Spring Cloud 应用

apply plugin: 'org.springframework.boot'

//默认行为
bootJar {
	enabled = true
}
jar {
	enabled = true
}

执行

./gradlew clean build

构建普通jar包（用于被其他服务依赖）和bootJar包

Dockerfile

# 选择轻量级基础镜像（推荐）
FROM eclipse-temurin:17.0.15_6-jre-ubi9-minimal

# 设置工作目录
WORKDIR /app

# 复制JAR文件到容器
COPY build/libs/gateway.jar app.jar

# 暴露服务端口（与实际端口一致）
EXPOSE 8080

# 启动命令
ENTRYPOINT ["java", "-jar", "app.jar"]

Nginx

Dockerfile

FROM nginx:stable-alpine

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d/

COPY dist/ /usr/share/nginx/html/

EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

nginx.conf

server {
  listen 80;
  server_name localhost;
  
  location / {
    root /usr/share/nginx/html;
    index index.html;
    try_files $uri $uri/ /index.html;
  }
  
  error_page 500 502 503 504 /50x.html;
  location = /50x.html {
    root /usr/share/nginx/html;
  }
}

Minikube

可能存在网络问题，在 Docker Desktop 提前拉取镜像后

minikube start --driver=docker \
--base-image="kicbase/stable:v0.0.45" --memory=7500mb --cpus=4

kubectl apply -f k8s/volumes/
kubectl apply -f k8s/config/
