通过docker为容器引擎部署k8s集群环境(含harbor镜像仓库)

一.虚拟机准备

主机（我的主机名）IPmaster(node1-190.com)192.168.2.190node1(node2-191.com)192.168.2.191node2(node3-192.com)192.168.2.192node3(node4-193.com)192.168.2.193
register(node5-196.com)
192.168.2.196

二.基础环境配置（各个节点都做）

1.IP和hosts解析

[root@node1-190 ~]# vim /etc/hosts
192.168.2.190 node1-190.com
192.168.2.191 node2-191.com
192.168.2.192 node3-192.com
192.168.2.193 node4-193.com
192.168.2.196 node5-196.com

2.防火墙和selinux

[root@node1-190 ~]# systemctl status firewalld.service;getenforce 
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
Disabled
#临时
systemctl stop firewalld
setenforce 0
#禁用
systemctl disable firewalld
sed -i '/^SELINUX=/ c SELINUX=disabled' /etc/selinux/config

3.安装基本软件

[root@node1-190 ~]# yum install -y wget tree bash-completion lrzsz psmisc net-tools vim chrony

4.配置时间同步

[root@node1-190 ~]# vim /etc/chrony.conf
:3,6 s/^/#      #注释掉原有行
server ntp1.aliyun.com iburst
[root@node1-190 ~]# systemctl restart chronyd
[root@node1-190 ~]# chronyc sources
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^* 120.25.115.20                 2   8   341   431   -357us[ -771us] +/-   20ms

5.禁用swap分区

[root@node1-190 ~]# swapoff -a && sed -i 's/.*swap.*/#&/' /etc/fstab && free -m
              total        used        free      shared  buff/cache   available
Mem:          10376         943        8875          11         557        9178
Swap:             0           0           0

6.修改内核参数并重载

[root@node1-190 ~]# cat >> /etc/sysctl.conf << EOF
 vm.swappiness=0
 net.bridge.bridge-nf-call-ip6tables = 1
 net.bridge.bridge-nf-call-iptables = 1
 net.ipv4.ip_forward = 1
 EOF
[root@node1-190 ~]# modprobe br_netfilter &&  modprobe overlay && sysctl -p 
vm.swappiness = 0
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1

7.配置ipvs

[root@node1-190 ~]# yum install ipset ipvsadm -y
[root@node1-190 ~]# cat <<EOF>  /etc/sysconfig/modules/ipvs.modules
#!/bin/bash
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack
EOF
[root@node1-190 ~]# chmod +x /etc/sysconfig/modules/ipvs.modules && /bin/bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep -e ip_vs -e nf_conntrack_ipv4
nf_conntrack_ipv4      15053  2 
nf_defrag_ipv4         12729  1 nf_conntrack_ipv4
ip_vs_sh               12688  0 
ip_vs_wrr              12697  0 
ip_vs_rr               12600  0 
ip_vs                 145458  6 ip_vs_rr,ip_vs_sh,ip_vs_wrr
nf_conntrack          139264  7 ip_vs,nf_nat,nf_nat_ipv4,xt_conntrack,nf_nat_masquerade_ipv4,nf_conntrack_netlink,nf_conntrack_ipv4
libcrc32c              12644  4 xfs,ip_vs,nf_nat,nf_conntrack

三.docker环境（各个节点都做）

1.配置软件源并安装docker-ce

[root@node1-190 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@node1-190 ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@node1-190 ~]# yum install -y docker-ce

2.配置docker加速

截止2024年6月1日，dokcer-hub无法访问，目前我个人是通过阿里云的云服务器提供的镜像加速器拉取镜像

#自建harbor仓库情况
[root@node1-190 ~]# cat <<EOF> /etc/docker/daemon.json 
{
 "registry-mirrors": [
 "http://74f21445.m.daocloud.io",
 "https://registry.docker-cn.com",
 "http://hub-mirror.c.163.com",
 "https://docker.mirrors.ustc.edu.cn" ], 
 "insecure-registries": ["node5-196.com"],    #写register的域名，各个节点都写register的域名，不建harbor则不用这一行
 "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF
#没有自建仓库
[root@node1-190 ~]# cat <<EOF> /etc/docker/daemon.json 
{
 "registry-mirrors": [
 "http://74f21445.m.daocloud.io",
 "https://registry.docker-cn.com",
 "http://hub-mirror.c.163.com",
 "https://docker.mirrors.ustc.edu.cn" ], 
 "exec-opts": ["native.cgroupdriver=systemd"]
}
EOF
[root@node1-190 ~]# systemctl daemon-reload && systemctl start docker

