# Pull in any arguments and set defaults

## Where should we store your user data
# DATA_DIR=/opt/xibo
DATA_DIR=$(pwd)

## What version do you want to run
CMS_VERSION=latest
XMR_VERSION=latest

## SMTP Server Configuration
## The CMS needs to be able to send email to you
## Please enter credentials for a suitable SMTP server
## Defaults will work for GMail - replacing your GMail username
## and password as appropriate. You will also need to enable access
## for less secure applications on your GMail account for this to
## work. See https://support.google.com/accounts/answer/6010255

## SMTP Server Hostname
XIBO_SMTP_SERVER=smtp.gmail.com:587
## SMTP Username
XIBO_SMTP_USERNAME=youraccount@gmail.com
## SMTP Password
XIBO_SMTP_PASSWORD=yourpassword
## Use a TLS Connection YES/NO
XIBO_SMTP_USE_TLS=YES
## Use a STARTTLS Connection YES/NO
XIBO_SMTP_USE_STARTTLS=YES
## Rewrite domain (the domain your email will appear to come from)
XIBO_SMTP_REWRITE_DOMAIN=gmail.com
## Hostname that we should identify ourself to the remote server as
XIBO_SMTP_HOSTNAME=$XIBO_SMTP_REWRITE_DOMAIN
## Can the From line be overridden in the outbound email
## NB GMail will rewrite the From address anyway so it's not important
## for GMail - YES/NO
XIBO_SMTP_FROM_LINE_OVERRIDE=YES

## What root password would you like to use for
## your MySQL server
## To generate a random password, use this default
MYSQL_ROOT_PASSWORD=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 16)
## Alternatively uncomment the following line to set your preferred choice
#MYSQL_ROOT_PASSWORD="root"

## Which port should XMR listen on for Players?
XMR_PLAYER_PORT=9505

## Which port should the Xibo CMS Webserver listen on?
WEBSERVER_PORT=8080

# Name prefix for the containers used in this
# application
