Steps to Install Docker on Mac
Step 1: Verify System Requirements
Before you start installing Docker on your Mac, you need to ensure that your machine meets the system requirements. Your Mac must be running macOS Sierra 10.12 or later. To check your macOS version, click the Apple icon on the top left corner of your screen and select About This Mac. You can find your macOS version under the Overview tab.
Step 2: Download Docker Desktop
Next, you need to download the Docker Desktop for Mac installer from the official Docker website. Go to https://www.docker.com/products/docker-desktop and click the Download button to download the installer. Once the download is complete, double-click the installer to begin the installation process.
Step 3: Install Docker Desktop
Double-click the downloaded Docker Desktop for Mac installer to start the installation process. Follow the on-screen instructions, and Docker Desktop will be installed on your Mac. Note that this process may take a few minutes.
Step 4: Launch Docker Desktop
Once Docker Desktop has been installed, launch the application from your Applications folder. Docker Desktop will take a few moments to start up initially.
Step 5: Configure Docker Desktop
After launching Docker Desktop, you need to configure its settings. Click the Docker icon on the top right corner of your screen and select Preferences. Here, you can configure Docker Desktop to use more resources from your machine if needed. Make sure to click the Apply & Restart button after making any changes.
Step 6: Test Docker Desktop
To test if Docker Desktop has been installed and configured correctly, open the Terminal on your Mac and type the following command:
docker run hello-world
If Docker is working correctly, you should see a message that reads “Hello from Docker!”.
Step 7: Update Docker Desktop
It is important to keep Docker Desktop up to date to ensure that it runs smoothly. To update Docker Desktop, click the Docker icon on the top right corner of your screen and select Check for Updates. If any updates are available, click the Install button to install them.
Step 8: Learn Docker Commands
Docker uses specific commands to interact with the platform. As a beginner, you should learn some essential Docker commands. You can find a comprehensive list of commands in the Docker documentation. These commands will help you manage your Docker environment effectively.
Step 9: Find and Pull Docker Images
Docker containers are made up of images that contain the application, its dependencies, and the required libraries. You can find Docker images on the Docker Hub or other public registry. To pull an image from the registry, open the Terminal and type the following command:
docker pull IMAGE_NAME
Replace IMAGE_NAME with the name of the image you want to pull.
Step 10: Create Docker Containers
Once you have pulled an image, you can create a Docker container. A container is an instance of an image. To create a container, open the Terminal and type the following command:
docker run -it IMAGE_NAME /bin/bash
Replace IMAGE_NAME with the name of the image you want to use. This will create a container and open a shell inside it.
Step 11: Manage Docker Volumes
Docker volumes are used to share data between container and host systems. You can create a volume by using the following command:
docker volume create VOLUME_NAME
Replace VOLUME_NAME with the name of the volume you want to create.
Step 12: Clean Up Unused Docker Resources
It is important to clean up any unused Docker resources to save space on your machine. To remove a Docker container, image, or volume, use the following commands:
docker rm CONTAINER_ID
docker rmi IMAGE_ID
docker volume rm VOLUME_NAME
