0.5.0 (2022-11-30)

Changes

  • Upgraded control plane shared library dependency to v0.39.0, which requires 6 Elastic IP addresses for the subnets of the created VPC. With the default AWS VPC EIPs quota set to 5 per region, users may need to request for more quota when deploying the Aggregate Service or decrease the number of subnets created for the aggregation service VPC. To stay within the default quota you can decrease the number of subnets, by setting vpc_availability_zones = ["a","b","c","d","e"] in your <name>.auto.tfvars

  • Addressed both security issues by uprading the control plane shared library dependency.
