docker - 如何在Docker Compose中为容器和图像命名？

Question

我有一个简单的ASP.NET Core Web with SQL Server项目，名为PostOptimizer，由Visual Studio 2017创建并部署到Docker容器。我想给由Docker-compose创建的每个图像和容器命名，因为它会自动给出如下名称:
“dockercompose7669752967822022310_postoptimizer_1” 和“dockercompose7669752967822022310_sql.data_1”

即使在阅读了Docker Compose的Service configuration reference之后，我仍然不知道该怎么做，我希望它能够像 name:“thecontainername” 一样放置构建的子项，但是它不可用。怎么做？

这是我的 docker-compose.yml 文件的内容:

version: '3.4'

services:
  sql.data:
    image: microsoft/mssql-server-linux:2017-latest
    environment:
      - SA_PASSWORD=Sql_Password1
      - ACCEPT_EULA=Y
    ports:
      - "5434:1433"

  postoptimizer:
    image: ${DOCKER_REGISTRY-}postoptimizer
    build:
      context: .
      dockerfile: PostOptimizer/Dockerfile
    depends_on:
      - sql.data

这是Dockerfile之一:

FROM build AS publish
RUN dotnet publish PostOptimizer.csproj -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "PostOptimizer.dll"]

您可以使用子项container_name，它将使用您的给定名称命名容器。

version: '3.4'

services:
  sql.data:
    image: microsoft/mssql-server-linux:2017-latest
    environment:
      - SA_PASSWORD=Sql_Password1
      - ACCEPT_EULA=Y
    ports:
      - "5434:1433"
    container_name: sqldata

  postoptimizer:
    image: ${DOCKER_REGISTRY-}postoptimizer
    build:
      context: .
      dockerfile: PostOptimizer/Dockerfile
    depends_on:
      - sql.data
    container_name: postoptimizer
