How to install the image searched by docker

When using Docker, sometimes you need to search for the required image in Docker Hub or other Docker image repositories to run or build applications. After you find the images you need, you need to know how to install and use them. In this article, we will show you step-by-step how to install a Docker-searched image.

First, you need to install Docker on your computer. If you haven't installed it yet, follow the steps at https://docs.docker.com/get-docker/ to install Docker.

You can then search for the desired image in Docker Hub or other Docker image repositories using the following command:

docker search <镜像名称>

For example, if you want to search for a MySQL image, you can run the following command:

docker search mysql

The search results will include all images matching this name. You will see each image's name, description, official or other host's logo, and other information.

To install the image you need, you need to use the following command:

docker pull <镜像名称>

For example, if you want to install the MySQL 5.7 version image, please run the following command:

docker pull mysql:5.7

This will download the image from Docker Hub and install it locally. Download time will depend on your network speed and the size of the image.

After the installation is complete, you can use the following command to view the installed images:

docker images

You will see a list of installed images, each image has a name, version, Docker Hub or Information such as tags, size, and creation time of other repositories.

Additionally, you can use the following command to start the installed image:

docker run <镜像名称>

To start the MySQL image, use the following command:

docker run mysql

By default, this will Create a MySQL instance and start it. If needed, you can use some additional settings to change the configuration of the MySQL instance, such as port, password, etc.

Through the above steps, you can easily search for the required images from Docker Hub or other Docker image repositories, and install and start them. This will greatly simplify your workflow during actual application development.
