It is a reality that we tend to make things harder than they might be when we try to use and connect various databases. Since docker came out things became a lot easier.
Most databases like Mongodb, InfluxDB etc come with the binaries needed to spin up the database but also with the clients needed in order to connect. Actually it pretty much starts to become a standard.
We will make a showcase of this by using InfluxDB’s docker image and the data walkthrough.
Let’s start with spinning up the instance.
docker run --rm -p 8086:8086 --name influxdb-local influxdb
We have an influxDB instance running on port 8086 under the name influxdb-local. Once the container is stopped it will also be deleted.
First step is to connect to an influxDB shell and interact with the database.
docker exec -it influxdb-local influx CREATE DATABASE NOAA_water_database > exit
Now let’s import some data
docker exec -it influxdb-local /bin/bash curl https://s3.amazonaws.com/noaa.water-database/NOAA_data.txt -o NOAA_data.txt influx -import -path=NOAA_data.txt -precision=s -database=NOAA_water_database rm NOAA_data.txt
Next step is to connect to the shell and query some data.
docker exec -it influxdb-local influx -precision rfc3339 -database NOAA_water_database Connected to http://localhost:8086 version 1.4.x InfluxDB shell 1.4.x > SHOW measurements name: measurements name ---- average_temperature h2o_feet h2o_pH h2o_quality h2o_temperature >
As you can see we just created an InfluxDB instance with data ready to execute queries and have some tests! Pretty simple and clean. Once we are done by stopping the container all data and the container included shall be removed.
