module: win_template
|
|
short_description: Template a file out to a remote server
|
|
description:
|
|
- Templates are processed by the L(Jinja2 templating language,http://jinja.pocoo.org/docs/).
|
|
- Documentation on the template formatting can be found in the
|
|
L(Template Designer Documentation,http://jinja.pocoo.org/docs/templates/).
|
|
- Additional variables listed below 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) is the numeric user id of the owner.
|
|
- C(template_path) is the path of the template.
|
|
- C(template_fullpath) is the absolute path of the template.
|
|
- C(template_destpath) is the path of the template on the remote system (added in 2.8).
|
|
- C(template_run_date) is the date that the template was rendered.
|
|
options:
|
|
backup:
|
|
description:
|
|
- Determine whether a backup should be created.
|
|
- When set to C(yes), create a backup file including the timestamp information
|
|
so you can get the original file back if you somehow clobbered it incorrectly.
|
|
type: bool
|
|
default: no
|
|
block_end_string:
|
|
description:
|
|
- The string marking the end of a block.
|
|
type: str
|
|
default: '%}'
|
|
block_start_string:
|
|
description:
|
|
- The string marking the beginning of a block.
|
|
type: str
|
|
default: '{%'
|
|
dest:
|
|
description:
|
|
- Location to render the template to on the remote machine.
|
|
type: path
|
|
required: yes
|
|
force:
|
|
description:
|
|
- Determine when the file is being transferred if the destination already exists.
|
|
- When set to C(yes), replace the remote file when contents are different than the source.
|
|
- When set to C(no), the file will only be transferred if the destination does not exist.
|
|
type: bool
|
|
default: yes
|
|
lstrip_blocks:
|
|
description:
|
|
- Determine when leading spaces and tabs should be stripped.
|
|
- When set to C(yes) leading spaces and tabs are stripped from the start of a line to a block.
|
|
- This functionality requires Jinja 2.7 or newer.
|
|
type: bool
|
|
default: no
|
|
newline_sequence:
|
|
description:
|
|
- Specify the newline sequence to use for templating files.
|
|
type: str
|
|
choices: [ '\n', '\r', '\r\n' ]
|
|
default: '\r\n'
|
|
output_encoding:
|
|
description:
|
|
- Overrides the encoding used to write the template file defined by C(dest).
|
|
- It defaults to C(utf-8), but any encoding supported by python can be used.
|
|
- The source template file must always be encoded using C(utf-8), for homogeneity.
|
|
type: str
|
|
default: utf-8
|
|
src:
|
|
description:
|
|
- Path of a Jinja2 formatted template on the Ansible controller.
|
|
- This can be a relative or an absolute path.
|
|
- The file must be encoded with C(utf-8) but I(output_encoding) can be used to control the encoding of the output
|
|
template.
|
|
type: path
|
|
required: yes
|
|
trim_blocks:
|
|
description:
|
|
- Determine when newlines should be removed from blocks.
|
|
- When set to C(yes) the first newline after a block is removed (block, not variable tag!).
|
|
type: bool
|
|
default: yes
|
|
variable_end_string:
|
|
description:
|
|
- The string marking the end of a print statement.
|
|
type: str
|
|
default: '}}'
|
|
variable_start_string:
|
|
description:
|
|
- The string marking the beginning of a print statement.
|
|
type: str
|
|
default: '{{'
|
|
notes:
|
|
- Including a string that uses a date in the template will result in the template being marked 'changed' each time.
|
|
- >
|
|
Also, you can override jinja2 settings by adding a special header to template file.
|
|
i.e. C(#jinja2:variable_start_string:'[%', variable_end_string:'%]', trim_blocks: False)
|
|
which changes the variable interpolation markers to C([% var %]) instead of C({{ var }}).
|
|
This is the best way to prevent evaluation of things that look like, but should not be Jinja2.
|
|
- Using raw/endraw in Jinja2 will not work as you expect because templates in Ansible are recursively
|
|
evaluated.
|
|
- To find Byte Order Marks in files, use C(Format-Hex <file> -Count 16) on Windows, and use C(od -a -t x1 -N 16 <file>)
|
|
on Linux.
|
|
- Beware fetching files from windows machines when creating templates because certain tools, such as Powershell ISE,
|
|
and regedit's export facility add a Byte Order Mark as the first character of the file, which can cause tracebacks.
|
|
- You can use the M(ansible.windows.win_copy) module with the C(content:) option if you prefer the template inline, as part of the
|
|
playbook.
|
|
- For Linux you can use M(ansible.builtin.template) which uses '\\n' as C(newline_sequence) by default.
