|---|---|---|
-H | --host | Host URL of the running InfluxDB 3 Enterprise server (default is http://127.0.0.1:8181) |
--retention-period | Database retention period (duration value, for example: 30d, 24h, 1h) | |
--token | Authentication token | |
--tls-ca | Path to a custom TLS certificate authority (for self-signed or internal certificates) | |
--tls-no-verify | Disable TLS certificate verification. Not recommended in production. Useful for testing with self-signed certificates | |
-h | --help | Print help information |
--help-all | Print detailed help information |
Option environment variables
You can use the following environment variables instead of providing CLI options directly:

INFLUXDB3_HOST_URL | --host |
INFLUXDB3_AUTH_TOKEN | --token |
INFLUXDB3_TLS_NO_VERIFY | --tls-no-verify |
Examples
The following examples show how to create a database.
In the examples below, replace the following:
DATABASE_NAME: Database nameAUTH_TOKEN: Authentication token
Create a database (default)
Creates a database using settings from environment variables and defaults.
influxdb3 create database DATABASE_NAMECreate a database with an authentication token
Creates a database using the specified arguments. Flags override their associated environment variables.
influxdb3 create database --token AUTH_TOKEN DATABASE_NAMECreate a database with a retention period
Creates a database with a 30-day retention period. Data older than 30 days will not be queryable.
influxdb3 create database --retention-period 30d DATABASE_NAMECreate a database with infinite retention
Creates a database with no retention period (data never expires).
influxdb3 create database --retention-period none DATABASE_NAMECreate a database with a 90-day retention period
Creates a database with a 90-day retention period using an authentication token.
influxdb3 create database \
--retention-period 90d \
--token AUTH_TOKEN \
DATABASE_NAMECreate a database with a 1-year retention period
Creates a database with a 1-year retention period.
influxdb3 create database --retention-period 1y DATABASE_NAMECreate a database with a combined duration
Creates a database with a retention period of 30 days and 12 hours.
influxdb3 create database --retention-period 30d12h DATABASE_NAMERetention period duration formats
Retention periods are specified as duration values using a numeric value plus a duration unit.
Valid duration units
| Unit | Description |
|---|---|
h | hour |
d | day |
w | week |
mo | month (30 days) |
y | year (365 days) |
Minute (m) and second (s) units are not supported for retention periods.
Retention period constraints
- Minimum for data retention: The practical minimum retention period is 1 hour (
1h). - Zero-duration periods: Setting a retention period to
0<unit>(for example,0dor0h) is allowed but marks all data for immediate deletion at query time. This differs from InfluxDB 1.x and 2.x where0dmeant infinite retention. - Infinite retention: Use
noneto set an infinite retention period.
Example duration values
1h- 1 hour24h- 24 hours7d- 7 days4w- 4 weeks30d- 30 days1mo- 1 month (30 days)90d- 90 days1y- 1 year (365 days)none- infinite (data never expires)
You can combine units: 30d12h (30.5 days), 1y6mo (545 days)
