How to change influxdb storage location

3/15/2017

I have installed influxdb in docker container (Kubernetes) and I have mounted a persistent volume to that container. But influxdb is not writing data to that volume. Can anyone please tell me steps, so that influxdb will write data in particular volume. Thanks

Short Answer:

   $ docker run -p 8083:8083 -p 8086:8086 \
          -v $PWD:/var/lib/influxdb \
          influxdb

Modify $PWD with the path to external volume.

Long answer:

docker run -p 8083:8083 -p 8086:8086 influxdb

By default this will store the data in /var/lib/influxdb. All InfluxDB data lives in there. To make that a persistent volume (recommended):

$ docker run -p 8083:8083 -p 8086:8086 \
      -v $PWD:/var/lib/influxdb \
      influxdb

Modify $PWD to the directory where you want to store data associated with the InfluxDB container.

For example,

 $ docker run -p 8083:8083 -p 8086:8086 \
              -v /your/home:/var/lib/influxdb \
              influxdb

This will store the influx data in /your/home on the host.

If you pulled official influxdb image from docker library, the default path for data files is:

/var/lib/influxdb

To verify, Run an standalone instance:

docker run -p 8083:8083 -p 8086:8086 \
      -v $PWD:/var/lib/influxdb \
      influxdb

To check out the default config:

docker run --rm influxdb influxd config > influxdb.conf

Then use vim influxdb.conf

To run influxdb with custom config:

docker run -p 8086:8086 \
      -v $PWD/influxdb.conf:/etc/influxdb/influxdb.conf:ro \
      influxdb -config /etc/influxdb/influxdb.conf
