Properties

circuitBreakeroptionalDeploymentCircuitBreakercircuit_breakeroptionalDeploymentCircuitBreakercircuitBreakeroptionalDeploymentCircuitBreakerCircuitBreakeroptionalDeploymentCircuitBreakerCircuitBreakeroptionalDeploymentCircuitBreaker= disabled#

Whether to enable the deployment circuit breaker.

If this property is defined, circuit breaker will be implicitly enabled.

clusteroptionalIClusterclusteroptionalIClusterclusteroptionalIClusterClusteroptionalIClusterClusteroptionalICluster#

The name of the cluster that hosts the service.

Default: create a new cluster; if both cluster and vpc are omitted, a new VPC will be created for you.

If a cluster is specified, the vpc construct should be omitted. Alternatively, you can omit both cluster and vpc.

cpuoptionalnumbercpuoptionalint | floatcpuoptionalNumberCpuoptionaldoubleCpuoptional*float64= 256#

The number of cpu units used by the task.

notes

Valid values, which determines your range of valid values for the memory parameter:

256 (.25 vCPU) - Available memory values: 0.5GB, 1GB, 2GB

512 (.5 vCPU) - Available memory values: 1GB, 2GB, 3GB, 4GB

1024 (1 vCPU) - Available memory values: 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB

2048 (2 vCPU) - Available memory values: Between 4GB and 16GB in 1GB increments

4096 (4 vCPU) - Available memory values: Between 8GB and 30GB in 1GB increments

8192 (8 vCPU) - Available memory values: Between 16GB and 60GB in 4GB increments

16384 (16 vCPU) - Available memory values: Between 32GB and 120GB in 8GB increments

This default is set in the underlying FargateTaskDefinition construct.

desiredTaskCountoptionalnumberdesired_task_countoptionalint | floatdesiredTaskCountoptionalNumberDesiredTaskCountoptionaldoubleDesiredTaskCountoptional*float64= 1#

The desired number of instantiations of the task definition to keep running on the service.

enabledoptionalbooleanenabledoptionalboolenabledoptionalBooleanEnabledoptionalboolEnabledoptional*bool= true#

Indicates whether the rule is enabled.

ephemeralStorageGiBoptionalnumberephemeral_storage_gi_boptionalint | floatephemeralStorageGiBoptionalNumberEphemeralStorageGiBoptionaldoubleEphemeralStorageGiBoptional*float64#

The amount (in GiB) of ephemeral storage to be allocated to the task.

Default: Undefined, in which case, the task will receive 20GiB ephemeral storage.

The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.

Only supported in Fargate platform version 1.4.0 or later.

memoryLimitMiBoptionalnumbermemory_limit_mi_boptionalint | floatmemoryLimitMiBoptionalNumberMemoryLimitMiBoptionaldoubleMemoryLimitMiBoptional*float64= 512#

The amount (in MiB) of memory used by the task.

notes

This field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter:

512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25 vCPU)

1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values: 512 (.5 vCPU)

2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)

Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available cpu values: 2048 (2 vCPU)

Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available cpu values: 4096 (4 vCPU)

Between 16384 (16 GB) and 61440 (60 GB) in increments of 4096 (4 GB) - Available cpu values: 8192 (8 vCPU)

Between 32768 (32 GB) and 122880 (120 GB) in increments of 8192 (8 GB) - Available cpu values: 16384 (16 vCPU)

This default is set in the underlying FargateTaskDefinition construct.

The platform version on which to run your service.

notes

If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide.

Default: Tags will not be propagated

If no value is specified, the tags are not propagated.

ruleNameoptionalstringrule_nameoptionalstrruleNameoptionalStringRuleNameoptionalstringRuleNameoptional*string#
