Docker Container With Docker Installed



Estimated reading time: 3 minutes

The Docker CLI has a command called run which will start a container based on a Docker Image. The structure is docker run. By default, Docker will run a command in the foreground. To run in the background, the option -d needs to be specified. Docker run -d redis. By default, Docker will run the latest version available. Now you can even run graphical applications (if they are installed in the container) using X11 forwarding to the SSH client: ssh -X username@IPADDRESS xeyes ## run an X11 demo app in the client Here are some related resources: openssh-server doesn't start in Docker container; How to get bash or ssh into a running container in background mode? The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal. If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub. In case of Docker Container, since the container runs on your host OS, you can save precious boot-up time. This is a clear advantage over Virtual Machine. Consider a situation where I want to install two different versions of Ruby on my system. A sandboxed local environment that replicates the live AWS Lambda environment almost identically – including installed software and libraries, file structure and permissions, environment variables, context objects and behaviors – even the user and running process are the same.

System requirements

Docker image with docker installed

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

The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.

    The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.

    If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.

Installed

Automatic updates

Starting with Docker Desktop 3.0.0, updates to Docker Desktop will be available automatically as delta updates from the previous version.

When an update is available, Docker Desktop automatically downloads it to your machine and displays an icon to indicate the availability of a newer version. All you need to do now is to click Update and restart from the Docker menu. This installs the latest update and restarts Docker Desktop for the changes to take effect.

Uninstall Docker Desktop

To uninstall Docker Desktop from your Mac:

  1. From the Docker menu, select Troubleshoot and then select Uninstall.
  2. Click Uninstall to confirm your selection.

Important

Uninstalling Docker Desktop destroys Docker containers, images, volumes, andother Docker related data local to the machine, and removes the files generatedby the application. Refer to the back up and restore datasection to learn how to preserve important data before uninstalling.
