GCP Compute Target Pool

A Google Cloud Compute Target Pool is a regional grouping of VM instances that acts as the backend for the legacy TCP/UDP network load balancer. The pool defines which instances receive traffic, the optional session-affinity policy, the associated health checks that determine instance health, and an optional fail-over target pool for backup. See the official documentation for full details: https://cloud.google.com/compute/docs/reference/rest/v1/targetPools

Terrafrom Mappings:

  • google_compute_target_pool.id

Supported Methods​

  • GET: Get a gcp-compute-target-pool by its "name"
  • LIST: List all gcp-compute-target-pool
  • SEARCH: Search with full ID: projects/[project]/regions/[region]/targetPools/[name] (used for terraform mapping).

gcp-compute-health-check​

A target pool may reference one or more health checks through its healthChecks field. These health checks are used by Google Cloud to probe the instances in the pool and decide whether traffic should be sent to a particular VM.

gcp-compute-instance​

Each target pool contains a list of VM instances (instances field) that will receive load-balanced traffic. Overmind links the pool to every instance it contains.

gcp-compute-target-pool​

A target pool can specify another target pool as its backupPool to provide fail-over capacity, and it can itself be referenced as a backup by other pools. Overmind surfaces these peer-to-peer relationships between target pools.
