Yesterday, virt-bootstrap came to life. This tool aims at simplifying the creation of root file systems for use with libvirt’s LXC container drivers. I started prototyping it a few months ago and Radostin Stoyanov wonderfully took it over during this year’s Google Summer of Code.
Or you can use libguestfs to write files directly into the disk image (for instance using virt-copy-in) — but make sure you only use libguestfs when the VM is not running, or you will get disk corruption. The installation has an SSH client, so one easy way to get files in and out is to use “scp” from inside the VM to talk to an SSH server outside it.
In case you’re a programmer, learning a new programming language helps you expand your career opportunities. Learning new skills can be helpful if you are looking to change careers. One also needs to have the knowledge of top programming languages to make correct choices. In case you end up learning a skill that’s in heavy demand, it turns out to be something that brings immense benefits and stay with you lifelong.
While it would be possible to publish a completed virtual machine you could download and click to run, understanding the underpinnings of the most basic installation and configuration of devstack will provide an appreciation of the complexity of the product and the software development capabilities. There are some hardware requirements and various copy/paste command line instructions on a Linux virtual machine.
Suppose that you have a RDO/Openstack cloud already in place, but that you’d want to automate some operations : what can you do. It’s particulary true for our CI environment where we run “agentless” so all configuration changes happen through Ansible. On my side, I already mentioned that I used puppet to deploy initial clouds, but I still prefer Ansible myself when having to launch ad-hoc tasks, or even change configuration[s].
I’ve stuck mostly with twitter and only the occasional blog post, usually on someone else’s platform. They’ve gotten me to the point where I’m starting to feel a little guilty about being a digital vagrantand so here we are. For the last few years, I’ve not really cared at all about a semi-permanent slice of home on the internet. A few folks like Ben Cotton have tried to reform me.
OneView for Red Hat Enterprise Virtualization: Unpack and install the downloaded package. A third-party download manager or a browser with an embedded download manager (like. OneView for Microsoft System Center DVD: Once you have the DVD ISO image, you can either.
Python is very simple to learn when compared to some other languages out there, but yet, it’s still very powerful, and is one of the most widely used languages for some programs and websites you may not even know used it, such as:. Python is one of the most amazing languages one can learn to code.
Especially due to Apple embracing the format there is a lot of files out there using it and thus we wanted to support it in Fedora too. AAC stands for Advanced Audio Coding and was created by the MPEG working group as the successor to mp3. For those not well versed in the arcane lore of audio codecs AAC is the codec used for things like iTunes and is found in a lot of general media files online.
The CFP is now open, if you’re interested in presenting. The CFP closes October 30th. Meanwhile, we’re also planning a Dojo in Brussels, on the Friday before FOSDEM, as we’ve been doing this for a number of years now. We’re looking for any talks about work that you’re doing on CentOS, or anything that you’re doing using CentOS.
You have defined DBA and user credentials ACL’s across dev, test and prod environments. How long as a operator does it take to acquire the software, install, configure, setup replication, backups, ACLs and enable the engineering department to evaluate the products. You run a replication environment with daily backups and failover capabilities which you test and verify regularly. Now there is a request for using MongoDB or Cassandra, the engineering department has not decided but they want to evaluate the capabilities. You are a MySQL shop.
So, after some analysis, and despite the fact that I really prefer Ansible over Puppet, I decided (so that it could still make sense in our infra) to go the “puppet modules way”. That was the beginning of a journey, where I saw a lot of Yaks to shave too.
