Since Kubernetes provides a function to manage a Docker cluster, it gives users an advantage to quickly deploy and manage a large scale system consisting of multiple Docker containers on multiple nodes. This presentation shares knowledge and issues obtained through providing enterprise users with the test system on Kubernetes. As the system is used by multiple development teams to test programs parallelly on middleware deployed in the hybrid cloud, and the data needs to be persistent, following requirements are considered:

A. Resources for each team should be managed separately and distributed evenly,
B. Linux privileges and kernel parameters should be changed to meet the requirements of middleware,
C. Appropriate persistent storage should be chosen to make container data persistent.

Also, compatibility issues on Docker and Kubernetes are shared.
