Vue.js + axios(ajax) + Beego Restful api + Mysql + Nginx 目前已经进行初步容器化，可在 k8s 集群上快速部署
- 暂时只迁移一篇文章
- 演示地址
- 首页
-
侧边栏
-
阅读界面
-
后台登录界面
- 后台管理界面
- 以Ubuntu为例
- 必须要有能正常工作，拉取镜像的 k8s 集群
- 首先需要一个可以工作的 k8s 集群
- Mysql 默认密码是 sinksmell
- 后台管理账号和密码均是 sinksmell
- 配置文件在 conf/app.conf 里面可以修改登录密码，但是要重新编译镜像，在yaml文件中替换镜像版本

借助nginx向外暴露服务，需要事先安装 nginx 和 80，9090 两个端口
安装的Nginx有一个默认的Server 占用了 80 端口 手动删除
# 删除默认server
rm /etc/nginx/sites-enabled/default
# 拷贝lanblog.conf到 /etc/nginx/conf.d
cp front/lanblog.conf /etc/nginx/conf.d/lanblog.conf
# 查看gateway服务的clusterIP 本例中是 10.152.183.118
kubectl get svc
# 修改 /etc/nginx/conf.d/lanblog.conf 中的 proxy_pass 将 ip 替换为 上述ip
# 以下是修改后的结果
server {
listen 80;
server_name localhost;
# access_log /root/blog.log main;
location / {
proxy_pass http://10.152.183.118:80/ ;
}
}
server {
listen 9090;
server_name localhost;
# access_log /root/blog.log main;
location / {
proxy_pass http://10.152.183.118:9090/ ;
}
}
# 重新加载配置文件
nginx -s reload1. 输入IP访问博客界面
2. 输入IP:9090访问后台管理界面
