Join the DZone community and get the full member experience.
Join For FreeSince we added our base application it is time for us to spin up an InfluxDB instance.
We shall follow a previous tutorial and add a docker instance.
docker run –rm -p 8086:8086 –name influxdb-local influxdb
Time to add the micrometer InfluxDB dependency on our pom

It's also time to add the configuration through the application.yaml

Let’s spin up our application and do some requests.

curl localhost:8080/jobs/github/1
After some time we can check the database and the data contained.

docker exec -it influxdb-local influx
