Managing with Terraform

Terraform and has deepened its partnership with Hashicorp over the last few months. Recently, we announced our integration with their service mesh, Hashicorp Consul. Simultaneously, we have worked on and completed an integration with their infrastructure orchestrator (a.k.a, infrastructure-as-code or IAC), Terraform. IACs take manual configurations and treats them as, well, code (along with procedures, build guides, run books, etc.).

It is written in Hashicorp Language (HCL) and can build almost anything up to the servers themselves. This includes security objects, network objects, cloud networks, and scaling objects. Additionally, it provides automated feedback on your planned revisions before it runs. Other features, like Terragrunt, seek and highlight code duplication to help with efficiency.

Install Terraform

To install on MacOS with Homebrew, simply run:

$ brew install hashicorp/tap/terraform

And confirm the installation by simply running terraform without arguments. This will also conveniently show you the list of the most common Terraform CLI commands ($ terraform -help will show the same result):

$ terraform
Usage: terraform [-version] [-help] <command> [args]

The available commands for execution are listed below.
The most common, useful commands are shown first, followed by
less common or more advanced commands. If you're just getting
started with Terraform, stick with the common commands. For the
other commands, please read the help and docs before usage.

Common commands:
    apply              Builds or changes infrastructure
    console            Interactive console for Terraform interpolations
    destroy            Destroy Terraform-managed infrastructure
    env                Workspace management
    fmt                Rewrites config files to canonical format
    get                Download and install modules for the configuration
    graph              Create a visual graph of Terraform resources
    import             Import existing infrastructure into Terraform
    init               Initialize a Terraform working directory
    login              Obtain and save credentials for a remote host
    logout             Remove locally-stored credentials for a remote host
    output             Read an output from a state file
    plan               Generate and show an execution plan
    providers          Prints a tree of the providers used in the configuration
    refresh            Update local state file against real resources
    show               Inspect Terraform state or plan
    taint              Manually mark a resource for recreation
    untaint            Manually unmark a resource as tainted
    validate           Validates the Terraform files
    version            Prints the Terraform version
    workspace          Workspace management

All other commands:
    0.12upgrade        Rewrites pre-0.12 module source code for v0.12
    0.13upgrade        Rewrites pre-0.13 module source code for v0.13
    debug              Debug output management (experimental)
    force-unlock       Manually unlock the terraform state
    push               Obsolete command for Terraform Enterprise legacy (v1)
    state              Advanced state management

You can also customize Terraform CLI commands by running:

$terraform -help -plan

#Note that Terraform CLI configuration is separate from infrastructure configuration. Additionally, there is a specific Terraform configuration language. API and the Provider for Terraform

Terraform operates its integrations on providers. These providers manage a set of resource types, usually linked to a given cloud or infrastructure service. The provider will connect Terraform with the API. Terraform can run any of the following four API endpoints:

You’ll need the Terraform CLI before getting started. Additionally, you will access your API token.

Next, download the Provider (and the JetBrains IDE HCL metadata for running the repo script. You’ll find it under ./scripts/
Then run:


#If you’re using a *nix style system, you can build from the project root. This will copy it into your plugins directory. Otherwise, you can copy it into your Terraform templates folder instead.

Using the Provider for Terraform

Next, configure the api_token and region fields. The API token is a requirement, while the two-letter region code identifies where your account is hosted. Those codes you can see in the chart below. Also look at the Docs for regions.

Here is an example of the provider configuration with both fields:

provider "logzio" {
  api_token = "<<token>>"
  region= "<<region>>" #e.g.

Replace {var.api_token} with your designated account API token (remember to ensure that if you’re using a sub account that you’re using that sub account’s token.

Creating a Slack Notification Endpoint

This example adds a brand new Slack notification channel for an existing alert. The example assumes triggers an alert whenever records 10 loglevel:ERROR messages in 10 minutes.

If you want to try out this example, you will need to first fill in the specifics for your account, including and provide your API token and base_url.

provider "logzio" {
  api_token = "<<token>>"
  region= "<<region>>"

resource "logzio_endpoint" "my_endpoint" {
  title = "my_endpoint"
  description = "my slack endpoint"
  endpoint_type = "slack"
  slack {
    url = "${var.slack_url}"

resource "logzio_alert" "my_alert" {
  title = "my_other_title"
  query_string = "loglevel:ERROR"
  operation = "GREATER_THAN"
  notification_emails = []
  search_timeframe_minutes = 10
  value_aggregation_type = "NONE"
  alert_notification_endpoints = ["${}"]
  suppress_notifications_minutes = 30
  severity_threshold_tiers {
      severity = "HIGH",
      threshold = 10
} and Hashicorp

With this integration, becomes an official provider of Terraform. It also complements tie-ins with Hashicorp Vault and service mesh Hashicorp Consul. Check back for more info on Logz integrations and logging tutorials.
