Installing Docker on Your Mac

1. Download Docker Desktop for Mac:

2. Install Docker Desktop:

- Open the downloaded .dmg file. - Drag the Docker icon to the Applications folder to install it. - Open Docker from your Applications folder. - You may be prompted to enter your email, so follow the on-screen instructions.

3. Verify the Installation:

  • Open a terminal and type the following command to check if Docker is installed correctly:

    docker --version

4. Run a Test Container:

  • To ensure Docker is functioning properly, run a simple container like “Hello World”:

    docker run hello-world

  • This command will download a test image and run it, outputting a message that confirms Docker is installed and working.

  • If you run a Docker command like docker run hello-world for the first time and see a message saying, “Unable to find the image locally”, don’t worry! This just means the image isn’t on your machine yet.

  • Docker will automatically start downloading the image from Docker Hub. Once the image is downloaded, it will run.
