# Note this forcefully removes a node from the cluster. Make sure all worker nodes
|
|
# have been removed before managers
|
|
#
|
|
# @param init
|
|
# This creates the first worker node for a new cluster.
|
|
# Set init to true to create a new cluster
|
|
#
|
|
# @param join
|
|
# This adds either a worker or manger node to the cluster.
|
|
# The role of the node is defined by the join token.
|
|
# Set to true to join the cluster
|
|
#
|
|
# @param advertise_addr
|
|
# The address that your node will advertise to the cluster for raft.
|
|
# On multihomed servers this flag must be passed
|
|
#
|
|
# @param autolock
|
|
# Enable manager autolocking (requiring an unlock key to start a stopped manager)
|
|
#
|
|
# @param cert_expiry
|
|
# Validity period for node certificates (ns|us|ms|s|m|h) (default 2160h0m0s)
|
|
#
|
|
# @param default_addr_pool
|
|
# Array of default subnet pools for global scope networks (['30.30.0.0/16','40.40.0.0/16'])
|
|
#
|
|
# @param default_addr_pool_mask_length
|
|
# Default subnet pools mask length for default-addr-pools (CIDR block number)
|
|
#
|
|
# @param dispatcher_heartbeat
|
|
# Dispatcher heartbeat period (ns|us|ms|s|m|h) (default 5s)
|
|
#
|
|
# @param external_ca
|
|
# Specifications of one or more certificate signing endpoints
|
|

|
|
# @param force_new_cluster
|
|
# Force create a new cluster from current state
|
|
#
|
|
# @param listen_addr
|
|
# The address that your node will listen to the cluster for raft.
|
|
# On multihomed servers this flag must be passed
|
|
#
|
|
# @param max_snapshots
|
|
# Number of additional Raft snapshots to retain
|
|
#
|
|
# @param snapshot_interval
|
|
# Number of log entries between Raft snapshots (default 10000)
|
|
#
|
|
# @param token
|
|
# The authentication token to join the cluster. The token also defines the type of
|
|
# node (worker or manager)
|
|
#
|
|
# @param manager_ip
|
|
# The ip address of a manager node to join the cluster.
