This article is to share with you the kubernetes cluster deployment tutorial, I believe most people do not know how to deploy, in order to let you learn, so to sum up the following content. The most basic hardware requirements

CPU: dual core

MEm:2G

3 dockerhost time must be synchronized

Kubeadm tool

All three are in operation:

1. Name:

[root@docker01 ~] # hostnamectl set-hostname master

[root@docker02 ~] # hostnamectl set-hostname node02

[root@docker03 ~] # hostnamectl set-hostname node03

1.

All 3 validate docker: (the version must be the same)

two。

[root@master] # docker-v

Docker version 18.09.0, build 4d60db4

1.

3 docker disable swap.

two。

[root@master ~] # swapoff-a # # temporarily disabled

[root@master] # free-h

Total used free shared buff/cache available

Mem: 1.8G 521M 193M 18M 1.1G 1.0G

Swap: 0B 0B 0B

[root@master ~] # vim / etc/fstab

11 lines: # / dev/mapper/cl-swap swap

Add domain name resolution:

[root@master ~] # vim / etc/hosts

192.168.1.10 master

192.168.1.20 node02

192.168.1.30 node03

Master:

Secret-free login:

[root@master] # ssh-keygen-t rsa

[root@master ~] # ssh-copy-id node02

[root@master ~] # ssh-copy-id node03

[root@master ~] # vim / etc/sysctl.d/k8s.conf # enable iptables bridging function

Net.bridge.bridge-nf-call-iptables = 1

Net.bridge.bridge-nf-call-ip6tables = 1

Route forwarding:

[root@master ~] # echo net.ipv4.ip_forward = 1 > > / etc/sysctl.conf

[root@master] # sysctl-p

[root@master] # sysctl-p / etc/sysctl.d/k8s.conf

The following conditions were not successfully entered:

[root@master ~] # modprobe br_netfilter

[root@master ~] # scp / etc/sysctl.d/k8s.conf node02:/etc/sysctl.d/

[root@master ~] # scp / etc/sysctl.d/k8s.conf node03:/etc/sysctl.d/

[root@master ~] # scp / etc/sysctl.conf node02:/etc/

[root@master ~] # scp / etc/sysctl.conf node03:/etc/

All three:

Add yum Feed

Cat / .bashrc

The above is the deployment of the kubernetes cluster, although the length is very complex, but the sample code is very detailed and easy to understand, if you want to learn more about it, please pay attention to the industry information.
