terraform-google-enrich-pubsub-ce

A Terraform module which deploys the Snowplow Enrich PubSub service on Compute Engine. If you want to use a custom image for this deployment you will need to ensure it is based on top of Ubuntu 20.04.

Telemetry

This module by default collects and forwards telemetry information to Snowplow to understand how our applications are being used. No identifying information about your sub-account or account fingerprints are ever forwarded to us - it is very simple information about what modules and applications are deployed and active.

If you wish to subscribe to our mailing list for updates to these modules or security advisories please set the user_provided_id variable to include a valid email address which we can reach you at.

How do I disable it?

To disable telemetry simply set variable telemetry_enabled = false.

Usage

Standard usage

Enrich PubSub takes data from a raw input topic and pushes validated data to the enriched topic and failed data to the bad topic. As part of this validation process we leverage Iglu which is Snowplow's schema repository - the home for event and entity definitions. If you are using custom events that you have defined yourself you will need to ensure that you link in your own Iglu Registries to this module so that they can be discovered correctly.

By default this module enables 5 enrichments which you can find in the templates/enrichments directory of this module.

module "raw_topic" {
  source  = "snowplow-devops/pubsub-topic/google"
  version = "0.3.0"

  name = "raw-topic"
}

module "bad_1_topic" {
  source  = "snowplow-devops/pubsub-topic/google"
  version = "0.3.0"

  name = "bad-1-topic"
}

module "enriched_topic" {
  source  = "snowplow-devops/pubsub-topic/google"
  version = "0.3.0"

  name = "enriched-topic"
}

module "enrich_pubsub" {
  source = "snowplow-devops/enrich-pubsub-ce/google"

  accept_limited_use_license = true

  name = "enrich-server"

  network    = var.network
  subnetwork = var.subnetwork
  region     = var.region

  raw_topic_name = module.raw_topic.name
  good_topic_id  = module.enriched_topic.id
  bad_topic_id   = module.bad_1_topic.id

  ssh_key_pairs    = []
  ssh_ip_allowlist = ["0.0.0.0/0"]

  # Linking in the custom Iglu Server here
  custom_iglu_resolvers = [
    {
      name            = "Iglu Server"
      priority        = 0
      uri             = "http://your-iglu-server-endpoint/api"
      api_key         = var.iglu_super_api_key
      vendor_prefixes = []
    }
  ]
}

Inserting custom enrichments

To define your own enrichment configurations you will need to provide the enrichment in the appropriate placeholder.

locals {
  enrichment_anon_ip = <<EOF
{
  "schema": "iglu:com.snowplowanalytics.snowplow/anon_ip/jsonschema/1-0-1",
  "data": {
    "name": "anon_ip",
    "vendor": "com.snowplowanalytics.snowplow",
    "enabled": true,
    "parameters": {
      "anonOctets": 1,
      "anonSegments": 1
    }
  }
}
EOF
}

module "enrich_pubsub" {
  source = "snowplow-devops/enrich-pubsub-ce/google"

  accept_limited_use_license = true

  name = "enrich-server"

  network    = var.network
  subnetwork = var.subnetwork
  region     = var.region

  raw_topic_name = module.raw_topic.name
  good_topic_id  = module.enriched_topic.id
  bad_topic_id   = module.bad_1_topic.id

  ssh_key_pairs    = []
  ssh_ip_allowlist = ["0.0.0.0/0"]

  # Linking in the custom Iglu Server here
  custom_iglu_resolvers = [
    {
      name            = "Iglu Server"
      priority        = 0
      uri             = "http://your-iglu-server-endpoint/api"
      api_key         = var.iglu_super_api_key
      vendor_prefixes = []
    }
  ]

  # Enable this enrichment
  enrichment_anon_ip = local.enrichment_anon_ip
}

Disabling default enrichments

As with inserting custom enrichments to disable the default enrichments a similar strategy must be employed. For example to disable YAUAA you would do the following.

locals {
  enrichment_yauaa = <<EOF
{
  "schema": "iglu:com.snowplowanalytics.snowplow.enrichments/yauaa_enrichment_config/jsonschema/1-0-0",
  "data": {
    "enabled": false,
    "vendor": "com.snowplowanalytics.snowplow.enrichments",
    "name": "yauaa_enrichment_config"
  }
}
EOF
}

module "enrich_pubsub" {
  source = "snowplow-devops/enrich-pubsub-ce/google"

  accept_limited_use_license = true

  name = "enrich-server"

  network    = var.network
  subnetwork = var.subnetwork
  region     = var.region

  raw_topic_name = module.raw_topic.name
  good_topic_id  = module.enriched_topic.id
  bad_topic_id   = module.bad_1_topic.id

  ssh_key_pairs    = []
  ssh_ip_allowlist = ["0.0.0.0/0"]

  # Linking in the custom Iglu Server here
  custom_iglu_resolvers = [
    {
      name            = "Iglu Server"
      priority        = 0
      uri             = "http://your-iglu-server-endpoint/api"
      api_key         = var.iglu_super_api_key
      vendor_prefixes = []
    }
  ]

  # Disable this enrichment
  enrichment_yauaa_enrichment_config = local.enrichment_yauaa
}
