ansible_spec
This is a Ruby gem that implements an Ansible Config Parser for Serverspec. It creates a Rake task that can run tests, using Ansible inventory files and playbooks. You can test multiple roles and multiple hosts.
Features
- Supports Serverspec v2
- Supports special host variables
ansible_ssh_portoransible_portansible_ssh_useroransible_useransible_ssh_hostoransible_hostansible_ssh_private_key_file
- Supports host patterns/ranges -- e.g.:
www[01:50].example.com - Supports Ansible dynamic inventory sources
Installation
$ gem install ansible_spec
Usage
Create Rakefile & spec/spec_helper.rb
$ ansiblespec-init
create spec
create spec/spec_helper.rb
create Rakefile
create .ansiblespec
create .rspec
[Optional] .ansiblespec
By default, site.yml will be used as the playbook and hosts as the
inventory file. You can either follow these conventions or you can
customize the playbook and inventory using an .ansiblespec file.
---
-
playbook: site.yml
inventory: hosts
vars_dirs_path: inventories/staging
hash_behaviour: merge
[Optional] Environment variables
You can use environment variables with the rake command. They are listed below.
PLAYBOOK-- playbook name (e.g.site.yml)INVENTORY-- inventory file name (e.g.hosts)VARS_DIRS_PATH-- directory path containing the group_vars and host_vars directories (e.g.inventories/staging)HASH_BEHAVIOUR-- hash behaviour when duplicate hash variables (e.g.merge)SSH_CONFIG_FILE-- ssh configuration file path (e.g.ssh_config)
SSH_CONFIG_FILEtake precedence over the path at ssh_args( -F "filename") in [ssh_connection] section of ansible.cfg
Environment variables take precedence over the .ansiblespec file.
Example:
$ PLAYBOOK=site.yml INVENTORY=hosts rake serverspec:Ansible-Sample-TDD
or
$ PLAYBOOK=site.yml rake serverspec:Ansible-Sample-TDD
or
$ INVENTORY=hosts rake serverspec:Ansible-Sample-TDD
or
$ VARS_DIRS_PATH=inventories/staging rake serverspec:Ansible-Sample-TDD
or
$ HASH_BEHAVIOUR=merge rake serverspec:Ansible-Sample-TDD
HASH_BEHAVIOUR is same as Ansible's hash behaviour parameter. By default, 'replace'. See http://docs.ansible.com/ansible/intro_configuration.html#hash-behaviour.
Inventory
Inventory files can:
- use standard ansible parameters
ansible_ssh_portoransible_portansible_ssh_useroransible_useransible_ssh_hostoransible_hostansible_ssh_private_key_file
- define hosts as expressions.
host-[1:3]would expand intohost-1,host-2,host-3 - Group Children
- Use dynamic inventory sources
Sample
[server]
# skip line(comment)
# normal
192.168.0.1
# use port 5309
192.168.0.3:5309
# use port 22

# use Private-key ~/.ssh/id_rsa

# use user `git`

# use port 5555 & host 192.168.1.50
jumper ansible_ssh_port=5555 ansible_ssh_host=192.168.1.50

[web]
# www1.example.com to www99.example.com

# www01.example.com to www99.example.com
www[01:99].example.com
[databases]
# db-a.example.com to db-z.example.com
db-[a:z].example.com
# db-A.example.com to db-Z.example.com
db-[A:Z].example.com
# Multi Group. use server & databases
[parent:children]

Dynamic Inventory Sources
(Note: These files need to have execute permission)
#!/bin/bash
echo '{"databases": {"hosts": ["host1.example.com", "host2.example.com"],"vars":{"a": true}}}'
Variables
Ansible variables supported by following condition.
- Playbook's variables are supported. If same variable is defined in different places, priority follows Ansible order.
- Variables defined main.yml in role's tasks are not supported.
- Inventory variables are not supported.
- Facts are not supported.
SSH config priority (from v0.2.23)
- ENV['SSH_CONFIG_FILE'] (high priority)
- ssh_args( -F "filename") in [ssh_connection] section of ansible.cfg
- user from site.yml
- ~/.ssh/config (low priority)
Sample
Support variables are in site.yml, group_vars, host_vars, roles.
