~~### 1. 服务迁移到k8s集群中~~

01-08 安装metallb模拟loadbalancer
```
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.11.0/manifests/namespace.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.11.0/manifests/metallb.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - 192.168.1.240-192.168.1.250
```

01-08 台式机安装了metallb，模拟loadbalancer，统一都不用带端口了
~~注意：笔记本上ingress是LoadBalancer，所以直接访问域名就行，实际是访问到loadbalancer的80端口，
而台式机是NodePort，所以域名需要加nodePort：http://chins-blog.me:31943/new~~
```
docker build -t chintensakai/learn-xxx:0.0.1 .
## docker save chintensakai/learn-xxx:0.0.1 -o learn-xxx.tar
helm package xxx
helm install xxx
```
```
docker run -itd -v /c/Users/toy_s/Documents/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest
docker run -itd -v /home/ubuntu/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest
```
### ~~1. 创建所需的docker容器~~

#### 1.1 nacos

```
## 修改mysql容器名和本机暴露端口，避免和mysql冲突
vim example/standalone-mysql-8.yaml
mysql:
    container_name: nacos-mysql
    ports:
      - "3316:3306"
      
## 修改nacos访问mysql的服务名，和上面mysql容器名对应
vim example/standalone-mysql-8.yaml
MYSQL_SERVICE_HOST=nacos-mysql

## 启动
docker-compose -f example/standalone-mysql-8.yaml up
```

#### 1.2 mysql

```
ubuntu:
sudo docker run -d --name mysql -v /home/ubuntu/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 mysql

widowns:
docker run -d --name mysql -v /c/Users/toy_s/Documents/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 mysql:8.0.16
```

##### 1.2.1 创建数据库

```
CREATE SCHEMA `learn-auth` DEFAULT CHARACTER SET utf8mb4 ;
```

### 2. 业务介绍

#### 2.1 learn-auth - 认证服务器

```
http://127.0.0.1:8800/oauth2/authorize?client_id=my-client&response_type=code&redirect_uri=http://127.0.0.1:2022/code-redirect
```

### 3. k8s部署
```
docker build -t chintensakai/learn-auth:0.0.1 .
```

### 0. 问题记录
2022-01-08
```
sudo groupadd docker #添加docker用户组
sudo gpasswd -a $USER docker #将当前用户添加至docker用户组
newgrp docker #更新docker用户组
```

问题：gateway 设置lb://xxxx，报503

解决：添加如下依赖
```<artifactId>spring-cloud-starter-loadbalancer</artifactId>```

1. mybatis-plus 报错： Could not resolve type alias ''
  
原因：parameterType="" 入参为List，这里空了忘记写，

改成：parameterType="java.util.List"

2. is not in the allowlist. If you believe this class is safe to deserialize
      
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS)

   @JsonIgnoreProperties(ignoreUnknown = true)

4. window.onload = function() {
     window.opener.postMessage([[${token}]], "http://127.0.0.1:8080");
     window.close();
     }
   前端项目必须用127.0.0.1:8080来访问，而不能用localhost:8080,否则收不到事件
2021-11-21：

discovery写成了discover，在笔记本上本机部署的nacos中一直没有发现，因为默认的server-addr就是127.0.0.1，而到了台式机上，nacos部署在ubuntu中，一下子就暴露出来了

2021-11-17：

{

"error": "invalid_grant"

}

请求体格式不对，参照rfc文档解决

1. '
   org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter'
   is deprecated

   -> 使用spring-authorization-server

+ No enum constant com.baomidou.config.rules.IdStrategy.assign_id

  mybatis 插件版本低，不支持assign_id

+ The parameters 'dataSource' for goal com.baomidou:mybatisplus-maven-plugin:1.0:code are missing or
  invalid

​ 直接运行插件就行

2021-11-15

+ 只有添加了starter-web，使它成为一个web项目，才能注册到nacos

+ 新版本不再默认加载bootstrap.yaml文件
