Jetbrains’ build server software
TeamCity is an awesome product to get up and running with continuous integration and deployment, however with its ease of operation it leaves a few nice to have business features aside. One of these is Scheduled backup – and if there is anything that your career has probably taught you to date, it’s that when things break, having a backup is priceless.
Web.config transformations have been around for a while now, and a lot of developers use them in their staple day-to-day environment deployment strategies – hell, Scott Hanselman was spouting about them way back in the beginning on 2010 with his “
Web Deployment Made Awesome: If you’re using XCOPY, you’re doing it wrong” post. As usual though, one size does not fit all – and in the case of Continuous Integration fans out there that may have specific build-configuration-based build and deployment scenarios (such as myself), there is the need to have finer grained control over the Web.config transformation process. If this sounds like you, then this post is aimed to deliver.
TeamCity is one of the greatest tools to hit the Continuous Integration world, with free licensing for 20 build configurations and an easy to use interface it ticks all the right boxes (not to mention ease of use for Windows Users) – but once you splash out on an Enterprise license and grow your installation to house many build configurations you start to want more power, and this is when a second build agent is your ticket to freedom.
When updating a project’s Database Schema as part of your deployment strategy, you want to automate as much of the process as possible to avoid human errors. If you have a Visual Studio Premium installed on your build server, generating schema update scripts is easy to achieve with the built-in database tools that the IDE contains. I will show you how to do this easily and also automatically deploy the changes to your destination server with the awesomeness of TeamCity.
I have recently had a couple of interesting discussions with a different people on twitter and “the real world” about the use of third party build dependencies such as unit testing frameworks, database versioning tools and other command line executables in your build. The topic of these discussions has been about where these dependencies should be located, inside your project, or installed on your build server.
Last week i had the awesome honour of being at a tech talk on

Thoughtworks here in Sydney. I have spent the last two years of my life evangelizing on the benefits of Continuous Integration and Continuous Deployment to anyone who would hear me all on my own terms and entirely self taught in the dark. I have selected snippets and ideas from other peoples documented ways on how they achieve Continuous Deployment, but the experience of listening to pioneers in this space was a truly awesome experience.
Test Driven Development, Behaviour Driven Development, Extreme Programming and many other new-age hippy development methodologies have spread through the development world like wild fire. I believe there is room for one more in the shape of Build Driven Deployment/Automated Deployment - A new source of confidence in the development world. Time to go out and spread the word.
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? Because it’s time consuming and complicated – two requirements that Continuous Integration love conquering with a one-two punch.
If on your first ever start of Visual Studio you pick a layout that happens to be missing the oober aweshuum “Build configuration” dropdown menu from your toolbar and are struggling to find it in the Build toolbar (i know i was..) here is how you add it back:
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. This can be far from optimal, but ASP.Net has a trick up it’s sleave in the form of the App_offline.htm file.
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.
One of the continually high risk and sometimes fiddly operations in web deployment is a web application’s deployment, and yet a lot of people working in smaller teams seem to have become stuck in the land of cowboys because 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.
