How To: Install graylog2 on CentOS 5 with RVM + Passenger

I decided to see if RVM – Ruby Version Manager – would allow me to setup an isolated Ruby environment just for graylog2 and not disturb the other Ruby apps on the machine. I also wanted to setup an isolated instance of Passenger-standalone for graylog2 then configure apache to listen on port 80 and forwarding requests with mod_proxy.

Continuous Integration Tip #3 – Version your Databases as part of your automated build

Having a good Continuous Integration setup is the gift that keeps on giving, but what about your database? For most web applications these days, your database is a large part of your application – so why is versioning it such an uncommon thing?

Availability is a Feature… Like Anything Else

“Availability is the most important thing…” I heard this recently and I cannot agree with it. It sounds good, until you think about all the things that become less important things when you say something like that.

Automated Deployments with TeamCity, Deployment Projects & SVN

For some, the task of automated deployments seems either too difficult, too time consuming to setup or is perceived as un-needed. I’m about to attempt to prove all of these things wrong, while at the same time allowing you to get back to doing what you do best: write code.

Off-Loading Test Execution Using Hudson/Jenkins: Part 3, skipping the queue

Previously I had looked at preflighting, with Hudson (And Jenkins) but forgot to mention a very important plugin that is essential if you want to convince your developer to preflight there work. The problem is that is the slave allotment/smallholder/farm is busy running other jobs then they are forced to wait before merging.

Off-loading Your Test Execution Using Hudson/Jenkins: Part1

One thing we do is for every main hudson job we create a copy just to run the tests for a particular developer. It solves the "it runs on my machine" dilemma and frees up the developer to get on with other work.

Continuous Integration Tip #2 – Using App_offline.htm in Your Build

Deploying in an automated fashion using Continuous Integration doesn’t happen instantly, and depending on the size of your application, your continuous integration deployment can get caught in a state of unknown/in-between if a user visits your application half way through deployment.

Continuous Integration Tip #1 – FTP Deployment

Having a good Continuous Integration setup can be one of the highlights of any developers daily grind. Regardless, it can be seen as almost pointless if your automated deployment setup still needs a physical person to upload the files to your server if it is offsite. Adding FTP/SFTP to your CI process is the solution to this.

Evolving towards cookbook reusability in Chef

A few months ago, I started to invest heavily in Chef to automate the roll out of our applications and the supporting infrastructure. So far, so good but it has not always been sunshine and puppy dogs. One of the major challenges is attempting to reuse cookbooks found on the community site, on GitHub or even within our own organization.

Another Look at Continuous Delivery/Continuous Deployment

I’ve spoken to a lot of people about Continuous Delivery/Deployment over the years and a lot of the time i hear that the amount of time that it takes to implement it into a project is a cost their managers are simply not willing to allow them to incur. This is ludicrous.

The Build Monkey Antipattern

A common pattern in software development teams is to have a person who owns the build system. While it’s normal for some team members to have a deeper understanding of these things than others, it’s not a good idea for the knowledge and responsibility for the build to become overly concentrated in one person.
