rkt v1.4.0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。 更新详情： 新特性和 UX changes config: add config subcommand (#2405). This new subcommand prints the current rkt configuration. It can be used to get i.e. authentication credentials. See rkt's config subcommanddocumentation. run: add --user/--group app flags to rkt run and rkt prepare allowing to override the user and group specified in the image manifest (#2419). gc: Add flag 'mark-only' to mark garbage pods without deleting them (#2400, #2402). This new flag moves exited/aborted pods to the exited-garbage/garbage directory but does not delete them. A third party application can use rkt gc --mark-only=true to mark exited pods as garbage without deleting them. kvm: Add support for app capabilities limitation (#2222). By default kvm flavor has got enabled every capability inside pod. This patch adds support for a restricted set of capabilities inside a kvm flavor of rkt. stage1/init: return exit code 1 on error (#2383). On error, stage1/init was returning a non-zero value between 1 and 7. This change makes it return status code 1 only. api: Add 'CreatedAt', 'StartedAt' in pod's info returned by api service. (#2377). 文档改进 Minor documentation fixes (#2413, #2395, #2231). functional tests: Add new test with systemd-proxyd (#2257). Adds a new test and documentation how to use systemd-proxyd with rkt pods. Bug 修复 kvm: refactor volumes support (#2328). This allows users to share regular files as volumes in addition to directories. kvm: fix rkt status (#2415). Fixes a regression bug were rkt status was no longer reporting the pid of the pod when using the kvm flavor. Build actool for the build architecture (#2372). Fixes a cross compilation issue with acbuild. rkt: calculate real dataDir path (#2399). Fixes garbage collection when the data directory specified by --dir contains a symlink component. stage1/init: fix docker volume semantics (#2409). Fixes a bug in docker volume semantics when rkt runs with the option --pod-manifest. When a Docker image exposes a mount point that is not mounted by a host volume, Docker volume semantics expect the files in the directory to be available to the application. This was partially fixed in rkt 1.3.0 via #2315 but the bug remained when rkt runs with the option --pod-manifest. This is now fully fixed. rkt/image: check that discovery labels match manifest labels (#2311). store: fix multi process with multi goroutines race on db (#2391). This was a bug when multiple rkt fetch commands were executed concurrently. kvm: fix pid vs ppid usage (#2396). Fixes a bug in rkt enter in the kvm flavor causing an infinite loop. kvm: Fix connectivity issue in macvtap networks caused by macvlan NICs having incorrect names (#2181). tests: TestRktListCreatedStarted: fix timing issue causing the test to fail on slow machines (#2366). rkt/image: remove redundant quotes in an error message (#2379). prepare: Support 'ondisk' verification skip as documented by the global options (#2376). Prior to this commit, rkt prepare would check the ondisk image even if the --insecure-options=ondiskflag was provided. This corrects that. 其他更新 tests: skip TestSocketProxyd when systemd-socket-proxyd is not installed (#2436). tests: TestDockerVolumeSemantics: more tests with symlinks (#2394). rkt: Improve build shell script used in continuous integration (#2394). protobuf: generate code using a script (#2382). Generate manpages (#2373). This adds support for generating rkt man pages using make manpages and the bash completion file using make bash-completion, see the note for packagers below. tests/aws.sh: add test for Fedora 24 (#2340). Note for packagers Files generated from sources are no longer checked-in the git repository. Instead, packagers should build them: Bash completion file, generated by make bash-completion Man pages, generated by make manpages 下载地址： rkt-v1.4.0.tar.gz rkt-v1.4.0.tar.gz.sig stage1-coreos-1.4.0-linux-amd64.aci stage1-coreos-1.4.0-linux-amd64.aci.asc stage1-fly-1.4.0-linux-amd64.aci stage1-fly-1.4.0-linux-amd64.aci.asc stage1-kvm-1.4.0-linux-amd64.aci stage1-kvm-1.4.0-linux-amd64.aci.asc Source code (zip) Source code (tar.gz) rkt v1.4.0 发布，CoreOS 的容器引擎下载地址
