deploy states for SaltStacks
for more info on SaltStack: http://saltstack.com/community.html Salt is a master-minion system to setup servers and workstations to specified states, defined in yaml files.
Incredibly handy for setting up once for testing, development and production.
sudo add-apt-repository ppa:saltstack/salt
(if using Saucy 13.10):
sudo add-apt-repository ppa:saltstack/salt-daily
Vagrant is a virtual deploy and setup tool that can use Salt as provisioner to setup a machine in Virtualbox. All you need is a Vagrantfile and the salt config files. You don't need to install salt to use, it will be installed on virtual image.
- download from http://downloads.vagrantup.com/ and install.
Typical structure:
── koha ( root dir, often shared dir in Vagrant and including Vagrantfile )
├── pillar
│ ├── koha
│ │ └── init.sls
│ └── top.sls
├── salt
│ ├── koha
│ │ ├── files ( files exposed to salt, accessible by salt://koha/files)
│ │ │ ├── sample_template.tmpl
│ │ │ ├── any_file_really.sh
│ │ │ ├── ...
│ │ ├── init.sls
│ │ ├── examplestate.sls ( example state - can be loaded on start or manually )
│ │ ├── ...
│ ├── minion ( minion settings, can include variables, etc. )
│ └── top.sls ( top state file - loads when booting image)
└── Vagrantfile ( Vagrant setup file, virtualbox image, provisioner, forwarded ports, etc.)
The core config file for Vagrant. Any commands to Vagrant must be run from dir with Vagrantfile.
NB! For running 64bit virtual images, the processor needs to support virtualization:
check with:
grep --color vmx /proc/cpuinfo
if there is output with vmx it's Yay!
Usually, the commands are:
vagrant up ( builds virtualbox from net image or uses previous one located in .vagrant,
boots virtualbox and runs state.highstate (=top.sls) if given in Vagrantfile)
vagrant halt/reload (stops/reboots virtualbox)
vagrant destroy ( deletes virtualbox entirely )
vagrant provision ( forces running state.highstate )
vagrant ssh ( log into virtualbox and do whatever as sudo! )
To run individual states, run e.g.:
echo "sudo salt-call state.sls examplestate" | vagrant ssh
Or do it from within the Virtualbox
