Can I run Windows OS in Docker?
You can’t, because containers are an OS-level construct. So you can’t run Windows in a Docker container on Linux because Windows doesn’t run on Linux. Use virtualization to run multiple operating systems on the same machine. VMware Fusion or Workstation is my recommendation. You can run Linux and Windows 10 side-by-side. , I love Docker.

Your containers are all based on images, most of which you probably pull from DockerHub or some other public repository. But why not create your own custom images?
Can Docker run on Windows and Mac?
Developers who work on Windows can create images for either Linux or Windows Containers. To host containers in development environments and provide additional developer tools, Docker ships Docker Desktop for Windows or for macOS.
Do Docker containers share OS?
Docker containers do not package up the OS. They package up the applications with everything that the application needs to run. The engine is installed on top of the OS running on a host. Containers share the OS kernel allowing a single host to run multiple containers.
Can Docker run cross platform?
Luckily the two techniques can be combined. For example, your Dockerfile can use emulation to install packages from the package manager and use cross-compilation to build your source code. Emulation vs. cross-compilation build with “ — platform=linux/amd64,linux/arm64″ as run on Intel/AMD machine.
Can Docker containers run on Mac?
Docker Desktop currently supports macOS Catalina, macOS Big Sur, and macOS Monterey. At least 4 GB of RAM. VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.
Can containers have different OS?
Yes, they do. Every container is based on an OS image, e.g. Alpine, CentOS or Ubuntu. They just share the host kernel, but run every user-space process in a separate name space specific for that container.
Are Docker containers OS independent?
According to Docker, a container is ” a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it.” And since containers are platform-independent, Docker can run across both Windows- and Linux-based platforms.
Can Docker image run on different OS?
Short answer is yes. Each docker container uses its own file system (has its own mount name space). As long as you don't use any kernel specific features (like insmod of a kernel module in an application running inside a privileged container on Linux), containers themselves are portable.
How many Docker containers can I run per host?
Using this simple calculation, we can estimate that we can run about 1,000 containers on a single host with 10GB of available disk space.
Can Windows Docker run Linux containers?
Docker has been able to run Linux containers on Windows desktop since it was first released in 2016 (before Hyper-V isolation or Linux containers on Windows were available) using a LinuxKit based virtual machine running on Hyper-V.
Can I run Linux Docker containers on Mac?
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.
Can you run Docker on Mac without Docker Desktop?
Docker Desktop installs Docker Engine, which can run only on Linux. So far, we have installed only CLI tools. For images to run, we need an environment. Rancher Desktop replaces Docker Desktop!
Can you use Docker on Mac without Docker Desktop?
The YAML for my Lima VM uses Alpine and installs/configures qus so that you can run multi-arch Docker containers, even on M1 Macs. I've been using this setup for the last two days and it's been smooth sailing.
