module: archive
short_description: Creates a compressed archive of one or more files or trees
extends_documentation_fragment: files
description:
- Creates or extends an archive.
- The source and archive are on the remote host, and the archive I(is not) copied to the local host.
- Source files can be deleted after archival by specifying I(remove=True).
options:
path:
description:
- Remote absolute path, glob, or list of paths or globs for the file or files to compress or archive.
type: list
required: true
format:
description:
- The type of compression to use.
- Support for xz was added in Ansible 2.5.
type: str
choices: [ bz2, gz, tar, xz, zip ]
default: gz
dest:
description:
- The file name of the destination archive. The parent directory must exists on the remote host.
- This is required when C(path) refers to multiple files by either specifying a glob, a directory or multiple paths in a list.
type: path
exclude_path:
description:
- Remote absolute path, glob, or list of paths or globs for the file or files to exclude from the archive.
type: list
force_archive:
description:
- Allow you to force the module to treat this as an archive even if only a single file is specified.
- By default behaviour is maintained. i.e A when a single file is specified it is compressed only (not archived).
type: bool
default: false
remove:
description:
- Remove any added source files and trees after adding to archive.
type: bool
default: no
notes:
- Requires tarfile, zipfile, gzip and bzip2 packages on target host.
- Requires lzma or backports.lzma if using xz format.
- Can produce I(gzip), I(bzip2), I(lzma) and I(zip) compressed files or archives.
