Option environment variables

You can use environment variables to define most influxdb3 serve options. For more information, see Configuration options.

Examples

In the examples below, replace my-host-01: with a unique string that identifies your InfluxDB 3 Core server.

Run the InfluxDB 3 server

influxdb3 serve \
  --object-store file \
  --data-dir ~/.influxdb3 \
  --node-id 
my-host-01
  • Copy
  • Fill window

Run the InfluxDB 3 server with extra verbose logging

influxdb3 serve \
  --verbose \
  --object-store file \
  --data-dir ~/.influxdb3 \
  --node-id 
my-host-01
  • Copy
  • Fill window

Run InfluxDB 3 with debug logging using LOG_FILTER

LOG_FILTER=debug influxdb3 serve \
  --object-store file \
  --data-dir ~/.influxdb3 \
  --node-id 
my-host-01
  • Copy
  • Fill window

Troubleshooting

Common Issues

  • Error: “Failed to connect to object store”
    Verify your --object-store setting and ensure all required parameters for that storage type are provided.

  • Permission errors when using S3, Google Cloud, or Azure storage
    Check that your authentication credentials are correct and have sufficient permissions.
