It’s been a long time right? I mean ~really~ long time since I’ve posted anything. I apologize. It’s been a crazy summer. And Fall. You don’t want the details – trust me, it has very little to do with KVM or storage. I think I’m back to being able to devote some time to helping you kind and patient people out with technology again, so hopefully you haven’t completely abandoned me. 🙂
Today, I’d like to introduce the concept of Heat templates. Essentially, where we left off before was that we’ve got OpenStack up and running, we’ve got some cloud images built, but we’re really not automating anything. This is where Heat comes in.. Continue reading “Intro to Heat Templates”
In today’s post we’re going to revisit our old standby tool, “PackStack”. Why? Because it’s worth remembering that it’s a solid tool to work with, even if it’s not very flexible. As much time as I spent on the RHEL-OSP Installer, what if you just want to stand up 2 or 3 nodes and be done with it? The Installer might be overkill. But then again, what if you want to duplicate what I did regarding the network prep in the Installer with PackStack?
Boom! That’s ~exactly~ what we’re doing today. Continue reading “PackStack for RHEL-OSP Revisited”
In the last 2 posts we covered creating a custom cloud image for RHEL, then editing it with “guest fish”. Today, I’ll introduce you to another tool called “oz” as we continue our journey into creating custom cloud images. The way we did things last time using “virt-manager” is fine if you’re doing an image here or there.. but let’s face it, walking through anaconda is cumbersome. Granted, I showed you how to do things using the CLI and kickstart, but I think you’ll like this way even better. Continue reading “Custom Cloud Images for OpenStack pt3”
In the last post, I essentially kicked off a new multipart series on creating custom cloud images for RHEL, Fedora, and CentOS. I showed you the basics for RHEL, then said I would follow up with Fedora or CentOS. I lied. I decided that I wanted to show you a little fun with “GuestFish” (guestfs, libguestfs) first. It’ll be a quick post with some links to take you further should you want to take things deeper… Continue reading “Custom Cloud Images for OpenStack pt2”
We previously finished our multi-part series on deploying RHEL-OSP with the RHEL-OSP-Installer. In a few weeks, if all goes according to plan I’ll fire up a new series on the next gen installer… In the mean time, I’d like to show you some useful things to do once you’ve got everything up and running. So what’s up first? Well, as the title suggests, we’re going to create some custom images.
Specifically for RHEL, Fedora, and CentOS. Our new and current multi-part series… Continue reading “Custom Cloud Images for OpenStack pt1”
We’re finally here. The Big Enchilada. The Full Monty. The Full HA. It’s actually not as scary as it seems. But it should be… what I mean is that we should take the time machine back a year so that you could do all of the HA stuff manually. That way you could feel the pain of your own typos as you set up 100 different services under cluster services.. The trepidation of starting things up after 3 weeks of following directions to the “T”, wondering “is this going to work” or “am I going to drop to the floor in fetal position as my co-workers mock me”?
That way, you could see what a luxury 90 minutes for a 4 node cluster is.. 🙂 Continue reading “OpenStack Installer pt8 – Full HA”
In the last post, I mentioned that with any luck the next post would include a full HA deployment. Little did I know how (almost) true that would be. On Feb 9, RHEL-OSP 6 “dropped” (was released) and was “officially released” (full fanfare) on Feb 17. Last week’s release also included a full update to the RHEL-OSP Installer.
Lots of changes. 🙂 Continue reading “OpenStack Installer (for RHEL-OSP) pt7 – (Updates for RHEL-OSP 6)”
If all went well with your deployment of the RHEL-OSP Installer, then you likely didn’t wait for me to do a post on how to put up a cursory instance or two. If you fall into that category, good for you. If you’re really new to this stuff and were patient, that’s okay too. We’re going to not only stand up an instance, but all of the little things that you need to do as well.
Let’s get going. Continue reading “OpenStack Installer (for RHEL-OSP) pt6”
So in the last post, I finally gave up the goods and showed you how to use the RHEL-OSP Installer to blow out a 3-node non-HA OpenStack deployment. Hopefully, it worked for you without any issue whatsoever. What would be even better, is if you ran into at least 1 or 2 problems..
Yes, you heard me (read me) right. I hope you ran into 1 or 2 problems. Read on, and I’ll tell you why.. Continue reading “OpenStack Installer (for RHEL-OSP) pt5 – troubleshooting”
It only took us 4 posts to get to the brass tacks. I suppose I could have gotten here sooner, but I wanted to be sure I covered the bases properly along the way. The background, the lab, the host OS, and the installation of the application itself – otherwise the blog post would have been HUGE. (This still ended up being a larger post.) I’ve got one more huge suggestion before we start deploying nodes.
Label everything. Continue reading “OpenStack Installer (for RHEL-OSP) pt4”
