if [ ! "$SECRET_KEY" ]; then
SECRET_KEY=`cat /dev/urandom | tr -dc A-Za-z0-9 | head -c 50`;
echo "SECRET_KEY=$SECRET_KEY" >> ~/.bashrc;
echo $SECRET_KEY;
else
echo $SECRET_KEY;
fi
if [ ! "$BOOTSTRAP_TOKEN" ]; then
BOOTSTRAP_TOKEN=`cat /dev/urandom | tr -dc A-Za-z0-9 | head -c 16`;
echo "BOOTSTRAP_TOKEN=$BOOTSTRAP_TOKEN" >> ~/.bashrc;
echo $BOOTSTRAP_TOKEN;
else
echo $BOOTSTRAP_TOKEN;
fi
