I am new to docker and so my question could be very naive/stupid. The application that we use presently need to be compiled in different platform to make it work in desired platform i.e Linux and Window mainly. So we need to compile source code(C/C++) in different platform and give different executable to customer as per their OS . My question is 1. Is it possible with docker that i have one executable which work in all platform ? i.e i compile my source code in one platform e.g in Linux and ship executable with docker to run in Window platform
Thanks in advance

You can run both Linux and Windows programs and executables in Docker containers. The Docker platform runs natively on Linux (on x86-64, ARM and many other CPU architectures) and on Windows (x86-64). Docker Inc. builds products that let you build and run containers on Linux, Windows and macOS.
In order to build multi-platform container images, we will use the docker buildx command. Buildx is a Docker component that enables many powerful build features with a familiar Docker user experience. All builds executed via buildx run with Moby Buildkit builder engine.
By default, the Docker images we create run on the linux/amd64 platform. This works for the majority of development machines and cloud providers but leaves users of other platforms out in the cold.
You can run any application in Docker as long as it can be installed and executed unattended, and the base operating system supports the app. Windows Server Core runs in Docker which means you can run pretty much any server or console application in Docker.
You still need to compile source code on different platforms. The point of the docker is to automate building and testing the code on every platform, so that you can just work on the code, and let it build and test on every platform.
You do have to set up the dockers and test scripts and get the code working cross-platform in the first place. But after that is done, you can basically not worry about any other platform unless you actually break it.
