saltstack 从minion传送文件到master及minion文件后端minionfs系统-白红宇

演示如下:

vagrant@saltminion1:/tmp$ touch talen.txt

vagrant@saltminion1:/tmp$ echo This is a test . > talen.txt

vagrant@saltmaster:/var/cache/salt/master$ sudo salt '*' test.ping

minion2:

True

minion1:

True

vagrant@saltmaster:/var/cache/salt/master$ sudo salt '*' cp.push /tmp/talen.txt

minion2:

False

minion1:

True

vagrant@saltmaster:/var/cache/salt/master$ cd /var/cache/salt/master/minions/minion

minion1/ minion2/

vagrant@saltmaster:/var/cache/salt/master/minions$ tree

├── minion1

│ ├── files

│ │ └── tmp

│ │ └── talen.txt

│ └── mine.p

└── minion2

└── mine.p

4 directories, 3 files

有时,我们需要传送在minion上产生的文件.

salt已经有从minion上传送文件到master的特性.默认因为安全性问题,没有启用.

修改master启用这个特性.

file_recv: True

vagrant@saltmaster:~ $ vim /etc/salt/master

# Allow minions to push files to the master. This is disabled by default, for

# security purposes.

#file_recv: False

file_recv: True

salt-cp cp模块是minion端的,其它函数功能参考

# File Server Backend

#文件服务后端

# Salt supports a modular fileserver backend system, this system allows

# the salt master to link directly to third party systems to gather and

# manage the files available to minions. Multiple backends can be

# configured and will be searched for the requested file in the order in which

# they are defined here. The default setting only enables the standard backend

# "roots" which uses the "file_roots" option.

#salt支持一个模块化的文件服务后端系统,这个系统允许master直接链接到第三方平台系统收集和管理minions上的文件.请求文件将按定义的多个后端的顺序查询.默认使用file_roots选项只启用了最基本的roots.

#fileserver_backend:

# - roots

# To use multiple backends list them in the order they are searched:

#fileserver_backend:

# - git

# - roots

#按顺序列出要查询的后端列表.

#如果你想让file_server允许追踪软链接文件系统树,取消下面的注释.默认是开启的,当前默认只应用于默认的文件服务后端.

# Uncomment the line below if you do not want the file_server to follow

# symlinks when walking the filesystem tree. This is set to True

# by default. Currently this only applies to the default roots

# fileserver_backend.

#fileserver_followsymlinks: False

# Uncomment the line below if you do not want symlinks to be

# treated as the files they are pointing to. By default this is set to

# False. By uncommenting the line below, any detected symlink while listing

# files on the Master will not be returned to the Minion.

#fileserver_ignoresymlinks: True

# By default, the Salt fileserver recurses fully into all defined environments

# to attempt to find files. To limit this behavior so that the fileserver only

# traverses directories with SLS files and special Salt directories like _modules,

# enable the option below. This might be useful for installations where a file root

# has a very large number of files and performance is impacted. Default is False.

# fileserver_limit_traversal: False

# The fileserver can fire events off every time the fileserver is updated,

# these are disabled by default, but can be easily turned on by setting this

# flag to True

#fileserver_events: False

如果想使用minion上的文件系统,简单启用两个参数

fileserver_backend:

- roots

- minion

file_recv: True

从下面的执行可以看到,当我们从minion1服务器上传文件到master后,minion1的上传目录/tmp已经可以在其它minions上看到了.

其它minions可以从minion1上共享的目录下载文件.
