以容器方式部署在docker swarm 或 k8s环境中
当前分支内容是k8s部署
先修改根目录的pom.xml中的 <docker.registry.url></docker.registry.url> 改为自己的私库地址
- 首先在项目根目录
mvn clean install -Dmaven.test.skip=true- 分别进入三个子项目中执行打包命令如果uuid-eureka-server
cd uuid-eureka-server/
mvn package docker:build -Dmaven.test.skip=true打包成功后将镜像上传到私有库或公共库中，我这里是个人的私有库
docker push 172.16.10.192:5000/bobo/uuid-eureka-server
docker push 172.16.10.192:5000/bobo/uuid-server
docker push 172.16.10.192:5000/bobo/uuid-snowflake-client查看分支 cluster-v1.0
- 执行命令
docker stack deploy -c docker-swarm-compose.yml --with-registry-auth id-app- service
[root@manager uuid-generate]# docker service ls

1. 本实例在k8s中 uuid-eureka-server和uuid-server 只部署一个实例
2. 使用的docker私有库，请参考[k8s 从私有仓库拉取镜像](https://www.jianshu.com/p/3f24bbee72ad)
cd uuid-eureka-server/
mvn package docker:build -Dmaven.test.skip=true
cd uuid-server/
mvn package docker:build -Dmaven.test.skip=true
cd uuid-snowflake-client/
mvn package docker:build -Dmaven.test.skip=true- 先发布Eureka-Server, 执行根目录的 eureka-k8s.yaml
kubectl create -f eureka-k8s.yaml- 执行发布 uuid-server和uuid-snowflake-client 执行根目录的 uuid-k8s.yaml
kubectl create -f uuid-k8s.yaml 查看pod

- uuid-server的日志
INFO 1 --- [pool-7-thread-1] c.l.u.s.u.UuidServerApplication : 应用关联的种子 2
INFO 1 --- [pool-7-thread-1] c.l.u.s.u.UuidServerApplication : 服务应用注册数量： 2应用关联的种子 和 服务应用注册数量 相等时，表示正常，否则表示有异常
uuid-server项目主要工作是初始化 workid和dataCenterId到redis中，并监控redis中的关联池与实际Eureka-server中注册服务的变化， 监控的任务
task-execution-interval: 30默认30秒执行一次，由于在生产环境中，uuid-snowflake-client注册的数量不确定，所以需要设置足够大的时长，10分钟以上， 30秒为测试环境。
