Description

Templates are processed by the Jinja2 templating language (U(http://jinja.pocoo.org/docs/)) - documentation on the template formatting can be found in the Template Designer Documentation (U(http://jinja.pocoo.org/docs/templates/)).

Six additional variables can be used in templates: C(ansible_managed) (configurable via the C(defaults) section of C(ansible.cfg)) contains a string which can be used to describe the template name, host, modification time of the template file and the owner uid. C(template_host) contains the node name of the template's machine. C(template_uid) the numeric user id of the owner. C(template_path) the path of the template. C(template_fullpath) is the absolute path of the template. C(template_run_date) is the date that the template was rendered.

Usage examples

  • Success

# Example from Ansible Playbooks
- template:

  • Success
    Steampunk Spotter scan finished with no errors, warnings or hints.

Inputs

    
src:
    description:
    - Path of a Jinja2 formatted template on the Ansible controller. This can be a relative
      or absolute path.
    required: true

dest:
    description:
    - Location to render the template to on the remote machine.
    required: true

mode:
    description:
    - The permissions the resulting filesystem object should have.
    - For those used to I(/usr/bin/chmod) remember that modes are actually octal numbers.
      You must give Ansible enough information to parse them correctly. For consistent
      results, quote octal numbers (for example, V('644') or V('1777')) so Ansible receives
      a string and can do its own conversion from string into number. Adding a leading
      zero (for example, V(0755)) works sometimes, but can fail in loops and some other
      circumstances.
    - Giving Ansible a number without following either of these rules will end up with
      a decimal number which will have unexpected results.
    - As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, V(u+rwx)
      or V(u=rw,g=r,o=r)).
    - If O(mode) is not specified and the destination filesystem object B(does not) exist,
      the default C(umask) on the system will be used when setting the mode for the newly
      created filesystem object.
    - If O(mode) is not specified and the destination filesystem object B(does) exist,
      the mode of the existing filesystem object will be used.
    - Specifying O(mode) is the best way to ensure filesystem objects are created with
      the correct permissions. See CVE-2020-1736 for further details.
    type: raw

force:
    choices:
    - 'yes'
    - 'no'
    default: 'yes'
    description:
    - the default is C(yes), which will replace the remote file when contents are different
      than the source.  If C(no), the file will only be transferred if the destination
      does not exist.
    required: false

group:
    description:
    - Name of the group that should own the filesystem object, as would be fed to I(chown).
    - When left unspecified, it uses the current group of the current user unless you
      are root, in which case it can preserve the previous ownership.
    type: str

owner:
    description:
    - Name of the user that should own the filesystem object, as would be fed to I(chown).
    - When left unspecified, it uses the current user unless you are root, in which case
      it can preserve the previous ownership.
    - Specifying a numeric username will be assumed to be a user ID and not a username.
      Avoid numeric usernames to avoid this confusion.
    type: str

backup:
    choices:
    - 'yes'
    - 'no'
    default: 'no'
    description:
    - Create a backup file including the timestamp information so you can get the original
      file back if you somehow clobbered it incorrectly.
    required: false

serole:
    description:
    - The role part of the SELinux filesystem object context.
    - When set to V(_default), it will use the C(role) portion of the policy if available.
    type: str

setype:
    description:
    - The type part of the SELinux filesystem object context.
    - When set to V(_default), it will use the C(type) portion of the policy if available.
    type: str

seuser:
    description:
    - The user part of the SELinux filesystem object context.
    - By default it uses the V(system) policy, where applicable.
    - When set to V(_default), it will use the C(user) portion of the policy if available.
    type: str

selevel:
    description:
    - The level part of the SELinux filesystem object context.
    - This is the MLS/MCS attribute, sometimes known as the C(range).
    - When set to V(_default), it will use the C(level) portion of the policy if available.
    type: str

validate:
    description:
    - The validation command to run before copying the updated file into the final destination.
    - A temporary file path is used to validate, passed in through '%s' which must be
      present as in the examples below.
    - Also, the command is passed securely so shell features such as expansion and pipes
      will not work.
    - For an example on how to handle more complex validation than what this option provides,
      see R(handling complex validation,complex_configuration_validation).
    type: str

attributes:
    aliases:
    - attr
    description:
    - The attributes the resulting filesystem object should have.
    - To get supported flags look at the man page for I(chattr) on the target system.
    - This string should contain the attributes in the same order as the one displayed
      by I(lsattr).
    - The C(=) operator is assumed as default, otherwise C(+) or C(-) operators need to
      be included in the string.

unsafe_writes:
    default: false
    description:
    - Influence when to use atomic operation to prevent data corruption or inconsistent
      reads from the target filesystem object.
    - By default this module uses atomic operations to prevent data corruption or inconsistent
      reads from the target filesystem objects, but sometimes systems are configured or
      just broken in ways that prevent this. One example is docker mounted filesystem
      objects, which cannot be updated atomically from inside the container and can only
      be written in an unsafe manner.
    - This option allows Ansible to fall back to unsafe methods of updating filesystem
      objects when atomic operations fail (however, it doesn't force Ansible to perform
      unsafe writes).
    - IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption.
