Ansible Configuration Settings

Ansible Configuration Settings

Ansible supports several sources for configuring its behavior, including an ini file named ansible.cfg, environment variables, command-line options, playbook keywords, and variables. See Controlling how Ansible behaves: precedence rules for details on the relative precedence of each source.

The ansible-config utility allows users to see all the configuration settings available, their defaults, how to set them andwhere their current value comes from. See ansible-config for more information.

The configuration file

Changes can be made and used in a configuration file which will be searched for in the following order:

ANSIBLE_CONFIG (environment variable if set)
ansible.cfg (in the current directory)
~/.ansible.cfg (in the home directory)
/etc/ansible/ansible.cfg

Ansible will process the above list and use the first file found, all others are ignored.

Note

The configuration file is one variant of an INI format.Both the hash sign (#) and semicolon (;) are allowed ascomment markers when the comment starts the line.However, if the comment is inline with regular values,only the semicolon is allowed to introduce the comment.For instance:

# some basic default values...
inventory = /etc/ansible/hosts  ; This points to the file that lists your hosts

Avoiding security risks with ansible.cfg in the current directory

If Ansible were to load ansible.cfg from a world-writable current workingdirectory, it would create a serious security risk. Another user could placetheir own config file there, designed to make Ansible run malicious code bothlocally and remotely, possibly with elevated privileges. For this reason,Ansible will not automatically load a config file from the current workingdirectory if the directory is world-writable.

If you depend on using Ansible with a config file in the current workingdirectory, the best way to avoid this problem is to restrict access to yourAnsible directories to particular user(s) and/or group(s). If your Ansibledirectories live on a filesystem which has to emulate Unix permissions, likeVagrant or Windows Subsystem for Linux (WSL), you may, at first, not know howyou can fix this as chmod, chown, and chgrp might not work there.In most of those cases, the correct fix is to modify the mount options of thefilesystem so the files and directories are readable and writable by the usersand groups running Ansible but closed to others. For more details on thecorrect settings, see:

for Vagrant, Jeremy Kendall’s blog post covers synced folder permissions.
for WSL, the WSL docsand this Microsoft blog post cover mount options.

If you absolutely depend on storing your Ansible config in a world-writable currentworking directory, you can explicitly specify the config file via theANSIBLE_CONFIG environment variable. Please takeappropriate steps to mitigate the security concerns above before doing so.

Relative paths for configuration

You can specify a relative path for many configuration options. In most ofthose cases the path used will be relative to the ansible.cfg file usedfor the current execution. If you need a path relative to your current workingdirectory (CWD) you can use the {{CWD}} macro to specifyit. We do not recommend this approach, as using your CWD as the root ofrelative paths can be a security risk. For example:cd /tmp; secureinfo=./newrootpassword ansible-playbook ~/safestuff/change_root_pwd.yml.

Common Options

This is a copy of the options available from our release, your local install might have extra options due to additional plugins,you can use the command line utility mentioned above (ansible-config) to browse through those.

Environment:	`ANSIBLE_NOCOWS`

ANSIBLE_PIPELINING

Description:	Pipelining, if supported by the connection plugin, reduces the number of network operations required to execute a module on the remote server, by executing many Ansible modules without actual file transfer. This can result in a very significant performance improvement when enabled. However this conflicts with privilege escalation (become). For example, when using ‘sudo:’ operations you must first disable ‘requiretty’ in /etc/sudoers on all managed hosts, which is why it is disabled by default. This options is disabled if `ANSIBLE_KEEP_REMOTE_FILES` is enabled.

Type:	boolean
Default:	True
Version Added:	1.8
Ini Section:	defaults
Ini Key:	command_warnings
Environment:	`ANSIBLE_COMMAND_WARNINGS`

CONDITIONAL_BARE_VARS

Description:	With this setting on (True), running conditional evaluation ‘var’ is treated differently than ‘var.subkey’ as the first is evaluated directly while the second goes through the Jinja2 parser. But ‘false’ strings in ‘var’ get evaluated as booleans. With this setting off they both evaluate the same but in cases in which ‘var’ was ‘false’ (a string) it won’t get evaluated as a boolean anymore. Currently this setting defaults to ‘True’ but will soon change to ‘False’ and the setting itself will be removed in the future. Expect the default to change in version 2.10 and that this setting eventually will be deprecated after 2.12
Type:	boolean

DEFAULT_ALLOW_UNSAFE_LOOKUPS

Description:	When enabled, this option allows lookup plugins (whether used in variables as `{{lookup('foo')}}` or as a loop as with_foo) to return data that is not marked ‘unsafe’. By default, such data is marked as unsafe to prevent the templating engine from evaluating any jinja2 templating language, as this could represent a security risk. This option is provided to allow for backwards-compatibility, however users should first consider adding allow_unsafe=True to any lookups which may be expected to contain data which may be run through the templating engine late
Type:	boolean
Default:	False
Version Added:	2.2.3
Ini Section:	defaults
Ini Key:	allow_unsafe_lookups

