要加快ECS扩展的高分辨率度量标准,可以使用AWS服务如CloudWatch和ECS自动缩放来监控和自动扩展ECS集群。以下是一个示例解决方案,包含代码示例:
import boto3
def create_cloudwatch_metric():
cloudwatch = boto3.client('cloudwatch')
response = cloudwatch.put_metric_data(
Namespace='ECS/Cluster',
MetricData=[
{
'MetricName': 'CPUUtilization',
'Dimensions': [
{
'Name': 'ClusterName',
'Value': 'your-cluster-name'
},
],
'Unit': 'Percent',
'Value': 80.0
},
{
'MetricName': 'MemoryUtilization',
'Dimensions': [
{
'Name': 'ClusterName',
'Value': 'your-cluster-name'
},
],
'Unit': 'Percent',
'Value': 60.0
},
]
)
create_cloudwatch_metric()
import boto3
def create_ecs_auto_scaling():
ecs = boto3.client('ecs')
response = ecs.put_scaling_policy(
serviceNamespace='ecs',
resourceId='your-cluster-name',
scalableDimension='ecs:service:DesiredCount',
policyName='your-policy-name',
policyType='TargetTrackingScaling',
targetTrackingScalingPolicyConfiguration={
'targetValue': 70.0,
'predefinedMetricSpecification': {
'predefinedMetricType': 'ECSServiceAverageCPUUtilization'
},
'scaleInCooldown': 60,
'scaleOutCooldown': 60
}
)
create_ecs_auto_scaling()
import boto3
def configure_ecs_service():
ecs = boto3.client('ecs')
response = ecs.update_service(
cluster='your-cluster-name',
service='your-service-name',
desiredCount=10,
deploymentConfiguration={
'maximumPercent': 200,
'minimumHealthyPercent': 50
},
deploymentController={
'type': 'ECS'
},
networkConfiguration={
'awsvpcConfiguration': {
'subnets': [
'subnet-12345678',
'subnet-87654321'
],
'securityGroups': [
'sg-12345678'
],
'assignPublicIp': 'DISABLED'
}
},
healthCheckGracePeriodSeconds=60,
enableExecuteCommand=True,
capacityProviderStrategy=[
{
'capacityProvider': 'FARGATE',
'weight': 1,
'base': 1
},
],
platformVersion='LATEST',
forceNewDeployment=True
)
configure_ecs_service()
请注意,以上代码示例仅供参考,你需要根据你的具体需求进行调整和扩展。此外,你需要正确配置AWS凭证和权限来访问相关服务。
