puppet 4.4 之前的版本不支持http方式同步文件

snippet.puppet

  define remote_file($remote_location=undef, $mode='0644', $service=undef, $md5=undef){
    exec{ "retrieve_${title}":
    unless => "/usr/bin/md5sum ${title} |/usr/bin/grep -w ${md5}",
    command => "/usr/bin/curl -s ${remote_location} --create-dirs -o /tmp${title} && /usr/bin/md5sum /tmp${title} |/usr/bin/grep -w ${md5} && /usr/bin/mv -f ${title} /tmp && /usr/bin/mv -f /tmp${title} ${title} || exit 1",
    #creates => $title,
    }
 
    file{$title:
    mode    => $mode,
    require => Exec["retrieve_${title}"],
    notify => Service["$service"]
    }
  }

调用示例

snippet.puppet

remote_file {
  '/usr/local/bin/kube-proxy':
    mode => '0755',
    service => 'kube-proxy',
    md5 => '7f88a9057292971b10ad6de794f9ba62',
    remote_location => 'http://yum.intra.xxx.cn/soft/k8s/kube-proxy'
}

snippet.bash

    command => "/usr/bin/curl -s ${remote_location} --create-dirs -o /tmp${title} && /usr/bin/md5sum /tmp${title} |/usr/bin/grep -w ${md5} && /usr/bin/mv -f ${title} /tmp && /usr/bin/mv -f /tmp${title} ${title} || exit 1",
    #creates => $title,
    }
 
    file{$title:
    mode    => $mode,
    require => Exec["retrieve_${title}"],
    notify => Service["$service"]
    }
  }
}
