Manage Client Keys

[edit on GitHub]

A client is an actor that has permission to access the Chef Infra Server. A client is most often a node (on which the Chef Infra Client runs), but is also a workstation (on which knife runs), or some other machine that is configured to use the Chef Infra Server API. Each request to the Chef Infra Server that is made by a client uses a private key for authentication that must be authorized by the public key on the Chef Infra Server.

Use the Chef management console to create a key pair, download the private key, and then set permissions, to delete a key, or to reset a key.

chef-validator Keys

Every request made by Chef Infra Client to the Chef Infra Server must be an authenticated request using the Chef Infra Server API and a private key. When Chef Infra Client makes a request to the Chef Infra Server, Chef Infra Client authenticates each request using a private key located in /etc/chef/client.pem.

However, during the first Chef Infra Client run, this private key does not exist. Instead, Chef Infra Client attempts to use the private key assigned to the chef-validator, located in /etc/chef/validation.pem. (If, for any reason, the chef-validator is unable to make an authenticated request to the Chef Infra Server, the initial Chef Infra Client run will fail.)

During the initial Chef Infra Client run, Chef Infra Client registers itself with the Chef Infra Server using the private key assigned to the chef-validator, after which Chef Infra Client will obtain a client.pem private key for all future authentication requests to the Chef Infra Server.

After the initial Chef Infra Client run has completed successfully, the chef-validator is no longer required and may be deleted from the node. Use the delete_validation recipe found in the chef-client cookbook (https://github.com/chef-cookbooks/chef-client) to remove the chef-validator.
