This Dockerfile is generated, that is why it looks so ugly. The main reason was that I did not want to have any external dependencies. Instead of using ADD I decided to go for writing files using this technique
echo <base64decoded> | base64 -d > /tmp/<md5> && mv /tmp/<md5> <dst>
and just inline everything in the Dockerfile.
OpenTSDB is started with the --auto-metric flag so you do not need to create metrics before you write to them.
By removing the comment in line:
# RUN cd /opt/opentsdb && git checkout origin/next
you can already test OpenTSDB 2.0
You need to download the Dockerfile and build a new image:
docker build -t opentsdb .
id=$(docker run -d opentsdb)
port=$(docker port $id 4242)
echo "started opentsdb in container $id, listening on $port"
Now you can wait for OpenTSDB to be fully started (this can take a while)
for i in $(seq 1 30); do
curl -sfI 127.0.0.1:$port > /dev/null 2>&1
if [ "$?" == "0" ]; then
echo "opentsdb running and listening on port $port"
break
fi
echo -n "."
sleep 1
done
The OpenTSDB frontend is now available on the displayed port.
With OpenTSDB running you can start to feed your first metrics:
while true; do
line="put load.loadavg1m $(date +%s) $(cat /proc/loadavg | cut -d ' ' -f 1) host=$(hostname)"
echo $line
echo $line | nc 127.0.0.1 $port
sleep 1
done
and with that loop running you can have a look at your metrics:
