Internal
Master Node
The master node runs, in order, these services:
The master daemon (or daemons) must be started after etcd is started, they depend on etcd. They are started before the node service.
etcd Daemon
Unit: etcd.service
Unit File: /usr/lib/systemd/system/etcd.service
Working Directory: /var/lib/etcd
Configuration File: /etc/etcd/etcd.conf
Process:
/usr/bin/etcd --name=master1.rdu20.internal --data-dir=/var/lib/etcd --listen-client-urls=https://192.199.0.199:2379
master Daemons
In a non-HA deployment, the master controller daemon and master api daemon and are coalesced in a single process. In HA environments, they are separated, so the master api daemon processes can be load-balanced among, while the master controller daemon run in an active/passive configuration, there is just one active master controller daemon instance in the cluster.
