module: unarchive
version_added: '1.4'
short_description: Unpacks an archive after (optionally) copying it from the local machine
description:
- The C(unarchive) module unpacks an archive. It will not unpack a compressed file that does not contain an archive.
- By default, it will copy the source file from the local system to the target before unpacking.
- Set C(remote_src=yes) to unpack an archive which already exists on the target.
- If checksum validation is desired, use M(ansible.builtin.get_url) or M(ansible.builtin.uri) instead to fetch the file and set C(remote_src=yes).
- For Windows targets, use the M(community.windows.win_unzip) module instead.
options:
src:
description:
- If C(remote_src=no) (default), local path to archive file to copy to the target server; can be absolute or relative. If C(remote_src=yes), path on the
target server to existing archive file to unpack.
- If C(remote_src=yes) and C(src) contains C(://), the remote machine will download the file from the URL first. (version_added 2.0). This is only for
simple cases, for full download support use the M(ansible.builtin.get_url) module.
type: path
required: true
dest:
description:
- Remote absolute path where the archive should be unpacked.
- The given path must exist. Base directory is not created by this module.
type: path
required: true
copy:
description:
- If true, the file is copied from local controller to the managed (remote) node, otherwise, the plugin will look for src archive on the managed machine.
- This option has been deprecated in favor of C(remote_src).
- This option is mutually exclusive with C(remote_src).
type: bool
default: yes
creates:
description:
- If the specified absolute path (file or directory) already exists, this step will B(not) be run.
- The specified absolute path (file or directory) must be below the base path given with C(dest:).
type: path
version_added: "1.6"
io_buffer_size:
description:
- Size of the volatile memory buffer that is used for extracting files from the archive in bytes.
type: int
default: 65536
version_added: "2.12"
list_files:
description:
- If set to True, return the list of files that are contained in the tarball.
type: bool
default: no
version_added: "2.0"
exclude:
description:
- List the directory and file entries that you would like to exclude from the unarchive action.
- Mutually exclusive with C(include).
type: list
default: []
elements: str
version_added: "2.1"
include:
description:
- List of directory and file entries that you would like to extract from the archive. If C(include)
is not empty, only files listed here will be extracted.
- Mutually exclusive with C(exclude).
type: list
default: []
elements: str
version_added: "2.11"
keep_newer:
description:
- Do not replace existing files that are newer than files from the archive.
type: bool
default: no
version_added: "2.1"
extra_opts:
description:
- Specify additional options by passing in an array.
- Each space-separated command-line option should be a new element of the array. See examples.
- Command-line options with multiple elements must use multiple lines in the array, one for each element.
type: list
elements: str
default: []
version_added: "2.1"
remote_src:
description:
- Set to C(true) to indicate the archived file is already on the remote system and not local to the Ansible controller.
- This option is mutually exclusive with C(copy).
type: bool
default: no
version_added: "2.2"
validate_certs:
description:
- This only applies if using a https URL as the source of the file.
- This should only set to C(false) used on personally controlled sites using self-signed certificate.
- Prior to 2.2 the code worked as if this was set to C(true).
type: bool
default: yes
version_added: "2.2"
extends_documentation_fragment:
- action_common_attributes
- action_common_attributes.flow

attributes:
action:
support: full
async:
support: none
bypass_host_loop:
support: none
check_mode:
support: partial
details: Not supported for gzipped tar files.
diff_mode:
support: partial
details: Uses gtar's C(--diff) arg to calculate if changed or not. If this C(arg) is not supported, it will always unpack the archive.
platform:
platforms: posix
safe_file_operations:
support: none
vault:
support: full
todo:
- Re-implement tar support using native tarfile module.
- Re-implement zip support using native zipfile module.
notes:
- Requires C(zipinfo) and C(gtar)/C(unzip) command on target host.
- Requires C(zstd) command on target host to expand I(.tar.zst) files.
- Can handle I(.zip) files using C(unzip) as well as I(.tar), I(.tar.gz), I(.tar.bz2), I(.tar.xz), and I(.tar.zst) files using C(gtar).
- Does not handle I(.gz) files, I(.bz2) files, I(.xz), or I(.zst) files that do not contain a I(.tar) archive.
- Existing files/directories in the destination which are not in the archive
are not touched. This is the same behavior as a normal archive extraction.
- Existing files/directories in the destination which are not in the archive
are ignored for purposes of deciding if the archive should be unpacked or not.
