ELBs Should Work Whether or Not ACM Is Available

[ferricoxide]

Problem Description:

Amazon Certificate Manager (ACM) is not available for use in all regions/partitions. In these regions/partitions, it will be necessary to use Identity and Access Management (IAM) to host SSL certificates used for ELB-based SSL-termination. To maximize portability, ELB templates should allow use of either ACM- or IAM-hosted SSL certificates.

Expected Behavior:

ELBs support SSL-termination whether ACM is available for use in a given region/partition.

Actual Behavior:

ELBs do not currently support SSL-termination when ACM is unavailable for use in a given region/partition.

Affected Components

The following templates need remediation:

• make_sonarqube_ELBv1.tmplt.json
• make_sonarqube_ELBv2.tmplt.json

Fix recommendation:

Add a Condition{} and Parameters{} components and associated logic within the Resources{} sections to support selection of ACM- or IAM-hosted SSL certificates when launching an ELB template.
