rkt v1.30.0 发布了。Rocket（也叫 rkt）是 CoreOS 推出的一款容器引擎，和 Docker 类似，帮助开发者打包应用和依赖包到可移植容器中，简化搭环境等部署工作。Rocket 和 Docker 不同的地方在于，Rocket 没有 Docker 那些为企业用户提供的“友好功能”，比如云服务加速工具、集群系统等。反过来说，Rocket 想做的，是一个更纯粹的业界标准。
相信的更新内容如下。
新特性
- status: added read from uuid-file (#3860).
- stage0/run: relax ‘–hosts-entry’ parser (#3833).
- iottymux: store logs for kubelet in the appropriate location (#3798). This change is made for rktlet. iottymux will store the logs directly in the CRI format.
