#/bin/bash

#this script is run when the container is started
#optionally adds $CONTAINERKEY to shiny server url by modifying shiny-server.conf
#
#example:
#http://<IP>:<PORT>
#->
#http://<IP>:<PORT>/<CONTAINERKEY>
#
#to use this add the "-e" parameter when starting a container:
#docker run ... -e CONTAINERKEY=${container_key} ...
#example:
#docker run --name='sav1' -d -p 50000:3838 -v '/mnt/agnerds/docker/projects/sav1':'/srv/shiny-server/data' -e CONTAINERKEY=sav1 loosolab/wilson:1.2"
#-> http://<IP>:50000/sav1
