My service uses confluent Kafka driver. I need to run it in Docker. Is there any working example of how to do it? Build image and base container image. And a Dockerfile for it.

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.
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

I am actually new to docker. I have taken basic tutorials on docker and know the commands to docker regarding images, containers.
Now, All my applications servers like running on tomcat9 or nginx and also services like redis , scylla db , activemq are running on the ubuntu servers and installation,everything I am doing it manually.
I am confused like to how to start implementing the docker in my company.
Like for the commercial use, what are the prerequisites, is docker hub account neccessary or else can we use directly like docker pull image_name?
I have searched in many blogs, but could not find the way of implementation.
Install docker on your computer/server first.
Use you cmd/bash/terminal to interact with docker. Just to make sure Docker is installed on you computer by typing on cmd docker ps
If you are using Docker Desktop, you can use Docker desktop to check as well.
Search on hub.docker the image you need. Follow it's instruction, make a cmd docker pull <image> to pull their image first
Use docker run to run you image, if you image need to use a port, make sure that port isn't used by another process.
I need to know what software is required for a machine to run a docker image. E.g., if I want to deploy and run a docker container on a machine X. What is minimum required software to be installed (e.g., docker daemon is sufficient or more is required?)
In my understanding, Machine X needs to be able to connect to Docker registry and there should be runtime environment for docker image to run. But I could not find anywhere minimum requirements to run a docker container on a machine.
I am NOT interested in system HARDWARE requirements.
Edit [24-Nov-2020]: I am looking for windows container deployment
If all you want to run is Docker containers, then just the Docker engine and its supporting packages which can be found in the 'installation' section in the Docker documentation will suffice:

I am new to Docker Swarm. I am wondering if is it possible to add my own build image to the docker service create command?
For example, I have created an image called testing and I run the following cmd "docker service create [OPTIONS] testing".
Thank you and sry for my broken English.
Yes, it is possible. See this documentation here for the docker service create command.
But the image you want to use must be accessible from the Docker swarm. The standard approach here is to upload the image to the Docker Trusted Registry that should be running alongside the Docker swarm, or have the image uploaded to another registry available to the Swarm. This of course only matters when you are working with a production deployment of Docker swarm with multiple nodes and so on. A local swarm on your own machine can use the same images you can use with docker run.
Is windows based image for "couchbase" available to install with docker? or any way around so that couchbase can be installed with docker in windows container.
The images are based always on Linux. You know an image is based on other image recursively till reach a base image like ubuntu, debian or whatever. Anyway, it is suppossed they are not related to the host O.S. They can be run on a Docker using a Windows host, Linux host or OSX host in the same way. On Windows or OSX you can install Docker to run container based on Linux images, there is no problem about that.
Depending of the use of the container, if it needs some hardware to be useful (like wireless cards or something like that), then the host is important because there are drivers and kernel directly involved. But usually, any image can be used to run containers independently of the Docker host.
As of today (2017-10-02), I don't think there is an official Couchbase Docker image for Windows container. Their Dockerfile shows that their images are built off of Ubuntu.
You can try setting everything up manually by following the steps below. (Note that installing via Chocolatey is just a convenience. You can choose another method.)
Get Windows Server Core image.
host> docker pull microsoft/windowsservercore
Start the container in interactive mode
host> docker run -it --name couchbase-on-windows microsoft/windowsservercore
Switch to PowerShell
container-cmd> PowerShell
Install Chocolatey
container-ps> Set-ExecutionPolicy Bypass; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
Install Couchbase. (The version on chocolatey might be a bit behind the latest.)
container-ps> choco install couchbase-server-community
If all this works to your liking, then you can create a Dockerfile to make your own Docker image. You can see what this person did to create an image for Redis on Windows. Here's his Dockerfile.
