The semantic versioning used in all of our TFS/VSTS CI builds uses the predefined variable Build.BuildID for the buildnumber portion of major.minor.revision.buildnumber. The build id is used so we have traceability when troubleshooting. We can easily search for the build and see the associated changes. Major.minor.revision is set in a variable group so it can be shared and updated in one place, across build definitions.

I recently set out to automate the creation of our Windows build servers that run VSTS agents. Previously the build servers were thought of as “snowflake” servers because of all the software components and customization’s that were needed. This was even more reason to use Infrastructure as Code to get rid of manual run books that were previously used to document the creation of a build server. Our Infrastructure team already decided on a tool chain for Infrastructure as Code, which included Chef for Configuration Management.

In order to gracefully deploy releases to our application servers, I wanted to utilize rolling deployments in Octopus Deploy. If you aren’t familiar, rolling deployments slowly roll out a release one instance at a time (vs. all instances at once). The goal of this being reduced overall downtime. To accomplish this, I wrote PowerShell scripts to leverage AWS Auto Scaling Groups (ASG) that are run as part of Octopus deployments.

This past week I started concentrating on optimizing our release processes. I’ve talked about how our team uses VSTS and Git in a previous post. At the end of a sprint, pull requests are created in all of our repositories to merge to the release branches. As the number of our repositories continues to grow, the number of manual steps to merge for releases grows exponentially. Having worked with the VSTS REST API in the past I knew this wouldn’t be difficult to automate. A build would be run that runs the script below for each of our repositories to create pull requests. Service hooks to Slack would then send notifications so the necessary reviewers can approve the newly created pull requests. This same script can be used post release to merge back to Master branches. I commented on every line of code in the script below so I didn’t have to go into details here 🙂
