Docker 1.7.0 發布，Linux 容器

Docker 是一個開源的應用容器引擎，讓開發者可以打包他們的應用以及依賴包到一個可移植的容器中，然后發布到任何流行的 Linux 機器上，也可以實現虛擬化。容器是完全使用沙箱機制，相互之間不會有任何接口（類似 iPhone 的 app）。幾乎沒有性能開銷,可以很容易地在機器和數據中心中運行。最重要的是,他們不依賴于任何語言、框架或包裝系統。

Runtime：

• Experimental feature: support for out-of-process volume plugins

• The userland proxy can be disabled in favor of hairpin NAT using the daemon’s --userland-proxy=false flag

• The exec command supports the -u|--user flag to specify the new process owner

• Default gateway for containers can be specified daemon-wide using the --default-gateway and --default-gateway-v6 flags

• The CPU CFS (Completely Fair Scheduler) quota can be set in docker run using --cpu-quota

• Container block IO can be controlled in docker run using--blkio-weight

• ZFS support

• The docker logs command supports a --since argument

• UTS namespace can be shared with the host with docker run --uts=host

Quality：

• Networking stack was entirely rewritten as part of the libnetwork effort

• Engine internals refactoring

• Volumes code was entirely rewritten to support the plugins effort

• Sending SIGUSR1 to a daemon will dump all goroutines stacks without exiting

Build

• Support ${variable:-value} and ${variable:+value} syntax for environment variables

• Support resource management flags --cgroup-parent, --cpu-period, --cpu-quota, --cpuset-cpus, --cpuset-mems

• git context changes with branches and directories

• The .dockerignore file support exclusion rules

Distribution

• Client support for v2 mirroring support for the official registry

Bugfixes
