## Set additional docker run arguments by changing the variable
## i2p_www_docker_run_args in an optional file called config.sh
## for example
##
##i2p_www_docker_run_args='-d'
## to run the site in the background, or
##
##i2p_www_docker_run_args='-t'
## to emulate a TTY

## To operate a quick and easy mirror of the I2P Site in a container
## simply clone the i2p.www source to a host with Docker installed, then 
## add:
##
##i2p_www_docker_run_args='-d'
## to config.sh
##
## Then add:
##
##*/10 * * * *	/path/to/i2p.www/site-updater-docker.sh
##
## to a crontab belonging to a member of the `docker` group. To add yourself
## to the `docker` group use the command:
##
##sudo adduser $(whoami) docker
##
## a more secure solution may be to create a user especially to run the
## docker crontab only, who is a member of the docker group. To do this,
##
##sudo adduser --disabled-password --disabled-login --ingroup docker docker
## however the specifics may vary from distribution to distribution.
