[Rdo-list] [OFI] Speeding up OFI provisioning in Dev env

[Martyn Taylor]

If you are like me and you have a dog slow connection and you are 
wanting to test orchestration on using Staypuft, it can take forever and 
a day.  The main issue for me was that the network installs were taking 
hours, if you are using Fedora etc... you can quite easily use a proxy 
like Squid to cache everything.  However, I am using RHEL which is 
usually behind SSL.  It's not impossible to get round this with squid, 
but you'll need to play around with man in the middle stuff.

One quick and easy way to speed up network install for RHEL and any 
other distro, is just to download the DVD iso, mount it, then service it 
up via apache.  You'll still need to do some public traffic as you'lll 
need to download all the OpenStack modules etc... but this has taken 
provision time of a host for me from about 90 mins to about 15mins.  
Since we are provisioning sequentially that makes a massive difference.

Here are the steps involved:

*1. Add a entry in /etc/hosts for your virtual host:*

192.168.100.1 mirrors.local

*2. create a new virtual host file, /etc/httpd/conf.d/06-local-mirrors.conf*

<VirtualHost  mirrors.local:80>
   ServerName mirrors.local

   DocumentRoot /var/www/html/repos
</VirtualHost>

<Directory "/var/www/html/repos">
     Options +Indexes
</Directory>

*3. Download the your ISO of choice and mount it somewhere:*

mkdir /mnt/rhel-iso
mount -o loop <ISO> /mnt/rhel-iso
*
**4. Create symlink to the ISO*

mkdir /var/www/html/repos
ln -s /mnt/rhel-iso /var/www/html/repos

*5. Add your new install media in foreman as normal, adding the URL to 
your ISO*
