Kubeadm初始化Kubernetes叢集
阿新 • • 發佈：2019-01-08
不得不說的話：2019年1月4日，註定讓我難忘，也註定要改變些什麼！我所做的事只是為了在2019年的7月份可以找到一份工作，不至於我畢業就失業了。我愛運維嗎？不愛！為什麼一直在這條路上，無非是上了賊船還由得我選嗎？
今天早上9點不到就開始了學習：Kubeadm初始化Kubernetes叢集 我看到過前輩們在這塊知識點上費了很多時間，所以我做好了用一天的時間來完成這塊知識點。視訊時間1小時24分整。我目前知道的是有三種方法可以部署kubernetes叢集，前輩也和我建議過用二進位制部署的方法即符合公司要求也可以少踩很多坑。可我想既然視訊買了，書也買了，總不能不學一下吧，於是我決定先跟視訊和書走一遍再二進位制部署一遍再ansible部署一遍。事實證明，真的踩了許多坑，踩坑是高興的，因為我做好了準備
中午想去吃飯，可看到錯誤還在那裡，怎麼也邁不動腿，隨性坐下繼續排錯。今天啊從早上9點不到到下午17點52分，上了一趟廁所，其餘的時間都在部署。終於成功了，心中很是開心。下面的路還有太多未知的坑，我願意一個一個的來踩。
下面給出我在本次部署中的所有程式碼，不是懶得整理，我放出來只是想告訴我自己，這就是我今天所做的一切！！！
