post-mortemPost Mortem zum KreditSmart Incident vom 20.02.2018Am Dienstag, dem 20. Februar 2018 kam es in der Zeit von 13 bis 17 Uhr zu einem mehrstündigen Ausfall von KreditSmart und dem Vorgangsmanagement. Wir möchten hier kurz schildern, wie es dazu kam und wie wir eine Lösung erarbeitet haben.

build-toolsRunning Multiple Local Tomcats with Cargo and GradleWe are currently using Cargo in combination with Gradle to implement consumer based tests for one of our projects. In order to do so, we created a Gradle script to deploy a service web app into a Tomcat container via Cargo and pass its URL to our consumer test suite. As long as we run the build script locally, everything works fine. But we noticed that it failed every once in a while when running on certain build agents in our TeamCity build pipeline.
