Dear Yfried,

Please provide steps for accessing horizon UI from web browser after overcloud deployment completed. Thanks in advance.

Hi, Here are the manual steps, I will add them to the playbooks shortly:

1. Get the overcloud floating IP from undercloud:/home/stack/overcloudrc

   [stack@undercloud-0 ~]$ cat overcloudrc
   # Clear any old environment that may conflict.
   for key in $( set | awk '{FS="="}  /^OS_/ {print $1}' ); do unset $key ; done
   export OS_NO_CACHE=True
   export OS_CLOUDNAME=overcloud
   export OS_AUTH_URL=http://10.0.0.109:5000/v2.0
   export NOVA_VERSION=1.1
   export COMPUTE_API_VERSION=1.1
   export OS_USERNAME=admin
   export OS_PASSWORD=FOO
   export no_proxy=,10.0.0.109,192.168.24.7
   export OS_PROJECT_NAME=admin
   export PYTHONWARNINGS="ignore:Certificate has no, ignore:A true SSLContext object is not available"

2. Create a forward rule in hypervisor's iptables, that will send all incoming HTTP traffic to the overcloud's entrypoint

iptables -t nat -A PREROUTING -d 10.35.64.55/32 -p tcp -m tcp --dport 8080 -j DNAT --to-destination 10.0.0.109:80

Note: If --overcloud-ssl is set to "yes" (or OS_AUTH_URL starts with "https"), you need to make sure the destination port is 443 and not 80

3. flush all existing iptable rules: because virt-net disables forwarding by default. working on a solution for this:

iptables -F

4. Access your hypervisor via browser in port 8080: http://10.35.64.55:8080
