puppet filebucket命令通常用来做文件的备份、获取和还原,支持远程操作.
puppet 节点会在每次更新之前，将该节点运行的环境配置文件以md5的形式存储到/var/lib/puppet/bucket目录,里面包含了每个配置文件的内容、路径和名称，通过filebucket命令指定文件的md5值可将指定文件恢复.

USAGE ----- puppet filebucket <mode> [-h|--help] [-V|--version] [-d|--debug] [- v |--verbose] [-l|-- local ] [-r|--remote] [-s|--server <server>] [-b|--bucket <directory>] < file > < file > ... Puppet filebucket can operate in three modes, with only one mode per call: backup: Send one or more files to the specified file bucket. Each sent file is printed with its resulting md5 sum . get: Return the text associated with an md5 sum . The text is printed to stdout, and only one file can be retrieved at a time . restore: Given a file path and an md5 sum , store the content associated with the sum into the specified file path. You can specify an entirely new path to this argument; you are not restricted to restoring the content to its original location. DESCRIPTION ----------- This is a stand-alone filebucket client for sending files to a local or central filebucket. Note that 'filebucket' defaults to using a network-based filebucket available on the server named 'puppet' . To use this, you'll have to be running as a user with valid Puppet certificates. Alternatively, you can use your local file bucket by specifying '--local' . OPTIONS ------- Note that any setting that's valid in the configuration file is also a valid long argument. For example, 'ssldir' is a valid setting, so you can specify '--ssldir <directory>' as an argument. See the configuration file documentation at http: //docs .puppetlabs.com /references/stable/configuration .html for the full list of acceptable parameters. A commented list of all configuration options can also be generated by running puppet with '--genconfig' . * --debug: #开启debug调试模式 Enable full debugging. * --help: Print this help message * -- local : #使用本地的filebucket，这将使用默认配置. Use the local filebucket. This will use the default configuration information. * --remote: #使用远程的filebucket,将使用默认配置信息. Use a remote filebucket. This will use the default configuration information. * --server: #使用服务器发送的文件而不是局部(agent)。 The server to send the file to, instead of locally. * --verbose: Print extra information. * --version: Print version information. EXAMPLE ------- $ puppet filebucket backup /etc/passwd /etc/passwd : 429b225650b912a2ee067b0a4cf1e949 $ puppet filebucket restore /tmp/passwd 429b225650b912a2ee067b0a4cf1e949 AUTHOR ------ Luke Kanies COPYRIGHT --------- Copyright (c) 2011 Puppet Labs, LLC Licensed under the Apache 2.0 License |
