Return Values¶
Topics
Ansible modules normally return a data structure that can be registered into a variable, or seen directly when output by the ansible program. Each module can optionally document its own unique return values (visible through ansible-doc and on the main docsite).
This document covers return values common to all modules.
Note
Some of these keys might be set by Ansible itself once it processes the module’s return information.
Common¶
backup_file¶
For those modules that implement backup=no|yes when manipulating files, a path to the backup file created.
"backup_file": "./foo.txt.32729.2020-07-30@06:24:19~"
changed¶
A boolean indicating if the task had to make changes to the target or delegated host.
"changed": true
diff¶
Information on differences between the previous and current state. Often a dictionary with entries before
and after
, which will then be formatted by the callback plugin to a diff view.
"diff": [ { "after": "", "after_header": "foo.txt (content)", "before": "", "before_header": "foo.txt (content)" }, { "after_header": "foo.txt (file attributes)", "before_header": "foo.txt (file attributes)" }
invocation¶
Information on how the module was invoked.
"invocation": { "module_args": { "_original_basename": "foo.txt", "attributes": null, "backup": true, "checksum": "da39a3ee5e6b4b0d3255bfef95601890afd80709", "content": null, "delimiter": null, "dest": "./foo.txt", "directory_mode": null, "follow": false, "force": true, "group": null, "local_follow": null, "mode": "666", "owner": null, "regexp": null, "remote_src": null, "selevel": null, "serole": null, "setype": null, "seuser": null, "src": "/Users/foo/.ansible/tmp/ansible-tmp-1596115458.110205-105717464505158/source", "unsafe_writes": null, "validate": null }
rc¶
Some modules execute command line utilities or are geared for executing commands directly (raw, shell, command, and so on), this field contains ‘return code’ of these utilities.
"rc": 257
results¶
If this key exists, it indicates that a loop was present for the task and that it contains a list of the normal module ‘result’ per item.
"results": [ { "ansible_loop_var": "item", "backup": "foo.txt.83170.2020-07-30@07:03:05~", "changed": true, "diff": [ { "after": "", "after_header": "foo.txt (content)", "before": "", "before_header": "foo.txt (content)" }, { "after_header": "foo.txt (file attributes)", "before_header": "foo.txt (file attributes)" } ], "failed": false, "invocation": { "module_args": { "attributes": null, "backrefs": false, "backup": true } }, "item": "foo", "msg": "line added" }, { "ansible_loop_var": "item", "backup": "foo.txt.83187.2020-07-30@07:03:05~", "changed": true, "diff": [ { "after": "", "after_header": "foo.txt (content)", "before": "", "before_header": "foo.txt (content)" }, { "after_header": "foo.txt (file attributes)", "before_header": "foo.txt (file attributes)" } ], "failed": false, "invocation": { "module_args": { "attributes": null, "backrefs": false, "backup": true } }, "item": "bar", "msg": "line added" } ]
stderr¶
Some modules execute command line utilities or are geared for executing commands directly (raw, shell, command, and so on), this field contains the error output of these utilities.
"stderr": "ls: foo: No such file or directory"
stderr_lines¶
When stderr is returned we also always provide this field which is a list of strings, one item per line from the original.
"stderr_lines": [ "ls: doesntexist: No such file or directory" ]
stdout¶
Some modules execute command line utilities or are geared for executing commands directly (raw, shell, command, and so on). This field contains the normal output of these utilities.
"stdout": "foo!"
stdout_lines¶
When stdout is returned, Ansible always provides a list of strings, each containing one item per line from the original output.
"stdout_lines": [ "foo!" ]
Internal use¶
These keys can be added by modules but will be removed from registered variables; they are ‘consumed’ by Ansible itself.
ansible_facts¶
This key should contain a dictionary which will be appended to the facts assigned to the host. These will be directly accessible and don’t require using a registered variable.
exception¶
This key can contain traceback information caused by an exception in a module. It will only be displayed on high verbosity (-vvv).
deprecations¶
This key contains a list of dictionaries that will be presented to the user. Keys of the dictionaries are msg and version, values are string, value for the version key can be an empty string.
