 In order to authentify against the Kubernetes API we need to provide the Admiralty `Source` with a token stored in a secret. This token is created on the `Target` for the `serviceAccount` that we will use in the Admiralty communication. After copying it, we replace the IP in the `kubeconfig` with the IP that will be targeted by the source to reach the k8s API. The token generated for the serviceAccount is added in the "user" part of the kubeconfig.

It is presented to the the k8s API on the target cluster, first as part of the TLS handshake and then to authenticate the serviceAccount that performs the pods delegation.

 When coupling Argo Workflows with a MinIO server to store the artifacts produced by a pod we need to access, for example but not only, a secret containing the authentication data. If we launch a workflow on cluster A and B, the secret resource containing the auth. data can't have the same thing in cluster A and B.
