 * * xs: < 576 -  Extra small devices (portrait phones, less than 576px)
 * * s:  >= 576 -  Small devices (landscape phones, 576px and up)
 * * m: >= 768 -  Medium devices (tablets, 768px and up)
 * * l:  >= 992 -  Large devices (desktops, 992px and up)
 * * xl: >= 1200 - Large desktops, 1200px and up

# Two possibilities to parse a Postgres DB URL from heroku into environment variables
# that Spring Boot understands.
# You would need that, if you do not build on heroku but push docker images
# from another source
# Does not need bash. Works on alpine linux / busybox. Tested with openjdk:8-jdk-alpine base image.

export DATABASE_URL=postgres://user:password@host:port/database

# Naive way, would break with [@:/] in username or password.
DB_TYPE=$(echo $DATABASE_URL | awk -F'[:@/]' '{print $1}')"ql"
