Jenkins Spark integration

You can make Jenkins publish messages to spark after or during builds. Here’s how we do this: 1. Get the spark room ID that you want to use:

curl https://api.ciscospark.com/v1/rooms -X GET -H "Authorization:Bearer SUPERLONGAUGZjg5ZjRhZDAtMDA1NC00OMzRmMjg5NTJiMTUwOTZkZDgtYTY0" | python -m json.tool

1	curl https://api.ciscospark.com/v1/rooms -X GET -H "Authorization:Bearer SUPERLONGAUGZjg5ZjRhZDAtMDA1NC00OMzRmMjg5NTJiMTUwOTZkZDgtYTY0" \| python -m json.tool

This will give you a list of rooms. From here, you can find the room you want and get the ID of the room: Something like: Y2lzY29zcGFtxuovL3VzL1JPT00vOWRhMjY1MDAtOWY2Zi0xMWU1LTg0ODQtNzczOTMxZTUxMGE3 […]

Go with NX-API

I’ve been working on a project to collect data from Cisco Nexus switches. I first tackled making SNMP calls to collect counter statistics but then I thought, why not try it with the NX-API that came with the Nexus 9ks? The documentation for the APIs I hoped would be better, but the samples on github […]

Continuous Delivery of a Simple Web Application Tutorial – Part 4

In Part 1 we discussed the architecture of what we’re trying to build. In Part 2 we created our development server with Ansible. In Part 3 we finished off Ansible with creating our Load Balancers and WebServers and setup Git to check everything in. In this last part, we’re going to configure Jenkins to use all of these components […]

Continuous Delivery of a Simple Web Application Tutorial – Part 2

In Part 1 we gave the general outline of what we are trying to do, the tools we’re using, and the architecture of the application. In this part (Part 2) we’re going to work on building the development environment with Ansible. This includes the Jenkins, Gitlab, a private Docker Registry, and a proxy server so we […]

Continuous Delivery of a Simple Web Application Tutorial – Part 1

This will be the first of a series of posts showing how we can do continuous delivery of a simple web application. This will be written tutorial style to show all the different components used. We are using Open Source tools on Cisco OpenStack private cloud, but the majority of the instructions here could be […]

Debug CoreOS Cloud Init Script

When I log in after trying to debug something I find that the command prompt gives me the following:

core@ci ~ $ ssh -i tco-gold.pem core@10.2.3.6
Last login: Wed May 27 19:45:10 2015 from 10.2.3.7
CoreOS stable (633.1.0)
Failed Units: 1
  coreos-cloudinit-547659032.service

core@ci ~ $ ssh -i tco-gold.pem core@10.2.3.6

Last login: Wed May 27 19:45:10 2015 from 10.2.3.7

CoreOS stable (633.1.0)

Failed Units: 1

coreos-cloudinit-547659032.service

So to figure out where my script went wrong, I simply have to run the command:

systemctl status -l <name of service>

1	systemctl status -l <name of service>

So in my case it was:

core@coreos633-jenkins-slave ~ $ systemctl status -l coreos-cloudinit-547659032.service

Can AWS put out the private cloud?

TL;DR: No. Today I watched a recording of Andy Jassy at the AWS summit in San Francisco from last month. (Yes, I have a backlog of Youtube videos I’m trying to get through and John Oliver takes precedence to AWS) The statistics he laid out were incredible: 102% YoY revenue growth for the S3 service […]

Deploying Instances on COPC (metacloud) with Ansible

I wanted to show a quick example of how to deploy an instance on Cisco OpenStack Private Cloud (COPC or Cisco OPC or MetaCloud) with Ansible. Since COPC is just a fully engineered and operated distribution of OpenStack from Cisco, this blog is also applicable to normal OpenStack environments. I’m a big fan of Ansible […]

VMware is the AOL of the private cloud

This week at VMware Partner Exchange there was a nice announcement of VMware Integrated OpenStack or VIO. VIO attempts to do what most of the developers of OpenStack have failed to do: Make OpenStack easy to deploy and manage. (It’s not, anybody who tells you different is trying to sell you something). The sound bite […]
