Uh oh, have you seen that before ? I bumped into an interesting issue recently when running Ansible from a RHEL derivative host. It turns out that Ansible requires the package libselinux-python to be installed on hosts where Ansible is running file modules. If you have SELinux enabled on remote nodes, you will also want to install libselinux-python on them before using any copy/file/template related functions in Ansible. https://dmsimard.com/2015/07/18/migrating-glance-images-to-a-different-backend/ Sat, 18 Jul 2015 00:00:00 +0000 https://dmsimard.com/2015/07/18/migrating-glance-images-to-a-different-backend/ The use case This isn’t exactly far-fetched but nothing seems to do it out of the box: migrate Glance images from a backend to the other. We’re in the process of moving our Glance default store to Swift, it simply scales infinitely better than the file backend. Now, changing the default store does just that: change the default store. It makes it so the newly created images will be uploaded to the new store - it doesn’t do anything for the existing images. https://dmsimard.com/2015/06/28/openstackclient-is-better-than-i-thought/ Sun, 28 Jun 2015 00:00:00 +0000 https://dmsimard.com/2015/06/28/openstackclient-is-better-than-i-thought/ When openstackclient came out, I was not a believer. I thought.. Great, a new standard (cue XKCD), and I joked about it. I had been using the ordinary CLI clients like novaclient, keystoneclient and so on. Over time, I guess I got used to their strengths, weaknesses and their quirks for better or for worse. We’ve started wrapping around Openstackclient in the different puppet modules for Openstack. Since Openstackclient provides CSV output, it makes it easy for us to parse the command outputs. https://dmsimard.com/2015/03/11/new-release-of-python-cephclient/ Wed, 11 Mar 2015 00:00:00 +0000 https://dmsimard.com/2015/03/11/new-release-of-python-cephclient/ I’ve just drafted a new release of python-cephclient on PyPi: v0.1.0.5. After learning about the ceph-rest-api I just had to do something fun with it. In fact, it’s going to become very handy for me as I might start to develop with it for things like nagios monitoring scripts. The changelog: dmsimard: Add missing dependency on the requests library Some PEP8 and code standardization cleanup Add root “PUT” methods Add mon “PUT” methods Add mds “PUT” methods Add auth “PUT” methods Donald Talton: https://dmsimard.com/2014/01/18/python-cephclient-now-on-pypi/ Sat, 18 Jan 2014 00:00:00 +0000 https://dmsimard.com/2014/01/18/python-cephclient-now-on-pypi/ Back on January 1st, I wrote about my initiative regarding a client for the Ceph REST API made in python. I’m glad to announce that the client is now available on PyPi and I have just drafted the second release: v0.1.0.2. Check it out and let me know what you think ! https://dmsimard.com/2014/01/01/a-python-client-for-ceph-rest-api/ Wed, 01 Jan 2014 00:00:00 +0000 https://dmsimard.com/2014/01/01/a-python-client-for-ceph-rest-api/ After learning there was an API for Ceph, it was clear to me that I was going to write a client to wrap around it and use it for various purposes. It is still a work in progress and I feel it is not complete and clean enough to publish on pypi yet but I invite you to take a look and tell me what you think ! The client is available on Github under the Apache v2 license here: https://github.
