解决AWS车队管理与动态扩展的方法包含以下步骤和代码示例:
import boto3
# 创建Auto Scaling组
def create_auto_scaling_group():
client = boto3.client('autoscaling')
response = client.create_auto_scaling_group(
AutoScalingGroupName='fleet-asg',
LaunchConfigurationName='fleet-launch-config',
MinSize=1,
MaxSize=10,
DesiredCapacity=5
)
print(response)
import boto3
# 创建Elastic Load Balancer
def create_elb():
client = boto3.client('elbv2')
response = client.create_load_balancer(
Name='fleet-elb',
Subnets=['subnet-12345678', 'subnet-87654321'],
SecurityGroups=['sg-12345678'],
Type='application',
Scheme='internet-facing'
)
print(response)
import boto3
# 将Auto Scaling组与ELB关联
def attach_load_balancer():
client = boto3.client('autoscaling')
response = client.attach_load_balancer_target_groups(
AutoScalingGroupName='fleet-asg',
TargetGroupARNs=['arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/fleet-tg/abcdef123456']
)
print(response)
import boto3
# 配置自动扩展策略
def configure_scaling_policy():
client = boto3.client('autoscaling')
response = client.put_scaling_policy(
AutoScalingGroupName='fleet-asg',
PolicyName='fleet-scaling-policy',
PolicyType='TargetTrackingScaling',
TargetTrackingConfiguration={
'PredefinedMetricSpecification': {
'PredefinedMetricType': 'ASGAverageCPUUtilization'
},
'TargetValue': 70.0
}
)
print(response)
请注意,上述代码示例中的参数值需要根据你的实际情况进行更改。另外,确保你已正确配置AWS CLI和相关权限,以便运行这些代码。
