问题描述

我正在尝试建立一个通过文件共享到存储帐户具有持久性存储的Web应用.

I'm trying to set up a web app that has persistent storage via file share to a storage account.

我正在遵循Microsoft文档中的各种指南，而我设法做到了大部分，我的应用程序具有持久存储能力.但是现在，我想做的是，我想将卷映射到我的存储帐户.

I'm following various guides from Microsoft docs and I managed to do most of it, my app has persisted storage. But now, what I wanna do, I want to map volumes to my storage account.

我看到有一个可以在docker-compose中使用的变量 $ {WEBAPP_STORAGE_HOME} .

I saw that there is this variable ${WEBAPP_STORAGE_HOME} that I can use in my docker-compose.

我的问题是，此变量的值是多少?文档状态:

My question is, what is the value of this variable? The docs state:

我觉得这有点模糊.它知道自动映射我的路径映射吗?如果我有多个路径映射该怎么办?是否应该在 Configuration 刀片中的应用程序设置"中设置值?如果是这样，我需要指定什么安装路径?

I find this a little vague. Does it know automatically to map my path mappings? What if I have multiple path mappings? Should I set the value in the App Settings in the Configuration blade? If so, what do I need to specify, the mount path?

除此之外，我看到它的用法如下:

Besides that, I saw that it is used as following:

version: '3.3'

services:
   wordpress:
     image: mcr.microsoft.com/azuredocs/multicontainerwordpress
     volumes:
      - ${WEBAPP_STORAGE_HOME}/site/wwwroot:/var/www/html
     ports:
       - "8000:80"
     restart: always

我在docker-compose中使用了命名卷.我认为没有必要指定类似的内容吗?

I'm used with named volumes in docker-compose. I figure there is no need to specify something like that?

更新在@Jason Pan回答之后，我尝试了一下坐骑.

UPDATEAfter @Jason Pan's answer, I tried to play with the mount a little bit.

我成功通过以下docker-compose在App Service上进行了持久存储:

I succeeded in having persisted storage on the App Service with the following docker-compose:

# ... lines skipped for brevity
    volumes:
      - mysql-data:/var/lib/mysql

volumes:
  mysql-data:
    driver: local

但是我想将数据保留在存储帐户中.我看到可以通过以下方式实现: AppService/Configuration/Path Mappings .

But I want to persist the data on a Storage Account. I saw that this is possible via: AppService/Configuration/Path Mappings.

我的Docker Compose

My Docker Compose

# ...
    volumes:
      - MyMountedPath:/var/lib/mysql

在这个docker-compose文件中，我有我的应用和一个MySQL映像:确切地说，是 mysql:8 .

In this docker-compose file, I have my app and a MySQL image: mysql:8 to be exact.

我安装了一条路径，如下所示:名称:MyMountedPath;挂载路径:/usr/local/mysql;类型:Azure文件... .

I mounted a path as follows:Name: MyMountedPath; Mounted Path: /usr/local/mysql; Type: Azure Files ....

我在日志中收到以下错误:

And I get the following error in the logs:

由于它可以与第一种方法一起使用，因此我怀疑路径映射的定义方式存在一些问题.这使我提出了更多问题:

Since it worked with the first approach, I suspect that there are some issues with the way my Path mapping is defined. This led me to even more questions:

我的挂载路径是否需要存在于App Service文件系统上?如果没有，我可以定义以下内容:/foo/bar 吗?
如果我的挂载路径名为 MyMountedPath ，我可以在docker-compose文件中指定类似的内容

吗?

Does my Mount Path need to exist on the App Service File system? If no, can I define something like: /foo/bar ?
If I have a Mount Path name MyMountedPath, can I specify in the docker-compose file something like

volumes:
  - MyMountedPath/foo:/something

基本上是在安装的路径中导航吗?

Basically, navigating in the mounted path?

是否需要在存储帐户的文件存储中挂载此路径?还是在需要存储内容时App Service会创建此路径?
