在Linux服务器，一键搭建K8s服务【脚本篇】（转）
前言
好久没有写博客了，本文主要是对网上文章的总结篇，主要是将安装和运行代码做了一次真机实验，亲测可用。文章内包含的脚本和代码，多来自于网络，也有我自己的调整和配置，文章末尾对参考的文献做了列举，方便大家参考。
过程很简单，一路next往下看和操作即可，文章不对脚本和代码做原理解释，某些注意点加了红色标注，部分脚本有注释，可以自行参考，以后有机会可以视频讲解。
核心步骤
因为是next的方式，所以本章节主要是操作步骤，步骤中涉及到的代码或者脚本，可以在下文中找到，比如：附录代码一、附录代码二等等，因为脚本实在太长，不太方便放到步骤里。
1、配置 node01 主节点（2个文件，1个结果）；
在root目录下拷贝k8s脚本（附录代码一：kubernetes_node01.sh）和flannel网络（附录代码二：kube-flannel.yml）的文件；
然后给脚本文件赋权限：chmod +x kubernetes_node01.sh
最后执行脚本：./kubernetes_node01.sh
ps：1、sh脚本中，需要配置节点，是内网的。
2、多个节点之间要保证能ping通；
3、中间可能需要自己来配合做些操作，比如输入：y，来做确认等等。
最后，可以在当前文件夹下，看到一个key.txt的文件，里边有安装的结果数据或者密钥等，可查看附录代码三：key.txt，这是我安装的结果，里边有join主节点的配置语句。
查看所有的nodes和pods：
[root@node01 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
node01 Ready master 26h v1.18.0
所有的pods：
[root@node01 ~]# kubectl get pods -A
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-7ff77c879f-6m6fl 1/1 Running 0 25m
kube-system coredns-7ff77c879f-dkd56 1/1 Running 0 25m
kube-system etcd-node01 1/1 Running 0 26m
kube-system kube-apiserver-node01 1/1 Running 0 26m
kube-system kube-controller-manager-node01 1/1 Running 0 26m
kube-system kube-flannel-ds-amd64-sdv2h 1/1 Running 0 25m
kube-system kube-proxy-vgf4r 1/1 Running 0 25m
kube-system kube-scheduler-node01 1/1 Running 0 26m
如果都启动，都READY了，表示安装成功。
2、配置dashboard仪表盘（2个文件）
上面安装好了kubectl、kubeadm、kubelet后，我们可以通过客户端来连接，这里安利下k8s的客户端：Lens，很香。
如果不用客户端，那就需要安装仪表盘了。
1、Linux根目录拷贝文件，附录代码四：recommended.yaml（安装看板），附录代码五：dashboard-svc-account.yaml（配置管理员账户）
2、执行命令：
sed -i '/targetPort: 8443/a\ \ \ \ \ \ nodePort: 30001\n\ \ type: NodePort' recommended.yaml
3、启动仪表盘服务：
kubectl apply -f recommended.yaml
4、启动配置账户：
kubectl apply -f dashboard-svc-account.yaml
都成功后，会生成一个token字符串，用来登录web端的令牌的，如果没有拷贝或者丢失了也不怕，可以使用命令查看：
kubectl describe secrets -n kube-system `kubectl get secret -n kube-system | grep admin | awk '{print $1}'` | grep '^token'|awk '{print $2}'
token就是类似这种：
eyJhbGciOiJSUzI1NiIsImtpZCI6Ikl5SE00cXFZR1V2cWstQURVcGlUOGk4cTBYekZMV0VmNDEwRy14UTd1d2sifQ.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.BBtdG-S2kHEwRbWIAf6DiUgC3ILUOStPATyWfvxcQs5VJBtLRyMGqQ-AfkUoVLuhZdUv-CGoEJ1OYA00M6MwoehDdkhLFbXF7Xx1IPyhFTHxZ_oXHBPyjEREkTEerarZnvgt0ufU4g_Eqn91jdHet73itz-0abgmLMPkRl5YYjlh36Ivwq9IjKgujLwTNisUFckLuHOscHtQIrjIvAZlWTRh_awMsDHvemAKG_YIjMbyQnXi6VfN3rTW869DA0XAGOF2t7cWBtMmHvmLxVYqpOauUzwXXeYbO9eP0_d9JtVwKv6R0Q7sexRFZ-iTdZBOJDujFI3UT2jsqgVdbagA
这里再检查下：
查看所有的nodes和pods：
[root@node01 ~]# kubectl get pods -A
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system coredns-7ff77c879f-6m6fl 1/1 Running 0 25m
kube-system coredns-7ff77c879f-dkd56 1/1 Running 0 25m
kube-system etcd-node01 1/1 Running 0 26m
kube-system kube-apiserver-node01 1/1 Running 0 26m
kube-system kube-controller-manager-node01 1/1 Running 0 26m
