salt.modules.pip¶

Install Python packages with pip to either the system or a virtualenv

Windows Support¶

2014.7.4 新版功能.

Salt now uses a portable python. As a result the entire pip module is now functional on the salt installation itself. You can pip install dependencies for your custom modules. You can even upgrade salt itself using pip. For this to work properly, you must specify the Current Working Directory (cwd) and the Pip Binary (bin_env) salt should use. The variable pip_bin can be either a virtualenv path or the path to the pip binary itself.

For example, the following command will list all software installed using pip to your current salt environment:

salt <minion> pip.list cwd='C:\salt\bin\Scripts' bin_env='C:\salt\bin\Scripts\pip.exe'

Specifying the cwd and bin_env options ensures you're modifying the salt environment. If these are omitted, it will default to the local installation of python. If python is not installed locally it will fail saying it couldn't find pip.

State File Support¶

This functionality works in states as well. If you need to pip install colorama with a state, for example, the following will work:

install_colorama:
  pip.installed:
    - name: colorama
    - cwd: 'C:\salt\bin\scripts'
    - bin_env: 'C:\salt\bin\scripts\pip.exe'
    - upgrade: True

Upgrading Salt using Pip¶

You can now update salt using pip to any version from the 2014.7 branch forward. Previous version require recompiling some of the dependencies which is painful in windows.

To do this you just use pip with git to update to the version you want and then restart the service. Here is a sample state file that upgrades salt to the head of the 2015.5 branch:

install_salt:
  pip.installed:
    - cwd: 'C:\salt\bin\scripts'
    - bin_env: 'C:\salt\bin\scripts\pip.exe'
    - editable: git+https://github.com/saltstack/salt@2015.5#egg=salt
    - upgrade: True

restart_service:
  service.running:
    - name: salt-minion
    - enable: True
    - watch:
      - pip: install_salt

注解

If you're having problems, you might try doubling the back slashes. For example, cwd: 'C:\salt\bin\scripts'. Sometimes python thinks the single back slash is an escape character.

salt.modules.pip.freeze(bin_env=None, user=None, cwd=None, use_vt=False)¶

Return a list of installed packages either globally or in the specified virtualenv

bin_env: path to pip bin or path to virtualenv. If doing an uninstall from the system python and want to use a specific pip bin (pip-2.7, pip-2.6, etc..) just specify the pip bin you want. If uninstalling from a virtualenv, just use the path to the virtualenv (/home/code/path/to/virtualenv/)
user: The user under which to run pip
cwd: Current working directory to run pip from

CLI 范例:

salt '*' pip.freeze /home/code/path/to/virtualenv/

Install packages with pip

Install packages individually or from a pip requirements file. Install packages globally or to a virtualenv.

pkgs

Comma separated list of packages to install

requirements

Path to requirements

bin_env

Path to pip bin or path to virtualenv. If doing a system install, and want to use a specific pip bin (pip-2.7, pip-2.6, etc..) just specify the pip bin you want.

no_use_wheel

Force to not use wheel archives (requires pip>=1.4)

log

Log file where a complete (maximum verbosity) record will be kept

proxy

Specify a proxy in the form user:passwd@proxy.server:port. Note that the user:password@ is optional and required only if you are behind an authenticated proxy. If you provide user@proxy.server:port then you will be prompted for a password.

timeout

Set the socket timeout (default 15 seconds)

editable

install something editable (e.g. git+https://github.com/worldcompany/djangoembed.git#egg=djangoembed)

find_links

URL to search for packages

index_url

Base URL of Python Package Index

extra_index_url

Extra URLs of package indexes to use in addition to index_url

no_index

mirrors

Specific mirror URL(s) to query (automatically adds --use-mirrors)

build

Unpack packages into build dir

target

no_download

Don't download any packages, just install the ones already downloaded (completes an install run with --no-install)

install_options

Extra arguments to be supplied to the setup.py install command (e.g. like --install-option='--install-scripts=/usr/local/bin'). Use multiple --install-option options to pass multiple options to setup.py install. If you are using an option with a directory path, be sure to use absolute path.

global_options

Extra global options to be supplied to the setup.py call before the install command.

user

The user under which to run pip

no_chown

When user is given, do not attempt to copy and chown a requirements file

cwd

Current working directory to run pip from

activate

Activates the virtual environment, if given via bin_env, before running install.

2014.7.2 版后已移除: If bin_env is given, pip will already be sourced from that virtualenv, making activate effectively a noop.

trusted_host

Mark this host as trusted, even though it does not have valid or any HTTPS.
