Functions ¶

Types ¶
type Cluster ¶ added in v0.12.0
type Cluster struct { StaticNodes []string `json:"staticnodes"` BootNodes []string `json:"bootnodes"` MailServers []string `json:"mailservers"` // list of trusted mail servers RendezvousNodes []string `json:"rendezvousnodes"` }
Cluster defines a list of Ethereum nodes.
type ClusterConfig ¶
type ClusterConfig struct { // Enabled flag specifies that nodes in this configuration are taken into account. Enabled bool // Fleet is a name of a selected fleet. If it has a value, nodes are loaded // from a file, namely `fleet-*.{{ .Fleet }}.json`. Nodes can be added to any list // in `ClusterConfig`. Fleet string // StaticNodes is a list of static nodes. StaticNodes []string // BootNodes is a list of bootnodes. BootNodes []string // TrustedMailServers is a list of verified and trusted Mail Server nodes. TrustedMailServers []string // RendezvousNodes is a list rendezvous discovery nodes. RendezvousNodes []string }
