trustd

Security is one of the highest priorities within Talos. To run a Kubernetes cluster a certain level of trust is required to operate a cluster. For example, orchestrating the bootstrap of a highly available control plane requires the distribution of sensitive PKI data.

To that end, we created trustd. Based on the concept of a Root of Trust, trustd is a simple daemon responsible for establishing trust within the system. Once trust is established, various methods become available to the trustee. It can, for example, accept a write request from another node to place a file on disk.

Additional methods and capability will be added to the trustd component in support of new functionality in the rest of the Talos environment.
