How to Install Docker on macOS

Posted on by

Docker is a powerful tool for developers, enabling you to create, deploy, and manage containerized applications. Installing Docker on macOS is straightforward, even for beginners, and this guide will walk you through the entire process step by step.

Whether you’re new to Docker or simply need a clear guide, this article covers everything you need to know to set up Docker on macOS. Let’s dive in!

What You’ll Need

Before starting, make sure you have:

  • A Mac running macOS 10.13 or later.
  • Administrator privileges to install applications.
  • A stable internet connection.

Step 1: Download Docker for macOS

  1. Visit the official Docker website: Docker Desktop for macOS.
  2. Click the “Download for Mac” button to download the installer.
  3. Wait for the download to complete (the file is usually named Docker.dmg).

Step 2: Install Docker Desktop

  1. Open the downloaded Docker.dmg file.
  2. Drag the Docker icon into the Applications folder.
  3. Open the Applications folder and double-click the Docker app to launch it.
  4. You may see a prompt asking for your macOS password. Enter it to grant permissions.

Step 3: Start Docker

  1. Once installed, click the Docker icon in the menu bar or search for Docker in Spotlight.
  2. On first launch, Docker will prompt you to log in with a Docker account.
    • If you don’t have an account, you can create one for free at Docker Hub.
  3. Once logged in, Docker Desktop will initialize and be ready to use.

Step 4: Verify the Installation

To confirm that Docker is installed and working correctly, open the Terminal and run the following command:

docker --version

You should see the installed version of Docker, such as:

Docker version 20.10.8, build 3967b7d

Step 5: Test Docker with a Sample Container

Run a simple test to ensure Docker is working:

docker run hello-world

This command pulls a sample image from Docker Hub and runs it. You should see a success message like:

Hello from Docker! This message shows that your installation appears to be working correctly.

Managing Docker

Starting and Stopping Docker

To start Docker, click the Docker icon in the menu bar and select Start Docker.
To stop Docker, click the icon and select Quit Docker Desktop.

Docker Preferences

Access preferences by clicking the Docker icon in the menu bar and selecting Preferences. Here, you can:

  • Allocate resources like CPU and RAM.
  • Configure Docker’s behavior at startup.
  • Set up proxies and network preferences.

Tips for Using Docker on macOS

  • Update Docker Regularly: Keep Docker up-to-date for the latest features and security patches.
  • Use Docker Hub: Search for pre-built images on Docker Hub to save time.
  • Learn Basic Commands: Familiarize yourself with essential Docker commands like docker run, docker ps, and docker stop.