四.cri环境配置（各个节点都做）

1.下载查看版本

http://be18.cn/cri-dockerd-0.3.4.amd64.tgz

[root@node1-190 ~]# tar -xf cri-dockerd-0.3.4.amd64.tgz -C /usr/local/
[root@node1-190 local]# ll
total 0
drwxr-xr-x. 2 root    root     6 Apr 11  2018 bin
drwxrwxr-x  2 sulibao sulibao 25 Jun 30 03:31 cri-dockerd

drwxr-xr-x. 2 root    root     6 Apr 11  2018 src
[root@node1-190 local]# mv cri-dockerd/cri-dockerd /usr/local/bin/
[root@node1-190 local]# cri-dockerd --version
cri-dockerd 0.3.4 (e88b1605)

2.配置服务启动

配置cri-dockerd.service

[root@node1-190 local]# vim /etc/systemd/system/cri-dockerd.service
[Unit]
Description=CRI Interface for Docker Application Container Engine
Documentation=https://docs.mirantis.com
After=network-online.target firewalld.service docker.service

KillMode=process
[Install]
WantedBy=multi-user.target

配置cri-dockerd.sock

[root@node1-190 local]# vim /etc/systemd/system/cri-dockerd.socket
[Unit]
Description=CRI Docker Socket for the API
PartOf=cri-docker.service
[Socket]
ListenStream=/var/run/cri-dockerd.sock

SocketUser=root
SocketGroup=docker
[Install]
WantedBy=sockets.target
[root@node1-190 ~]# systemctl daemon-reload
[root@node1-190 ~]# systemctl start cri-dockerd.service
[root@node1-190 ~]# systemctl enable cri-dockerd.service

五.harbor环境（只有做harbor的节点做，不要harbor则不做）

1.安装harbor配置

[root@node5-196 ~]# mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose
[root@node5-196 ~]# chmod +x /usr/local/bin/docker-compose 
[root@node5-196 ~]# tar -xf harbor-offline-installer-v2.8.4.tgz -C /usr/local/
[root@node5-196 ~]# cd /usr/local/
[root@node5-196 local]# ll
[root@node5-196 local]# cd harbor/
[root@node5-196 harbor]# ll

六.集群初始化

1.下载k8s所需软件（各个节点都做）

[root@node4-193 ~]#  cat << EOF> /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg 
https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
[root@node4-193 ~]# yum install kubeadm kubectl kubelet -y
[root@node1-190 ~]# systemctl start kubelet

2.拉取所需镜像（各个节点做）

（1）有自建harbor情况

[root@node1-190 ~]# vim dockerimages.sh 
#!/bin/bash
images=$(kubeadm config images list --kubernetes-version=1.28.2 | awk -F '/' '{print $NF}')
for i in ${images}
do
  docker pull registry.aliyuncs.com/google_containers/$i
  docker tag registry.aliyuncs.com/google_containers/$i node5-196.com/google_containers/$i    #需要修改为刚创建的harbor的仓库地址
  docker push node5-196.com/google_containers/$i
  docker rmi registry.aliyuncs.com/google_containers/$i
done
[root@node1-190 ~]# docker login node5-196.com
Username: admin 
Password:

[root@node1-190 ~]# bash dockerimages.sh
[root@node1-190 ~]# docker images
REPOSITORY                                                TAG       IMAGE ID       CREATED         SIZE
node5-196.com/google_containers/kube-apiserver            v1.28.2   bb5e0dde9054   2 weeks ago     126MB

node5-196.com/google_containers/coredns                   v1.10.1   ead0a4a53df8   6 months ago    53.6MB
node5-196.com/google_containers/pause                     3.9       e6f181688397   10 months ago   744kB

（2）无harbor情况

#没有自建情况
[root@node1-190 ~]# vim dockerimages.sh 
#!/bin/bash
images=$(kubeadm config images list --kubernetes-version=1.28.2 | awk -F '/' '{print $NF}')
for i in ${images}
do
  docker pull registry.aliyuncs.com/google_containers/$i
done

