terraform-aws-s3-loader-kinesis-ec2

A Terraform module which deploys a Snowplow S3 Loader application on AWS running on top of EC2. If you want to use a custom AMI for this deployment you will need to ensure it is based on top of Amazon Linux 2.

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

An S3 Loader requires an input stream, an output stream for corrupted data that cannot be saved to S3 and an S3 bucket to save the data into.

module "s3_pipeline_bucket" {
  source  = "snowplow-devops/s3-bucket/aws"
  version = "0.2.0"

  bucket_name = "your-bucket-name"
}

module "enriched_stream" {
  source  = "snowplow-devops/kinesis-stream/aws"
  version = "0.2.0"

  name = "enriched-stream"
}

module "bad_1_stream" {
  source  = "snowplow-devops/kinesis-stream/aws"
  version = "0.2.0"

  name = "bad-1-stream"
}

module "s3_loader_enriched" {
  source = "snowplow-devops/s3-loader-kinesis-ec2/aws"

  accept_limited_use_license = true

  name             = "s3-loader-enriched-server"
  vpc_id           = var.vpc_id
  subnet_ids       = var.subnet_ids
  in_stream_name   = module.enriched_stream.name
  bad_stream_name  = module.bad_1_stream.name
  s3_bucket_name   = module.s3_pipeline_bucket.id
  s3_object_prefix = "enriched/"

  ssh_key_name     = "your-key-name"
  ssh_ip_allowlist = ["0.0.0.0/0"]
}
