Attention: only tested on Mac with admin previlege

Pre-requisite

In order to use the Docker environment we provide, you will need two pre-requisite

Also, please make sure you have enough free memory (4GB) available.

Warning

For Windows Users: Install GIT bash for windows which include SSH for access to the VM.

Settings

The settings for the Vagrant VM are located in vagrantconfig.yaml. You can tweak them as necessary, such as adjusting the number_cpus or memory_size settings, to improve the performance of your VM.

Setup

With pre-requiste softwares properly installed, you could setup your Centos VM learning environment. Before you actually run commands, please make sure you have enough previlege. For example, virtual network adapter and network filesystem will be set up.

Warning

For Windows Users: You may need to configure line endings before running vagrant up so the VM is properly configured. You can do this as a gobal configuration with "git config --global core.autocrlf false", or only for a given repo by setting "* text eol=lf" in .gitattributes of that repo. Be sure to follow the directions for refreshing a repo after changing line endings, as documented here.

Open a terminal and you need to

Navigate to vm folder.
Run vagrant up to provision and run the VM.

(Note that the first run of vagrant up may take a long time. Please be patient.)

Connect

You could connect to master node by run vagrant ssh in vm folder. You will find all materials in /bootcamp folder.

Terminate

After you finish, you may want to terminate the virtual cluster. You could achieve that by

Navigate to vm folder.
Run vagrant destroy -f to destroy the VM.

Alternatively, you may just perform a graceful shutdown (without removing all traces of the virtual machine like above) by

Navigate to vm folder.
Run vagrant halt to gracefully shutdown the VM.
