Description

When deploying UDS Core Base to EKS, we can use annotations to populate certificates from Amazon’s AWS Certificate Manager (ACM) on the ELBs provisioned by Istio (see here and here).

Unfortunately, this does not work if an entry in the Gateway's servers spec contains tls -- likely a result of the conflicting certs provided for *.uds.dev.

By exposing the option of enabling/disable TLS via a variable, we can opt to disable it, and therefore enable annotation-based cert management.

Type of change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Other (security config, docs update, etc)
