How to install Fluentd plugins on k8s

Question

I have set up EFK on Kubernetes, currently I have access only to logs from logstash but wondering how can I install some plugins for Fluentd in order to get some logs from eg. NGINX which I use as a reverse proxy? Can someone please point me how exactly I can configure EFK on k8s and what are the best practices around it? On k8s I have eg. API service in Express JS.

Also there are a lot of fluentd plugins for kubernetes here: https://www.fluentd.org/plugins/all#stq=kubernetes&stp=1

Each plugin has installation instruction, for example Kubernetes Logging with Fluentd
