How to Deploy Multiple Apps on Azure WebApps

问题:

I have two different applications which I want to deploy on the same Azure WebApp like this:

webapp.azurewebsites.net/api/ <-- run the Java REST API here
webapp.azurewebsites.net/site/ <- put the Angular2 app here

Problem

Both apps are deployed on the server but currently I'm only able to get the REST API running with a web.config like this:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
      <rules>
        <rule name="Force HTTPS" enabled="true">
          <match url="(.*)" ignoreCase="false"/>
          <conditions>
            <add input="{HTTPS}" pattern="off"/>
          </conditions>
          <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" appendQueryString="true" redirectType="Permanent"/>
        </rule>
      </rules>
    </rewrite>
    <handlers>
      <add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified"/>
    </handlers>
    <httpPlatform processPath="%JAVA_HOME%\bin\java.exe"
                  arguments="-jar D:\home\site\wwwroot\webapps\rest-api.war">
    </httpPlatform>
  </system.webServer>
</configuration>

but I'm not able to reach the Angular2 app on the server and I can't find documentation how I would configure the Java application and the Angular2 app at the same time.

I also tried to achieve this with the Virtual applications and directories settings from the Azure dashboard under Application settings - but it didn't work and I can't find a decent documentation of how I would achieve this, or if this is even possible with setting the Virtual applications and directories.

I tried to move the Angular2 site around but was not able to configure the server so that the Angular2 app is accessible while the Java application is running.

Question

Can someone point me to a good documentation on how to achieve this, or describe the deployment process in detail (with regard to the configs, e.g. the Application settings from the Azure Dashboard and the web.config file)?

回答1:

Per my experience, I think the best way for deploying multiple Apps on Azure WebApps is to set the Virtual applications and directories of Application Settings for your Azure Webapp, please see the figure below.

As reference, please refer to the answer of the SO thread Add virtual directory to existing website on Azure.

Virtual Directories are supported for Azure Websites. See Configuring Azure Websites for what you can do through the Azure Management Portal. From the Azure Portal, click on the Website and go to Configure, then scroll down to virtual applications and directories (the last config section). Just enter your virtual directory and the physical path relative to the site root and click Save.

Regarding the second part of your answer, when investigating the subject I found this blog post to be the best explanation of how the Application Settings from the dashboard interact with the Web.config file: https://azure.microsoft.com/en-us/blog/windows-azure-web-sites-how-application-strings-and-connection-strings-work/

In particular -

If the application setting(s) happen to already exist in your web.config file, Windows Azure Web Sites will automatically override them at runtime using the values associated with your website.

So the Application Settings tab in the Azure portal will take precedence over your web.config values.
