kubernetes组件

Master组件：

kube-apiserver
Kubernetes API，集群的统一入口，各组件协调者，以HTTP API提供接口服务，所有对象资源的增删改查和监听操作都交给APIServer处理后再提交

kube-controller-manager
处理集群中常规后台任务，一个资源对应一个控制器，而ControllerManager就是负责管理这些控制器的。

kube-scheduler
根据调度算法为新创建的Pod选择一个Node节点。

Node组件：

kubelet
kubelet是Master在Node节点上的Agent，管理本机运行容器的生命周期，比如创建容器、 Pod挂载数据卷、
下载secret、获取容器和节点状态等工作。 kubelet将每个Pod转换成一组容器。

kube-proxy
在Node节点上实现Pod网络代理，维护网络规则和四层负载均衡工作。

docker或rocket/rkt
运行容器。

第三方服务：

 etcd
分布式键值存储系统。用于保持集群状态，比如Pod、 Service等对象信息。

K8S部署

1、环境规划
2、安装Docker
3、自签TLS证书
4、部署Etcd集群
5、部署Flannel网络
6、创建Node节点kubeconfig文件
7、获取K8S二进制包
8、运行Master组件
9、运行Node组件
10、查询集群状态

1 环境规划

2 部署docker

node1 node2

mkdir  /data/docker
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo yum makecache fast
sudo yum -y install docker-ce

docker version
systemctl enable docker.service    
systemctl start docker.service

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF‘
{"graph": "/data/docker"}
EOF
sudo systemctl daemon-reload

sudo systemctl restart docker

3 自签TLS证书

技术分享图片
k8s-master 安装证书生成工具cfssl：

mkdir /data/ssl -p

wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64

chmod +x cfssl_linux-amd64 cfssljson_linux-amd64 cfssl-certinfo_linux-amd64

mv cfssl_linux-amd64 /usr/local/bin/cfssl
mv cfssljson_linux-amd64 /usr/local/bin/cfssljson
mv cfssl-certinfo_linux-amd64 /usr/bin/cfssl-certinfo

cd /data/ssl/

创建certificate.sh

{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}

下载二进制包

wget https://github.com/coreos/flannel/releases/download/v0.10.0/flannel-v0.10.0-linux-amd64.tar.gz

cd /data/flanneld
tar xf flannel-v0.10.0-linux-amd64.tar.gz
mv flanneld mk-docker-opts.sh  /opt/kubernetes/bin/

6 创建Node节点kubeconfig文件

master节点操作

创建TLS Bootstrapping Token
创建kubelet kubeconfig
创建kube-proxy kubeconfig

cd /data/ssl/
vim kubeconfig.sh          ##修改第10行 ip

# 创建 TLS Bootstrapping Token
export BOOTSTRAP_TOKEN=$(head -c 16 /dev/urandom | od -An -t x | tr -d ‘ ‘)
cat > token.csv <<EOF
${BOOTSTRAP_TOKEN},kubelet-bootstrap,10001,"system:kubelet-bootstrap"
EOF

#----------------------

# 创建kubelet bootstrapping kubeconfig
export KUBE_APISERVER="https://192.168.1.107:6443"

# 设置集群参数
kubectl config set-cluster kubernetes   --certificate-authority=./ca.pem   --embed-certs=true   --server=${KUBE_APISERVER}   --kubeconfig=bootstrap.kubeconfig

# 设置客户端认证参数
kubectl config set-credentials kubelet-bootstrap   --token=${BOOTSTRAP_TOKEN}   --kubeconfig=bootstrap.kubeconfig

# 设置上下文参数
kubectl config set-context default   --cluster=kubernetes   --user=kubelet-bootstrap   --kubeconfig=bootstrap.kubeconfig

# 设置默认上下文
kubectl config use-context default --kubeconfig=bootstrap.kubeconfig

#----------------------

# 创建kube-proxy kubeconfig文件

kubectl config set-cluster kubernetes   --certificate-authority=./ca.pem   --embed-certs=true   --server=${KUBE_APISERVER}   --kubeconfig=kube-proxy.kubeconfig

kubectl config set-credentials kube-proxy   --client-certificate=./kube-proxy.pem   --client-key=./kube-proxy-key.pem   --embed-certs=true   --kubeconfig=kube-proxy.kubeconfig

kubectl config set-context default   --cluster=kubernetes   --user=kube-proxy   --kubeconfig=kube-proxy.kubeconfig

kubectl config use-context default --kubeconfig=kube-proxy.kubeconfig

##  kubectl   软件在kubernetes-server-linux-amd64.tar.gz  里面,可从官网下载,下面的部署也需要这个软件包
mv kubectl  /usr/bin/
chmod +x /usr/bin/kubectl
sh kubeconfig.sh

kubeconfig.sh   kube-proxy-csr.json  kube-proxy.kubeconfig
kube-proxy.csr  kube-proxy-key.pem   kube-proxy.pem bootstrap.kubeconfig


scp *kubeconfig root@192.168.1.111:/opt/kubernetes/cfg
scp *kubeconfig root@192.168.1.14:/opt/kubernetes/cfg
