I'm running Shiny Server inside a docker container on a Kubernetes cluster. The cluster uses a suite of logging and monitoring tools (including Sumo Logic and New Relic). However, I can't really utilize these tools because the logs that I care the most about, the application error logs, are written to a log file and not standard out, as the Server log is. Even ad hoc monitoring using docker log or kubectl log is impossible. Is it possible to route the application logs to standard out?
