Usage:
$ vagrant_run <vagrant-vhost-folder-short-name> [vhost-name] [up | halt | destroy...]
$ vagrant_run <vhost-name> [up | halt]
$ vagrant_run ls|list
For example:
$ vagrant_run ub20a
~ub20a is a hash -d name which points to somewhere who owns a Vagrantfile.
$ vagrant_run ub20a halt
$ vagrant_run ub20a up
$ vagrant_run redis-va redis01
~refis-va is a hash -d name which points to somewhere who owns a Vagrantfile.
There are multiple vhosts defined in the Vagrantfile (via `nodes = Hash.new\n...`)
$ vagrant_run redis-va redis01 up
$ vagrant_run redis-va redis01 halt
$ vagrant_run ls
$ vagrant_run ubuntu20testvm up # a virtualbox vm
Known VMs:
- ub20a :
- redis-va : k8s, ops, study and develop
