Certificate unavailable when creating RStudio from another AWS account

[BoPeng]

We have successfully set up RStudio for our SWB installation on us-east-2. However, we have multiple AWS account associated with this installation. When users from other accounts create an RStudio workspace, an error message would appear showing certificate not found.

The failure happens when the instance tries to create an ALB which tries to access the certificate from another account, although in this case, a loadbalancer already exists on the root account that supports another RStudio instance.

Does the RStudio/ALB configuration support multiple accounts? If so, how can i get around of this problem?

I got around this problem by creating a separate certificate for the user. It is a bit tricky because the DNS entry has to be manually added to the Hosted zone of the root account.

Then separate configurations need to be created for each user.
