This article mainly explains "how to download images from Docker Hub and run them locally". The explanation in this article is simple and clear, easy to learn and understand. Please follow the ideas of Xiaobian and study and learn "how to download images from Docker Hub and run them locally" together!

You can also use the official Docker images that are publicly available. I use many of these mirrors, including my experimental WordPress environment, KDE plasma application, and more. Although we learned last time how to create your own Docker image, you don't have to do this. DockerHub has thousands of images posted for you to use. DockerHub is hardcoded into Docker as the default repository, so when you run docker pull on any image, it will download from DockerHub.

Download images from Docker Hub and run locally

Once Docker is running on your system, you can open the terminal and run:

$ docker images

This command displays all docker images on the current system. Assuming you want to deploy Ubuntu on your local machine, you might:

$ docker pull ubuntu

If an Ubuntu image already exists on your system, this command will automatically update the system to the latest version. So if you want to update an existing image, just run docker pull and it's a breeze. It's like apt-get update, without any confusion or hassle.

You already know how to run mirroring:

$ docker run -it$ docker run -it ubuntu

The command prompt should read as follows:

root@1b3ec4621737:/#

You can now run any Ubuntu command and utility that is included and secure. You can run all your experiments and tests on Ubuntu. Once you're done testing, you can destroy the image and download a new one. There is no overhead in virtual machines.

You can exit the container by running the exit command:

$ exit

Now suppose you want to install Nginx on your system, run search to find the image you need:

$ docker search nginx

As you can see, there are many Nginx mirrors on DockerHub. Why not? Because anyone can publish images, the various images are optimized for different projects, so you can choose the right one. You just need to install the right image for your needs.

Suppose you want to pull Bitnami's Nginx image:

$ docker pull bitnami/nginx

Now run:

$ docker run -it bitnami/nginx How to publish images to Docker Hub?

Before that, we learned how to create a Docker image, which we can easily publish to DockerHub. First, you need to log in to DockerHub, if you don't have an account, create one. Then, you can open the terminal application and log in:

$ docker login --username=

Replace "" with your own Docker Hub username. This is arnieswap:

$ docker login --username=arnieswap

Enter your password and you're logged in. Now run docker images to get the ID of the last image you created.

$ docker images

Now, suppose you want to push an image ng to DockerHub, first we need to tag the image (learn more about tagging):

$ docker tag e7083fd898c7 arnieswap/my_repo:testing

Now push mirror:

$ docker push arnieswap/my_repo

The push points to docker.io/arnieswap/my_repo repository:

12628b20827e: Pushed8600ee70176b: Mounted from library/ubuntu2bbb3cec611d: Mounted from library/ubuntud2bb1fc88136: Mounted from library/ubuntua6a01ad8b53f: Mounted from library/ubuntu833649a3e04c: Mounted from library/ubuntutesting: digest: sha256:286cb866f34a2aa85c9fd810ac2cedd87699c02731db1b8ca1cfad16ef17c146 size: 1569

Oh yeah! Your image is uploading. Once done, open DockerHub, log into your account, and you'll see your first Docker image. Now anyone can deploy your mirror. This is the easiest and fastest way to develop and distribute software. Whenever you update the mirror, users can simply run:

$ docker run arnieswap/my_repo Thank you for reading, the above is "how to download images from Docker Hub and run locally" content, after learning this article, I believe you have a deeper understanding of how to download images from Docker Hub and run locally This problem, the specific use needs to be verified by everyone. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
