Kubernetes

Service的唯一性和顺序部署适用于需要持久化存储、网络标识、状态管理等场景。

MongoDB

NoSQL

/var/log/mongodb/mongod.loglogAppend:

truestorage:dbPath:

mongo-0.mongodb-service-headless.default.svc.cluster.local

mongo-1.mongodb-service-headless.default.svc.cluster.local

mongo-2.mongodb-service-headless.default.svc.cluster.local

这样我们就成功地使用

/data/nodes.confcluster-node-timeout

15000创建一个

redis-0.redis-service-headless.default.svc.cluster.local

redis-1.redis-service-headless.default.svc.cluster.local

redis-2.redis-service-headless.default.svc.cluster.local

这样我们就成功地使用

是一种非常流行的分布式搜索和数据分析引擎支持集群部署和数据持久化等功能。
