HashiCorp Vault is a tool designed to securely store and manage sensitive information such as secrets, tokens, passwords, and encryption keys. It provides a unified interface to access different secret backends and offers a robust system for managing access to these secrets through policies and tokens.
When using HashiCorp Vault, you might encounter an error stating that a token is not renewable. This typically occurs when attempting to renew a token that has not been configured to support renewal. The error message might look like this:
"Error: token not renewable"
Tokens in Vault are used to authenticate and authorize access to secrets. Each token has specific properties, including whether it is renewable. A non-renewable token cannot have its lifespan extended, which means once it expires, a new token must be generated. This is often due to the token being created with the renewable
flag set to false
.
To determine if a token is renewable, you can inspect its properties using the Vault CLI:
vault token lookup <token>
Look for the renewable
field in the output. If it is set to false
, the token cannot be renewed.
If you need a renewable token, follow these steps to resolve the issue:
To create a new token that is renewable, use the following command:
vault token create -policy=<policy_name> -renewable=true
Replace <policy_name>
with the appropriate policy name for your use case.
After creating the new token, verify its properties to ensure it is renewable:
vault token lookup <new_token>
Check that the renewable
field is set to true
.
Once you have a renewable token, you can renew it using:
vault token renew <new_token>
This command will extend the token's lifespan according to its configured TTL (Time to Live).
