Inside a template you automatically have access to all variables that are in scope for a host. I encountered this problem in a setup where I needed to create multiple deployment environments live, demo, sandbox to the same physical server not allowed virtual machines here , and then a script to deploy arbitrary svn repos This required a directory tree of optional variable. Ansible is designed so that its configuration is clear and easy to follow even for new users. The ansible-vault view command feeds the contents of a file to standard out. Group intersection, however, brings serious problems for this system. This command is used to initially encrypt files and is subsequently used to view, edit, or decrypt the data. However, what if you want to have a simple way to provide system or user provided data for use in Ansible variables, without writing a fact module? Maybe you can use my plugin as a base and implement deep merging or directly a real include.

This is secure, but our implementation has affected our usability. To do that open the vars file and make the following changes. For this to work properly, when running playbooks, the directory where the main playbook resides shall be the current directory. So you need to try something extra like jq after trimming the output to make it valid json. Playbook imports, when used, shall use paths relative to the main playbook directory. There are a few other things that go on with roles. Vault is a mechanism that allows encrypted content to be incorporated transparently into Ansible workflows.

Share your use case and approach in the comments below.

To make things explicit, it is suggested that you set them if things are not running on the default port:. Other useful magic variables refer to the current play or playbook, including: New in version 2.

The following example shows a good way to do this. Variable precedence is detailed in. Point to the location of your password file.

This variable defaults to 1 if not set. One limitation is the inability to select all hosts by function across environments. Currently, Ansible ships with two persistent cache plugins: redis and jsonfile. They can be used to loop through a set of given values, access various information like the hostname of a system and replace certain strings in templates by system specific values. Tip: The ansible-playbook command looks for playbooks in the current working directory by default.

Your development servers will likely be smaller than your production servers. More importantly, relying on these techniques makes them mandatory. Upon saving, the new contents will be encrypted using the file's encryption password again and written to disk. This is again a simple example, but shows the basics: in templates variables are also referenced by {{ }}. Together with templates and the Jinja2 template and language engine the possibilities are almost endless. But note that variable names have some restrictions in Ansible: Variable names should be letters, numbers, and underscores.
