What is Cort-Updater?

​

​

​

• It’s a service that pushes event and venue information to Publish API

​

• Fully-contained in Docker container

​

• Deployed in AWS

​

Good and bad: Docker

​

​

​

• Relatively high learning curve – especially in the beginning

​

• Different versions of OS on developer machines must be taken into account

​

• Docker and Vagrant cannot work together in the same time on Windows

GitLab Pipeline and build process

Good and bad: AWS and Terraform

​

​

​

• Terraform must be used in order to create machine specs. However, developers do not have permissions to run Terraform configurations in production – this lead to problems on release day

​

• Too many changes and lack of consistent approach regarding AWS in general. This is mainly due to lack of standards at the time – situation is different now

​

• Moving to AWS did not present any problem for QA, because there were no significant changes in the way they do their job. Flexibility of QA framework also helped the transition

Other problems

​

​

​

• Many changes regarding the product itself and the way it should work

​

• Many changes regarding the integration with Publish API

​

• Unclear technical details
