Can you elaborate on this? This seems like a simple problem, but not in ansible. It keeps coming up. Especially in error conditions. I need a global variable.

One that I can set when processing one host play, then check at a later time with another host. In a nutshell, so I can branch later in the playbook, depending on the variable. We have no control over custom software installation, but if it is installed, we have to put different software on other machines. To top it off, the installations vary, depending on the VM folder.

My kingdom for a global var. I understand the scope of variables, but I want to SET a global variable that can be read throughout all playbook plays. The actual implementation is unimportant but variable access is important. My Question: Is there a way to set a variable that can be checked when running a different task on another host?

Something like setGlobalSpaceVar myvar, true? I know there isn't any such method, but I'm looking for a work-around.

Rephrasing: set a variable in one tasks for one host, then later in another task for another host, read that variable. The following relates to oracle backups and our local executable, but I'm keeping it generic.

This variable access problem keeps coming up in different contexts. I have 4 xyz servers. I have 2 programs that need to be executed, but only on 2 different machines. I don't know which.

The settings may be change for different VM environments.This module is part of ansible-base and included in all Ansible installations. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name. Set cacheable to yes to save variables across executions using a fact cache. Per the standard Ansible variable precedence rules, many other types of variables have a higher priority, so this value may be overridden.

Ansible 2. New in version 1. Variables are set on a host-by-host basis just like facts discovered by the setup module. These variables will be available to subsequent plays during an ansible-playbook run. This module is also supported for Windows targets.

This boolean converts the variable into an actual 'fact' which will also be added to the fact cache, if fact caching is enabled. Normally this module creates 'host level variables' and has much higher precedence, this option changes the nature and precedence by 7 steps of the variable created. Or alternatively, accepts complex arguments using the args: statement. Variable precedence: Where should I put a variable?

Possible values: all, hardware, network, virtual, ohai, and facter Can specify a list of values to specify a larger subset. Values can also be used with an initial! For instance:! Note that a few facts are always collected. Use the filter parameter if you do not want to display those. If facter or ohai are installed, variables from these programs will also be snapshotted into the JSON file for usage in templating. All variables are bubbled up to the caller.

Using the ansible facts and choosing to not install facter and ohai means you can avoid Ruby-dependencies on your remote systems. See also facter and ohai. If the target host is Windows, you will not currently have the ability to use filter as this is provided by a simpler implementation of the module. Make sure that this path exists on the target host.
