Alarms retrieves all alarms on a cluster.

func (*Client) Close Uses

func (c *Client) Close() error

Close closes the etcd client.

func (*Client) Members Uses

func (c *Client) Members(ctx context.Context) ([]*Member, error)

Members retrieves a list of etcd members.

func (*Client) MoveLeader Uses

func (c *Client) MoveLeader(ctx context.Context, newLeaderID uint64) error

func (c *Client) RemoveMember(ctx context.Context, id uint64) error

RemoveMember removes a given member.

func (*Client) UpdateMemberPeerURLs Uses

func (c *Client) UpdateMemberPeerURLs(ctx context.Context, id uint64, peerURLs []string) ([]*Member, error)

UpdateMemberPeerList updates the list of peer URLs

type GRPCDial Uses

type GRPCDial func(ctx context.Context, addr string) (net.Conn, error)

GRPCDial is a function that creates a connection to a given endpoint.

type Member Uses

type Member struct {
    // ClusterID is the ID of the cluster to which this member belongs
    ClusterID uint64

    // ID is the ID of this cluster member
    ID  uint64

    // Name is the human-readable name of the member. If the member is not started, the name will be an empty string.
    Name string

    // PeerURLs is the list of URLs the member exposes to the cluster for communication.
    PeerURLs []string

    // ClientURLs is the list of URLs the member exposes to clients for communication. If the member is not started, clientURLs will be empty.
    ClientURLs []string

    // IsLearner indicates if the member is raft learner.
    IsLearner bool

    // Alarms is the list of alarms for a member.
    Alarms []AlarmType
}
