通常我将以下图像用于 .net core 3.1 并且它工作正常。

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build

我出于实验原因启动了一个新的 .net 5 项目并创建dockerfile了以下内容

FROM mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim AS base 
FROM mcr.microsoft.com/dotnet/core/sdk:5.0-buster AS build

并有以下问题：

 => ERROR [internal] load metadata for mcr.microsoft.com/dotnet/core/sdk:5.0-buster                           0.2s
 => ERROR [internal] load metadata for mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim                   0.2s

 => => resolve mcr.microsoft.com/dotnet/core/sdk:5.0-buster                                                   0.0s

 => ERROR [base 1/2] FROM mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim                                0.0s
 => => resolve mcr.microsoft.com/dotnet/core/aspnet:5.0-buster-slim

我的项目中有几个 Dockerfile。一种是用于构建basic图像，其中包含一些业务级别的抽象。其他人正在根据basic图像构建服务。

所以在我的服务的 Dockerfiles 中，我有类似的东西

FROM my-project/base
# Adding some custom logic around basic stuff

我使用 GitHub Actions 作为我的 CI/CD 工具。起初我有一个步骤将 docker 安装到我的工人中，然后运行如下：

- name: Build base image
  working-directory: business
  run: docker build -t my-project/base .

- name: Build and push service
  working-directory: service
  run: |
    docker build -t my-ecr-repo/service .
    docker push my-ecr-repo/service

但是后来我找到了 docker/build-push-action 并决定在我的管道中使用它：

- name: Build business-layer container
  uses: docker/build-push-action@v2
  with:
    load: true
    tags: my-project/base
    context: business
    file: business/Dockerfile

- name: Build …
