Variables namespaces in CodePipeline for multi-stage deployment pipelines

Thursday, 16 July 2020, 22:24

In November 2019 AWS CodePipeline introduced variables namespaces to allow passing outcomes of one pipeline action into another. Previously passing values between stages was very tricky and required involving of additional services (eg. S3 or DynamoDB). Things worked however little different if you were provisioning your pipeline with CloudFormation - since your pipeline definition was wrapped in a template you had a chance to inject deployment-time values into it via templating functions. To make things even more usable, but also complex, if you were defining CloudFormation step in CodePipeline you had an option to use Fn::GetParam function (which you couldn't use anywhere else, it was it's sole purpose). Now, with variables namespaces in CodePipeline and support for this feature in CloudFormation building more dynamic pipelines that manage your AWS resources in infrastructure-as-a-code approach and vice-versa became much simpler and robust!

Continuous Delivery with CodePipeline, CodeBuild and Maven

Saturday, 02 December 2017, 20:47

Neue Arbeit, neue Stadt, neue Blog Post. My adventure in HRS has finished. Time for the next step, but next step starts next Monday, so I have some time to spend with family and update my blog a little. As recently I was mainly involved into managing infrastructure of various projects on AWS and picked CloudFormation as a tool to manage all of the resources, I discovered a lot of quirks, sometimes undocumented behaviors, but mostly just built simple stuff from simple pieces that are working great with a minimum effort. Want to share some of my knowledge here, especially that AWS documentation is usually very fragmented, unclear or missing; which doesn't change the fact, that still - it provides all you need to build the stuff you want, managing most of them for you.
