使用Docker/K8S部署项目流程-编程知识

使用Docker/K8S部署项目流程

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

4、打包docker镜像image并推送

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

docker push [dockerhub用户名]/vue-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-ui.yaml

apiVersion: v1
kind: Namespace
metadata:name: shop-ui---apiVersion: apps/v1
kind: Deployment
metadata:name: manager-uinamespace: shop-ui
spec:replicas: 1selector:matchLabels:app: manager-uitemplate:metadata:labels:app: manager-uispec:containers:- name: manager-uiimage: 192.168.1.48/shop-ui/vue-pro:1.0ports:- name: httpcontainerPort: 80

2、部署服务
