Different CloudForms Catalogs for Different Groups

Posted on by

One of the largest value propositions of DevOps is the concept of Self Service provisioning. If you can remove human interaction from resource allocation, you can reduce both the response time and the likelihood of error in configuration. Red Hat CloudForms has a self service feature that allows a user to select from predefined services. You may wish to show different users different catalog items. This might be for security reasons, such as the set of credentials required and provided, or merely to reduce clutter and focus the end user on specific catalog items. Perhaps some items are still undergoing testing and are not ready for general consumption.

Obviously, these predefined services may not match your entire user population.

I’ve been working on setting up a CloudForms instance where members of different groups see different service catalogs. Here is what I did.

In Satellite server, Organization != Organization_ID

Spent a good chunk of yesterday and some of this morning stumped by a simple mistake I made.  I was trying to use our Satellite server via the Hammer command line tool to launch an instance, and kept getting and error in the content-view section.  I tried to list content views and got the same problem.  Here is a short section from my bash session.

Solutions Architect

Today is my first day at Red Hat! Well, OK, I’ve been here a few years, but today I move from Engineering to Sales. My new role is “Specialist Solutions Architect” where that specialty is Cloud.

I have a lot to learn, and I will try to use this site to record the most important and interesting details I learn.

What are the Cloud Products? well, according to Red Hat’s site, they are (please mentally prepend Red Hat to all of these) OpenStack Platform, OpenShift, CloudForms, Virtualization, Certificate System, Directory Server, as well as products bundles built out of these. Of these all, I’d guess I have the most to learn about CloudForms, as I’ve only recently started working with that. Really, though, I have a lot to learn across the board. I know that both Ansible Tower and Satellite server are major integration points for management of servers in the large, and I’ll be expected to provide expertise there as well. Plus, everything builds on the other product lines: RHEL and variants, as well as the Storage and Networking solutions.

This is going to be fun. Time to dig in.

SELinux for Kubevirt on Centos

Without disabling SELinux enforcement, an attempt to deploy a VM generates the following audit message:

type=AVC msg=audit(1504194626.938:877): avc: denied { transition } for pid=9574 comm="libvirtd" path="/usr/local/bin/qemu-system-x86_64" dev="dm-19" ino=31526884 scontext=system_u:system_r:spc_t:s0 tcontext=system_u:system_r:svirt_tcg_t:s0:c408,c741 tclass=process

Running this through audit2allow provides a little more visibility into the problem:

#============= spc_t ==============
 
#!!!! The file '/usr/local/bin/qemu-system-x86_64' is mislabeled on your system.  
#!!!! Fix with $ restorecon -R -v /usr/local/bin/qemu-system-x86_64
allow spc_t svirt_tcg_t:process transition;

This is probably due to running as much of the virtualization machinery in containers. /usr/local/bin/qemu-system-x86_64 comes from inside the libvirt container. It does not exist on the base OS filesystem. Thus, just running restorecon won’t do much.
