ansible-playbook常用模块(module) copy

先上官网文档地址:http://docs.ansible.com/ansible/copy_module.html

copy模块的坐拥其实就是 将某个文件拷贝到远程主机上,比如,我们本机有个脚本需要在远程主机执行一下,第一步肯定是拷贝过去

例子:

当然,正如官方文档上介绍,我们可以可以用copy来创建一个指定内容的文件:

这个时候我们需要将src 替换为: content

附录官网完整参数:

parameter required default choices comments
backup

no no
  • yes
  • no
Create a backup file including the timestamp information so you can get the original file back if you somehow clobbered it incorrectly.
content

no
When used instead of ‘src’, sets the contents of a file directly to the specified value. This is for simple values, for anything complex or with formatting please switch to the template module.
dest

yes
Remote absolute path where the file should be copied to. If src is a directory, this must be a directory too.
directory_mode

(added in 1.5)
no
When doing a recursive copy set the mode for the directories. If this is not set we will use the system defaults. The mode is only set on directories which are newly created, and will not affect those that already existed.
follow

(added in 1.8)
no no
  • yes
  • no
This flag indicates that filesystem links, if they exist, should be followed.
force

no yes
  • yes
  • no
the default is yes, which will replace the remote file when contents are different than the source. If no, the file will only be transferred if the destination does not exist.
aliases: thirsty

group

no
Name of the group that should own the file/directory, as would be fed to chown.
mode

no
Mode the file or directory should be. For those used to /usr/bin/chmod remember that modes are actually octal numbers (like 0644). Leaving off the leading zero will likely have unexpected results. As of version 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).
owner

no
Name of the user that should own the file/directory, as would be fed to chown.
remote_src

(added in 2.0)
no no
  • True
  • False
If False, it will search for src at originating/master machine, if True it will go to the remote/target machine for the src. Default is False.
Currently remote_src does not support recursive copying.
selevel

no s0
Level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range. _default feature works as for seuser.
serole

no
Role part of SELinux file context, _default feature works as for seuser.
setype

no
Type part of SELinux file context, _default feature works as for seuser.
seuser

no
User part of SELinux file context. Will default to system policy, if applicable. If set to_default, it will use the user portion of the policy if available.
src

no
Local path to a file to copy to the remote server; can be absolute or relative. If path is a directory, it is copied recursively. In this case, if path ends with “/”, only inside contents of that directory are copied to destination. Otherwise, if it does not end with “/”, the directory itself with all contents is copied. This behavior is similar to Rsync.
unsafe_writes

(added in 2.2)
no
Normally this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, sometimes systems are configured or just broken in ways that prevent this. One example are docker mounted files, they cannot be updated atomically and can only be done in an unsafe manner.
This boolean option allows ansible to fall back to unsafe methods of updating files for those cases in which you do not have any other choice. Be aware that this is subject to race conditions and can lead to data corruption.
validate

no None
The validation command to run before copying into place. The path to the file to validate is passed in via ‘%s’ which must be present as in the example below. The command is passed securely so shell features like expansion and pipes won’t work.
