安装和运行文本分析容器Install and run Text Analytics containers

容器使你能够在自己的环境中运行文本分析 Api, 这非常适合你的特定安全和数据管理要求。Containers enable you to run the Text Analytic APIs in your own environment and are great for your specific security and data governance requirements. 文本分析容器提供对原始文本的高级自然语言处理, 并包括三个主要功能: 情绪分析、关键短语提取和语言检测。The Text Analytics containers provide advanced natural language processing over raw text, and include three main functions: sentiment analysis, key phrase extraction, and language detection. 容器当前不支持实体链接。Entity linking is not currently supported in a container.

如果没有 Azure 订阅,请在开始之前创建一个免费帐户If you don't have an Azure subscription, create a free account before you begin.


若要运行任何文本分析容器, 你必须拥有主机计算机和容器环境。To run any of the Text Analytics containers, you must have the host computer and container environments.


使用文本分析容器之前,必须满足以下先决条件:You must meet the following prerequisites before using Text Analytics containers:

必填Required 用途Purpose
Docker 引擎Docker Engine 需要在主计算机上安装 Docker 引擎。You need the Docker Engine installed on a host computer. Docker 提供用于在 macOSWindowsLinux 上配置 Docker 环境的包。Docker provides packages that configure the Docker environment on macOS, Windows, and Linux. 有关 Docker 和容器的基础知识,请参阅 Docker 概述For a primer on Docker and container basics, see the Docker overview.

必须将 Docker 配置为允许容器连接 Azure 并向其发送账单数据。Docker must be configured to allow the containers to connect with and send billing data to Azure.

在 Windows 上,还必须将 Docker 配置为支持 Linux 容器。On Windows, Docker must also be configured to support Linux containers.

熟悉 DockerFamiliarity with Docker 应对 Docker 概念有基本的了解,例如注册表、存储库、容器和容器映像,以及基本的 docker 命令的知识。You should have a basic understanding of Docker concepts, like registries, repositories, containers, and container images, as well as knowledge of basic docker commands.
文本分析资源Text Analytics resource 若要使用容器,必须具有:In order to use the container, you must have:

用于获取关联的 API 密钥和终结点 URI 的 Azure文本分析资源An Azure Text Analytics resource to get the associated API key and endpoint URI. 这两个值可以从 Azure 门户中的“文本分析概述”和“密钥”页面获得,并且是启动容器时所必需的。Both values are available on the Azure portal's Text Analytics Overview and Keys pages and are required to start the container.

{API_KEY} :"密钥" 页上有两个可用的资源键之一{API_KEY}: One of the two available resource keys on the Keys page

{ENDPOINT_URI} :"概述" 页中提供的终结点{ENDPOINT_URI}: The endpoint as provided on the Overview page

正在收集所需参数Gathering required parameters

所有认知服务容器都需要三个主要参数。There are three primary parameters for all Cognitive Services' containers that are required. 最终用户许可协议 (EULA) 的值accept必须为。The end-user license agreement (EULA) must be present with a value of accept. 此外, 需要终结点 URL 和 API 密钥。Additionally, both an Endpoint URL and API Key are needed.

终结点 URI{Endpoint_URI}Endpoint URI {Endpoint_URI}

"终结点URI" 值在相应认知服务资源的 "Azure 门户概述" 页上可用。The Endpoint URI value is available on the Azure portal Overview page of the corresponding Cognitive Service resource. 导航到 "概述" 页, 将鼠标悬停在终结点Copy to clipboard上, 将显示一个图标。Navigate to the Overview page, hover over the Endpoint, and a Copy to clipboard icon will appear. 复制并在需要时使用。Copy and use where needed.

收集终结点 uri 供以后使用

{API_Key}Keys {API_Key}

此密钥用于启动容器, 并在相应认知服务资源的 Azure 门户 "密钥" 页上可用。This key is used to start the container, and is available on the Azure portal's Keys page of the corresponding Cognitive Service resource. 导航到 "密钥" 页, 然后单击Copy to clipboard 图标。Navigate to the Keys page, and click on the Copy to clipboard icon.



这些订阅密钥用于访问认知服务 API。These subscription keys are used to access your Cognitive Service API. 不要共享你的密钥。Do not share your keys. 安全地存储它们, 例如, 使用 Azure Key Vault。Store them securely, for example, using Azure Key Vault. 我们还建议定期重新生成这些密钥。We also recommend regenerating these keys regularly. 只需一个密钥就能进行 API 调用。Only one key is necessary to make an API call. 重新生成第一个密钥时, 可以使用第二个密钥来继续访问该服务。When regenerating the first key, you can use the second key for continued access to the service.

如何使用容器How to use the container

一旦容器位于主计算机上,请通过以下过程使用容器。Once the container is on the host computer, use the following process to work with the container.

  1. 使用所需的计费设置运行容器Run the container, with the required billing settings. 提供 docker run 命令的多个示例More examples of the docker run command are available.
  2. 查询容器的预测终结点Query the container's prediction endpoint.

通过 docker run 运行容器Run the container with docker run

使用 docker run 命令运行三个容器中的任意一个。Use the docker run command to run any of the three containers. 有关如何获取{Endpoint_URI}{API_Key}值的详细信息, 请参阅收集必需的参数Refer to Gathering required parameters for details on how to get the {Endpoint_URI} and {API_Key} values.

可用的命令示例 docker runExamples of the docker run command are available.

