module: iso_extract
|
||||
short_description: Extract files from an ISO image
|
||||
description:
|
||||
- This module has two possible ways of operation.
|
||||
- If 7zip is installed on the system, this module extracts files from an ISO
|
||||
into a temporary directory and copies files to a given destination,
|
||||
if needed.
|
||||
- If the user has mount-capabilities (CAP_SYS_ADMIN on Linux) this module
|
||||
mounts the ISO image to a temporary location, and copies files to a given
|
||||
destination, if needed.
|
||||
requirements:
|
||||
- Either 7z (from C(7zip) or C(p7zip) package)
|
||||
- Or mount capabilities (root-access, or CAP_SYS_ADMIN capability on Linux)
|
||||
options:
|
||||
image:
|
||||
description:
|
||||
- The ISO image to extract files from.
|
||||
type: path
|
||||
required: true
|
||||
aliases: [ path, src ]
|
||||
dest:
|
||||
description:
|
||||
- The destination directory to extract files to.
|
||||
type: path
|
||||
required: true
|
||||
files:
|
||||
description:
|
||||
- A list of files to extract from the image.
|
||||
- Extracting directories does not work.
|
||||
type: list
|
||||
elements: str
|
||||
required: true
|
||||
force:
|
||||
description:
|
||||
- If C(true), which will replace the remote file when contents are different than the source.
|
||||
- If C(false), the file will only be extracted and copied if the destination does not already exist.
|
||||
type: bool
|
||||
default: true
|
||||
executable:
|
||||
description:
|
||||
- The path to the C(7z) executable to use for extracting files from the ISO.
|
||||
- If not provided, it will assume the value C(7z).
|
||||
type: path
|
||||
notes:
|
||||
- Only the file checksum (content) is taken into account when extracting files
|
||||
from the ISO image. If I(force=false), only checks the presence of the file.
|
||||
- In Ansible 2.3 this module was using C(mount) and C(umount) commands only,
|
||||
requiring root access. This is no longer needed with the introduction of 7zip
|
||||
for extraction.
