LXD 0.9发布,Linux容器工具,LXC技术重构

LXD 是 ubuntu 基于 LXC 技术的重构，容器天然支持非特权和分布式。

LXD 与 Docker 的思路不同，Docker 是 PAAS，LXD 是 IAAS。

LXD 包括三个组件：

• 系统范围的守护进程 (lxd)

• 命令行客户端 (lxc)

• OpenStack Nova 插件 (nova-compute-lxd)

主要特性：

• 直观 (简洁的 API 和快速的命令行体验)

• 基于镜像

• 在线迁移

LXD 0.9 发布，此版本主要改进如下：

• Fixed memory and file descriptior leaks (and add extra tests for those)

• Fallback to chmod when setfacl fails (filesystem without ACLs support)

• Fixed container logging and make it available through lxc info (--show-log)

• Setup the right uid/gid map for privileged containers

• Report invalid configuration in "lxc config edit" and "lxc profile edit"

• Improved the first use experience and the profile/config examples

• Rename "lxc config profile *" to "lxc profile *" (old syntax is still supported)

• More reliable database handling

• Container copies get a new MAC address

• USER is now set in the container environment (on exec)

• Track the image used to build the container and use this to optimize copy/migration

• Improved database testing

• Fixed pts device owneship on exec

• Fixed raw.lxc being applied too early (resulted in broken lxc.network.script and others)

• Better argument parsing in both lxc and lxd

• Improved performance in container and network listing

• Fixed certificate name conflicts in the trust database