Type:	boolean
Default:	False
Ini Section:	defaults
Ini Key:	debug
Environment:	`ANSIBLE_DEBUG`

DEFAULT_EXECUTABLE

Description:	This indicates the command to use to spawn a shell under for Ansible’s execution needs on a target. Users may need to change this in rare instances when shell usage is constrained, but in most cases it may be left as is.
Default:	/bin/sh
Ini Section:	defaults
Ini Key:	executable
Environment:	`ANSIBLE_EXECUTABLE`

DEFAULT_FACT_PATH

Description:	This option allows you to globally configure a custom path for ‘local_facts’ for the implied M(setup) task when using fact gathering. If not set, it will fallback to the default from the M(setup) module: `/etc/ansible/facts.d`. This does not affect user defined tasks that use the M(setup) module.
Type:	path

Type:	integer
Default:	10
Ini Section:	defaults
Ini Key:	gather_timeout
Environment:	`ANSIBLE_GATHER_TIMEOUT`

DEFAULT_GATHERING

Description:	This setting controls the default policy of fact gathering (facts discovered about remote systems). When ‘implicit’ (the default), the cache plugin will be ignored and facts will be gathered per play unless ‘gather_facts: False’ is set. When ‘explicit’ the inverse is true, facts will not be gathered unless directly requested in the play. The ‘smart’ value means each new host that has no facts discovered will be scanned, but if the same host is addressed in multiple plays it will not be contacted again in the playbook run. This option can be useful for those wishing to save fact gathering time. Both ‘smart’ and ‘explicit’ will use the cache plugin.
Default:	implicit
Version Added:	1.6
Ini Section:	defaults
Ini Key:	gathering
Environment:	`ANSIBLE_GATHERING`

DEFAULT_HANDLER_INCLUDES_STATIC

Deprecated detail:
Description:	Since 2.0 M(include) can be ‘dynamic’, this setting (if True) forces that if the include appears in a `handlers` section to be ‘static’.
Type:	boolean
Default:	False

Environment:	`ANSIBLE_HANDLER_INCLUDES_STATIC`
Deprecated in:	2.12
	include itself is deprecated and this setting will not matter in the future
Deprecated alternatives:
	none as its already built into the decision between include_tasks and import_tasks

DEFAULT_HASH_BEHAVIOUR

Description:	This setting controls how variables merge in Ansible. By default Ansible will override variables in specific precedence orders, as described in Variables. When a variable of higher precedence wins, it will replace the other value. Some users prefer that variables that are hashes (aka ‘dictionaries’ in Python terms) are merged. This setting is called ‘merge’. This is not the default behavior and it does not affect variables whose values are scalars (integers, strings) or arrays. We generally recommend not using this setting unless you think you have an absolute need for it, and playbooks in the official examples repos do not use this setting In version 2.0 a `combine` filter was added to allow doing this for a particular variable (described in Filters).
Type:	string
Default:	replace

DEFAULT_INTERNAL_POLL_INTERVAL

Description:	This sets the interval (in seconds) of Ansible internal processes polling each other. Lower values improve performance with large playbooks at the expense of extra CPU load. Higher values are more suitable for Ansible usage in automation scenarios, when UI responsiveness is not required but CPU usage might be a concern. The default corresponds to the value hardcoded in Ansible <= 2.1

DISPLAY_ARGS_TO_STDOUT

Description:	Normally `ansible-playbook` will print a header for each task that is run. These headers will contain the name: field from the task if you specified one. If you didn’t then `ansible-playbook` uses the task’s action to help you tell which task is presently running. Sometimes you run many of the same action and so you want more information about the task to differentiate it from others of the same action. If you set this variable to True in the config then `ansible-playbook` will also include the task’s arguments in the header. This setting defaults to False because there is a chance that you have sensitive values in your parameters and you do not want those to be printed. If you set this to True you should be sure that you have secured your environment’s stdout (no one can shoulder surf your screen and you aren’t saving stdout to an insecure file) or made sure that all of your playbooks explicitly added the `no_log: True` parameter to tasks which have sensitive values See How do I keep secret data in my playbook? for more information.

INTERPRETER_PYTHON

Description:	Path to the Python interpreter to be used for module execution on remote targets, or an automatic discovery mode. Supported discovery modes are `auto`, `auto_silent`, and `auto_legacy` (the default). All discovery modes employ a lookup table to use the included system Python (on distributions known to include one), falling back to a fixed ordered list of well-known Python interpreter locations if a platform-specific default is not available. The fallback behavior will issue a warning that the interpreter should be set explicitly (since interpreters installed later may change which one is used). This warning behavior can be disabled by setting `auto_silent`. The default value of `auto_legacy` provides all the same behavior, but for backwards-compatibility with older Ansible releases that always defaulted to `/usr/bin/python`, will use that interpreter if present (and issue a warning that the default behavior will change to that of `auto` in a future Ansible release.
