AWSTemplateFormatVersion: "2010-09-09"
Description: >-
  HyperFrames arm64 video renderer: the render handler as a container image, invoked for plan and
  renderChunk. Nested in template.yaml when VideoImageUri is set; plain CloudFormation, because `sam deploy`
  demands an image repository for any top-level image function, even one whose Condition is false.

Parameters:
  ProjectName:
    Type: String
  ImageUri:
    Type: String
  RenderBucket:
    Type: String
  MemorySize:
    Type: Number
  Timeout:
    Type: Number
  ReservedConcurrency:
    Type: Number
  ChromeSource:
    Type: String

Conditions:
  HasReservedConcurrency: !Not [!Equals [!Ref ReservedConcurrency, -1]]
