AWS Fargate可以在以下任务状态中发生中断:
以下是一个使用AWS SDK for Python(Boto3)的示例代码,演示如何捕获和处理任务中断的情况:
import boto3
def handle_interrupted_tasks(cluster_name, region):
client = boto3.client('ecs', region_name=region)
response = client.list_tasks(
cluster=cluster_name,
desiredStatus='STOPPED', # 获取已停止的任务
maxResults=100 # 最多返回100个任务
)
task_arns = response['taskArns']
while 'nextToken' in response: # 如果有更多的任务需要获取,继续循环获取
response = client.list_tasks(
cluster=cluster_name,
desiredStatus='STOPPED',
maxResults=100,
nextToken=response['nextToken']
)
task_arns.extend(response['taskArns'])
for task_arn in task_arns:
response = client.describe_tasks(
cluster=cluster_name,
tasks=[task_arn]
)
task = response['tasks'][0]
if 'stoppedReason' in task: # 如果任务有停止原因,说明发生了中断
task_id = task_arn.split('/')[2] # 提取任务ID
stopped_reason = task['stoppedReason']
print(f"Task {task_id} stopped due to {stopped_reason}")
# 使用示例
cluster_name = 'my-cluster'
region = 'us-west-2'
handle_interrupted_tasks(cluster_name, region)
该示例代码使用boto3
库连接到AWS ECS(Elastic Container Service)并列出了停止的任务。然后,它遍历每个任务并检查是否有停止原因。如果有停止原因,它将打印出任务ID和停止原因。
请注意,要运行此代码,您需要安装boto3
库,并且必须具有适当的AWS凭证和权限来访问ECS服务。
