Description

Add support for S3ObjectAcl [1] in the aws_acmpca_certificate_authority resource.

When we configure an ACM PCA we can use the revocation_configuration to provide an S3 bucket, where the ACM PCA service can put the relevant CRLs.

As mentioned in the docs, by default the CRLs are copied with a PUBLIC_READ ACL, which can cause a problem when the bucket has Block Public Access enabled.

New or Affected Resource(s)

• aws_acmpca_certificate_authority

Potential Terraform Configuration

  bucket = aws_s3_bucket.root_ca_revoc.id

  block_public_acls       = true
  ignore_public_acls      = true
  block_public_policy     = true
  restrict_public_buckets = true
}

  certificate_authority_configuration {
    key_algorithm     = "RSA_4096"
    signing_algorithm = "SHA256WITHRSA"

    subject {
      country             = "GB"
      organization        = "Org"
      organizational_unit = "OrgUnit"
      common_name         = "name.orgunit.org"
    }
  }

  revocation_configuration {
    crl_configuration {
      enabled            = true
      expiration_in_days = 30
      s3_bucket_name     = aws_s3_bucket.root_ca_revoc.id
      s3_object_acl     = "BUCKET_OWNER_FULL_CONTROL"
    }
