此页面中描述的功能标记为试验性功能,因此,在其成为通用功能之前,可能会发生更改。*这是修改后的码头堆叠与分布式应用束文件中的码头/码头-行政长官它已被更新,以准确反映较新的版本。

概述

Dockerfile 可以内置到图像中,并且可以从该图像创建容器。同样,docker-compose.yml可以将内置到分布式应用程序包中,并可以从该包创建堆栈。从这个意义上说,这个捆绑包是一个多业务可分配的图像格式。

Docker 堆栈和分布式应用程序包开始作为 Docker 1.12 和 Docker Compose 1.8 中引入的实验性功能,以及群集模式的概念以及 Engine API 中的节点和服务。Docker Engine 和 Docker Registry 都不支持 bundle 的分发,bundle的概念并不是新版本前进的重点。

但是,现在完全支持群集模式,多服务应用程序和堆栈文件。堆栈文件是特定类型的版本3撰写文件。

如果您刚刚开始使用 Docker 并希望了解部署多服务应用程序的最佳方式,那么开始的一个好地方就是入门演练。这将向您展示如何在 Compose 文件中定义服务配置,部署应用程序并使用相关的工具和命令。

生成一个包

生成捆绑的最简单方法是使用docker-compose现有的方法生成捆绑docker-compose.yml。当然,这只是一种可行的方式,同样,这docker build不是产生 Docker 镜像的唯一方法。

来自docker-compose

$ docker-compose bundle
WARNING: Unsupported key 'network_mode' in services.nsqd - ignoring
WARNING: Unsupported key 'links' in services.nsqd - ignoring
WARNING: Unsupported key 'volumes' in services.nsqd - ignoring[...]Wrote bundle to vossibility-stack.dab

从一个包创建一个堆栈

因为对堆栈和包的支持还处于试验阶段,所以需要安装一个 Docker 引擎的实验性构建才能使用它。 如果您在 Mac 或 Windows 上,请下载 “Beta通道” 版本的麦克码头或 Docker for Windows 来安装它。如果您在 Linux 上,请按照实验构建自述...

创建堆栈时,将使用docker deploy指挥:

# docker deploy --help

Usage:  docker deploy [OPTIONS] STACK

Create and update a stack

Options:      --file   string        Path to a Distributed Application Bundle file (Default: STACK.dab)      --help                 Print usage      --with-registry-auth   Send registry authentication details to Swarm agents

让我们部署前面创建的堆栈:

# docker deploy vossibility-stack
Loading bundle from vossibility-stack.dab
Creating service vossibility-stack_elasticsearch
Creating service vossibility-stack_kibana
Creating service vossibility-stack_logstash
Creating service vossibility-stack_lookupd
Creating service vossibility-stack_nsqd
Creating service vossibility-stack_vossibility-collector

我们可以验证正确创建了服务:

# docker service ls
ID            NAME                                     REPLICAS  IMAGE

管理堆栈

堆栈使用docker stack指挥:

# docker stack --help

Usage:  docker stack COMMAND

Manage Docker stacks

Options:      --help   Print usage

Commands:
  config      Print the stack configuration
  deploy      Create and update a stack
  rm          Remove the stack
  services    List the services in the stack
  tasks       List the tasks in the stack

Run 'docker stack COMMAND --help' for more information on a command.

捆绑文件格式

分布式应用程序包以 JSON 格式描述。当捆绑包作为文件保存时,文件扩展名为.dab

一个包有两个顶级域:versionservices。Docker 1.12 工具使用的版本是0.1

services在包中是构成应用程序的服务。它们对应Service于 1.12 Docker Engine API 中引入的新对象。

服务具有以下字段:

图像(必需)string服务将运行的映像。应该使用完整内容哈希来引用 Docker 映像,以完全指定服务的部署工件。示例:在服务中运行的postgres@sha256:e0a230a9f5b4e1b8b03bb3e8cf7322b0e42b7838c5c87f4545edb48f5eb8f077 Command []string命令 containers.Args []string传递给服务的参数 containers.Env  []string环境变量。map[string]string标签用于设置[]Port服务上的元数据的标签。端口服务端口(由Portint)和Protocolstring)组成。服务描述只能指定容器端口被暴露,这些端口可以根据运营商的判断映射到运行时主机上 .WorkingDir  string服务容器内的工作目录。string用户名或 UID(格式<name|uid>[:<group|gid>]:).Networks []string服务容器应该连接到的网络。部署捆绑的实体应根据需要创建网络。

::有些配置选项还不支持民建联格式,包括卷安装。
