在Termux+pRoot(AnLinux, Andronix)里跑不起来dockerd进程, 也跑不了任何x64程序/命令,
用alpine-term应用(https://github.com/diyism/alpine-term 578MB, 
https://github.com/sylirre/vmConsole 1.01GB)才行,
可以在它的docker里跑x86-64的docker image,用随身的arm64 android手机/平板就可以运行任何x64 docker app了

安装好后在alpine-term应用里执行sudo apk add -u go 会报错 untrsuted signature, 需要先:
sudo apk add -X https://dl-cdn.alpinelinux.org/alpine/v3.18/main -u alpine-keys --allow-untrusted
