# Docker pull Command [Docker Command Manual](#) * * * The `docker pull` command is used to pull (download) images from a Docker registry (such as Docker Hub) to the local machine. The `docker pull` command allows users to obtain the desired images to run containers locally. ### Syntax docker pull NAME[:TAG|@DIGEST] * **`NAME`**: The image name, which usually includes the registry address (e.g., `docker.io/library/ubuntu`). * **`TAG`** (optional): The image tag, defaulting to `latest`. * **`DIGEST`** (optional): The SHA256 digest of the image. Common options: * **`--all-tags, -a`**: Download all tags for the specified image. * **`--disable-content-trust`**: Skip image signature verification. **1. Pull an image with the default tag (latest)** docker pull ubuntu This pulls the image named `ubuntu` from Docker Hub, with the default tag `latest`. **2. Pull an image with a specific tag** docker pull ubuntu:20.04 This pulls the image named `ubuntu` from Docker Hub, with the tag `20.04`. **3. Pull an image with a specific digest** docker pull ubuntu@sha256:12345abcdef... This pulls the `ubuntu` image with a specific SHA256 digest. **4. Pull an image with all tags** docker pull --all-tags ubuntu This pulls all available tags for the `ubuntu` image. **5. Pull an image from a custom registry** docker pull myregistry.com/myrepo/myimage:mytag This pulls the `myimage` image from the `myrepo` repository in the `myregistry.com` registry, with the tag `mytag`. ### Examples 1. Pull the Ubuntu image: docker pull ubuntu Example output: Using default tag: latest latest: Pulling from library/ubuntu Digest: sha256:12345abcdef...Status: Downloaded newer image for ubuntu:latest docker.io/library/ubuntu:latest 2. Pull a specific tag of the Ubuntu image docker pull ubuntu:20.04 Example output: 20.04: Pulling from library/ubuntu Digest: sha256:67890abcdef...Status: Downloaded newer image for ubuntu:20.04 docker.io/library/ubuntu:20.04 ### Notes * The default tag is `latest`, but it's best to explicitly specify a tag to avoid pulling an unintended version. * Ensure you have enough disk space to store the pulled images. * In production environments, it is recommended to use the image digest to ensure the uniqueness and consistency of the image. The `docker pull` command is a fundamental tool for obtaining Docker images. By specifying the image name, tag, or digest, you can download the required images from a Docker registry. * * Docker Command Manual](#)
