容器云平台搭建步骤详情：

k8s

1.虚拟机配置信息：

Master：内存6G + 处理器 2*2 + 硬盘160G + 网卡1(192.168.200.103)

Node：内存6G + 处理器 2*2 + 硬盘160G + 网卡1(192.168.200.104)

2.基础环境：

2.1 关闭防火墙+关闭selinux+设置主机名+编写hosts文件

Master：
[root@localhost ~]# hostnamectl set-hostname master
[root@localhost ~]# bash


[root@master ~]# vim /etc/hosts 
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.103 master
192.168.200.104 node
[root@master ~]# scp /etc/hosts node:/etc/hosts


[root@master ~]# systemctl stop firewalld
[root@master ~]# systemctl disable firewalld
[root@master ~]# iptables -F



[root@master ~]# swapoff -a 
[root@master ~]# sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
[root@master ~]# setenforce 0
[root@master ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config 



Node:
[root@localhost ~]# hostnamectl set-hostname node
[root@localhost ~]# bash


[root@node ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.103 master
192.168.200.104 node


[root@node ~]# swapoff -a 
[root@node ~]# sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
[root@node ~]# setenforce 0
[root@node ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config 


[root@node ~]# iptables -F
[root@node ~]# systemctl stop firewalld
[root@node ~]# systemctl disable firewalld

2.2导入镜像+挂载镜像+copy镜像

[root@master ~]# ls
CentOS-7-x86_64-DVD-1804.iso  chinaskills_cloud_paas.iso
[root@master ~]# mkdir /opt/centos


[root@master ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /opt/centos


[root@master ~]# mount -o loop chinaskills_cloud_paas.iso /mnt /
mount: /dev/loop0 is write-protected, mounting read-only
[root@master ~]# cp -r /mnt/* /opt/
[root@master ~]# umount /mnt/

3.3配置yum源

Master:
[root@master ~]# rm -rf /etc/yum.repos.d/*
[root@master ~]# vim /etc/yum.repos.d/local.repo 
[centos]
name=centos
gpgcheck=0
enabled=1
baseurl=file:///opt/centos
[k8s]
name=k8s
gpgcheck=0
enabled=1
baseurl=file:///opt/kubernetes-repo



Node:
[root@node ~]# rm -rf /etc/yum.repos.d/*
[root@node ~]# vim /etc/yum.repos.d/local.repo 
[centos]
name=centos
gpgcheck=0
enabled=1
baseurl=ftp://master/centos
[k8s]
name=k8s
gpgcheck=0
enabled=1
baseurl=ftp://master/kubernetes-repo

3.执行脚本顺序：

Master:
[root@master opt]# cd /opt/
[root@master opt]# ./k8s_harbor_install.sh


[root@master opt]# ./k8s_image_push.sh 
输入镜像仓库地址(不加http/https): 192.168.200.103
输入镜像仓库用户名: admin
输入镜像仓库用户密码: Harbor12345
您设置的仓库地址为: 192.168.200.103,用户名: admin,密码: xxx
是否确认(Y/N): y


[root@master opt]# ./k8s_master_install.sh 
[root@master opt]# scp /opt/k8s_node_install.sh node:/opt/


Node:
[root@node ~]# cd /opt/
[root@node opt]# ./k8s_node_install.sh
输入镜像仓库地址(不加http/https): 192.168.200.103
输入镜像仓库用户名: admin
输入镜像仓库用户密码: Harbor12345
您设置的仓库地址为: 192.168.200.103,用户名: admin,密码: xxx
是否确认(Y/N): y

4.验证：

4.1查看私有仓库：

浏览器通过http://192.168.200.103访问Harbor
此处推荐使用火狐浏览器
私有仓库

4.2 查看集群状态：

[root@master ~]# kubectl get node
NAME     STATUS   ROLES    AGE     VERSION
master   Ready    master   6m25s   v1.18.1
node     Ready    <none>   2m32s   v1.18.1

[root@master ~]# kubectl get pod -n kube-system

kube-proxy-qx76c                 1/1     Running   0          6m52s
kube-proxy-tnvkg                 1/1     Running   0          3m18s
kube-scheduler-master            1/1     Running   0          7m2s

4.3 访问dashboard界面：

执行完 k8s_master_install.sh 最后出现如下字样

dashboard地址：https://192.168.200.103:30000
