问题及解决
有关Json文件的输入和输出
json.loads函数是将一个字符串(String)输入转换为字典类型(dictionary)输出 json.dumps函数是将一个字典类型(dictionary)输入转换为字符串(String)输出
当出现JSON object must be str, bytes or bytearray, not dict或者dict object has no attribute read的错误时需要检查以上输入类型是否正确。
对于datetime.datetime not JSON serializable的问题也就是日期类型无法进行Json序列化可以使用以下指令解决问题应该是defaultstr这个参数起了作用将日期类型处理为了字符串
json_formatted_str json.dumps(task_definition, indent2, sort_keysTrue, defaultstr)使用Python3及正则表达式查找字符串包含某个子字符串
使用以下办法
exp re.compile(stack_name_to_Search)
stack_name cfn_stack[StackName]
if re.search(exp, stack_name):....以上是查找 stack_name 这个字符串是否包含stack_name_to_Search这个子字符串。
使用Python3 Boto3删除AWS CloudFormation的栈Stacks
def delete_skms_stack(stack_name):cf_client boto3.client(cloudformation)#list all the stacks excepts DELETED_STACKSresponse cf_client.list_stacks(StackStatusFilter[CREATE_IN_PROGRESS,CREATE_FAILED,CREATE_COMPLETE,ROLLBACK_IN_PROGRESS,ROLLBACK_FAILED,ROLLBACK_COMPLETE,DELETE_IN_PROGRESS,DELETE_FAILED,UPDATE_IN_PROGRESS,UPDATE_COMPLETE_CLEANUP_IN_PROGRESS,UPDATE_COMPLETE,UPDATE_FAILED,UPDATE_ROLLBACK_IN_PROGRESS,UPDATE_ROLLBACK_FAILED,UPDATE_ROLLBACK_COMPLETE_CLEANUP_IN_PROGRESS,UPDATE_ROLLBACK_COMPLETE,REVIEW_IN_PROGRESS,IMPORT_IN_PROGRESS,IMPORT_COMPLETE,IMPORT_ROLLBACK_IN_PROGRESS,IMPORT_ROLLBACK_FAILED,IMPORT_ROLLBACK_COMPLETE])#Stack name patternexp re.compile(stack_name)print(--------------------)print(response[StackSummaries])for cfn_stack in response[StackSummaries]:stack_name cfn_stack[StackName]#match re.search(regex_pattern,stack_name)if re.search(exp, stack_name):#Custome conditions can be implemented heretry:response cf_client.delete_stack(StackNamestack_name)stack_delete_status cf_client.describe_stacks(StackNamestack_name)logger.info(Delete stack: json.dumps(response))while stack_delete_status[Stacks][0][StackStatus] DELETE_IN_PROGRESS:time.sleep(10)stack_delete_status cf_client.describe_stacks(StackNamestack_name)logger.info(Delete stack status: stack_delete_status[Stacks][0][StackStatus])if stack_delete_status[Stacks][0][StackStatus] DELETE_FAILED:logger.warning(Delete failed. Retry delete)resources cf_client.delete_stack(StackNamestack_name)return resourceselif stack_delete_status[Stacks][0][StackStatus] DELETE_IN_PROGRESS:continueelse:logger.info(Delete stack complete)except Exception as e:logger.error(e)
以上代码执行效果如下
INFO:__main__:Delete stack status: DELETE_IN_PROGRESS
INFO:__main__:Delete stack status: DELETE_IN_PROGRESS
INFO:__main__:Delete stack status: DELETE_IN_PROGRESS
INFO:__main__:Delete stack status: DELETE_IN_PROGRESS
ERROR:__main__:An error occurred (ValidationError) when calling the DescribeStacks operation: Stack with id ECS-Console-V2-Service-sammperso-johnvpc-svc-John-VPC-Cluster-8c3e39c8 does not exist其中最后一个错误是因为CloudFormation的栈Stacks已经被删除找不到了所以是正常返回。
