Start {{% product-name %}} with a preconfigured "offline" admin token file. If no admin tokens already exist, InfluxDB automatically creates an admin token using the provided admin token file. Offline tokens are designed to help with automated deployments.

• Generate an offline admin token file
  • Offline admin token file schema
• Start InfluxDB with the preconfigured admin token

Generate an offline admin token file

Use the influxdb3 create token --admin command to generate an offline admin token file. Include the following options:

{{% req type="key" %}}

• --name: The name of the admin token (default is _admin) (replace {{% code-placeholder-key %}}TOKEN_NAME{{% /code-placeholder-key %}})
• --expiry: Duration for the token to remain valid, in humantime format (for example, 10d for 10 days or 1y for 1 year). (replace {{% code-placeholder-key %}}DURATION{{% /code-placeholder-key %}})
• {{% req "*" %}} --offline
• {{% req "*" %}} --output-file: File path to use for the generated token file (replace {{% code-placeholder-key %}}path/to/tokens.json{{% /code-placeholder-key %}})

influxdb3 create token --admin \
  --name TOKEN_NAME \
  --expiry DURATION \
  --offline \
  --output-file path/to/admin-token.json

[!Note]

You can write or generate your own admin token file

The influxdb3 create token --admin --offline command makes generating offline admin token files easy, but it is not required. You can also write or generate your own admin token files using the required JSON schema.

Token string security standards

If writing or generating your own admin token file, ensure that the token string is sufficiently secure. We recommend the following:

• Use a cryptographically secure pseudorandom number generator.
• Ensure sufficient length and entropy. Generate and base64-encode a random string of at least 16 bytes (128 bits).
• Prepend the generated string with apiv3_ for InfluxDB compatibility.

[!Important]

Token file permissions

Token file permissions should be restricted 0600 to protect the token.

Offline admin token file schema

An offline admin token file is a JSON-formatted file that contains a single object with the following fields:

• token: The raw token string (must begin with apiv3_)
• name: The token name (default is _admin)
• expiry_millis: (Optional) Token expiration time as a millisecond Unix timestamp

{
  "token": "apiv3_0XXXX-xxxXxXxxxXX_OxxxX...",
  "name": "_admin",
  "expiry_millis": 1756400061529
}

Start InfluxDB with the preconfigured admin token

When starting {{% product-name %}}, include the --admin-token-file option with the influxdb3 serve command or set the INFLUXDB3_ADMIN_TOKEN_FILE environment variable to provide the preconfigured offline admin token file:

{{< code-tabs-wrapper >}} {{% code-tabs %}} CLI option Environment variable {{% /code-tabs %}} {{% code-tab-content %}}

influxdb3 serve \
  # ... \
  --admin-token-file path/to/admin-token.json

{{% /code-tab-content %}} {{% code-tab-content %}}

INFLUXDB3_ADMIN_TOKEN_FILE=path/to/admin-token.json

influxdb3 serve \
  # ... \

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

When the server starts, you can use the preconfigured admin token to interact with your {{% product-name %}}{{% show-in "enterprise" %}} cluster or{{% /show-in %}} instance.
