RSpec tests for Service Dependencies

USAGE

1. Install the gem

gem install svcdeps_tasks

2. Add the following to Rakefile:

require 'svcdeps_tasks'

ENV['SVCDEPS_PATH'] = '/etc/svcdeps'

3. Create a directory for dependencies manifests, /ec/svcdeps in our case:

mkdir /etc/svcdeps

4. Create dependencies manifests, which are yaml files describing how to check the service dependencies:

deps: 
  - type: tcp
    host: www.google.com
    port: 80
    timeout: 2
    desc: Should be able to tcp port ping www.google.com:80
    
  - type: udp
    host: 8.8.8.8
    port: 53
    timeout: 2
    desc: Should be able to udp port ping DNS server(8.8.8.8:53)

  - type: http
    method: get
    url: https://www.google.com
    insecure: false
    timeout: 2
    desc: Should be able to hit https://www.google.com
    
  - type: command
    command: ping -c 1 8.8.8.8
    timeout: 2 
    desc: Should be able to ping 8.8.8.8

5. Run:

# rake spec:svcdeps

Service Dependencies
  Should be able to tcp port ping www.google.com:80
  Should be able to udp port ping DNS server(8.8.8.8:53)
