DNS configuration with Cloud Foundry

[Guido Davide Dall'Olio]

Hi guys. Sorry to bother, again me!
This is my deployment file: http://pastebin.com/SBy7Lin4
it's working (unbelievable) !

But CloudFoundry is only partially working.

I can set "cf target http://ccng.cf.my.cloud"
I can create space, org, but when I try to push an app I get this error:

cf push

Using manifest file manifest.yml

Creating hello... OK

1: cf.my.cloud

2: none

Domain> cf.my.cloud

Creating route hello.cf.my.cloud... OK

Binding hello.cf.my.cloud to hello... OK

Uploading hello... OK

Preparing to start hello... OK

I think the manifest file should be ok. But I'm not complete sure...
Probably my DNS configuration is not correct or is not correct domain configuration in deployment file. It's my first time using a DNS server.

I set up a VM with only DNS server running, its ip is 10.1.0.3. All VMs running in my OpenStack have /etc/resolv.conf with 10.1.0.3 and 8.8.8.8 nameservers.
All machine can reach internet and ping 10.1.0.3 (DNS server), host server too.
Now, I don't know if my problem is DNS related.

From deployment file you can see cloudfoundry router is on 10.1.0.20 machine.

This is my DNS configuration:
/etc/bind/named.conf.local

# Our forward zone

zone "my.cloud" {

type master;

file "/etc/bind/zones/db.my.cloud";

};

zone "0.1.10.in-addr.arpa" {

type master;

file "/etc/bind/zones/db.10";

};

/etc/bind/zones/db.my.cloud Here I set a wildcard for *.cf.my.cloud , pointing to router VM right?

        dnssec-validation auto;

        auth-nxdomain no;    # conform to RFC1035

        listen-on-v6 { any; };

};

Now
if I nslookup, dig, host http://ccng.cf.my.cloud from VMs and host machine
I always obtain 10.1.0.20 ip (router VM) -> correct right?

BUT if I ping http://ccng.cf.my.cloud I get a "unknown host" !!!

BUT cf target http://ccng.cf.my.cloud answers me with OK and I can login!

BUT if I "nmap -p 80 http://ccng.cf.my.cloud" I get a "PORT   STATE SERVICE 80/tcp open  http"

Where's the problem?
Any help is really really appreciated...I think I'm really close to get a working CF on my OpenStack :D

[Guido Davide Dall'Olio]

OK, probably I'm missing this

directory_server_protocol: http

Under DEA. Let me just re-deploy.

[Guido Davide Dall'Olio]

It was that flag.

CF works!!!!!

DNS is correct!

YEAH
