computeEnvironmentArn
Type:
string
The ARN of this compute environment.
computeEnvironmentName
Type:
string
The name of the ComputeEnvironment.
connections
Type:
Connections
The network connections associated with this resource.
enabled
Type:
boolean
Whether or not this ComputeEnvironment can accept jobs from a Queue.
Enabled ComputeEnvironments can accept jobs from a Queue and can scale instances up or down. Disabled ComputeEnvironments cannot accept jobs from a Queue or scale instances up or down.
If you change a ComputeEnvironment from enabled to disabled while it is executing jobs,
Jobs in the STARTED
or RUNNING
states will not
be interrupted. As jobs complete, the ComputeEnvironment will scale instances down to minvCpus
.
To ensure you aren't billed for unused capacity, set minvCpus
to 0
.
env
Type:
Resource
The environment this resource belongs to.
For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.
instanceClasses
Type:
Instance
[]
The instance classes that this Compute Environment can launch.
Which one is chosen depends on the AllocationStrategy
used.
Batch will automatically choose the size.
instanceTypes
Type:
Instance
[]
The instance types that this Compute Environment can launch.
Which one is chosen depends on the AllocationStrategy
used.
maxvCpus
Type:
number
The maximum vCpus this ManagedComputeEnvironment
can scale up to.
Note: if this Compute Environment uses EC2 resources (not Fargate) with either AllocationStrategy.BEST_FIT_PROGRESSIVE
or
AllocationStrategy.SPOT_CAPACITY_OPTIMIZED
, or AllocationStrategy.BEST_FIT
with Spot instances,
The scheduler may exceed this number by at most one of the instances specified in instanceTypes
or instanceClasses
.
node
Type:
Node
The tree node.
securityGroups
Type:
ISecurity
[]
The security groups this Compute Environment will launch instances in.
stack
Type:
Stack
The stack in which this resource is defined.
tags
Type:
Tag
TagManager to set, remove and format tags.
allocationStrategy?
Type:
Allocation
(optional, default: BEST_FIT_PROGRESSIVE
if not using Spot instances,
SPOT_CAPACITY_OPTIMIZED
if using Spot instances.)
The allocation strategy to use if not enough instances of the best fitting instance type can be allocated.
images?
Type:
Ecs
[]
(optional, default: ECS_AL2 compatible AMI ids for non-GPU instances, ECS_AL2_NVIDIA compatible AMI ids for GPU instances)
Configure which AMIs this Compute Environment can launch.
Leave this undefined
to allow Batch to choose the latest AMIs it supports for each instance that it launches.
instanceRole?
Type:
IRole
(optional, default: a role will be created)
The execution Role that instances launched by this Compute Environment will use.
launchTemplate?
Type:
ILaunch
(optional, default: no launch template)
The Launch Template that this Compute Environment will use to provision EC2 Instances.
Note: if securityGroups
is specified on both your
launch template and this Compute Environment, **the
securityGroup
s on the Compute Environment override the
ones on the launch template.
minvCpus?
Type:
number
(optional, default: 0)
The minimum vCPUs that an environment should maintain, even if the compute environment is DISABLED.
placementGroup?
Type:
IPlacement
(optional, default: no placement group)
The EC2 placement group to associate with your compute resources.
If you intend to submit multi-node parallel jobs to this Compute Environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential.

replaceComputeEnvironment?
Type:
boolean
(optional)
Specifies whether this Compute Environment is replaced if an update is made that requires replacing its instances.
To enable more properties to be updated,
set this property to false
. When changing the value of this property to false,
do not change any other properties at the same time.
If other properties are changed at the same time,
and the change needs to be rolled back but it can't,
it's possible for the stack to go into the UPDATE_ROLLBACK_FAILED state.
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.
The properties which require a replacement of the Compute Environment are:
serviceRole?
Type:
IRole
(optional, default: a serviceRole will be created for managed CEs, none for unmanaged CEs)
The role Batch uses to perform actions on your behalf in your account, such as provision instances to run your jobs.
spot?
Type:
boolean
(optional, default: false)
Whether or not to use spot instances.
Spot instances are less expensive EC2 instances that can be reclaimed by EC2 at any time; your job will be given two minutes of notice before reclamation.
spotBidPercentage?
Type:
number
(optional, default: 100%)
The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched.
For example, if your maximum percentage is 20%, the Spot price must be less than 20% of the current On-Demand price for that Instance. You always pay the lowest market price and never more than your maximum percentage. For most use cases, Batch recommends leaving this field empty.
spotFleetRole?
Type:
IRole
(optional, default: a new Role will be created)
The service-linked role that Spot Fleet needs to launch instances on your behalf.
See also: https://docs.aws.amazon.com/batch/latest/userguide/spot_fleet_IAM_role.html
terminateOnUpdate?
Type:
boolean
(optional, default: false)
Whether or not any running jobs will be immediately terminated when an infrastructure update occurs.
If this is enabled, any terminated jobs may be retried, depending on the job's retry policy.
updateTimeout?
Type:
Duration
(optional, default: 30 minutes)
Only meaningful if terminateOnUpdate
is false
.
If so,
when an infrastructure update is triggered, any running jobs
will be allowed to run until updateTimeout
has expired.
updateToLatestImageVersion?
Type:
boolean
(optional, default: false)
Whether or not the AMI is updated to the latest one supported by Batch when an infrastructure update occurs.
If you specify a specific AMI, this property will be ignored.
Note: the CDK will never set this value by default, false
will set by CFN.
This is to avoid a deployment failure that occurs when this value is set.

useOptimalInstanceClasses?
Type:
boolean
(optional, default: true)
Whether or not to use batch's optimal instance type.
The optimal instance type is equivalent to adding the C4, M4, and R4 instance classes. You can specify other instance classes (of the same architecture) in addition to the optimal instance classes.
vpcSubnets?
Type:
Subnet
(optional)
The VPC Subnets this Compute Environment will launch instances in.

applyRemovalPolicy(policy)
public applyRemovalPolicy(policy: RemovalPolicy): void

Removal
Policy
Apply the given removal policy to this resource.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.
The resource can be deleted (RemovalPolicy.DESTROY
), or left in your AWS
account for data recovery and cleanup later (RemovalPolicy.RETAIN
).
