Overview

This package deals with the communication with AWS-Batch and adopting its APIs to the flyte-plugin model.

Example (NewContainerResources) 
defaultValues := []*core.Resources_ResourceEntry{
	{
		Name:  core.Resources_CPU,
		Value: "1",
	},
}

overrideValues := []*core.Resources_ResourceEntry{
	{
		Name:  core.Resources_CPU,
		Value: "3",
	},
}

res := newContainerResources(context.TODO(), nil, overrideValues, defaultValues)
fmt.Printf("Computed Cpu: %v\n", res.Cpus)

Output:

Computed Cpu: 3
