AWS App Parameters

The following parameters are available for configuring your Convox applications on Amazon Web Services (AWS). These parameters allow you to customize and optimize the behavior of your applications running on the AWS platform.

Parameters

Parameter	Description
BuildLabels	Specifies Kubernetes node selector labels for build pods
BuildCpu	Sets the CPU request for build pods in millicores
BuildMem	Sets the memory request for build pods in megabytes

Warning: When configuring BuildLabels, ensure that the specified labels match those defined in the additional_build_groups rack parameter. If the labels don’t match any existing build node groups, build pods will remain in a pending state indefinitely, preventing builds from completing.

These application-specific parameters complement the rack-level configuration available through Rack Parameters, providing fine-grained control over your application deployments.

Setting Parameters

To set an app parameter, use the following command:

$ convox apps params set parameterName=value -a appName

For example, to set the BuildLabels parameter:

Setting BuildLabels... OK
