Rocket v1.10.0 发布 CoreOS 容器引擎

Rocket v1.10.0 发布了，改进记录如下：

增强

ARM64 support
A new subcommand rkt stop to gracefully stop running pods
native Go vendoring with Glide
rkt is now packaged for openSUSE Tumbleweed and Leap

新特性

Add ARM64 support (#2758). This enables ARM64 cross-compliation, fly, and stage1-coreos.
Replace Godep with Glide, introduce native Go vendoring (#2735).
rkt: rkt stop (#2438). Cleanly stops a running pod. For systemd-nspawn, sends a SIGTERM. For kvm, executes systemctl halt.

Bug 修复

stage1/fly: respect runtimeApp App’s MountPoints (#2852). Fixes #2846.
run: fix sandbox-side metadata service to comply to appc v0.8.1 (#2863). Fixes #2621.

其他改进

build directory layout change (#2758): The rkt binary and stage1 image files have been moved from the ‘bin’ sub-directory to the ‘target/bin’ sub-directory.
networking/kvm: add flannel default gateway parsing (#2859).
stage1/enterexec: environment file with ‘\n’ as separator (systemd style) (#2839).
pkg/tar: ignore global extended headers (#2847).
pkg/tar: remove errwrap (#2848).
tests: fix abuses of appc types.Isolator (#2840).
common: remove unused GetImageIDs() (#2834).
common/cgroup: add mountFsRO() helper function (#2829).
Documentation updates (#2732, #2869, #2810, #2865, #2825, #2841, #2732)

Library 更新

glide: bump ql to v1.0.4 (#2875). It fixes an occassional panic when doing GC.
glide: bump gopsutils to 2.1 (#2876). To include shirou/gopsutil#194 (this adds ARM aarch64 support)
vendor: update appc/spec to 0.8.5 (#2854).

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。
