What is InfluxDB?

%%LOGO%%

InfluxDB is the time series database platform designed to collect, store, and process large amounts of event and time series data. Ideal for monitoring (sensors, servers, applications, networks), financial analytics, and behavioral tracking.

Start InfluxDB 3 Core

%%COMPOSE%%

Alternatively, you can use the following command to start InfluxDB 3 Core:

docker run --rm -p 8181:8181 \
  -v $PWD/data:/var/lib/influxdb3/data \
  -v $PWD/plugins:/var/lib/influxdb3/plugins \
  %%IMAGE%%:3-core influxdb3 serve \
    --node-id=my-node-0 \
    --object-store=file \
    --data-dir=/var/lib/influxdb3/data \
    --plugin-dir=/var/lib/influxdb3/plugins

InfluxDB 3 Core starts with:

• Data persistence at /var/lib/influxdb3/data
• Python processing engine enabled with plugin directory
• HTTP API listening on port 8181

Using InfluxDB 3 Core

After starting your InfluxDB 3 server, follow the Get Started guide to create an authorization token and start writing, querying, and processing data via the built-in influxdb3 CLI or the HTTP API.

Recommended tools for InfluxDB 3 Core

Use the following tools with InfluxDB 3 Core:

• InfluxDB 3 Explorer UI: Visualize, query, and manage your data with the standalone web interface designed for InfluxDB 3. View on Docker Hub
• Telegraf: Collect, transform, and send metrics from hundreds of sources directly to InfluxDB 3. View on Docker Hub
• Official Client Libraries: Integrate InfluxDB 3 into your applications using supported libraries for Python, Go, JavaScript, and more.

Customize server options

Customize your instance with available server options:

   docker run --rm %%IMAGE%%:3-core influxdb3 serve --help

Version compatibility

Migration paths

To migrate from v1 or v2 to InfluxDB 3:

1. Dual-write new data to v1/v2 and InfluxDB 3.
2. Query historical data from v1/v2 and write it to InfluxDB 3. InfluxDB 3 Enterprise is recommended for historical query capability.

Using InfluxDB v2

InfluxDB v2 is a previous version. Consider InfluxDB 3 Core for new deployments.

Enter the following command to start InfluxDB v2 initialized with custom configuration:

docker run -d -p 8086:8086 \
  -v $PWD/data:/var/lib/influxdb2 \
  -v $PWD/config:/etc/influxdb2 \
  -e DOCKER_INFLUXDB_INIT_MODE=setup \
  -e DOCKER_INFLUXDB_INIT_USERNAME=my-user \
  -e DOCKER_INFLUXDB_INIT_PASSWORD=my-password \
  -e DOCKER_INFLUXDB_INIT_ORG=my-org \
  -e DOCKER_INFLUXDB_INIT_BUCKET=my-bucket \
  %%IMAGE%%:2

After the container starts, visit http://localhost:8086 to view the UI.

For detailed instructions, see the InfluxDB v2 Docker Compose documentation.

Using InfluxDB v1

InfluxDB v1 is a previous version. Consider InfluxDB 3 Core for new deployments.

docker run -d -p 8086:8086 \
  -v $PWD:/var/lib/influxdb \
  %%IMAGE%%:1.11

This starts InfluxDB v1 with:

• HTTP API on port 8086
• Data persisted to current directory

For more information, see the InfluxDB v1 Docker documentation. For v1 Enterprise installation, see the InfluxDB Enterprise v1 documentation.
