AWS Codebuild "Unknown runtime version named '3.1' of dotnet. This build image has the following v

Question

我使用代码管线来构建和部署-从github提取并部署到fargate容器-在代码构建中构建dotnet应用程序时，我遇到了这个错误。很为难。有人知道为什么它认为我的应用程序是dotnet 2.2吗？

这是一个全新的管道

我的dockerfile指向3.1

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build-env
WORKDIR /app
# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore
# Copy everything else and build
COPY . ./
RUN dotnet publish -c Release -o out
# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet",  "user-bff.dll"]

我的构建规范指向3.1

version: 0.2
phases:
install:
runtime-versions:
dotnet: 3.1
pre_build:
commands:
- cd code/
- echo Logging in to Amazon ECR
- $(aws ecr get-login --region $AWS_DEFAULT_REGION --no-include-email)
- IMAGE_URI="${REPOSITORY_URI}:latest"
build:
commands:
- echo Build started on `date`
- echo Building the Docker image...
- docker build --tag "$IMAGE_URI"
- docker tag $REPOSITORY_URI:latest $REPOSITORY_URI:latest
post_build:
commands:
- echo Build completed on `date`
- echo Push the latest Docker Image...
- docker push "$IMAGE_URI"
- printf '[{"name":"App","imageUri":"%s"}]' "$IMAGE_URI" > images.json
artifacts:
files: images.json

我的dotnet核心应用程序肯定是3.1

Answer 1

基于注释。

该问题是由使用旧的运行时映像版本Amazon Linux 2 x86_64 standard:1.0引起的，不支持dotnet 3.1。如AWS文档中所列，只有以下版本支持dotnet 3.1:

• 亚马逊Linux 2 x86_64标准：3.0

• 亚马逊Linux 2 AArch64标准：2.0

• Ubuntu标准：4.0

• Ubuntu标准：5.0

因此，解决方案是将映像版本升级到Amazon Linux 2 x86_64 standard:3.0。

Answer 2

从Amazon Linux 2 x86_64标准：1.0迁移到Amazon Linux 2 x86_64标准：3.0解决了这个问题！
