Kubernetes 集群安装部署

etcd集群配置

master节点配置

1.安装kubernetes etcd

 [root@k8s ~]# yum -y install kubernetes-master etcd

2.配置 etcd 选项

 [root@k8s ~]# cat /etc/etcd/etcd.conf

 #[Member]

 ETCD_DATA_DIR="/var/lib/etcd/default.etcd"

 ETCD_LISTEN_PEER_URLS="http://172.19.15.92:2380"

 ETCD_LISTEN_CLIENT_URLS="http://172.19.15.92:2379,http://127.0.0.1:2379"

 ETCD_MAX_SNAPSHOTS=""

 ETCD_NAME="etcd1"

 ETCD_HEARTBEAT_INTERVAL=6000

 ETCD_ELECTION_TIMEOUT=30000

 #[Clustering]

 ETCD_INITIAL_ADVERTISE_PEER_URLS="http://172.19.15.92:2380"

 ETCD_ADVERTISE_CLIENT_URLS="http://172.19.15.92:2379"

 ETCD_INITIAL_CLUSTER="etcd1=http://172.19.15.92:2380,etcd2=http://172.19.15.93:2380,etcd3=http://172.19.15.94:2380"

nodes节点配置

1.安装部署kubernetes-node /etcd /flannel /docker

 [root@k8s-node1 ~]# yum -y install kubernetes-node etcd flannel docker

2.分别配置etcd，node1 与 node2 的配置方法相同，以 node1 配置文件为例说明

 [root@k8s-node1 ~]# cat /etc/etcd/etcd.conf

 #[Member]

 ETCD_DATA_DIR="/var/lib/etcd/default.etcd"

 ETCD_LISTEN_PEER_URLS="http://172.19.15.93:2380"

 ETCD_LISTEN_CLIENT_URLS="http://172.19.15.93:2379,http://127.0.0.1:2379"

 ETCD_NAME="etcd2"

 ETCD_HEARTBEAT_INTERVAL=6000

 ETCD_ELECTION_TIMEOUT=30000

 #[Clustering]

 ETCD_INITIAL_ADVERTISE_PEER_URLS="http://172.19.15.93:2380"

 ETCD_ADVERTISE_CLIENT_URLS="http://172.19.15.93:2379"

 ETCD_INITIAL_CLUSTER="etcd1=http://172.19.15.92:2380,etcd2=http://172.19.15.93:2380,etcd3=http://172.19.15.94:2380"

启动etcd cluster

分别在3台服务器启动etcd

 [root@k8s ~]# systemctl start etcd.service

 [root@k8s ~]# systemctl status etcd.service -l

 ● etcd.service - Etcd Server

    Loaded: loaded (/usr/lib/systemd/system/etcd.service; enabled; vendor preset: disabled)

    Active: active (running) since 二 2018-07-03 18:13:06 CST; 16h ago

  Main PID: 2085 (etcd)

     Tasks: 31

    Memory: 328.4M

    CGroup: /system.slice/etcd.service

            └─2085 /usr/bin/etcd --name=etcd1 --data-dir=/var/lib/etcd/default.etcd --listen-client-urls=http://172.19.15.92:2379,http://127.0.0.1:2379

查看etcd集群状态

 [root@k8s ~]# etcdctl cluster-health

 member 8c24796af2c20350 is healthy: got healthy result from http://172.19.15.94:2379

 member edfc36869b54e803 is healthy: got healthy result from http://172.19.15.92:2379

 cluster is healthy

Kubernetes集群配置

master节点配置

1.apiserver配置文件修改，注意KUBE_ADMISSION_CONTROL选项的参数配置

 [root@k8s ~]# cat /etc/kubernetes/apiserver

 KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"

 KUBE_API_PORT="--port=8080"

 KUBELET_PORT="--kubelet-port=10250"

 KUBE_ETCD_SERVERS="--etcd-servers=http://172.19.15.92:2379,http://172.19.15.93:2379,http://172.19.15.94:2379"

 KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"

 KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,ResourceQuota"

 KUBE_API_ARGS=""

2.启动服务

 [root@k8s ~]# systemctl start kube-apiserver

 [root@k8s ~]# systemctl start kube-controller-manager

 [root@k8s ~]# systemctl start kube-scheduler

 [root@k8s ~]# systemctl enable kube-apiserver

 [root@k8s ~]# systemctl enable kube-controller-manager

 [root@k8s ~]# systemctl enable kube-scheduler

nodes节点配置

1.配置config配置，node1&node2配置相同，以node1为例说明

 [root@k8s-node1 ~]# cat /etc/kubernetes/config

 KUBE_LOGTOSTDERR="--logtostderr=true"

