Using Docker containers as localhost on Mac/Windows. Tip submitted by @Akuka. Difference between Docker on Linux and Docker on Mac/Windows environments. Based on your OS, your DOCKERHOST is different. On Linux, it will simply be your localhost. For Mac/Windows, you should obtain the appropriate IP using the following command. If you ran the docker pull ros command, you will have a ROS 2 installation (dashing, foxy, etc.) try: ros2 topic list. If you pulled a ROS1 Docker container tag (noetic, kinetic, etc.) try: roscore. Stopping ROS containers. To stop containers, we merely need to stop the original processes run by docker run command.

System requirements

Your Mac must meet the following requirements to successfully install Docker Desktop:

  • macOS must be version 10.14 or newer. That is, Mojave, Catalina, or Big Sur. We recommend upgrading to the latest version of macOS.

    If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.

    Note

    Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. As new major versions of macOS are made generally available, Docker stops supporting the oldest version and supports the newest version of macOS (in addition to the previous two releases). Docker Desktop currently supports macOS Mojave, macOS Catalina, and macOS Big Sur.

  • 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.

What’s included in the installer

Automatic updates
