Unable to deploy migrated Vaadin 14 app to Azure

Flow
1

I’ve fully migrated my app to Vaadin 14, using polymer and all. The app runs correctly when started in Eclipse from the pom. But when I create a WAR file and deploy that to Azure, it fails. Since it is on the Azure cloud, I have a hard time determining what is going on. But I do notice that the node_modules are not in the war file, which I kinda assume they need be?

Azure works with Vaadin 14. Have a look at geocaching.blafoo.de

Did you create the WAR file with

mvn clean package -Pproduction

I used to deploy using the Eclipse Vaadin plugin. That works for Vaadin 10, but not for 14. I assume the cause is the missing polymer things. I’ve build using mvn package (as you suggest), and deployed locally on a Tomcat 8.5. That works, so the war is ok now. Next I have to figure out how to do the upload; curl and the azure CLI command are not working yet. To be continued…

Deploying to Azure is a bit tricky. Personally, i find the Azure Eclipse Plugin the most easiest way to deploy.

And, i changed the pom.xml this way

 <profiles>
        <profile>
            <!-- Production mode is activated using -Pproduction -->
            <id>production</id>
            <properties>
                <vaadin.productionMode>true</vaadin.productionMode>
            </properties>
            <activation>
            	<activeByDefault>true</activeByDefault>
           	</activation>

That is how I build the war file as well, always production mode. Of course using the flag is better, but right now I’m in the “whatever works” mode.

So this worked:

  • build using maven with production profile
  • create user creditials in the deployment center → FTP section
  • upload war file using curl using the user credentials
