How do I pull a Docker image in CircleCI?

To pull a Docker image in CircleCI, you can use the docker command in your configuration file.

Can you show me an example of the configuration?

Sure! Here's a simple example:

version: 2.1
jobs:
  build:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run: docker pull your-image-name

What if I need to use a private Docker registry?

You can use the docker login command to authenticate with your private registry before pulling the image.

Is there a way to cache the Docker images?

Yes, you can use the docker layer caching feature in CircleCI to speed up your builds by caching layers.
