If you want to build .Net with AWS CodeBuild Windows Server, or some C# Framework, sometimes you will encounter problems with native compilation that cannot be compiled properly. You should create your own Docker Image.

Instructions Environment: Use a host or virtual machine or a direct EC2 (Windows Sever 2016 with Containers). At least 60GB of space is recommended for t2. Medium or higher. The build image will be better. The following is directly through EC2. After the step is completed, connect to the remote desktop.

• Run command administrator (cmd.exe)
  

• Create a working directory of build image:

  Mkdir C:\\BuildTools   
  Cd C:\\BuildTools   
  

• Create C:\BuildTools\Dockerfile:

  # escape=\`

  FROM microsoft/dotnet-framework:4.7.2-runtime

  SHELL \["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"\]

  }

• Execute the command to build Image

  Docker build -t buildtool:latest -m 3GB .   
  

• After waiting for the run to complete
  You can use the following instructions to enter the container test

  Docker run -it buildtool
  

• After testing OK, you can prepare to upload to AWS ECR

  Aws ecr get-login --region region --no-include-email
  

• Paste the login information once and log in to docker
  After logging in to docker, you can upload the just buildtool to aws ecr

  Docker tag buildtool:latest #ACCOUNT_ID#.dkr.ecr.#REGION#.amazonaws.com/ buildtool:latest
  Docker push #ACCOUNT_ID#.dkr.ecr.#REGION#.amazonaws.com/buildtool:latest
  

• Once the upload is complete, you can find the Image you just uploaded in AWS ECR. The option in CodeBuild will appear.
