Docker Hub Quickstart
The following section contains step-by-step instructions on how to easily get started with Docker Hub.
Step 1: Sign up for a Docker account
Let’s start by creating a Docker ID.
A Docker ID grants you access to Docker Hub repositories and allows you to explore images that are available from the community and verified publishers. You’ll also need a Docker ID to share images on Docker Hub.
Step 2: Create your first repository
To create a repository:
- Sign in to Docker Hub.
- Click Create a Repository on the Docker Hub welcome page.
- Name it <your-username>/my-private-repo.
Set the visibility to Private.
You’ve created your first repository. You should see:
Step 3: Download and install Docker Desktop
You’ll need to download Docker Desktop to build, push, and pull container images.
Download and install Docker Desktop.
Sign in to the Docker Desktop application using the Docker ID you’ve just created.
Step 4: Pull and run a container image from Docker Hub
docker pull hello-worldto pull the image from Docker Hub. You should see output similar to:
$ docker pull hello-world Using default tag: latest latest: Pulling from library/hello-world 2db29710123e: Pull complete Digest: sha256:7d246653d0511db2a6b2e0436cfd0e52ac8c066000264b3ce63331ac66dca625 Status: Downloaded newer image for hello-world:latest docker.io/library/hello-world:latest
docker run hello-worldto run the image locally. You should see output similar to:
$ docker run hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
Step 5: Build and push a container image to Docker Hub from your computer
Start by creating a Dockerfile to specify your application as shown below:
# syntax=docker/dockerfile:1 FROM busybox CMD echo "Hello world! This is my first Docker image."
docker build -t <your_username>/my-private-repo .to build your Docker image.
docker run <your_username>/my-private-repoto test your Docker image locally.
docker push <your_username>/my-private-repoto push your Docker image to Docker Hub. You should see output similar to:
You must be signed in to Docker Hub through Docker Desktop or the command line, and you must also name your images correctly, as per the above steps.
Your repository in Docker Hub should now display a new
