salt.modules.cp

Minion side functions for salt-cp

salt.modules.cp.cache_dir(path, saltenv='base', include_empty=False, include_pat=None, exclude_pat=None, env=None)

Download and cache everything under a directory from the master

include_pat : None

Glob or regex to narrow down the files cached from the given path. If matching with a regex, the regex must be prefixed with E@, otherwise the expression will be interpreted as a glob.

2014.7.0 新版功能.

exclude_pat : None

Glob or regex to exclude certain files from being cached from the given path. If matching with a regex, the regex must be prefixed with E@, otherwise the expression will be interpreted as a glob.

注解

If used with include_pat, files matching this pattern will be excluded from the subset of files defined by include_pat.

CLI范例:

salt '*' cp.cache_dir salt://path/to/dir
salt '*' cp.cache_dir salt://path/to/dir include_pat='E@*.py$'
salt.modules.cp.cache_file(path, saltenv='base', env=None)

Used to cache a single file on the salt-minion Returns the location of the new cached file on the minion

CLI 范例:

salt '*' cp.cache_file salt://path/to/file
salt.modules.cp.cache_files(paths, saltenv='base', env=None)

Used to gather many files from the master, the gathered files will be saved in the minion cachedir reflective to the paths retrieved from the master.

CLI 范例:

salt '*' cp.cache_files salt://pathto/file1,salt://pathto/file1
salt.modules.cp.cache_local_file(path)

Cache a local file on the minion in the localfiles cache

CLI 范例:

salt '*' cp.cache_local_file /etc/hosts
salt.modules.cp.cache_master(saltenv='base', env=None)

Retrieve all of the files on the master and cache them locally

CLI 范例:

salt '*' cp.cache_master
salt.modules.cp.get_dir(path, dest, saltenv='base', template=None, gzip=None, env=None, **kwargs)

Used to recursively copy a directory from the salt master

CLI 范例:

salt '*' cp.get_dir salt://path/to/dir/ /minion/dest

get_dir supports the same template and gzip arguments as get_file.

salt.modules.cp.get_file(path, dest, saltenv='base', makedirs=False, template=None, gzip=None, env=None, **kwargs)

Used to get a single file from the salt master

CLI 范例:

salt '*' cp.get_file salt://path/to/file /minion/dest

模板渲染功能可以同时在源和目标文件启用，命名像这样：

salt '*' cp.get_file "salt://{{grains.os}}/vimrc" /etc/vimrc template=jinja

This example would instruct all Salt minions to download the vimrc from a directory with the same name as their os grain and copy it to /etc/vimrc

For larger files, the cp.get_file module also supports gzip compression. Because gzip is CPU-intensive, this should only be used in scenarios where the compression ratio is very high (e.g. pretty-printed JSON or YAML files).

Use the gzip named argument to enable it. Valid values are 1..9, where 1 is the lightest compression and 9 the heaviest. 1 uses the least CPU on the master (and minion), 9 uses the most.

salt.modules.cp.get_file_str(path, saltenv='base', env=None)

Return the contents of a file from a URL

CLI 范例:

salt '*' cp.get_file_str salt://my/file
salt.modules.cp.get_template(path, dest, template='jinja', saltenv='base', env=None, makedirs=False, **kwargs)

Render a file as a template before setting it down. Warning, order is not the same as in fileclient.cp for non breaking old API.

CLI 范例:

salt '*' cp.get_template salt://path/to/template /minion/dest
salt.modules.cp.get_url(path, dest, saltenv='base', env=None)

Used to get a single file from a URL.

The default behaviour is to write the fetched file to the given destination path. To simply return the text contents instead, set destination to None.

CLI 范例:

salt '*' cp.get_url salt://my/file /tmp/mine
salt '*' cp.get_url http://www.slashdot.org /tmp/index.html
salt.modules.cp.hash_file(path, saltenv='base', env=None)

Return the hash of a file, to get the hash of a file on the salt master file server prepend the path with salt://<file on server> otherwise, prepend the file with / for a local file.

CLI 范例:

salt '*' cp.hash_file salt://path/to/file
salt.modules.cp.is_cached(path, saltenv='base', env=None)

Return a boolean if the given path on the master has been cached on the minion

CLI 范例:

salt '*' cp.is_cached salt://path/to/file
salt.modules.cp.list_master(saltenv='base', prefix='', env=None)

List all of the files stored on the master

CLI 范例:

salt '*' cp.list_master
salt.modules.cp.list_master_dirs(saltenv='base', prefix='', env=None)

List all of the directories stored on the master

CLI 范例:

salt '*' cp.list_master_dirs

List all of the symlinks stored on the master

CLI 范例:

salt '*' cp.list_master_symlinks
salt.modules.cp.list_minion(saltenv='base', env=None)

List all of the files cached on the minion

CLI 范例:

salt '*' cp.list_minion
salt.modules.cp.list_states(saltenv='base', env=None)

List all of the available state modules in an environment

CLI 范例:

salt '*' cp.list_states
salt.modules.cp.push(path, keep_symlinks=False, upload_path=None, remove_source=False)

Push a file from the minion up to the master, the file will be saved to the salt master in the master's minion files cachedir (defaults to /var/cache/salt/master/minions/minion-id/files)

Since this feature allows a minion to push a file up to the master server it is disabled by default for security purposes. To enable, set file_recv to True in the master configuration file, and restart the master.

keep_symlinks
Keep the path value without resolving its canonical form
upload_path
Provide a different path inside the master's minion files cachedir
remove_source

Remove the source file on the minion

2016.3.0 新版功能.

CLI 范例:

salt '*' cp.push /etc/fstab
salt '*' cp.push /etc/system-release keep_symlinks=True
salt '*' cp.push /etc/fstab upload_path='/new/path/fstab'
salt '*' cp.push /tmp/filename remove_source=True
salt.modules.cp.push_dir(path, glob=None, upload_path=None)

Push a directory from the minion up to the master, the files will be saved to the salt master in the master's minion files cachedir (defaults to /var/cache/salt/master/minions/minion-id/files). It also has a glob for matching specific files using globbing.

upload_path
Provide a different path and directory name inside the master's minion files cachedir

CLI 范例:

salt '*' cp.push /usr/lib/mysql
salt '*' cp.push /usr/lib/mysql upload_path='/newmysql/path'
salt '*' cp.push_dir /etc/modprobe.d/ glob='*.conf'
salt.modules.cp.recv(files, dest)

Used with salt-cp, pass the files dict, and the destination.

This function receives small fast copy files from the master via salt-cp. It does not work via the CLI.
