1 springboot 配置k8s中的redis服务名

#tomcat访问端口
# 应用名称
spring.application.name=demo
# 应用服务Web访问端口
server.port=8089
server.env=test
#缓存关闭
spring.thymeleaf.cache=false
#可选配置
management.endpoints.enabled-by-default=true
management.endpoints.web.base-path=/actuator
#暴露Prometheus数据端点  /actuator/prometheus
management.endpoints.web.exposure.include=prometheus
#暴露的Prometheus数据中添加application label
management.metrics.tags.application=demo
# Redis 连接信息 主机是k8s服务名.命名空间
spring.redis.host=redis-leader-service.rz-dt
spring.redis.port=6379
spring.redis.password=

2 k8s springboot部署脚本 test.sh

docker build -t k8s-springboot-demo:${image_tag} .
echo "制作镜像成功!"

echo "登录"
sudo docker login --username=aliyun0313112 rz-dt-image-server-registry-vpc.cn-shanghai.cr.aliyuncs.com --password=1234
