To help developers leverage the standalone application router without having the overhead to build or maintain docker images, SAP recently made the application router docker image publicly available.
The tag corresponds to the SAP Application Router npm version
What does this mean for cloud-native developers using SAP BTP Kyma runtime?
You are building applications that need to integrate with BTP and want to leverage the application router's authentication/authorization and logging capabilities. You no longer need to build and maintain the docker image by yourself. You can directly use it in your Kubernetes deployments.
