Give agentic workloads domain-scoped kubernetes credentials so they stop needing cluster-admin/root. Adds four least-privilege kubernetes secret engine roles, an `agents` AppRole (role_id-only, CIDR-bound to the agent workstation) that can mint them, and a write-capable KV grant for the kubernetes secrets subtree. - Add kubernetes_secret_backend_role configs agent-dhcp/dns/certs/storage with generated_role_rules scoping each to its operator CRDs + pod/log reads. - Add creds policies for each role, bound to Ben's cluster-operator ldap group (human kubectl use) and the agents AppRole (programmatic use). - Add the `agents` AppRole: bind_secret_id false, token_bound_cidrs 10.10.12.200/32, deterministic role_id, 1h/4h TTLs. - Add kv/kubernetes/agents policy granting the AppRole create/read/update/list on the kubernetes KV subtree (no delete).

terraform-vault
A repository to manage the configuration of Vault secret engines, authentication modes and policies.
Usage
- Initialize Terraform
Once you have your backend block configured, you need to initialize your Terraform working directory to configure the backend:
terraform init
This command initializes the backend and checks the connection to Consul. If everything is set up correctly, Terraform will start using Consul as its backend for storing the state.
- Common terraform init Errors
If you encounter errors while running terraform init, check the following:
Consul server is reachable: Make sure that the address is correct and that you can connect to the Consul server.
Consul token (if using ACLs): Verify that the token has the correct permissions to write to the specified path in the Consul KV store.
- Example Consul KV Structure
In Consul, the state file will be stored in the KV store under the specified path:
terraform/state
You can check the Consul KV store by accessing the Consul UI or using the consul kv command to see the stored Terraform state:
consul kv get terraform/state
