新闻 rkt 1.13.0 发布，CoreOS 的容器引擎 下载

rkt 1.13.0 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。

本次版本新特性和 UX 的改进：

• 
  export: name flag for exporting multi-app pods (#3030).
  
  
• 
  stage1: limit device node creation/reading/writing with DevicePolicy= and DeviceAllow= (#3027,#3058).
  
  
• 
  rkt: implements --insecure-options={capabilities,paths,seccomp,run-all} (#2983).
  

Bug 修复：

• 
  kvm: use a properly formatted comment for iptables chains (#3038). rkt was using the chain name as comment, which could lead to confusion.
  
  
• 
  pkg/label: supply mcsdir as function argument to InitLabels() (#3045).
  
  
• 
  api_service: improve machined call error output (#3059).
  
  
• 
  general: fix old appc/spec version in various files (#3055).
  
  
• 
  rkt/pubkey: use custom http client including timeout (#3084).
  
  
• 
  dist: remove quotes from rkt-api.service ExecStart (#3079).
  
  
• 
  build: multiple fixes (#3042, #3041, #3046).
  
  
• 
  configure: disable tests on host flavor with systemd <227 (#3047).
  

其他改进：

• 
  travis: add go 1.7, bump go 1.5/1.6 (#3077).
  
  
• 
  api_service: Add lru cache to cache image info (#2910).
  
  
• 
  scripts: add curl as build dependency (#3070).
  
  
• 
  vendor: use appc/spec 0.8.6 and k8s.io/kubernetes v1.3.0 (#3063).
  
  
• 
  common: use fileutil.IsExecutable() (#3023).
  
  
• 
  build: Stop printing irrelevant invalidation messages (#3050).
  
  
• 
  build: Make generating clean files simpler to do (#3057).
  
  
• 
  Documentation: misc changes (#3053, #2911, #3035, #3036, #3037, #2945, #3083, #3076, #3033,#3064, #2932).
