I would like to use rsyslogd (ultimately with omkafka) inside a Docker container (in a Kubernetes sidecar container, actually). Docker Hub says rsyslog/syslog_appliance_alpine was "updated 3 years ago", the image identifies itself with "rsyslog appliance version 2018-06-26", and it runs rsyslogd 8.36.0 (which is also from 2018).
Are these relatively old dates a feature or a bug, and what is my best option for running rsyslogd inside a container these days?
