Provision, change, and version resources on any environment.

To update or switch versions, run webi terraform@stable (or @v1.6.1, @beta, etc).


These are the files / directories that are created and/or modified with this install:


Cheat Sheet

With HashiCorp Terraform, provisioning and security can be automated based on infrastructure and policy as code. Infrastructure and policies are codified, shared, managed, and executed within a workflow that is consistent across all infrastructure.

How to Define Infrastructure State

Create configurations that provide an outline for Terraform to provision your target infrastructure. For example:

terraform {
  required_providers {
    docker = {
      source = "kreuzwerker/docker"
      version = "~> 2.13.0"

provider "docker" {
    # provider-specific configuration goes here, e.g.,
    # browse provider documentation here

# Define some resources!
resource "docker_image" "nginx" {
    name         = "nginx:latest"
    keep_locally = false

resource "docker_container" "nginx" {
    image = docker_image.nginx.latest
    name  = "web-server"
    ports {
        internal = 80
        external = 8080

How to Initialize Terraform

Terraform needs to install provider-specific plugins, generate lockfiles, etc. before you can begin provisioning.

terraform init

You should only need to run this on new configurations, or other configurations checked-out from version control.

How to Lint / Check / Validate your Config

To check you have a valid configuration

terraform validate

To format your configuration files

terraform fmt

How to Provision Resources

You can generate an execution plan before committing to provisioning real resources. This command allows you to see exactly what Terraform will do when running the next command.

terraform plan

Then, to apply your configurations and provision infrastructure resources:

terraform apply

Use -auto-approve to automatically accept all user prompts (non-interactive, batch mode):

terraform apply -auto-approve

How to Execute Plans

Execution plans generated by terraform plan also act as the last working state of your infrastructure. You may wish to save the generated .tfstate file so that you may re-provision these resources reliably.

You can pass in the execution plan to terraform apply (example):

terraform apply -auto-approve ./
