with Let's Encrypt. They blacklist EC2 domain names. Here is my error when generating a certificate:

Error: urn:acme:error:rejectedIdentifier :: Error creating new authz :: Policy forbids issuing for name

And here is a discussion that confirms this is a problem for EC2 domains.

If we could get a *.cityofchicago.org domain that points to ec2-52-54-246-48.compute-1.amazonaws.com, then I could get an SSL certificate installed. Alternatively, we could get a second EC2 instance set up mirroring the first, configure load balancing, and then use AWS's own HTTPS manager. I can't think of any other way.
