Download the image, then upload it to the server and use the local image. For detailed instructions, refer to the deployment section on the official website. If you still have questions after reading the deployment guide, you might need to learn some Linux basics. I recommend checking out “The Linux Command Line” by William Shotts. Many of the first batch of Linux administrators in China have it in their collections.