 KUBE_LOG_LEVEL="--v=0"

 KUBE_ALLOW_PRIV="--allow-privileged=false"

 KUBE_MASTER="--master=http://172.19.15.92:8080"

2.配置kubelet

 [root@k8s-node1 ~]# cat /etc/kubernetes/kubelet

 KUBELET_ADDRESS="--address=127.0.0.1"

 KUBELET_HOSTNAME="--hostname-override=172.19.15.93"

 KUBELET_API_SERVER="--api-servers=http://172.19.15.92:8080"

 KUBELET_POD_INFRA_CONTAINER="--pod-infra-container-image=registry.access.redhat.com/rhel7/pod-infrastructure:latest"

 KUBELET_ARGS=""

3.docker service配置文件

 [root@k8s-node1 ~]# cat /usr/lib/systemd/system/docker.service

 [Unit]

 Description=Docker Application Container Engine

 Documentation=https://docs.docker.com

 After=network.target firewalld.service

 [Service]

 Type=notify

 Environment="http_proxy=http://192.168.59.241:8888/" "https_proxy=https://192.168.59.241:8888/"

 ExecStart=/usr/bin/dockerd --registry-mirror=http://f2d6cb40.m.daocloud.io --bip=192.100.90.1/24

 ExecReload=/bin/kill -s HUP $MAINPID

 LimitNOFILE=infinity

 LimitNPROC=infinity

 LimitCORE=infinity

 TimeoutStartSec=0

 Delegate=yes

 KillMode=process

 [Install]

 WantedBy=multi-user.target

网络配置

这里使用flannel进行网络配置，已经在2个节点上安装，下面进行配置。

在节点上进行配置flannel

 [root@k8s-node1 ~]# cat /etc/sysconfig/flanneld

 FLANNEL_ETCD_ENDPOINTS="http://172.19.15.92:2379,http://172.19.15.93:2379,http://172.19.15.94:2379"

 FLANNEL_ETCD_PREFIX="/k8s/network"

 FLANNEL_OPTIONS="--logtostderr=true --log_dir=/var/log/k8s/flannel/ --etcd-prefix=/k8s/network  --etcd-endpoints=http://172.19.15.92:2379,http://172.19.15.93:2379,http://172.19.15.94:2379 --iface=ens160"

master 节点需要配置 etcd 网络：

 etcdctl set /k8s/network/config '{"Network":"192.100.0.1/16"}'

2.启动服务

 [root@k8s-node1 ~]# systemctl start kubelet

 [root@k8s-node1 ~]# systemctl start docker

 [root@k8s-node1 ~]# systemctl start flanneld

 [root@k8s-node1 ~]# systemctl enable kubelet

 [root@k8s-node1 ~]# systemctl enable docker

 [root@k8s-node1 ~]# systemctl enable flanneld

查看集群状态

 [root@k8s ~]# kubectl get nodes

 NAME           STATUS    AGE

 172.19.15.92   Ready     16h

 172.19.15.93   Ready     1d

 172.19.15.94   Ready     1d

 [root@k8s ~]# etcdctl  member list

 8c24796af2c20350: name=etcd3 peerURLs=http://172.19.15.94:2380 clientURLs=http://172.19.15.94:2379 isLeader=false

 e66597512233d97d: name=etcd2 peerURLs=http://172.19.15.93:2380 clientURLs=http://172.19.15.93:2379 isLeader=false

 edfc36869b54e803: name=etcd1 peerURLs=http://172.19.15.92:2380 clientURLs=http://172.19.15.92:2379 isLeader=true

 [root@k8s ~]# etcdctl cluster-health

 member 8c24796af2c20350 is healthy: got healthy result from http://172.19.15.94:2379

 member e66597512233d97d is healthy: got healthy result from http://172.19.15.93:2379

 member edfc36869b54e803 is healthy: got healthy result from http://172.19.15.92:2379

 cluster is healthy

更改 docker 网段为 flannel 分配的网段

 # export FLANNEL_SUBNET=10.254.26.1/24

 # cat << EOF > /etc/docker/daemon.json

 {

   "bip" : "$FLANNEL_SUBNET"

 }

 EOF

 # systemctl daemon-reload

 # systemctl restart docker
