在 azure 应用服务中使用 docker-compose

Question

我让我的平均堆栈代码在 docker-compose 配置中工作。如果我docker-compose up在我的电脑上运行，那么我可以成功登录到我的应用程序localhost如果转到应用程序服务并单击 docker-compose 预览选项并上传我的 docker-compose.yml 文件。部署后，当我单击该应用程序的 URL 时，出现应用程序错误，但不知道为什么。也许我必须更改文件中的某些内容才能使其在不同的环境中工作？我感谢任何帮助！

我在某处读到，如果在同一订阅中使用 ACR，则不必提供用户名、密码或 URL 详细信息，确实如此。因此，如果是这种情况，则身份验证不是问题。

前端 docker 镜像和后端 docker 镜像位于 azure 容器注册表中。当我在应用服务中设置 docker 时，我指向注册表 来自 azure 的 docker 日志说

前端 Dockerfile

EXPOSE 3000

CMD ["npm", "run", "start"]

docker-compose.yml

version: '3'
services:
    backend:
        build: ./backend
        ports:
            - "3000:3000"
    frontend:

Answer 1

对于这个问题，问题在于buildAzure App Service中不支持的docker-compose的属性。您可以在Docker Compose options 中获取有关支持选项的更多详细信息。

因此，您的解决方案是自己在本地创建映像，然后将它们推送到 docker 注册表，例如 Azure 容器注册表。最后，你需要改变build成image。然后将其部署到 Azure 应用服务，它会正常工作。

Another approach would be to use the more recent (Oct. 2020) compose-cli, which is made to run both locally, and in the context of a Microsoft ACI (Azure Container Instance).

Example: "Deploying a Minecraft Docker Server to the cloud" from Guillaume Tardif (Senior Software Engineer @ Docker)

The command to start this locally is now much simpler:

$ docker-compose --project-name mc up

And to deploy to ACI, still using the ACI context I created previously:

$ docker compose --project-name mc2 up 

See also "How To Deploy Containers to Azure ACI using Docker CLI and Compose" from Peter McKee (Coding Adventures.io).

You can easily create your ACI-complient context:

docker context create aci myaci
docker-compose push
docker context use myaci
docker compose up
