Init Command

The init command creates example job scaling and worker pool scaling meta documents in the current directory. These files provide a starting example for configuring both scaling functionalities.

General Options

• -job-scaling: Write a file which contains example job scaling configuration. This can be used directly within the Nomad job specification file to enable scaling for the desired job group.

• -cluster-scaling: Write a file which contains example cluster scaling configuration. This can be adapted to your configuration management to enable cluster scaling.

Examples

$ replicator init
Example scaling configuration written to job_scaling.hcl
Example scaling configuration written to cluster_scaling.hcl

The job_scaling.hcl file look like:

meta {
  "replicator_cooldown"         = 50
  "replicator_enabled"          = true
  "replicator_max"              = 10
  "replicator_min"              = 1
  "replicator_notification_uid" = "REP1"
  "replicator_scalein_mem"      = 30
  "replicator_scalein_cpu"      = 30
  "replicator_scaleout_mem"     = 80
  "replicator_scaleout_cpu"     = 80
}

The cluster_scaling.hcl looks like:

meta {
  "replicator_cool_down"            = 400
  "replicator_enabled"              = true
  "replicator_max_size"             = 10
  "replicator_min_size"             = 5
  "replicator_node_fault_tolerance" = 1
  "replicator_notification_uid"     = "REP2"
  "replicator_region"               = "us-east-1"
  "replicator_retry_threshold"      = 3
  "replicator_scaling_threshold"    = 3
  "replicator_worker_pool"          = "container-node-public-prod"
}
