With the continuous development of Docker technology, Docker images have become one of the cornerstones of modern application development. Alibaba Cloud is a world-renowned cloud computing service provider, and the Docker image it provides is also very famous. However, due to various reasons, not everyone can use Alibaba Cloud services. So how can non-Alibaba users use Alibaba Docker images? This article will tell you some relevant knowledge points.
The first step is of course to download the corresponding Docker image. The address of Alibaba Cloud's Docker image warehouse is registry.cn-hangzhou.aliyuncs.com. You first need to download the Alibaba Cloud image. Assuming that you want to download the latest version of MySQL, the download command is:
docker pull registry.cn-hangzhou.aliyuncs.com/library/mysql:latest
In the above command, registry.cn-hangzhou.aliyuncs.com is the registry address of Alibaba Cloud, and library/mysql is the registry address of MySQL. The official image name, latest is the label of the image, that is, the version number.
After the download is completed, you can run the image in the local Docker environment:
docker run --name=mysql -d -e MYSQL_ROOT_PASSWORD=123456 registry.cn-hangzhou.aliyuncs.com/library/mysql:latest
The above command is used to start a MySQL container. The -d parameter indicates running the container in background mode. The -e parameter indicates setting the root user's password, the --name parameter indicates naming the container, and the last parameter is the MySQL image name and label.
It should be noted that if the local Docker environment cannot connect to Alibaba Cloud's Docker Registry, you need to configure Docker's image accelerator. Alibaba Cloud provides a specialized mirror accelerator service, which can be configured using the following command:
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://5c5d9e66.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
In the above command, the registry-mirrors parameter is used to set the address of the mirror accelerator. The image accelerator address of Alibaba Cloud is used here.
In addition, it should be noted that Alibaba Cloud's Docker image may have some changes, such as changes in image name, image label, etc. Therefore, it is recommended to go to Alibaba Cloud's Docker Hub to view relevant documents and instructions before use.
In short, although you are not an Alibaba Cloud user, you can still use Alibaba Cloud's Docker image. As long as you master the above basic knowledge points, you can use it happily.
