# Looking at Chronos
I've decided to look at Chronos, a cron replacement running on Mesos.
Mesos
## Getting an environment
First I need to get an environment to play with it. Let's do that quickly with Vagrant and Ansible:
```ruby
Vagrant.configure("2") do |config|
config.ssh.forward_agent = true
config.vm.provision :ansible, :playbook => 'playbook.yml'
config.vm.provider :virtualbox do |vb, override|
override.vm.box = "precise64"
override.vm.box_url = "http://files.vagrantup.com/precise64.box"
end
end
```
And the playbook for Ansible:
```yaml
- hosts: all
sudo: yes
tasks:
- name: Install a bunch of packages
apt: pkg={{ item }} state=installed
with_items:
- autoconf
- make
- gcc
- cpp
- patch
- python-dev
- git
- libtool
- default-jdk
- default-jre
- gzip
- libghc-zlib-dev
- libcurl4-openssl-dev
```
Now I can run `vagrant up` and wait to get the VM build with everything I need.