Docker run 命令的运行容器示例Run container example of docker run command

docker run --rm -it -p 5000:5000 --memory 4g --cpus 1 \
mcr.microsoft.com/azure-cognitive-services/keyphrase \
Eula=accept \
Billing={ENDPOINT_URI} \

此命令:This command:

  • 从容器映像运行关键短语容器Runs a key phrase container from the container image
  • 分配一个 CPU 核心和 4 GB 内存Allocates one CPU core and 4 gigabytes (GB) of memory
  • 公开 TCP 端口 5000,并为容器分配伪 TTYExposes TCP port 5000 and allocates a pseudo-TTY for the container
  • 退出后自动删除容器。Automatically removes the container after it exits. 容器映像在主计算机上仍然可用。The container image is still available on the host computer.


必须指定 EulaBillingApiKey 选项运行容器;否则,该容器不会启动。The Eula, Billing, and ApiKey options must be specified to run the container; otherwise, the container won't start. 有关详细信息,请参阅计费For more information, see Billing.

在同一主机上运行多个容器Run multiple containers on the same host

若要使用公开端口运行多个容器,请确保在运行每个容器时使用不同的公开端口。If you intend to run multiple containers with exposed ports, make sure to run each container with a different exposed port. 例如,在端口 5000 上运行第一个容器,在端口 5001 上运行第二个容器。For example, run the first container on port 5000 and the second container on port 5001.

可以让此容器和其他 Azure 认知服务容器一起运行在该主机上。You can have this container and a different Azure Cognitive Services container running on the HOST together. 此外,还可以让同一认知服务容器的多个容器一起运行。You also can have multiple containers of the same Cognitive Services container running.

查询容器的预测终结点Query the container's prediction endpoint

容器提供了基于 REST 的查询预测终结点 API。The container provides REST-based query prediction endpoint APIs.

使用主机 http://localhost:5000,以获得容器 API。Use the host, http://localhost:5000, for container APIs.

验证容器是否正在运行Validate that a container is running

有几种方法可用于验证容器是否正在运行。There are several ways to validate that the container is running.

请求Request 目的Purpose
http://localhost:5000/ 容器提供主页。The container provides a home page.
http://localhost:5000/status 使用 GET 进行了请求,从而在不会导致终结点查询的情况下验证容器是否正在运行。Requested with GET, to validate that the container is running without causing an endpoint query. 此请求可用于 Kubernetes 运行情况和就绪情况探测This request can be used for Kubernetes liveness and readiness probes.
http://localhost:5000/swagger 容器提供终结点以及 Try it now 功能的整套文档。The container provides a full set of documentation for the endpoints and a Try it now feature. 使用此功能可以将设置输入到基于 Web 的 HTML 表单并进行查询,而无需编写任何代码。With this feature, you can enter your settings into a web-based HTML form and make the query without having to write any code. 查询返回后,将提供示例 CURL 命令,用于演示所需的 HTTP 标头和正文格式。After the query returns, an example CURL command is provided to demonstrate the HTTP headers and body format that's required.


停止容器Stop the container

若要关闭的情况下该容器,其中容器正在运行,在命令行环境中选择Ctrl + CTo shut down the container, in the command-line environment where the container is running, select Ctrl+C.


如果运行启用了输出装入点和日志记录的容器,该容器会生成有助于排查启动或运行容器时发生的问题的日志文件。If you run the container with an output mount and logging enabled, the container generates log files that are helpful to troubleshoot issues that happen while starting or running the container.


文本分析容器使用 Azure 帐户中的_文本分析_资源向 Azure 发送账单信息。The Text Analytics containers send billing information to Azure, using a Text Analytics resource on your Azure account.

对该容器的查询在用于 <ApiKey> 的 Azure 资源的定价层计费。Queries to the container are billed at the pricing tier of the Azure resource that's used for the <ApiKey>.

如果未连接到计费终结点进行计量,则 Azure 认知服务容器不会被许可运行。Azure Cognitive Services containers aren't licensed to run without being connected to the billing endpoint for metering. 必须始终让容器可以向计费终结点传送计费信息。You must enable the containers to communicate billing information with the billing endpoint at all times. 认知服务容器不会将客户数据(例如,正在分析的图像或文本)发送给 Microsoft。Cognitive Services containers don't send customer data, such as the image or text that's being analyzed, to Microsoft.

连接到 AzureConnect to Azure

容器需要计费参数值才能运行。The container needs the billing argument values to run. 这些值使容器可以连接到计费终结点。These values allow the container to connect to the billing endpoint. 容器约每 10 到 15 分钟报告一次使用情况。The container reports usage about every 10 to 15 minutes. 如果容器未在允许的时间范围内连接到 Azure,容器将继续运行,但不会为查询提供服务,直到计费终结点恢复。If the container doesn't connect to Azure within the allowed time window, the container continues to run but doesn't serve queries until the billing endpoint is restored. 尝试连接按 10 到 15 分钟的相同时间间隔进行 10 次。The connection is attempted 10 times at the same time interval of 10 to 15 minutes. 如果无法在 10 次尝试内连接到计费终结点,容器将停止运行。If it can't connect to the billing endpoint within the 10 tries, the container stops running.

计费参数Billing arguments

必须使用有效值指定所有以下三个选项,才能使 docker run 命令启动容器:For the docker run command to start the container, all three of the following options must be specified with valid values:

OptionOption 描述Description
ApiKey 用于跟踪计费信息的认知服务资源的 API 密钥。The API key of the Cognitive Services resource that's used to track billing information.
必须将此选项的值设置为 Billing 中指定的已预配资源的 API 密钥。The value of this option must be set to an API key for the provisioned resource that's specified in Billing.
Billing 用于跟踪计费信息的认知服务资源的终结点。The endpoint of the Cognitive Services resource that's used to track billing information.
必须将此选项的值设置为已预配的 Azure 资源的终结点 URI。The value of this option must be set to the endpoint URI of a provisioned Azure resource.
Eula 表示已接受容器的许可条款。Indicates that you accepted the license for the container.
此选项的值必须设置为 acceptThe value of this option must be set to accept.
