arm linux compile

[icexiong1]

I am installing a Linux virtual machine on a host based on x64 Windows system. I want to use Docker to build a cross compilation environment inside the virtual machine (the development board is a Linux system based on armv8 kernel). Docker has already been installed on the virtual machine, but when using the Docker run -- rm arm648/ubuntu: 22.04 uname - p command to pull the image, I cannot find the image source. How can I solve this problem?
