sealctl token command is primarily used to generate a token for connecting master and worker nodes in a Kubernetes cluster. In a Kubernetes cluster, when you want to add a new worker node, you typically need to provide a token for authentication. This token ensures that only worker nodes with the correct token can join the cluster.
sealctl token command generates a token for authentication by accepting a configuration file (optional) and a certificate key (optional) as parameters. By default, if no configuration file and certificate key are provided, the command uses built-in default settings to generate the token.
In summary, the
sealctl token command is used to generate a token for authentication, allowing worker nodes to securely join a Kubernetes cluster. Using this command simplifies the process of adding nodes to the cluster and ensures the security of the cluster.
