salt.modules.genesis¶

Module for managing container and VM images

salt.modules.genesis.avail_platforms()¶

Return which platforms are available

命令行接口CLI 范例:

salt myminion genesis.avail_platforms

salt.modules.genesis.bootstrap(platform, root, img_format='dir', fs_format='ext2', fs_opts=None, arch=None, flavor=None, repo_url=None, static_qemu=None, img_size=None, mount_dir=None, pkg_cache=None, pkgs=None, exclude_pkgs=None, epel_url='http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm')¶

Create an image for a specific platform.

Please note that this function MUST be run as root, as images that are created make files belonging to root.

platform

Which platform to use to create the image. Currently supported platforms are rpm, deb and pacman.

root

Local path to create the root of the image filesystem.

img_format

Which format to create the image in. By default, just copies files into a directory on the local filesystem (dir). Future support will exist for sparse.

fs_format

When using a non-dir img_format, which filesystem to format the image to. By default, ext2.

fs_opts

When using a non-dir img_format, a dict of opts may be specified.

arch

Architecture to install packages for, if supported by the underlying bootstrap tool. Currently only used for deb.

flavor

Which flavor of operating system to install. This correlates to a specific directory on the distribution repositories. For instance, wheezy on Debian.

repo_url

Mainly important for Debian-based repos. Base URL for the mirror to install from. (e.x.: http://ftp.debian.org/debian/)

static_qemu

Local path to the static qemu binary required for this arch. (e.x.: /usr/bin/qemu-amd64-static)

pkg_confs

The location of the conf files to copy into the image, to point the installer to the right repos and configuration.

img_size

If img_format is not dir, then the size of the image must be specified.

mount_dir

If img_format is not dir, then the image must be mounted somewhere. If the mount_dir is not specified, then it will be created at /opt/salt-genesis.<random_uuid>. This directory will be unmounted and removed when the process is finished.

pkg_cache

This points to a directory containing a cache of package files to be copied to the image. It does not need to be specified.

pkgs

A list of packages to be installed on this image. For RedHat, this will include yum, centos-release and iputils by default.

exclude_pkgs

A list of packages to be excluded. If you do not want to install the defaults, you need to include them in this list.

epel_url

The URL to download the EPEL release package from.

CLI范例:

salt myminion genesis.bootstrap pacman /root/arch
salt myminion genesis.bootstrap rpm /root/redhat
salt myminion genesis.bootstrap deb /root/wheezy arch=amd64             flavor=wheezy static_qemu=/usr/bin/qemu-x86_64-static

salt.modules.genesis.ldd_deps(filename, ret=None)¶

Recurse through a set of dependencies reported by ldd, to find associated dependencies.

Please note that this does not necessarily resolve all (non-package) dependencies for a file; but it does help.

命令行接口CLI 范例:

salt myminion genesis.ldd_deps bash salt myminion genesis.ldd_deps /bin/bash

salt.modules.genesis.mksls(fmt, src, dst=None)¶

Convert an installation file/script to an SLS file. Currently supports kickstart, preseed, and autoyast.

CLI范例:

salt <minion> genesis.mksls kickstart /path/to/kickstart.cfg salt <minion> genesis.mksls kickstart /path/to/kickstart.cfg /path/to/dest.sls

Beryllium 新版功能.

salt.modules.genesis.pack(name, root, path=None, pack_format='tar', compress='bzip2')¶

Pack up a directory structure, into a specific format

CLI范例:

salt myminion genesis.pack centos /root/centos
salt myminion genesis.pack centos /root/centos pack_format='tar'

salt.modules.genesis.unpack(name, dest=None, path=None, pack_format='tar', compress='bz2')¶

Unpack an image into a directory structure

命令行接口CLI 范例:

salt myminion genesis.unpack centos /root/centos
