Docker 中的 Docker 和适用于 Windows 容器的 AWS CLI

Question

I'm trying to migrate .NET legacy application to AWS ECS/Fargate. I'm following this article that explains how to create a custom Windows Docker image with MSBuild tools used in AWS CodePipeline/CodeBuild project. I also need to be able to install a Docker deamon and AWS CLIV2 into that custom image so that I could execute docker and AWS CLI commands in buildspec.yaml file in CodeBuild. So far I've been able to use this code in my custom image Dockerfile which installs Docker in Docker but the Docker service never gets started even though it understands docker --version command. I was also trying to modify this PowerShell script to install AWS CLI but also stuck with having little to no progress.

I'd appreciate any help in installing Docker in Docker and AWS CLI.

Answer 1

When I had to use docker in docker, I instead used the host docker socket by mounting that in the container.

I had to mount 2 files in linux.

/usr/bin/docker (executable)
/var/run/docker.sock (service socket)

Update - Above would work for linux, for windows, a double slash is required. Below socket would have to be mounted for windows. I couldn't personally test as I don't have windows.

"\\.\pipe\docker_engine:\\.\pipe\docker_engine"

I found a very good GUI tool explained this
