Exercise 2.4 - Surveys

Read this in other languages: uk English, japan 日本語.

You might have noticed the ADD SURVEY button in the Template configuration view. A survey is a way to create a simple form to ask for parameters that get used as variables when a Template is launched as a Job.

You have installed Apache on all hosts in the job you just run. Now we’re going to extend on this:

Additionally, the role will also make sure that the Apache configuration is properly set up - in case it got mixed up during the other exercises.

Tip

The survey feature only provides a simple query for data - it does not support four-eye principles, queries based on dynamic data or nested menus.

The Apache-configuration Role

The Playbook and the role with the Jinja template already exist in the Github repository https://github.com/ansible/workshop-examples in the directory rhel/apache**`.

Head over to the Github UI and have a look at the content: the playbook apache_role_install.yml merely references the role. The role can be found in the roles/role_apache subdirectory.

What is this Playbook doing? It creates a file (dest) on the managed hosts from the template (src).

The role also deploys a static configuration for Apache. This is to make sure that all changes done in the previous chapters are overwritten and your examples work properly.

Because the Playbook and role is located in the same Github repo as the apache_install.yml Playbook you don’t have to configure a new project for this exercise.

Create a Template with a Survey

Now you create a new Template that includes a survey.

Create Template

Try for yourself, the solution is below.

Warning

Solution Below!

Warning

Do not run the template yet!

Add the Survey

Launch the Template

Now launch Create index.html job template.

Before the actual launch the survey will ask for First Line and Second Line. Fill in some text and click Next. The next window shows the values, if all is good run the Job by clicking Launch.

Tip

Note how the two survey lines are shown to the left of the Job view as Extra Variables.

After the job has completed, check the Apache homepage. In the SSH console on the control host, execute curl against the IP address of your node1:

$ curl http://22.33.44.55
<body>
<h1>Apache is running fine</h1>
<h1>This is survey field "First Line": line one</h1>
<h1>This is survey field "Second Line": line two</h1>
</body>

Note how the two variables where used by the playbook to create the content of the index.html file.

What About Some Practice?

Here is a list of tasks:

Please make sure to finish these steps as the next chapter depends on it!
