The following snippet creates environment variables from your Grafana toml.
#!/bin/sh
# Script writes to env file and shows JSON lines on stdout
if [ -z "$2" ]; then
echo "USAGE: $0 ./inputfile.toml ./output.env"
fi
TF=/tmp/temp-grafana-conf.toml
echo "[default]" > $TF
cat $1|sed 's #.*$ ' >> $TF
> $2
while read l; do
if `echo $l|grep -q '^#'`; then
continue
fi
if `echo $l|grep -q '^\[.*\]$'`; then
PREFIX=`echo $l|tr -d '\[\]'`
continue
fi
if `echo $l|grep -q '='`; then
NAME="GF_$PREFIX"
NAME=$NAME"_`echo $l|awk '{print $1}'`"
NAME=`echo $NAME|tr a-z\.\- A-Z__`
VAL=`echo $l|sed 's/^.*\ =\ //'`
echo "export $NAME=$VAL" >> $2
echo "\"$NAME\": \"$VAL\","|sed 's "" " g'
continue
fi
done < $TF
The script isn’t perfect (arrays and mid line comments will fail) but it’ll save you some manual work.
