在一些企业的私有环境中可能无法连接外部的网络。如果要在这样的环境中部署Kubernetes集群,可以采集Kubernetes离线安装的方式进行部署。即:使用二进制安装包部署Kubernetes集群,采用的版本是Kubernetes v1.18.20。
下面通过具体的步骤来演示如何使用二进制包部署三个节点的Kubernetes集群。

1. 部署ETCD(1)从GitHub上下载ETCD的二进制安装包“etcd-v3.3.27-linux-amd64.tar.gz”。
(2)从cfssl官方网站上下载所需要的介质,并安装cfssl。
chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 mv cfssl_linux-amd64 /usr/local/bin/cfssl mv cfssljson_linux-amd64 /usr/local/bin/cfssljson

(3)创建用于生成CA证书和私钥的配置文件,执行下面的命令:
mkdir -p /opt/ssl/etcd cd /opt/ssl/etcd cfssl print-defaults config > config.json cfssl print-defaults csr > csr.jsoncat > config.json < < EOF"signing": "default": "expiry": "87600h" , "profiles": "kubernetes": "usages": [ "signing", "key encipherment", "server auth", "client auth" ], "expiry": "87600h"EOFcat > csr.json < < EOF"CN": "etcd", "key": "algo": "rsa", "size": 2048 , "names": [ "C": "CN", "ST": "BeiJing", "L": "BeiJing", "O": "k8s", "OU": "System" ]EOF

(4)生成CA证书和私钥。
cfssl gencert -initca csr.json | cfssljson -bare etcd

(5)在目录“/opt/ssl/etcd”下添加文件“etcd-csr.json”,该文件用于生成ETCD的证书和私钥,内容如下:
cat > etcd-csr.json < < EOF"CN": "etcd", "hosts": [ "192.168.79.11" ], "key": "algo": "rsa", "size": 2048 , "names": ["C": "CN", "ST": "BeiJing", "L": "BeiJing", "O": "etcd", "OU": "Etcd Security"]EOF

(6)安装ETCD。
tar -zxvf etcd-v3.3.27-linux-amd64.tar.gz cd etcd-v3.3.27-linux-amd64 cp etcd* /usr/local/bin mkdir -p /opt/platform/etcd/

(7)编辑文件“/opt/platform/etcd/etcd.conf”添加ETCD的配置信息,内容如下:
ETCD_NAME=k8s-etcd ETCD_DATA_DIR="/var/lib/etcd/k8s-etcd" ETCD_LISTEN_PEER_URLS="http://192.168.79.11:2380" ETCD_LISTEN_CLIENT_URLS="http://127.0.0.1:2379,http://192.168.79.11:2379" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.79.11:2380" ETCD_INITIAL_CLUSTER="k8s-etcd=http://192.168.79.11:2380" ETCD_INITIAL_CLUSTER_STATE="new" ETCD_INITIAL_CLUSTER_TOKEN="etcd-test" ETCD_ADVERTISE_CLIENT_URLS="http://192.168.79.11:2379"

(8)将ETCD服务加入系统服务中,编辑文件“/usr/lib/systemd/system/etcd.service”内容如下:
[Unit] Description=Etcd Server After=network.target After=network-online.target Wants=network-online.target[Service] Type=notify EnvironmentFile=/opt/platform/etcd/etcd.conf ExecStart=/usr/local/bin/etcd \\ --cert-file=/opt/ssl/etcd/etcd.pem \\ --key-file=/opt/ssl/etcd/etcd-key.pem \\ --peer-cert-file=/opt/ssl/etcd/etcd.pem \\ --peer-key-file=/opt/ssl/etcd/etcd-key.pem \\ --trusted-ca-file=/opt/ssl/etcd/etcd.pem \\ --peer-trusted-ca-file=/opt/ssl/etcd/etcd.pem Restart=on-failure LimitNOFILE=65536[Install] WantedBy=multi-user.target

(9)创建ETCD的数据存储目录,然后启动ETCD服务。
mkdir -p /opt/platform/etcd/data chmod 755 /opt/platform/etcd/data systemctl daemon-reload systemctl enable etcd.service systemctl start etcd.service

(10)验证ETCD的状态。
etcdctl cluster-health

输出信息如下:
member fd4d0bd2446259d9 is healthy: got healthy result from http://192.168.79.11:2379 cluster is healthy

(11)查看ETCD的成员列表。
etcdctl member list

输出的信息如下:
fd4d0bd2446259d9: name=k8s-etcd peerURLs=http://192.168.79.11:2380 clientURLs=http://192.168.79.11:2379 isLeader=true

(12)将ETCD的证书文件拷贝的node1和node2节点上。
cd /opt scp -r ssl/ root@node1:/opt scp -r ssl/ root@node2:/opt

2. 部署Flannel网络(1)在master节点上写入分配的子网段到ETCD中供Flannel使用,执行命令:
etcdctl set /coreos.com/network/config"Network": "172.17.0.0/16", "Backend": "Type": "vxlan"

(2)在master节点上查看写的Flannel子网信息,执行命令:
etcdctl get /coreos.com/network/config

输出的信息如下:
"Network": "172.17.0.0/16", "Backend": "Type": "vxlan"

(3)在node1上解压flannel-v0.10.0-linux-amd64.tar.gz安装包,执行命令:
tar -zxvf flannel-v0.10.0-linux-amd64.tar.gz

(4)在node1上创建Kubernetes工作目录。
mkdir -p /opt/kubernetes/cfg,bin,ssl mv mk-docker-opts.sh flanneld /opt/kubernetes/bin/

(5)在node1上定义Flannel脚本文件“flannel.sh”,输入下面的内容:
#!/bin/bash ETCD_ENDPOINTS=$1cat < < EOF > /opt/kubernetes/cfg/flanneld FLANNEL_OPTIONS="--etcd-endpoints=$ETCD_ENDPOINTS \\ -etcd-cafile=/opt/ssl/etcd/etcd.pem \\ -etcd-certfile=/opt/ssl/etcd/etcd.pem \\ -etcd-keyfile=/opt/ssl/etcd/etcd-key.pem" EOFcat < < EOF > /usr/lib/systemd/system/flanneld.service [Unit] Description=Flanneld overlay address etcd agent After=network-online.target network.target Before=docker.service[Service] Type=notify EnvironmentFile=/opt/kubernetes/cfg/flanneld ExecStart=/opt/kubernetes/bin/flanneld --ip-masq \\$FLANNEL_OPTIONS ExecStartPost=/opt/kubernetes/bin/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/subnet.env Restart=on-failure[Install] WantedBy=multi-user.target EOFsystemctl daemon-reload systemctl enable flanneld systemctl restart flanneld

(6)在node1节点上开启Flannel网络功能,执行命令:
bash flannel.sh http://192.168.79.11:2379

(7)在node1节点上查看Flannel网络的状态,执行命令:
systemctl status flanneld

输出的信息如下:
flanneld.service - Flanneld overlay address etcd agent Loaded: loaded (/usr/lib/systemd/system/flanneld.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2022-02-08 22:30:46 CST; 6s ago

(8)在node1节点上修改文件“/usr/lib/systemd/system/docker.service”配置node1节点上的Docker连接Flannel网络,在文件中增加下面的一行:
... ... EnvironmentFile=/run/flannel/subnet.env ... ...

(9)在node1节点上重启Docker服务。
systemctl daemon-reload systemctl restart docker.service

(10)查看node1节点上的Flannel网络信息,如图13-3所示:
