About this matter , Finally, it's over . If you start from installation , It took about twenty hours , It's a long job . If we do it from the beginning , That's really too long .

During this installation , I am right. kubernetes With a deeper understanding , I don't think it's too much to take this thing as a task .

Of course , Understanding is still relatively shallow , I don't agree that the information I found is shallow , I was too radical during this period of time , I haven't eaten well , Just arrive “ I see ”, Then the next part, It is impossible for me to retell .

But now I'm done deploying , I look back , There is still a month for me to slowly understand 、 Digestion 、 expansion .

I admit that this deployment has “ bet ” The ingredients are in it , not so bad , I bet right . I began to write the first article “ Environmental preparation ” When , In fact, I have only done docker Install over there , That is to say master The previous step of installation .

But at that time, I really didn't know where the certificate went wrong , First, I don't know about these certificates , stay “ Preparation for the new term ” That article said , I'm going to sort out the certificate after I've written it all . So I stopped , Go through all the certificates . then , Restart deployment .

Here I want to remind myself , Want a full uninstall k8s Clustered . The reason why the deployment was restarted , This is because the previously deployed cluster will not be cleaned up , As a result, only two virtual machines can be reopened .

I suggest having the ability 、 Have an idea 、 A willing friend , You can experience , If you want to go Architecture , You have to do these things sooner or later .

No more nonsense , Let me sort out the blog in this process ：
