AWS Codebuild "Unknown runtime version named '3.1' of dotnet. This build image has the following versions: 2.2"

Im using codepipeline line to build and deploy - pulling from github and deploying to fargate containers - upon bulding the dotnet application in codebuild I come across this error. Pretty stumped. Does anyone have any ideas why it thinks my app is dotnet 2.2?

This is a brand new pipeline

My dockerfile points to 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"]

My buildspec points to 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

and my dotnet core app is definitely 3.1

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

Based on the comments.

The issue was caused by using old runtime image version Amazon Linux 2 x86_64 standard:1.0 which does not support dotnet 3.1. As listed in the AWS docs only the following versions support dotnet 3.1:

  • Amazon Linux 2 x86_64 standard:3.0

  • Amazon Linux 2 AArch64 standard:2.0

  • Ubuntu standard:4.0

  • Ubuntu standard:5.0

Thus, the solution was to upgrade the image version to Amazon Linux 2 x86_64 standard:3.0.

Moving to Amazon Linux 2 x86_64 standard:3.0 from Amazon Linux 2 x86_64 standard:1.0 fixed this!
