示例1: RegisterTaskDefinitionIfNeeded
// RegisterTaskDefinitionIfNeeded checks if a task definition has already been
// registered via the provided cache, and if so returns it.
// Otherwise, it registers a new one.
//
// This exists to avoid an explosion of task definitions for automatically
// registered inputs.
func (client *ecsClient) RegisterTaskDefinitionIfNeeded(
request *ecs.RegisterTaskDefinitionInput,
taskDefinitionCache cache.Cache) (*ecs.TaskDefinition, error) {
if request.Family == nil {
return nil, errors.New("invalid task definitions: family is required")
}
taskDefResp, err := client.DescribeTaskDefinition(aws.StringValue(request.Family))
// If there are no task definitions for this family OR the task definition exists and is marked as 'INACTIVE',
// register the task definition and create a cache entry
if err != nil || *taskDefResp.Status == ecs.TaskDefinitionStatusInactive {
return persistTaskDefinition(request, client, taskDefinitionCache)
}
tdHash := client.constructTaskDefinitionCacheHash(taskDefResp, request)
td := &ecs.TaskDefinition{}
err = taskDefinitionCache.Get(tdHash, td)

示例2: persistTaskDefinition
// persistTaskDefinition registers the task definition with ECS and creates a new local cache entry
func persistTaskDefinition(request *ecs.RegisterTaskDefinitionInput, client *ecsClient, taskDefinitionCache cache.Cache) (*ecs.TaskDefinition, error) {
resp, err := client.RegisterTaskDefinition(request)
if err != nil {

err = taskDefinitionCache.Put(tdHash, resp)
if err != nil {
log.WithFields(log.Fields{
"error": err,
}).Warn("Could not cache task definition; redundant task definitions might be created")
// We can keep going even if we can't cache and operate mostly fine
}
return resp, err
