The AWS::Batch::ComputeEnvironment resource defines your AWS Batch compute environment. You can define MANAGED or UNMANAGED compute environments. MANAGED compute environments can use Amazon EC2 or AWS Fargate resources. UNMANAGED compute environments can only use EC2 resources. For more information, see Compute Environments in the ** .
In a managed compute environment, AWS Batch manages the capacity and instance types of the compute resources within the environment. This is based on the compute resource specification that you define or the launch template that you specify when you create the compute environment. You can choose either to use EC2 On-Demand Instances and EC2 Spot Instances, or to use Fargate and Fargate Spot capacity in your managed compute environment. You can optionally set a maximum price so that Spot Instances only launch when the Spot Instance price is below a specified percentage of the On-Demand price.
Multi-node parallel jobs are not supported on Spot Instances.
In an unmanaged compute environment, you can manage your own EC2 compute resources and have a lot of flexibility with how you configure your compute resources. For example, you can use custom AMI. However, you need to verify that your AMI meets the Amazon ECS container instance AMI specification. For more information, see container instance AMIs in the Amazon Elastic Container Service Developer Guide . After you have created your unmanaged compute environment, you can use the DescribeComputeEnvironments operation to find the Amazon ECS cluster that is associated with it. Then, manually launch your container instances into that Amazon ECS cluster. For more information, see Launching an Amazon ECS container instance in the Amazon Elastic Container Service Developer Guide .
AWS Batch doesn't upgrade the AMIs in a compute environment after it's created except under specific conditions. For example, it doesn't automatically update the AMIs when a newer version of the Amazon ECS optimized AMI is available. Therefore, you're responsible for the management of the guest operating system (including updates and security patches) and any additional application software or utilities that you install on the compute resources. There are two ways to use a new AMI for your AWS Batch jobs. The original method is to complete these steps:
- Create a new compute environment with the new AMI.
- Add the compute environment to an existing job queue.
- Remove the earlier compute environment from your job queue.
- Delete the earlier compute environment.
In April 2022, AWS Batch added enhanced support for updating compute environments. For more information, see Updating compute environments in the AWS Batch User Guide . To use the enhanced updating of compute environments to update AMIs, follow these rules:
- Either do not set the ServiceRole property or set it to the AWSServiceRoleForBatch service-linked role.
- Set the AllocationStrategy property to
BEST_FIT_PROGRESSIVEorSPOT_CAPACITY_OPTIMIZED.- Set the ReplaceComputeEnvironment property to
false.- Set the UpdateToLatestImageVersion property to
true.- Either do not specify an image ID in ImageId or ImageIdOverride properties, or in the launch template identified by the Launch Template property. In that case AWS Batch will select the latest Amazon ECS optimized AMI supported by AWS Batch at the time the infrastructure update is initiated. Alternatively you can specify the AMI ID in the
ImageIdorImageIdOverrideproperties, or the launch template identified by theLaunchTemplateproperties. Changing any of these properties will trigger an infrastructure update.If these rules are followed, any update that triggers an infrastructure update will cause the AMI ID to be re-selected. If the Version property of the LaunchTemplateSpecification is set to
$Latestor$Default, the latest or default version of the launch template will be evaluated up at the time of the infrastructure update, even if theLaunchTemplateSpecificationwas not updated.

The default value is true . To enable more properties to be updated, set this property to false . When changing the value of this property to false , no other properties should be changed at the same time.

You can't update a stack that is in the UPDATE_ROLLBACK_FAILED state. However, if you can continue to roll it back, you can return the stack to its original settings and then try to update it again.

@Stability(value=Stable) @Nullable public String getServiceRole()
For more information, see AWS Batch service IAM role in the AWS Batch User Guide .
If your account already created the AWS Batch service-linked role, that role is used by default for your compute environment unless you specify a different role here. If the AWS Batch service-linked role doesn't exist in your account, and no role is specified here, the service attempts to create the AWS Batch service-linked role in your account.
If your specified role has a path other than / , then you must specify either the full role ARN (recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide .
Depending on how you created your AWS Batch service role, its ARN might contain the
service-rolepath prefix. When you only specify the name of the service role, AWS Batch assumes that your ARN doesn't use theservice-rolepath prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.

@Stability(value=Stable) @Nullable public String getState()
If the state is ENABLED , then the compute environment accepts jobs from a queue and can scale out automatically based on queues.
If the state is ENABLED , then the AWS Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.
If the state is DISABLED , then the AWS Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.
