What is frp?
frp is a fast reverse proxy to help you expose a local server behind a NAT or firewall to the internet. Now, it supports tcp, http and https protocol when requests can be forwarded by domains to backward web services.

This images includes only the server binary "frps" and it is based on Alpine Linux for a small footprint (~8MB).
A data volume must be mounted which will include the frps configuration and possibly the log file.
Logging is printed to stdout by default so you can see it through the docker logs command. If you want to log to a file you can set this from the configuration file.
Everything depends on your configuration. For example if you use the default ports for frp, you could run the image like this:
docker run -d --name frps -v $frp-data:/data -p 7000:7000 -p 7500:7500 -p 2000-3000:2000-3000 thanosme/frps
Ports 2000-3000 are an example for priveleged ports. Basically you can open the ports you want based on your configuration.
