Re: [xcat-user] Using online repos with xCAT

Hi Kevin,
 
Now we do not have such support, sorry for inconvenience, one possible solution is you can leverage `postinstall` attribute to inject the scripts to compose additional yum config files, RHN certificates and invoke yum commands to install/update packages from RHN. We will consider this feature request, but cannot promise its priority or date....
 
or if you would like to complete some mechanism to support this, it will be much appreciated if you can create a PR on this
 
 
best regards

Thank you so much for point out that pkgdir can also take a repository URL! That will turn out ot be invaluable in our situation, once I get it to work.
 
My next question is whether there is a way to inject a setting into the yum configuration file that genimage uses? We are a RedHat shop and have enough RedHat subscriptions for all our nodes, of course. We keep our yum repository on a Satellite server. But that only works with the configuration in /etc/yum.repos.d, not with the transient one one that genimage generates on the fly in /tmp. The actual problem is that the yum repository is protected with a client certificate, which has to be added to the repository.

for redhat diskless osimage, we do support online repo in pkgdir, for example, 
`chdef -t osimage  -o myosimage -p pkgdir=http://rh.com/updates`

Hi Kevin,
 
xCAT can support multiple OS update repo on local, you just need set multiple repo directories for pkgdir attribute of osimage
 
So beside the local OS repo created by copycd,  you can use other way (for example, reposync) to create local OS update repository, and update your osimage to use it.

For us, the size of the local repos is not an issue - we already have local repos anyway, and use RedHat's Satellite server to manage them. Compounding this, we use stateless nodes, so every reboot would re-download a lot of RPMs.
 
Building images with genimage the standard xCAT way ends up with horrendously outdated software (and in at least one case, we ran into version incompatibilities)..
 
I'm currently working on a "cobbled-together" way to build a local repo to replace the one xCAT uses, but I'd much prefer to have it officially supported by xCAT.

Hi Kilian,

have you compared download sizes for repos vs. having each node go online? In my experience, repos contain WAY more packages than are actually installed on cluster nodes. Saving bandwidth only works with a reasonably high number of nodes of the same architecture. Delta packages, if available, help to even further reduce bandwidth. As does a proxy tailored to your needs.

Controlling versions is easier though with local repos. Could also be done with config mgmt, and more flexible so. But local repos are the easy way for sure.

Mit freundlichen Grüßen / Best regards

We usually do it by either mirroring those repositories on the management node (which is good to make sure all the nodes get the same version of the repo at any given time, and to save bandwidth), or by adding online repositories on the nodes in postscripts.
