The following is a full reference for all the fields that can be set for a web service in porter.yaml.

  • autoscaling - the autoscaling configuration for the service.
    • enabled - whether autoscaling is enabled or not.
    • minInstances - the minimum number of instances to run.
    • maxInstances - the maximum number of instances to run.
    • cpuThresholdPercent - the CPU threshold percentage to trigger autoscaling at.
    • memoryThresholdPercent - the memory threshold percentage to trigger autoscaling at.
  • domains - the list of custom domains for the service, if the service is exposed publicly.
    • name - the name of the domain.
  • private - whether the service is private or not.
  • healthCheck - the health check configuration for the service.
    • enabled - whether the health check is enabled or not.
    • httpPath - the path to check for the health check.
  • ingressAnnotations - the ingress annotations to apply for the service.
  • pathRouting - the list of URL paths to service port mappings, if path-based routing is enabled. Note that a path must be specified for the default port (set in services.port). If routing to a port on a different service, the port must be exposed on that service (either as the default port or through a path routing rule).
    • path - the URL path.
    • port - the port to route to.
    • appName - (optional) the name of the application to route to (as it appears in the dashboard). Defaults to the application of the current service.
    • serviceName - (optional) the name of the service to route to (as it appears in the dashboard). Defaults to the current service. Must be specified if appName is set.
  • rewriteCustomPaths - when path routing is enabled, whether to rewrite custom paths to the root path. Defaults to true.
