Easily provision Windows instances in AWS with Ansible

MYTH: using Ansible to do fully-automated provisioning of Windows instances in AWS is difficult, because WinRM is not enabled by default on Amazon’s Windows AMIs, and the admin password is not known at startup.

I’d like to bust this myth once and for all. As an Ansible Solutions Architect, I often see users going to great lengths to solve both of these problems. The solutions I’ve encountered in the field have ranged from “minor maintenance hassle” to “major code-smell”, and are usually completely unnecessary; an obscure EC2 feature called User Data can replace them all. In a post on my personal blog, I demonstrate a basic use of this feature to manually provision Windows instances that are Ansible-ready on first boot, using unmodified Amazon-provided AMIs. A follow-up post expands that technique into a fully-automated provisioning sample. Try it yourself to see how easy it is to quickly spin up and configure Windows instances for any need, using only Ansible!

Checking Out GitHub Pull Requests Locally

In this post, I’m going to show you how to use the Git command-line to check out GitHub pull requests locally. I take absolutely no credit for this trick! I picked this up from this GitHub Gist, and merely wanted to share it here so that others would benefit.

The GitHub gist shows you how to modify the Git configuration for a particular repository so that when you run git fetch it will fetch all the pull requests for that repository as well. This is handy, but what I personally found most helpful was a comment that showed the command to fetch a specific pull request. The command looks like this:

git fetch origin pull/1234/head:pr-1234

Let me break that command down a bit:

• The origin in this case refers to the Git remote for this repository on GitHub. If you are using the fork-and-pull method of collaborating via Git and GitHub, then you will have multiple Git remotes—and the remote you want probably isn’t origin. For example, if you want to fetch a pull request from the original (not forked) repository, you’d want to use the name that corresponds to the Git remote for the original repository (I Continue reading

VMworld 2015 Day 2 Keynote Liveblog

The day 2 keynote kicks off with another Cloud Academy presentation… After the video wraps up, Sanjay Poonen takes the stage. Poonen briefly recaps yesterday’s messaging, and then moves into the focus of today’s keynote—focusing on the “any application and any device” part of the “Ready for Any” messaging.

According to Poonen, the core of the solution for “any application on any device” is VMware’s Workspace Suite. Workspace Suite creates the magic of “enterprise computing with consumer simplicity.” How? It starts by building upon the core of virtualized infrastructure, made possibe by VMware’s compute, storage, and network virtualization solutions. Combined with a strong management layer and hybrid cloud solutions, this becomes the software-defined data center (SDDC). Somehow, though, this stuff needs to be connected to the end users—via desktop, mobile, content collaboration, and tying it all together with identity management. Poonen points to innovation in all of these areas.

Obviously, mobile is a category that is growing very rapidly, and Poonen talks about VMware’s movement in this space via the AirWatch acquisition. And the use of mobile devices is also key to VMware’s identity efforts as well. Poonen shows a video with a few customer testimonials, and then introduces Continue reading

This is a liveblog for the Day 1 general session at VMworld 2015 in San Francisco. For many people, VMworld started yesterday with the Welcome Receptio in the Solutions Exchange, but today marks the official kick-off to the event. I’ll have to end this liveblog shortly before the general session ends in order to make it to some customer meetings.

The keynote kicks off with a short video about the VMware Cloud Academy, where both “legacy” and “cloud-native” apps can enjoy the Unified Hybrid Cloud. Following that video, Carl Eschenbach takes the stage (along with some “apps”). Eschenbach sets the stage for the session by talking about the momentum and volume of success that VMware has enjoyed (and continues to enjoy). He also calls out VMware’s philanthropic efforts, via the VMware Foundation and the #vGiveBack program.

Eschenbach nexts dives a bit deeper on the theme of the show, “Ready for Any.” This means VMware technologies and products supporting any application, any cloud, any infrastructure, any time, any place…you get the idea. This theme encompasses SDDC (software-defined data center) initiatives, mobility initiatives, and EUC (end-user computing) initiatives. Eschenbach talks in a a bit more detail about how Unified Hybrid Cloud Continue reading

Make Your Life Easier by Creating Utilities and Delegating Playbooks

Last week we hosted our second session of the Tips & Tricks webinar series and focused on creating utilities and delegating playbooks. We want to make your life easier by helping you to automate tasks and then delegate the execution. Ansible is not a programming language, but you can use it as one. Here’s what you need to know…

#1 Create executables that someone else can use

Leverage the shebang (#!) and use ansible as you would any scripting language to create utilities that can reuse your existing playbooks, roles and task lists.

#2 Use permissions to segment access

Unix permissions (and ACLs) can be used to restrict access to inventory and to the users/keys needed to access the defined hosts. You can also restrict which utilities can be executed (sudo).

#3 Use Ansible to make ad-hoc systems

Ansible is a Unix tool, as such it can be combined with others (cron, incron, netcat, ucspi, etc) to create automated workflows.

Watch the entire webinar now.

If you missed Brian's first Tips & Tricks session on Live Systems, you can watch it here. 

Next up is Tips & Tricks: QA on September 17, at 3PM Eastern. Register now and Continue reading

Uncontaina-bull: The love for Ansible + Docker

Here at Ansible, we normally leave it up to our good friend @Ansibull to deploy the puns. But having just joined Ansible in the past few weeks, I’ve been spending some time getting acquainted with the vast quantity of Ansible resources produced by the lovely folks in the community, and I have to say, the amount of great content out there is just…

In-cow-cula-bull.

This is especially great for those of us looking how to do Ansible + $justaboutanything: Ansible + OpenStack, Ansible + Drupal, Ansible + CoreOS, or, as you may have guessed, Ansible + Docker.

Of course, Ansible has some useful resources for how to use Docker with Ansible. But the beautiful thing about what all of our friends in the community are writing is that they’re sharing all the things they learned along the way, how it helped out their company or workplace, what puzzles they had to solve; basically, things you may run into yourself, or ideas that may be inspiring to you that you hadn’t thought of just yet.

And to not share those things with everyone else? That would be, ahem, unthinka-bull. So without further ado: Here’s just a little bit of the latest Continue reading

Technology Short Take #53

Welcome to Technology Short Take #53. In this post, I’ve gathered links to posts about networking, virtualization, Docker, containers, Linux, configuration management, and all kinds of other cool stuff. Here’s hoping you find something useful!

Networking

• Anthony Spiteri, who works at an Australian service provider running NSX, has some in-depth articles discussing vShield Edge and NSX Edge (part 1, part 2, part 3, and part 4). Anthony discusses features supported by both, how they handle high availability, how VPN services work, and how to handle certificates. It looks like very useful information for anyone supporting NSX in their environment.
• Here’s a nice article on using Ansible with Arista EOS. This isn’t something I’ve had the chance to do just yet (currently needing to focus my efforts on Ansible with Linux/Cumulus Linux), but it certainly seems relatively straightforward. Without having done this myself, it seems like I’d prefer to run pyeapi on the switches directly, so the Ansible configuration remains clean (instead of having to use a local connection for the switches but SSH for everything else). Of course, I’m sure there are trade-offs each way.
• I think I’ve mentioned this before (it’s really hard to Continue reading
