My experience and problems in installing an HA image on virtualbox

1.I did this twice on different windows hosts and the procedure may differ greatly. The whole process might take as long as half an hour and I can only check if it’s close to completion by the virtual disk file’s size. When it comes to about 2GB, it’s about to be ok.
2. I don’t know why the ha command doesn’t work in my virtualbox’s shell. Each time I input an ha command and press enter, nothing happened but the help info shows again. I’m not sure it has anything to do with the docker?

Because the shell already runs the ha command.

ha > _

So if you want to run

ha core info


core info
