如何在 Azure Web App 中为容器安装 docker 卷? [英] How to mount docker volume in Azure Web App for containers?

问题描述

我正在尝试在 Azure 应用服务中运行 KrakenD 映像.

KrakenD 需要将 json 配置文件 krakend.json 放入/etc/krakend/(KrakenD 镜像基于 Linux Alpine)

我使用以下 docker-compose 文件为容器创建了 Web 应用程序:

版本:3"服务:克拉肯德:图片:devopsfaith/krakend:最新卷:- ${WEBAPP_STORAGE_HOME}/site/krakend:/etc/krakend端口:- 8080:8080"重启:总是

添加了带有 blob 容器的存储帐户，其中上传了示例 kraken.json 文件

在应用程序配置中，我添加了这样的路径映射:

但是看起来卷没有正确安装

2019-11-15 12:46:29.369 错误 - 多容器单元未启动成功

其他问题

1. 存储挂载中的挂载路径是什么意思?- 我把价值放在那里 /krankend

2. 卷定义以 ${WEBAPP_STORAGE_HOME} 开头

   I'm trying to run KrakenD image in Azure App Service.

   KrakenD requires json config file krakend.json to be put into /etc/krakend/ (KrakenD image is based on Linux Alpine)

   I created Web App for containers with the following docker-compose file:

   version: "3"
   services:
     krakend:
       image: devopsfaith/krakend:latest
       volumes:
         - ${WEBAPP_STORAGE_HOME}/site/krakend:/etc/krakend
       ports:
         - "8080:8080"
       restart: always
   

   Added storage account with a blob container where uploaded sample kraken.json file

   In app configuration i added a path mapping like this:

   But it looks like volume was not mounted correctly

   2019-11-15 12:46:29.368 ERROR - Container create failed for krakend_krakend_0_3032a936 with System.AggregateException, One or more errors occurred. (Docker API responded with status code=InternalServerError, response={"message":"invalid volume specification: ':/etc/krakend'"} ) (Docker API responded with status code=InternalServerError, response={"message":"invalid volume specification: ':/etc/krakend'"} ) InnerException: Docker.DotNet.DockerApiException, Docker API responded with status code=InternalServerError, response={"message":"invalid volume specification: ':/etc/krakend'"}

   2019-11-15 12:46:29.369 ERROR - multi-container unit was not started successfully

   Additional questions

   1. What does mean Mount path in Storage mounting? - i put there value /krankend

   2. volume definition starts with ${WEBAPP_STORAGE_HOME} in docs they specified it as

      volumes: - ${WEBAPP_STORAGE_HOME}/site/wwwroot:/var/www/html

   so i did it by analogy and tried all 3 possible paths

   ${WEBAPP_STORAGE_HOME}/site/wwwroot/krakend
   ${WEBAPP_STORAGE_HOME}/site/krakend
   ${WEBAPP_STORAGE_HOME}/krakend
   

   but no luck - still getting the error

   ERROR parsing the configuration file: '/etc/krakend/krakend.json' (open): no such file or directory

   解决方案

   finally resolved that with the following docker-compose file

   version: "3"
   services:
     krakend:
       image: devopsfaith/krakend:latest
       volumes:
         - volume1:/etc/krakend
       environment:
        WEBSITES_ENABLE_APP_SERVICE_STORAGE: TRUE
       ports:
         - "8080:8080"
       restart: always
   

   where volume1 is a blob storage mounted as the following
