todo.txt done

Posted on by

While I like the functionality of the todo.txt structure, I do not like the fact that done tasks stay in my todo list in perpetuity, and I also don’t want to lose them.  So, I’ve made a simple hack that allows me to move done items to a done folder.  Here’s the code:

#!/bin/sh
awk '/^x/ {print $0}' ~/Dropbox/todo/todo.txt >> ~/Dropbox/todo/done.txt 
awk '!/^x/ {print $0}' ~/Dropbox/todo/todo.txt > ~/Dropbox/todo/todo2.txt
mv ~/Dropbox/todo/todo2.txt ~/Dropbox/todo/todo.txt

 

I call it todo_done.sh.

I copied my original to /tmp/pre in order to test and make sure I have a backup.  After running todo_done.sh I get:

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.

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.
