Detailed explanation of the use of DockerHub image repository

Previously, the images we used were all pulled from the DockerHub public repository. We also learned how to make our own images, but backing up, restoring and migrating images through tar packages is not particularly friendly for team collaboration development. We can also push the images to the DockerHub repository for easy use.

Tips: If the built image contains project data, it is recommended to use a private repository.

Register an account

Official website: https://hub.docker.com/

Login Account

Use the docker login command to enter your account and password to log in to DockerHub.

Push the image to the warehouse

To facilitate testing, we pull the hello-world image locally and then upload it to the DockerHub repository.

First set the tag docker tag local-image:tagname new-repo:tagname for the image;

Then push the image to the repository docker push new-repo:tagname .

docker tag hello-world:latest mrhelloworld/test-hello-world:1.0.0
docker push mrhelloworld/test-hello-world:1.0.0 

View Warehouse

Pull the image

Test whether the image can be pulled by docker pull mrhelloworld/test-hello-world:1.0.0 .

Log out

Exit DockerHub using the docker logout command.

[root@localhost ~]# docker logout

This is the end of our learning on how to use the DockerHub image repository. Considering network reasons, the speed of downloading and uploading images from DockerHub may be slow. In addition, the Docker images used in production may contain our code, configuration information, etc., which we do not want to be obtained by outsiders, so only developers on the intranet are allowed to download them. How to solve it? This can be achieved by building a private image repository. Let's learn how to build a Docker private image repository below.
