docker 注册表日志级别更改

问题描述 投票：0回答：2

我正在尝试在创建注册表容器时更改 docker 注册表的日志级别。

docker run -d -p 5000:5000 --restart=always --name registry -e LOG_LEVEL=debug registry:2

当我运行以下命令查看日志时，它仅提供信息级日志

docker logs registry

time="2023-12-21T20:07:44.13670802Z" level=warning msg="No HTTP secret provided - generated random secret. This may cause problems with uploads if multiple registries are behind a load-balancer. To provide a shared secret, fill in http.secret in the configuration file or set the REGISTRY_HTTP_SECRET environment variable." go.version=go1.20.8 instance.id=607dce47-0f7b-4959-9818-d859fc71a566 service=registry version=2.8.3 
time="2023-12-21T20:07:44.136763361Z" level=info msg="redis not configured" go.version=go1.20.8 instance.id=607dce47-0f7b-4959-9818-d859fc71a566 service=registry version=2.8.3 
time="2023-12-21T20:07:44.136831792Z" level=info msg="using inmemory blob descriptor cache" go.version=go1.20.8 instance.id=607dce47-0f7b-4959-9818-d859fc71a566 service=registry version=2.8.3 
time="2023-12-21T20:07:44.136998129Z" level=info msg="listening on [::]:5000" go.version=go1.20.8 instance.id=607dce47-0f7b-4959-9818-d859fc71a566 service=registry version=2.8.3 
time="2023-12-21T20:07:44.137039251Z" level=info msg="Starting upload purge in 55m0s" go.version=go1.20.8 instance.id=607dce47-0f7b-4959-9818-d859fc71a566 service=registry version=2.8.3

我也尝试过以下命令，但它仍然显示信息级别

 docker run -d -p 5000:5000 --restart=always --name registry -e REGISTRY_LOG_LEVEL=debug registry:2
docker docker-registry

简短回答：您应该能够使用名为 

LOG_LEVEL
的环境变量来设置 
REGISTRY_LOG_LEVEL
:

docker run -d -p 5000:5000 --restart=always --name registry -e REGISTRY_LOG_LEVEL=debug registry:2

长答案：虽然维护者的指导通常是使用配置文件而不是修改环境变量，但文档确实表明应该可以修改默认配置值，而无需通过制作一个非常具体命名的文件来修改默认配置值。与配置键/值对所属层次结构相对应的环境变量：

要覆盖配置选项，请创建一个环境变量 命名为 

REGISTRY_variable
，其中 
variable
是名称 配置选项，
_
（下划线）代表缩进 水平。例如，您可以配置 文件系统存储后端：
rootdirectory


要覆盖此值，请设置一个环境变量，如下所示：


storage:
  filesystem:
    rootdirectory: /var/lib/registry 



此变量将 
REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/somewhere

 值覆盖到 
/var/lib/registry
 目录。


再次参考上面链接的文档页面，您可能希望设置一个名为 
/somewhere
 的环境变量。在您的 
REGISTRY_LOG_LEVEL=debug
 命令的上下文中，它看起来与您之前的非常相似：
docker run

docker run -d -p 5000:5000 --restart=always --name registry -e REGISTRY_LOG_LEVEL=debug registry:2

：
-e REGISTRY_LOG_LEVEL=debug


但是，您似乎没有做任何会生成任何调试日志的事情。请注意，除了信息和警告级别之外，打开调试日志记录还会添加日志，但仍然需要执行一些操作来生成日志：


docker run --rm -p 5001:5000 -e REGISTRY_LOG_LEVEL=debug registry:2



这些日志是通过启动注册表后运行以下命令生成的：


$ docker run --rm -p 5001:5000 -e REGISTRY_LOG_LEVEL=debug registry:2
