deploy to server root. fixes #8

[splitbrain]

This deploys OpenGrok as the default web app in tomcat. All tomcat default apps, docs and examples have been removed from the webapps dir. A redirect from /source has been added for backward compatibility.

[tarzanek]

so if you're ok and the changes work, then let's go and merge this ...

[tarzanek]

the main deal with OpenGrok deploy are the fixes done to webapp if you have custom data roots or paths to config files, but that is given and set to default in docker, so people won't really need to change this (yet, and if they will, they will just have to fix deploy .... )

[splitbrain]

Anything that needs to be done here to get this merged or is this good to go?

[tarzanek]

let's do it ... the only thing that needs to be done is more like administration in OpenGrok and eventually getting rid of the WEBAPP variable ...

[tarzanek]

thank you @splitbrain , let's have a look then on WEBAPP variable and let's make it obsolete if all works as you say ...

[splitbrain]

Thanks for merging. Can you push it to docker hub please?

[tarzanek]

I'd hope docker hub will pick it up automatically, shouldn't it ?

[tarzanek]

it did:

Status Actions Tag Created Last Updated Success latest 2 days ago 2 days ago

so I'd hope it works (didn't test it yet)

[splitbrain]

https://hub.docker.com/r/nagui/opengrok/builds/ was last built 8 months ago. I guess I'm looking at the wrong repo? Which one is this deployed to? I guess the README needs an update?

[tarzanek]

https://hub.docker.com/r/opengrok/docker/ is the one I tied to the repo ...

so yes, README might be obsolete, sorry for that, do you mind fixing it?

[tarzanek]

I didn't most probably change it, since I didn't finish my tests :( So if the opengrok/docker repo works for you, then the README should definitely be changed ...
