Run Macos On Docker

Run Mac in a Docker container! Disk # Partition that disk and subtract 1GB and press Apply # Click Reinstall macOS Troubleshooting. Alternative run. Configure docker-machine on macOS. To start Docker Machine via Homebrew, run: brew services start docker-machine To create a default machine (if you don't have one, see: docker-machine ls): docker-machine create -driver virtualbox default Then set-up the environment for the Docker client: eval '$(docker-machine env default)'. And obviously there haven't been easy solutions to run SQL Server natively on Mac OS, which requires me to run it on Windows hosted on Parallels Desktop VM, which in turn makes me sacrifice some host OS resources. As I mentioned, I take it in favor of having some other benefits of working on Mac OS.:) Why Docker?

If you are trying to run Mac OS as the base system in a Docker container, unfortunately there is no way to do it. Docker container need to use the host machine's Linux Kernel, since Mac OS family is Unix-based operating system, currently Docker cannot simulate a Mac OS in Docker container. Here is a link to explain how container works. Step 1: Create a container named dind-test with docker:dind image. Docker run -privileged -d -name dind-test docker:dind. Step 2: Log in to the container using exec. Docker exec -it dind-test /bin/sh. Now, perform steps 2 to 4 from the previous method and validate docker command-line instructions and image build.

Docker Desktop for Mac provides several networking features to make iteasier to use.

Features

VPN Passthrough

Docker Desktop for Mac’s networking can work when attached to a VPN. To do this,Docker Desktop for Mac intercepts traffic from the containers and injects it intoMac as if it originated from the Docker application.

Port Mapping

When you run a container with the -p argument, for example:

Docker Desktop for Mac makes whatever is running on port 80 in the container (inthis case, nginx) available on port 80 of localhost. In this example, thehost and container ports are the same. What if you need to specify a differenthost port? If, for example, you already have something running on port 80 ofyour host machine, you can connect the container to a different port:

Now, connections to localhost:8000 are sent to port 80 in the container. Thesyntax for -p is HOST_PORT:CLIENT_PORT.

HTTP/HTTPS Proxy Support

See Proxies.

Known limitations, use cases, and workarounds

Following is a summary of current limitations on the Docker Desktop for Macnetworking stack, along with some ideas for workarounds.

Changing internal IP addresses

The internal IP addresses used by Docker can be changed via the Settings (Windows)or Preferences (Mac). After changing IPs, it is necessary to reset the Kubernetescluster and to leave any active Swarm.

There is no docker0 bridge on macOS

Because of the way networking is implemented in Docker Desktop for Mac, you cannot see adocker0 interface on the host. This interface is actually within the virtualmachine.

I cannot ping my containers

Docker Desktop for Mac can’t route traffic to containers.

Per-container IP addressing is not possible

The docker (Linux) bridge network is not reachable from the macOS host.

Use cases and workarounds

Run Macos On Docker Windows 7

There are two scenarios that the above limitations affect:

I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS namehost.docker.internal which resolves to the internal IP address used by thehost. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

If you have installed Python on your machine, use the following instructions as an example to connect from a container to a service on the host:

Run Macos On Docker Windows

  1. Run the following command to start a simple HTTP server on port 8000.

    python -m http.server 8000

    If you have installed Python 2.x, run python -m SimpleHTTPServer 8000.

  2. Now, run a container, install curl, and try to connect to the host using the following commands:

I want to connect to a container from the Mac

Port forwarding works for localhost; --publish, -p, or -P all work.Ports exposed from Linux are forwarded to the host.

Our current recommendation is to publish a port, or to connect from anothercontainer. This is what you need to do even on Linux if the container is on anoverlay network, not a bridge network, as these are not routed.

For example, to run an nginx webserver:

To clarify the syntax, the following two commands both expose port 80 on thecontainer to port 8000 on the host:

To expose all ports, use the -P flag. For example, the following commandstarts a container (in detached mode) and the -P exposes all ports on thecontainer to random ports on the host.
