Docker Hub Quickstart

Estimated reading time: 2 minutes

Docker Hub is a service provided by Docker for finding and sharing container images with your team. It provides the following major features:

Repositories: Push and pull container images.
Teams & Organizations: Manage access to private repositories of container images.
Official Images: Pull and use high-quality container images provided by Docker.
Publisher Images: Pull and use high-quality container images provided by external vendors. Certified images also include support and guarantee compatibility with Docker Enterprise.
Builds: Automatically build container images from GitHub and Bitbucket and push them to Docker Hub
Webhooks: Trigger actions after a successful push to a repository to integrate Docker Hub with other services.

To create a repo:

Create Repository

You’ve created your first repo. You should see:

Repository Created

We’ll need to download Docker Desktop to build and push a container image to Docker Hub.

Download and install Docker Desktop. If on Linux, download Docker Engine - Community
Open the terminal and sign in to Docker Hub on your computer by running docker login

Start by creating a Dockerfile to specify your application as shown below. (More on Dockerfiles here)

cat > Dockerfile <<EOF
FROM busybox
CMD echo "Hello world! This is my first Docker image."
EOF

Run docker build -t <your_username>/my-first-repo . to build your Docker image
Test your docker image locally by running docker run <your_username>/my-first-repo
Run docker push <your_username>/my-first-repo to push your Docker image to Docker Hub

You should see output similar to:

Terminal

And in Docker Hub, your repository should have a new latest tag available under Tags:

Tag Created