kube-system kube-flannel-ds-amd64-sdv2h 1/1 Running 0 25m
kube-system kube-proxy-vgf4r 1/1 Running 0 25m
kube-system kube-scheduler-node01 1/1 Running 0 26m
kubernetes-dashboard dashboard-metrics-scraper-78f5d9f487-ldswx 1/1 Running 0 12m
kubernetes-dashboard kubernetes-dashboard-577bd97bc-szvwt 1/1 Running 0 12m
多了kubernetes-dashboard命名空间下的两个pod。
3、配置 node02 子节点（1个文件）
如果你没有多余的服务器，也可以在master节点做自己的pod的，需要开启下，命令将 master 标记为可调度：
sudo kubectl taint nodes --all node-role.kubernetes.io/masteflr-
如果要配置多个子节点，那就仿照主节点来继续写sh脚本吧（附录代码六：kubernetes_node02.sh），步骤和主节点一致：
1、拷贝到子节点服务器；
2、赋权限，执行文件：./kubernetes_node02.sh
3、这里不用flannel配置；
4、安装完成后，可以join到主节点，配置文件在主节点的key.txt文件里，如果你安装成功了的话；
kubeadm join 172.17.10.4:6443 --token q3uu1o.4rdfkcyzxjhawvk1 \
--discovery-token-ca-cert-hash sha256:a755d8f56733ba8f9d1951298b200202fce7b84389954bf7a38558fa6ce2a9c9
如果一切正常，可以去主节点查看所有的nodes：
NAME STATUS ROLES AGE VERSION
node01 Ready master 26h v1.18.0
node02 Ready <none> 25h v1.18.0
表示我们的子节点已经配置完成。
4、配置ASP.Net Core服务
这里的Deployment+Service的写法比较简单，直接贴出来，就不做过多的解释了。
apiVersion: apps/v1
kind: Deployment
metadata:
labels:
app: laozhang-op2
name: laozhang-op2
spec:
selector:
matchLabels:
app: laozhang-op2
replicas: 2
template:
metadata:
labels:
app: laozhang-op2
spec:
containers:
- name: laozhang-op2
image: laozhangisphi/apkimg315
imagePullPolicy: IfNotPresent #pull镜像时机，
----
apiVersion: v1
kind: Service
metadata:
name: laozhang-op2
spec:
type: NodePort
ports:
- name: default
protocol: TCP
port: 80
targetPort: 80
nodePort: 30099
selector:
app: laozhang-op2
但是这种是nodePort的方式，平时使用更多的是Ingress的方式，那使用ingress，就先需要配置ingress的服务。
5、配置Ingress-nginx（1个文件）
在根目录拷贝文件，附录代码七：mandatory.yaml，配置Ingress-Nginx服务，
这里需要注意下，如果服务器之前已经配置过nginx，需要在mandatory.yaml文件中，修改http-port输出端口，详细内容见下面的代码，有注释。
直接执行yaml：
kubectl apply -f mandatory.yaml
如果没有报错，可以查看所有的pods：
[root@node01 ~]# kubectl get pods -A
NAMESPACE NAME READY STATUS RESTARTS AGE
default laozhang-op2-5cf487b57f-pdvfg 1/1 Running 0 4h29m
default laozhang-op2-5cf487b57f-vtgwc 1/1 Running 0 4h29m
ingress-nginx nginx-ingress-controller-557475687f-rfl98 1/1 Running 0 122m
kube-system coredns-7ff77c879f-gj4sl 1/1 Running 0 26h
kube-system coredns-7ff77c879f-mqp2q 1/1 Running 0 26h
kube-system etcd-node01 1/1 Running 0 26h
kube-system kube-apiserver-node01 1/1 Running 0 26h
kube-system kube-controller-manager-node01 1/1 Running 0 26h
kube-system kube-flannel-ds-amd64-nmnj2 1/1 Running 0 26h
kube-system kube-proxy-wcjb8 1/1 Running 0 26h
kube-system kube-scheduler-node01 1/1 Running 2 26h
kubernetes-dashboard dashboard-metrics-scraper-78f5d9f487-qp2fw 1/1 Running 0 26h
kubernetes-dashboard kubernetes-dashboard-577bd97bc-2tsj7 1/1 Running 0 26h
如果和上面一样，那恭喜，一切配置就完成了。
