eCommerce policy. We’ll cover:
- Reviewing existing ACL policies
- Creating a new token
- Automating token generation
1. Review Existing Policies
Before assigning a token, confirm which ACL policies exist in your Consul cluster.Attempting to list policies without a valid token will result in a permission error.
Sample Output
2. Create a New Token
Now generate a scoped ACL token bound to youreCommerce policy. Replace the -policy-id value with the actual Policy ID obtained above.
Expected Response
SecretID value is the actual token you will configure on web-server-01 for secure Consul access.
3. Automating Token Generation
For large-scale or production environments, manual token creation can become error-prone. Consider using HashiCorp Vault’s Consul secrets engine to dynamically issue ACL tokens:- Define roles in Vault that map to Consul policies.
- Vault will automatically provision short-lived tokens.
- Centralize token lifecycle management and auditing.
Dynamic token issuance reduces manual errors, enforces least privilege, and simplifies rotation.
