Deployment question

[Tim Uckun]

Hi All.

I know very little about tomcat so I hope this question is not too naive.

I see that there are some erb templates to generate some yaml and xml files but I see no deployment scripts or rake tasks to generate those files and push them to the server.

Also do I need to separately put the context.xml on the tomcat server?  I presume there is a context.xml for every app so why isn't there a place to put in app itself?

Thanks.

When you download the war file you get everything bundled, including all the erb templates.

context.xml is the place in tomcat where you define the external properties to pass to the application. Typically this is things like the JDBC connection, mail server and other properties the application needs. It is convenient because the war file is then completely replacable. Upgrade the application by just replacing the war file and touching nothing else.

If I create my own war  file does tomcat know to pick up the config.xml from the config directory or do I have to put it in place manually?

Also when do the migrations run? I could not see any command which triggers the migrations.

context.xml normally goes into the conf directory in tomcat

The code sorts that out automatically when the app is first launched.

Again please excuse my ignorance....

Does it get put there by tomcat from the war file or do I put it there myself.  Also is there one context.xml for the entire server or one per app?

Thanks.

Tomcat deployment is mostly quite simple. You run the tomcat application (the installer package will put a startup script in the right place on your platform). You edit the files in the conf directory. Think of context.xml as a way to pass parameters to the applications. There are other config files like server.xml but mostly you can leave them alone.

Then just drop the war files into the webapps folder. The name of the war file is important by default (although this can be edited in the config). So an application called myapp.war will result in tomcat sending any requests which start with /myapp/ to that application. An application called ROOT.war is a special case and will get all requests not otherwise directed to another app.

So let's say you have:

webapps
- manager.war
- ROOT.war

The manager app gets all requests to /manager/ and the ROOT app gets everything else.

How do I get it to respond to myapp.mydomain.com rather than mydomain.com/myapp 

Do I have to have nginx or something in front of it?

[Vikrant Chaudhary]

You'll have to configure your web-server to point myapp.mydomain.com
to the deployed war.
