You need to connect to and manage a new HCP Vault cluster using the Vault...

Comprehensive and Detailed in Depth Explanation:

To connect to an HCP Vault cluster using the Vault CLI, you need to set VAULT_ADDR and VAULT_NAMESPACE . The HashiCorp Vault documentation states: " You can use environment variables to configure the CLI globally. For example, export VAULT_ADDR= ' http://localhost:8200 ' sets the address of your Vault server globally. " For HCP Vault, the default port is 8200, and the default namespace is " admin, " so VAULT_ADDR=https:// < cluster-address > :8200 and VAULT_NAMESPACE=admin are required. A token (via VAULT_TOKEN) is also needed for authentication but is typically set after initial connectivity.

VAULT_CLIENT_KEY isn’t a standard variable for CLI connectivity. VAULT_REDIRECT_ADDR and VAULT_CLUSTER_ADDR are not used for this purpose. Thus, C provides the correct variables.
