Dataset/Scalyr Terraform Provider (proof-of-concept)

Inspired by https://github.com/ansoni/terraform-provider-scalyr

The provider is used to interact with the resources supported by Dataset and its API. The provider needs to be configured with the proper access key with write permissions before it can be used. It requires terraform 0.12 or later. See ./terraform/providers.tf for configuration example.

TODO next:

1. Add provider resources' tests
2. Support configuration of Scalyr dashboards

Currently supported methods and resources (see ./terraform/main.tf)

1. DataSet's Alerts feature

• Alert as a single resource.

    resource "scalyr_alert_rule" "test_alert_rule_1" {
      description              = "Test Alert Rule #1"
      alert_address            = [
          "my_email_addr_1@something.com",
          "my_email_addr_2@something.com"
      ]
      grace_period_minutes     = 0
      renotify_period_minutes  = 60
      resolution_delay_minutes = 0
      trigger                  = "count:5 minutes(test) > 0"
    }

• Alert group sharing the same e-mail address.

    resource "scalyr_alert_group" "test_alert_group" {
      description   = "Test Alert Group #1"
      alert_address = ["my_email_addr_1@something.com"]

      alert_rule {
        description              = "Test Nested Alert Rule #1"
        grace_period_minutes     = 0
        renotify_period_minutes  = 30
        resolution_delay_minutes = 0
        trigger                  = "count:5 minutes(test) > 0"
      }

      alert_rule {
        description              = "Test Nested Alert Rule #2"
        grace_period_minutes     = 0
        renotify_period_minutes  = 60
        resolution_delay_minutes = 0
        trigger                  = "count:2 minutes(test) > 0"
      }
    }

• Alert with JSON definition (useful to set silence rules that are currently not supported along with host templating)

    resource "scalyr_alert_rule_json" "test_alert_rule_2" {
      description = "Test Alert Rule #2"
      json = jsonencode({
        trigger                = "count:60 minutes(test) > 0"
        gracePeriodMinutes     = 0
        renotifyPeriodMinutes  = 60
        resolutionDelayMinutes = 30
      })
    }

2. Configuration files set by /api/getFile and api/putFile. This makes alert templating very easy.

    resource "scalyr_config_file" "alerts" {
      file_path = "/scalyr/alerts"
      content   = <<EOF
    {
    "alertAddress": "",
    "alerts": [
        ${scalyr_alert_rule.test_alert_rule_1.json},
        ${scalyr_alert_group.test_alert_group.json},
        ${scalyr_alert_rule_json.test_alert_rule_2.json}
      ]
    }
    EOF
    }

Notes:

Need to check the issues with building the provider library on M1 machines. For now the easiest way to build/test it:

GOOS=linux GOARCH=amd64 go build -o terraform-provider-scalyr
docker run -it --rm -v "$PWD":/terraform --entrypoint /bin/sh hashicorp/terraform:0.14.7
cd terraform/terraform
mkdir -p ~/.terraform.d/plugins/terraform.local/local/scalyr/1.0.0/linux_amd64/
cp ../terraform-provider-scalyr ~/.terraform.d/plugins/terraform.local/local/scalyr/1.0.0/linux_amd64/terraform-provider-scalyr
rm -rf ./terraform.tfstate .terraform .terraform.
lock.hcl

terraform init
terraform plan
terraform apply
