哪种类型的管道适合我？

创建并运行一个脚本，帮助您评估将 V1 类型管道转到 V2 类型管道的成本

1. 下载并安装 python。

2. 打开终端窗口。运行以下命令创建一个名为 PipelineCostAnalyzer.py 的新 python 脚本。

   vi PipelineCostAnalyzer.py

3. 将以下代码复制并粘贴到 PipelineCostAnalyzer.py 脚本中。

   
   import boto3
   import sys
   import math
   from datetime import datetime, timedelta, timezone
   
   if len(sys.argv) < 3:
       raise Exception("Please provide region name and pipeline name as arguments. Example usage: python PipelineCostAnalyzer.py us-east-1 MyPipeline")
   session = boto3.Session(profile_name='default', region_name=sys.argv[1])
   pipeline = sys.argv[2]
   codepipeline = session.client('codepipeline')
   
   def analyze_cost_in_v2(pipeline_name):
       if codepipeline.get_pipeline(name=pipeline)['pipeline']['pipelineType'] == 'V2':
           raise Exception("Provided pipeline is already of type V2.")
       total_action_executions = 0
       total_blling_action_executions = 0
       total_action_execution_minutes = 0
       cost = 0.0
       hasNextToken = True
       nextToken = ""
   
       while hasNextToken:
           if nextToken=="":
               response = codepipeline.list_action_executions(pipelineName=pipeline_name)
           else:
               response = codepipeline.list_action_executions(pipelineName=pipeline_name, nextToken=nextToken)
           if 'nextToken' in response:
               nextToken = response['nextToken']
           else:
               hasNextToken= False
           for action_execution in response['actionExecutionDetails']:
               start_time = action_execution['startTime']
               end_time = action_execution['lastUpdateTime']
               if (start_time < (datetime.now(timezone.utc) - timedelta(days=30))):
                   hasNextToken= False
                   continue
               total_action_executions += 1
               if (action_execution['status'] in ['Succeeded', 'Failed', 'Stopped']):
                   action_owner = action_execution['input']['actionTypeId']['owner']
                   action_category = action_execution['input']['actionTypeId']['category']
                   if (action_owner == 'Custom' or (action_owner == 'AWS' and action_category == 'Approval')):
                       continue
                   
                   total_blling_action_executions += 1
                   action_execution_minutes = (end_time - start_time).total_seconds()/60
                   action_execution_cost = math.ceil(action_execution_minutes) * 0.002
                   total_action_execution_minutes += action_execution_minutes
                   cost = round(cost + action_execution_cost, 2)
   
       print ("{:<40}".format('Activity in last 30 days:'))
       print ("| {:<40} | {:<10}".format('___________________________________', '__________________'))
       print ("| {:<40} | {:<10}".format('Total action executions:', total_action_executions))
       print ("| {:<40} | {:<10}".format('Total billing action executions:', total_blling_action_executions))
       print ("| {:<40} | {:<10}".format('Total billing action execution minutes:', round(total_action_execution_minutes, 2)))
       print ("| {:<40} | {:<10}".format('Cost of moving to V2 in $:', cost - 1))
   
   analyze_cost_in_v2(pipeline)

4. 在终端或命令提示符处，将目录更改为创建分析器脚本的目录。

   在该目录中运行以下命令，其中 region 是您创建要分析的 V1 管道 Amazon Web Services 区域 的位置。您还可以通过提供特定管道的名称，选择性地对其进行评估：

   python3 PipelineCostAnalyzer.py region --pipelineName

   例如，运行以下命令来运行名为 PipelineCostAnalyzer.py 的 python 脚本。在此示例中，区域为 us-west-2。

   python3 PipelineCostAnalyzer.py us-west-2

   注意

   该脚本将分析指定 Amazon Web Services 区域 内的所有 V1 管道，除非您指定了特定的管道名称。

5. 在脚本的以下输出示例中，我们可以看到操作执行列表、符合计费条件的操作执行列表、这些操作执行的总运行时间，以及在 V2 管道中执行这些操作的估计成本。

   Activity in last 30 days: 
    | ___________________________________      | __________________
    | Total action executions:                 | 9         
    | Total billing action executions:         | 9         
    | Total billing action execution minutes:  | 5.59      
    | Cost of moving to V2 in $:               | -0.76 

   在此示例中，最后一行的负值表示改用 V2 类型管道可能节省的估计金额。

   注意
