Tests run on Ubuntu 12.04
Travis is only using Ubuntu 12.04 for running the tests. I usually use Debian as distribution for my servers. So at least the same OS family to test on, but it is sad, that Travis let us not choose the OS. However, better than nothing.
Set up a playbook
First, we set up a simple playbook targeted to localhost and
include var files, tasks and handlers the new role, because otherwise ansible does not handle it as a role (dependencies, defaults):
--- - hosts: localhost remote_user: root roles: - ansible-role-ntp
This base playbook can be used in every role with no change. Use the name of your git repo for the role.
Because ansible would use the default
role_path to handle the role, the above playbook would not work. Therefore we make an ansible.cfg in the root path of the role in which we define the correct
[defaults] roles_path = ../
As you can see, we define the roles path to be the one directory level above.
Set up a .travis.yml
The travis file is also straigt forward. As we know, the test will run on Ubuntu, we also install some known dependencices by default, like
We install latest released ansible and set up the inventory. Then we check first for syntax errors and after this, we run the playbook.
To gain root permissions on Travis, we must use
--sudo, even though,
remote_user is set as
Further we use the a local connection and set verbosity to maximum. Note, We only use python 2.7 as we do not want to test ansible by itself.
--- language: python python: "2.7" before_install: - sudo apt-get update -qq - sudo apt-get install -qq python-apt python-pycurl install: - pip install ansible script: - echo localhost > inventory - ansible-playbook -i inventory --syntax-check role.yml - ansible-playbook -i inventory --connection=local --sudo -vvvv role.yml
If your role has dependendies defined in your
meta/main.yml you can simply install the dependencies in your install step using
... install: - pip install ansible - ansible-galaxy install <rolename> ...
Example Role ansible-role-ntp
As a working example, I show you my role for installing ntp, ansible-role-ntp. As you can see, I also intgrated the build status image in readme.
It is no magic using Travis to have a basic, automated test environment for Ubuntu. It gives you a good warm feeling if you change something and the tests pass, and this for free.
In the future, It would be great if we could also run the tests on several different OS’. Maybe Travis or even Ansibleworks will bring us this feature. Hint, Hint.
