#TACKLE APP CHEF HOW TO#
How to manage the SecretID and the Token to create the SecretID I will introduce the merits to create the RoleID and SecretID by different two channels later. The actual channel can be freely chosen by the users depending on the current users’ system tooling. After that, the application will get the Vault Token to access the Secret Engines. These two IDs are recommended to be created in the different channel.įor example, RoleID is pulled when Virtual Machine is provisioned and injected into the filesystem or system environment, on the other hand, SecretID is pulled when the Server configuration like by Chef.Īnd when the application is booted, this application will use both of the RoleID and Secret ID to request authentication to Vault. $ vault read auth/approle/role/kv-full-role/role-id $ vault write -f auth/approle/role/kv-full-role/secret-idĬlients will get the SecretID and RoleID by the commands above. The usual and secure way is using “pull mode” which is for dynamically pulling the these IDs from Vault.įollowing the sample commands to pull the IDs. The important things are “How” and Where” they should be generated. The best way of generating the SecretID is by orchestrator like Chef, Ansible and Terraform. Each client should have the unique SecretID. It’s not handled as sensitive data and can be set into the configuration files and environment variables. When the clients are authenticated by the RoleID and SecretID which are based the above role, they would have the token having the permissions to access the KV Secret Engine. $ vault policy write kv-full-role kv-full-policy.hcl path "kv/*" īy CLI, this policy can be applied to define the Role. Role is created by describing policy like this. Generated Vault Token has the rights based on the Role. RoleID and SecretID are associated with the Role. In the end, client asks to login to the Vault like hitting following API. Using AppRoleĪppRole is one of the ways to authenticate clients and used mainly by machines.įor AppRole, clients can be authenticated and get the Vault Token only when they have the appropriate set of the RoleID and SecretID. This article introduces AppRole authentication to tackle this problem. This hurdle is called as “Secret Zero Problem”. In this way, users need to consider how to securely deal with the first secret and token.
And also, if users use the cloud keys and certifications, of course they should be handled pretty carefully. On the other hand, to authenticate the clients, Vault requires the API token to hit the authenticate endpoint.

Vault supports various ways of authentication for the machines like software and servers.
Usually, token should not be injected directly into such as the configuration files and should be issued after authentication. Using the Vault from clients, clients like applications and CI tools need to take the Vault’s API Token before calling the Vault API to generate (or get) the secrets via Vault Secret Engine.įor instance, when an application would like to ask Vault to generate the AWS secret, the application is required to set the Vault Token for its API call, which has the right to request Vault to generate the AWS secret, Clients especially software based ones need to have the Vault Token into their environments somehow. HashiCorp Vault allows the users to keep the environment secure by its static and dynamic secrets management capability.
