Storage Bucket in DigitalOcean

The module creates an object storage bucket in DigitalOcean Spaces. Spaces Object Storage is an Amazon S3-compatible object storage service.

Allows configuring essential parameters:

toggle versioning
toggle access mode
attach externally defined JSON policies

NOTE: DigitalOcean has issues when creating policies for Spaces, similar to issues in older versions of S3 policies, with which Spaces is compatible. If there are multiple policies, the module automatically combines them into one.
See this issue in AWS Terraform provider

NOTE: DigitalOcean Spaces is compatible with Amazon S3. As a result, there is a limit of 20 KB to the length of a single policy.
See this Amazon S3 documentation article

Provision instructions

Initialize mandatory providers:

Copy and paste into your Terraform configuration and insert the variables:

 hclmodule "tf_do_spaces_bucket" {
  source  = "solutions.corewide.com/digitalocean/tf-do-spaces-bucket/digitalocean"
  version = "~> 1.0.0"

  # specify module inputs here or try one of the examples below
  ...
}

Initialize the setup:

 shellterraform init

Define update strategy

Corewide DevOps team strictly follows Semantic Versioning Specification to provide our clients with products that have predictable upgrades between versions. We recommend pinning patch versions of our modules using pessimistic constraint operator (~>) to prevent breaking changes during upgrades.

To get new features during the upgrades (without breaking compatibility), use ~> 1.0 and run terraform init -upgrade

For the safest setup, use strict pinning with version = "1.0.0"

v1.0.0 released 8 months, 2 weeks ago

Setup with custom configuration, versioning enabled, access_mode is private and a policy assigned:

 hclmodule "spaces" {
  source  = "solutions.corewide.com/digitalocean/tf-do-spaces-bucket/digitalocean"
  version = "~> 1.0"

  name        = "foo"
  region      = "fra1"
  access_mode = "private"
  versioning  = true

  bucket_policies = {
    policy-deny-delete-objects = jsonencode({
      Version = "2012-10-17"
      Statement = [
        {
          Effect    = "Deny"
          Principal = "*"

          Action = [
            "s3:DeleteObject",
          ]

          Resource = [
            "arn:aws:s3:::${module.spaces.bucket.name}/protected/*",
          ]
        }
      ]
    })

    policy-allow-read-write-bucket = jsonencode({
      Version = "2012-10-17"
      Statement = [
        {
          Effect    = "Allow"
          Principal = "*"

          Action = [
            "s3:GetObject",
            "s3:PutObject",
            "s3:DeleteBucket",
            "s3:ListBucket",
          ]

          Resource = [
            "arn:aws:s3:::${module.spaces.bucket.name}",
            "arn:aws:s3:::${module.spaces.bucket.name}/*",
          ]
        }
      ]
    })
  }
}

Minimal setup with default parameters:

 hclmodule "spaces" {
  source  = "solutions.corewide.com/digitalocean/tf-do-spaces-bucket/digitalocean"
  version = "~> 1.0"

  name   = "foo"
  region = "fra1"
}

Simple configuration with publicly accessible storage:

 hclmodule "spaces" {
  source  = "solutions.corewide.com/digitalocean/tf-do-spaces-bucket/digitalocean"
  version = "~> 1.0"

  name        = "foo"
  region      = "fra1"
  access_mode = "public-read"
}