3.master节点初始化（只在master节点做）

执行完脚本无误后执行以下命令

#master节点做，有自建harbor情况
kubeadm init --kubernetes-version=1.28.2 \   #一定要是真实版本
--apiserver-advertise-address=192.168.2.190 \    #自己master节点的IP
--image-repository node5-196.com/google_containers \    #镜像地址，自建harbor就写harbor的地址，没有就用阿里云的
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=Swap \
--cri-socket=unix:///var/run/cri-dockerd.sock
#没harbor情况
kubeadm init --kubernetes-version=1.28.2 \
--apiserver-advertise-address=192.168.2.190 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=Swap \
--cri-socket=unix:///var/run/cri-dockerd.sock

4.执行成功后出现此界面后进行权限设置

# master节点为普通用户时
[root@node1-190 ~]# mkdir -p $HOME/.kube && cp -i /etc/kubernetes/admin.conf $HOME/.kube/config && chown $(id -u):$(id -g) $HOME/.kube/config 
# master节点为root用户时
[root@node1-190 ~]# export KUBECONFIG=/etc/kubernetes/admin.conf

5.各个节点根据master初始化成功后的参数来加入（各个节点都做）

kubeadm join 192.168.2.190:6443 --token m5mkth.rb2e9rb3892fsu37 \
    --discovery-token-ca-cert-hash sha256:1209d580742d411fb4406953185ef9f27522b3ba150b8726fd39f364628d0942 \
    --cri-socket=unix:///var/run/cri-dockerd.sock 
#注意：初始化完成后弹出的加入节点命令在节点上执行时会报找不到socket文件，手动指定自己的socket文件“--cri-socket=unix:///var/run/cri-dockerd.sock”，或者如下将这个行命令export为变量，之后直接引用
[root@node1-190 ~]# tail -1 /etc/profile
export sock="--cri-socket=unix:///var/run/cri-dockerd.sock"
[root@node1-190 ~]# source /etc/profile
[root@node1-190 ~]# kubeadm join 192.168.2.190:6443 --token m5mkth.rb2e9rb3892fsu37 \
    --discovery-token-ca-cert-hash sha256:1209d580742d411fb4406953185ef9f27522b3ba150b8726fd39f364628d0942 \
    $sock

出现此界面即成功

[root@node1-190 ~]# kubectl get nodes
NAME            STATUS     ROLES           AGE    VERSION
node1-190.com   Ready      control-plane   121m   v1.28.2
node2-191.com   Ready      <none>          104m   v1.28.2
node3-192.com   Ready      <none>          96m    v1.28.2
node4-193.com   Ready      <none>          11m    v1.28.2
node5-196.com   Ready      <none>          9s     v1.28.2

七.收尾工作（master节点做）

1.命令补全配置

[root@node1-190 ~]# echo "source <(kubectl completion bash)" >> ~/.bashrc && echo "source <(kubeadm completion bash)" >> ~/.bashrc && source ~/.bashrc

2.网络配置

（1）flannel

[root@node1-190 ~]# vim flannel.sh
#!/bin/bash
for i in $(grep image kube-flannel.yml | grep -v '#' | awk -F '/' '{print $NF}')
do
  docker pull flannel/$i
  docker tag flannel/$i node5-196.com/google_containers/$i   #需要修改为刚创建的harbor的仓库地址
  docker push node5-196.com/google_containers/$i
  docker rmi flannel/$i
done
#注意：如果没有自建harbor，需要将node5-196.com改为registry.aliyuncs.com，后面的内容都如此
[root@node1-190 ~]# bash flannel.sh
[root@node1-190 ~]# docker images

http://be18.cn/k8s/calico.yaml

[root@master ~]# wget --no-check-certificate https://projectcalico.docs.tigera.io/archive/v3.25/manifests/calico.yaml
[root@master ~]# vim calico.yaml

找到CLUSTER_TYPE那行，添加后两行，ens33处填写你自己的网卡名称

- name: IP_AUTODETECTION_METHOD
  value: "interface=ens33"

将这两行取消注释，修改地址

- name: CALICO_IPV4POOL_CIDR
  value: "10.244.0.0/16"
