Configuring API tokens

Red Hat Advanced Cluster Security for Kubernetes (RHACS) requires API tokens for some system integrations, authentication processes, and system functions. You can configure tokens using the RHACS web interface.

Creating an API token

Procedure

  1. In the RHACS portal, navigate to Platform Configuration → Integrations.

  2. Scroll to the Authentication Tokens category, and then click API Token.

  3. Click Generate Token.

  4. Enter a name for the token and select a role that provides the required level of access (for example, Continuous Integration or Sensor Creator).

  5. Click Generate.

    Copy the generated token and securely store it. You will not be able to view it again.

About API token expiration

API tokens expire one year from the creation date. RHACS alerts you in the web interface and by sending log messages to Central when a token will expire in less than one week. The log message process runs once an hour. Once a day, the process lists the tokens that are expiring and creates a log message for each one. Log messages are issued once a day and appear in Central logs.

Logs have the format as shown in the following example:

Warn: API Token [token name] (ID [token ID]) will expire in less than X days.

You can change the default settings for the log message process by configuring the environment variables shown in the following table:
