Description

Encryption in transit is an important feature for service meshes. App Mesh support's for it is still for preview channel only (see ref 1). The virtual node Terraform resource does not provide the option at the moment.

New or Affected Resource(s)

• aws_appmesh_virtual_node

Proposed interface

According to the documentation, a certificate should be created somewhere (ACM), and a tls object should be added to the listener of each virtual node. This tls object has two options: a mode and reference to a ACM certificate.

"tls": {
            "mode": "STRICT",
            "certificate": {
                "acm": {
                    "certificateArn": "${CERTIFICATE_ARN}"
                }
            }
        }

@brunocous I had been looking at the App Mesh preview channel in #9468 but put this on pause as the features started to move into the release channel.
I'm not sure what plans are for supporting preview channels in general.
