為什麼 使用 Proxmox VE?

為什麼 要做虛擬機練習系統?
Photo by Christina @ wocintechchat.com on Unsplash 熟悉 DevOps 的人太少
Photo by Jordan Sanchez on Unsplash 練習的機會不多
Photo by Christian Fregnan on Unsplash 人工開設虛擬機並不方便
如何用 Proxmox VE 解決 問題?
API Snapshot Qemu Agent + +
require 'net/http' rquire 'oj' uri = URI('https:!//192.168.100.220:8006/api2/json/access/ticket') req = Net!::HTTP!::Post.new
req['Content-Type'] = 'application/x-!!www-form-urlencoded' req.body = URI.encode_!!www_form(username: 'xxx@pve', password: 'xxx') token = {} Net!::HTTP.start(uri.host, uri.port, use_ssl: true) do |http| res = http.request(req) token = Oj.load(res.body)&.fetch('data', {}) end puts token['ticket'] # !=> XXXX puts token['CSRFPreventionToken'] # !=> XXX
require 'net/http' rquire 'oj' uri = URI(TICKET_URI) req = Net!::HTTP!::Post.new
req['Content-Type'] = 'application/x-!!www-form-urlencoded' req.body = URI.encode_!!www_form( username: 'xxx@pve', password: 'xxx' )
token = {} Net!::HTTP.start( uri.host, uri.port, use_ssl: true ) do
|http| res = http.request(req) token = Oj.load(res.body)&.fetch('data', {}) end puts token['ticket'] # !=> XXXX puts token['CSRFPreventionToken'] # !=> XXX
req = Net!::HTTP!::Get.new(uri) req['Cookie'] = "PVEAuthCookie=!#{token['ticket']}"
req = Net!::HTTP!::Post.new(uri) req['Cookie'] = "PVEAuthCookie=!#{token['ticket']}" req['CSRFPreventionToken'] = token['CSRFPreventionToken']
詳細的文件可以在 Wiki 中找到
非同步 行為處理
Proxmox!::API.post('nodes/pve/100/status/start') .fetch(:data) # !=> UPID:pve:00001560:3C9C598C:5C6944F7:qmstart: 100:user@pve:
需要自己用 UPID 確認狀態
loop do status = task('pve', upid) break if status['exitstatus'] !==
'OK' sleep 1 end
