In order to launch and access instance:
$ cd acc_training
$ vagrant up
$ vagrant ssh
For provisioned items check provision.sh.
For opened ports check Vagrantfile config.vm.network part.
To increase memory - adjust vb.memory block.
To get bash examples from within vagrant do:
$ cp -r /vagrant/learn_bash ~/
This will copy bash scripts to home directory.
