Jenkins Spark integration

Posted on April 27, 2016 by Vallard

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…

Jenkins running in Docker image behind firewall

Posted on February 2, 2016 by Vallard

When you run jenkins behind a firewall you need it to get out. You’ll have to set up proxies to let this happen. Here’s how I make it run: First, make coreos able to go out of your network:

sudo mkdir -p /etc/systemd/system/docker.service.d
cd /etc/systemd/system/docker.service.d/
touch http-proxy.conf

sudo mkdir -p /etc/systemd/system/docker.service.d

cd /etc/systemd/system/docker.service.d/

touch http-proxy.conf

Next edit http-proxy.conf and make it look like:

[Service]
Environment="HTTPS_PROXY=http://proxy.esl.cisco.com:80"

1 2	[Service] Environment="HTTPS_PROXY=http://proxy.esl.cisco.com:80"

This will allow docker to get outside…

Continuous Delivery of a Simple Web Application Tutorial – Part 4

Posted on June 15, 2015 by Vallard

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 1

Posted on June 4, 2015June 15, 2015 by Vallard

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

Posted on May 27, 2015 by Vallard

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

Cisco OpenStack Private Cloud Developer Demo

Posted on April 14, 2015April 14, 2015 by Vallard

In my new role here at Cisco I show people how powerful the Cisco OpenStack Private Cloud solution can be for developers. I made the below video last night to demonstrate continuous integration. The video is a scenario for a new company called lawngnomed.com. The company provides lawn gnomes as a service (LGaaS). Under the…
