迭代AWS json響應python

Question

嘗試迭代通過AWS json輸出，並使用以下代碼檢查ECR中是否存在特定版本。但我總是得到「圖像不存在於ECR！」即使圖像標籤存在。

client = boto3.client('ecr') 
response = client.list_images(registryId='my_account_number', repositoryName='my_app') 

for i in response['imageIds']: 
    if i['imageTag'] != version: 
     print(response) 
     print('Image does not exist in ECR!') 
     quit() 
    else: 
     pass 

Answer 1

更改您的代碼運行，直到它找到您所期待的版本：如果沒有找到正確的版本，'Image does not exist in ECR!'將打印

client = boto3.client('ecr') 
response = client.list_images(registryId='my_account_number', repositoryName='my_app') 

for i in response['imageIds']: 
    if i['imageTag'] == version: 
     print('Found matching version!') 
     print(i) 
     break 
else: 
    print('Image does not exist in ECR!')
