STS Operator

Sts Operator, runs in sts-silicom namespace, manages cluster wide STS configurations. It offers StsConfig and StsOperatorConfig CRDs and creates tsyncd to apply node specific STS config.

STS Plugin daemonset (feature.node.kubernetes.io/custom-silicom.sts.devices: "true")

Once NFD operator has labelled the nodes, this daemonset queries the network interfaces and STS specific information and accordingly labels the nodes.

STS daemonset (sts.silicom.com/config: "gm-1")

This consists of the following daemons on labelled nodes, all of these running in the same pod. Nodes labelled with the

• tsyncd
• GPSd (if in T-GM.8275.1 mode)
• ts2phcs
• phc2sys
• grpc-tsyncd
