假设项目已经开发完成，部署流程如下：

一、制作镜像：

1、创建nginx配置文件default.conf

server {listen       80;server_name  localhost; # 修改为docker服务宿主机的iplocation / {root   /usr/share/nginx/html;index  index.html index.htm;try_files $uri $uri/ /index.html =404;}error_page   500 502 503 504  /50x.html;location = /50x.html {root   html;}
}

root /usr/share/nginx/html：这个目录和下面创建的Dockerfile中目录要保持一致

2、创建Dockerfile

FROM nginx:1.20.2MAINTAINER testRUN rm /etc/nginx/conf.d/default.confADD default.conf /etc/nginx/conf.d/COPY dist/ /usr/share/nginx/html

• FROM nginx -- 打包容器的底层来刚才先拉取的nginx
• MAINTAINER beizhu：备注
• RUN rm /usr/local/nginx/conf/nginx.conf.default：删除目录下的nginx.conf.default 文件
• ADD nginx.conf.default /usr/local/nginx/conf/：将default.conf复制到/usr/local/nginx/conf/下，用本地的default.conf配置来替换nginx镜像里的默认配置
• COPY dist/ /usr/local/nginx/html/：将项目根目录下dist文件夹（构建之后才会生成）下的所有文件复制到镜像/usr/local/nginx/html/目录下上一步root地址

3、准备静态模板（项目）

4、打包docker镜像image并推送

docker build -f Dockerfile -t [dockerhub用户名]/web-pro:1.0 .

docker push [dockerhub用户名]/web-pro:1.0

如果是用的阿里云镜像，请参照阿里云镜像推送方式。 

二、K8S部署： 

1、编写 K8S yaml 文件

vi deploy-web.yaml

apiVersion: v1
kind: Namespace
metadata:name: shop-web---apiVersion: apps/v1
kind: Deployment
metadata:name: manager-webnamespace: shop-web
spec:replicas: 1selector:matchLabels:app: manager-webtemplate:metadata:labels:app: manager-webspec:containers:- name: manager-webimage: registry.cn-hangzhou.aliyuncs.com/samve/k8s:2.0ports:- name: httpcontainerPort: 80
---apiVersion: v1
kind: Service
metadata:name: manager-ui-servicenamespace: shop-web
spec:selector:app: manager-webports:- name: httpprotocol: TCPport: 80targetPort: 80nodePort: 30001type: NodePort

2、部署服务

kubectl apply -f deploy-web.yaml

三、使用helm部署：

1、准备环境 k8s集群

[root@k8s-master-136 ~]# kubectl get node
NAME             STATUS   ROLES                  AGE    VERSION
k8s-master-136   Ready    control-plane,master   296d   v1.21.0
k8s-node-135     Ready    <none>                 296d   v1.21.0
k8s-node-137     Ready    <none>                 296d   v1.21.0

2、创建一个模板的chart包，删除原来的内容，自定义成我们自己需要的内容，后面我们自定义部署的yaml文件

[root@k8s-master-136 ~]# helm create nginx-chart
Creating nginx-chart
[root@k8s-master-136 nginx-chart]# cd ./nginx-chart/templates/
[root@k8s-master-136 templates]# rm -rf ./*

自定义部署的模板yaml文件:

vim templates/nginx-deploy-service.yaml

nginx-deploy-service.yaml

apiVersion: v1
kind: Namespace
metadata:name: {{.Values.namespace}}---apiVersion: apps/v1
kind: Deployment
metadata:name: {{.Values.deployment_name}}namespace: {{.Values.namespace}}
spec:replicas: {{.Values.replicas}}selector:matchLabels:app: {{.Values.pod_label}}template:metadata:labels:app: {{.Values.pod_label}}spec:containers:- name: {{.Values.pod_label}}image: registry.cn-hangzhou.aliyuncs.com/samve/k8s:2.0ports:- name: httpcontainerPort: {{.Values.containerport}}
---apiVersion: v1
kind: Service
metadata:name: {{.Values.service_name}}namespace: {{.Values.namespace}}
spec:selector:app: {{.Values.pod_label}}ports:- name: httpprotocol: TCPport: {{.Values.port}}targetPort: {{.Values.targetport}}nodePort: {{.Values.nodeport}}type: NodePort

[root@k8s-master-136 nginx-chart]# vim values.yaml 

values.yaml

deployment_name: manager-web
service_name: manager-web-service
namespace: shop-web
pod_label: manager-web
replicas: 2
port: 80
targetport: 80
containerport: 80
nodeport: 30002

3、通过chart包安装一个release实例

[root@k8s-master-136 ~]# helm install nginx-service ./nginx-chart
NAME: nginx-service
LAST DEPLOYED: Sun Nov 19 21:50:28 2023
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None

[root@k8s-master-136 nginx-chart]# vim values.yaml 
[root@k8s-master-136 nginx-chart]# helm list
NAME            NAMESPACE       REVISION        UPDATED                                 STATUS          CHART                   APP VERSION
nginx-service   default         1               2023-11-19 21:50:28.744590789 +0800 CST deployed        nginx-chart-0.1.0       1.16.0
