InfluxDB

InfluxDB is a time series database built from the ground up to handle high write and query loads. InfluxDB is meant to be used as a backing store for any use case involving large amounts of timestamped data, including DevOps monitoring, application metrics, IoT sensor data, and real-time analytics.

InfluxDB Documentation

Using this Image

Running the container

The InfluxDB image exposes a shared volume under /var/lib/influxdb, so you can mount a host directory to that point to access persisted container data. A typical invocation of the container might be:

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.

You can also have Docker control the volume mountpoint by using a named volume.

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

Exposed Ports

The following ports are important and will be automatically exposed when using docker run -P.

• 8083 Admin interface port
• 8086 HTTP API PORT

Other important ports that aren't exposed by default:

• 8091 Meta service port
• 8088 Clustering (raft) port

These two ports do not need to be exposed in a single server configuration.

Find more about API Endpoints & Ports here.

Configuration

InfluxDB can be either configured from a config file or using environment variables. To mount a configuration file and use it with the server, you can use this command:

Generate the default configuration file:

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

Modify the default configuration, which will now be available under $PWD. Then start the InfluxDB container.

$ docker run -p 8083:8083 -p 8086:8086 \
      -v $PWD:/etc/influxdb:ro \
      influxdb -config /etc/influxdb/influxdb.conf

Modify $PWD to the directory where you want to store the configuration file.

For environment variables, the format is INFLUXDB_$SECTION_$NAME. All dashes (-) are replaced with underscores (_). If the variable isn't in a section, then omit that part.

Examples:

INFLUXDB_REPORTING_DISABLED=true
INFLUXDB_META_DIR=/path/to/metadir
INFLUXDB_DATA_QUERY_LOG_ENABLED=false

Graphite

InfluxDB supports the Graphite line protocol, but the service and ports are not exposed by default. To run InfluxDB with Graphite support enabled, you can either use a configuration file or set the appropriate environment variables.

HTTP API

Creating a DB named mydb:

$ curl -G http://localhost:8086/query --data-urlencode "q=CREATE DATABASE mydb"

Inserting into the DB:

$ curl -i -XPOST 'http://localhost:8086/write?db=mydb' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'

Read more about this in the official documentation

CLI / SHELL

Start the container:

$ docker run --name=influxdb -d -p 8083:8083 -p 8086:8086 influxdb

Run the influx client in another container:

$ docker run --rm --link=influxdb -it influxdb influx -host influxdb

Alternatively, jump directly into the container:

$ docker exec -it influxdb influx

Web Administrator Interface

Navigate to localhost:8083 with your browser while running the container.
