当docker运行时，会发生错误。 “ValueError：无法configuration处理程序”守望台“：您必须指定一个区域。”
首先，我使用服务器环境
- sever：django + nginx + uwsgi
- 云：docker+ AWS ECS
- 日志logging：AWS CloudWatch日志服务+了望塔第三方应用程序
如果我使用python manage.py runserver在本地运行服务器，则日志将存储在CloudWatch日志中。 但是，如果使用docker run --rm -it -p 8080: 80 image_name和docker run --rm -it -p 8080: 80 image_name命令来构build我的项目，则会发生以下错误。

该错误消息指出了该地区的问题，我不知道如何解决这个问题。 django日志logging设置如下所示。
LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s' }, 'simple': { 'format': '%(levelname)s %(message)s' }, }, 'handlers': { 'watchtower': { 'level': 'DEBUG', 'class': 'watchtower.CloudWatchLogHandler', 'formatter': 'verbose', }, 'console': { 'level': 'INFO', 'class': 'logging.StreamHandler', }, }, 'loggers': { 'django': { 'handlers': ['watchtower', 'console'], 'level': 'INFO', 'propagate': True, }, 'django.user': { 'handlers': ['watchtower'], 'level': DJANGO_LOG_LEVEL, 'propagate': False, }, 'django.partner': { 'handlers': ['watchtower'], 'level': DJANGO_LOG_LEVEL, 'propagate': False, } } }
哪里有问题？
您需要在您的容器内提供aws凭据。 你可以用一个音量来安装它们：
docker run -v $HOME/.aws:/root/.aws --rm -it -p 8080: 80 image_name
您的凭证应该在本地$HOME/.aws ，然后它们被挂载到运行您的应用程序的用户的主目录（如果用户是其他用户，则将/ root更改为另一个目录）
AWS区域未在您的容器中configuration，可能也不是证书。 看看文档或这里 。
上一节中configuration的configuration文件由CLI生成的文件如下所示：
〜/ .aws /凭证
[默认] aws_access_key_id = AKIAIOSFODNN7EXAMPLE aws_secret_access_key = wJalrXUtnFEMI / K7MDENG / bPxRfiCYEXAMPLEKEY
〜/ .aws /configuration
[default] region = us-west-2 output = json
支持以下设置。
aws_access_key_id – AWS访问密钥。
aws_secret_access_key – AWS密钥。
aws_session_token – AWS会话令牌。 会话令牌只有在使用临时安全证书时才是必需的。
区域 – AWS地区。
输出 – 输出格式（json，文本或表格）
