用k8s部署简单应用
本次部署两个后端java服务 一个前端dist包
1、制作镜像
uap-server镜像
点击查看代码
FROM openjdk:8-jdk-slim
label maintainer=mhfang3
#LANGUAGE ENV
ENV LANG C.UTF-8
ENV LANGUAGE en_US:en
#设置容器时间
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone
# 安装系统依赖
RUN apt-get update && \
apt-get install -y \
fontconfig \
fonts-wqy-microhei \
procps && \
rm -rf /var/lib/apt/lists/*
ADD ./config/ /usr/share/config/
COPY ./uap-server.jar /usr/share/
EXPOSE 8980
#指定容器启动程序及参数
ENTRYPOINT ["java","-Djasypt.encryptor.password=uap@ifly123456","-Dspring.config.location=file:/usr/share/config/application.properties", "-Dfile.encoding=utf-8", "-jar","/usr/share/uap-server.jar"]

uap-web镜像
点击查看代码
FROM nginx:alpine
label maintainer=mhfang3
# 删除默认的 Nginx 配置
RUN rm -rf /usr/share/nginx/html/*
# 复制构建好的文件到 Nginx 的公共目录
COPY ./dist /usr/share/nginx/html
# 复制自定义的 Nginx 配置文件（如果有）
COPY nginx.conf /etc/nginx/nginx.conf
# 暴露端口
EXPOSE 80
# 启动 Nginx
CMD ["nginx", "-g", "daemon off;"]
2、K8s部署
