To escape any weird characters that could break your script, and according to reasoning from Mark's answer, add this line to your entrypoint.sh:

env | sed -r "s/'/\\\'/gm" | sed -r "s/^([^=]+=)(.*)\$/\1'\2'/gm" \ > /etc/environment

This way, if you have any variable like affinity:container==My container's friend, it will be converted to affinity:container='=My container\'s friend, and so on.
