Another neat thing that you can do with containers is to pass environment variables to your container. This way, you could pass it something like the base URL for your API. Your development team would then be a
下面是一个示例docker-compose.yml文件: version:'3'services:app:build:.environment:-DB_HOST=localhost-DB_USER=admin-DB_PASSWORD=passwordports:-8000:8000 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 在上述示例中,我们通过environment关键字来设置环境变量。可以在该字段中添加需要的环境变量,并使用-来分隔...

即便应用已经打包,我们仍然有动态配置的需求,比如 aspnet core 程序使用ASPNETCORE_ENVIRONMENT控制异常显示、postgresql 使用 POSTGRES_USER 和 POSTGRES_PASSWORD 传递凭据。由前文可知我们可以将变量存储在额外的 env 文件中,但业务使用的环境变量与 compose 文件混杂在一起并不是很好的实践。

Environment Variables You can use environment variables to configure SQL Server on Linux Containers. ACCEPT_EULA confirms your acceptance of the End-User Licensing Agreement. MSSQL_SA_PASSWORD is the database system administrator (userid = 'sa') password used to connect to SQL Server once the co...
Docker supports the same approach, surfacing config settings as environment variables in containers. You can use environment variables in two ways: in the Dockerfile, specifying values which are baked into the image, which become default values for all containers; when you run a container, specifyi...
