A Terraform provider for Dokploy

Plugin-framework provider covering projects, environments, applications,
Compose stacks, managed databases, domains, mounts, ports, redirects,
basic auth, registries, SSH keys, certificates and backup destinations,
over Dokploy's tRPC-over-REST API.

The shim package exposes the provider to other Go modules, which is how
pulumi-dokploy bridges it.

# Terraform Style Guide - Security
When generating code, apply security hardening:
- Enable encryption at rest by default
- Configure private networking where applicable
- Apply principle of least privilege for security groups
- Enable logging and monitoring
- Never hardcode credentials or secrets
- Mark sensitive outputs with `sensitive = true`
- Use `ephemeral` resources and write-only attributes
for sensitive data when possible
## Example: Secure S3 Bucket
```hcl
resource "aws_s3_bucket" "data" {
bucket = "${var.project}-${var.environment}-data"
tags = local.common_tags
}
resource "aws_s3_bucket_versioning" "data" {
bucket = aws_s3_bucket.data.id
versioning_configuration {
status = "Enabled"
}
}
resource "aws_s3_bucket_server_side_encryption_configuration" "data" {
bucket = aws_s3_bucket.data.id
rule {
apply_server_side_encryption_by_default {
sse_algorithm = "aws:kms"
kms_master_key_id = aws_kms_key.s3.arn
}
}
}
resource "aws_s3_bucket_public_access_block" "data" {
bucket = aws_s3_bucket.data.id
block_public_acls = true
block_public_policy = true
ignore_public_acls = true
restrict_public_buckets = true
}
```
## Ephemeral resources
Ephemeral resources prevent sensitive data being stored in state.
For more information on ephemeral resources, see the
[Terraform documentation](https://developer.hashicorp.com/terraform/language/block/ephemeral).
Before you generate code for an ephemeral resource, check that the Terraform
version is greater than or equal to 1.11.0.
Then, follow this priority order for managing sensitive attributes:
1. **First priority: Native secrets manager integration**
If a resource has the ability to automatically manage a sensitive attribute by
storing it in a secrets manager (e.g., AWS Secrets Manager, Azure Key Vault),
use that configuration. This is the preferred approach.
```hcl
# Bad
resource "aws_rds_cluster" "example" {
cluster_identifier = "example"
database_name = "test"
master_username = "test"
master_password = var.db_master_password
}
# Good, managed by AWS Secrets Manager by default
resource "aws_rds_cluster" "test" {
cluster_identifier = "example"
database_name = "test"
manage_master_user_password = true
master_username = "test"
}
```
2. **Second priority: Write-only attributes with ephemeral resources**
If a resource has a write-only attribute but no native secrets manager integration,
use an `ephemeral` resource for the sensitive data and pass that to the write-only
attribute. Default the write-only version to 1.
```hcl
# Bad
resource "random_password" "password" {
length = 16
special = true
override_special = "!#$%&*()-_=+[]{}<>:?"
}
resource "vault_kv_secret_v2" "example" {
mount = vault_mount.kvv2.path
name = "secret"
data_json = jsonencode(
{
password = "${random_password.password.result}",
}
)
}
# Good
ephemeral "random_password" "password" {
length = 16
special = true
override_special = "!#$%&*()-_=+[]{}<>:?"
}
resource "vault_kv_secret_v2" "example" {
mount = vault_mount.kvv2.path
name = "secret"
data_json_wo = jsonencode(
{
password = "${ephemeral.random_password.password.result}",
}
)
data_json_wo_version = 1
}
```
If you need to retrieve a secret from a secrets manager to pass
to a resource, use the `ephemeral` version of the resource to
retrieve the secret and pass it to another resource.
```hcl
# Good
ephemeral "vault_kv_secret_v2" "db_secret" {
mount = vault_mount.kvv2.path
mount_id = vault_mount.kvv2.id
name = vault_kv_secret_v2.db_root.name
}
resource "vault_database_secret_backend_connection" "postgres" {
backend = vault_mount.db.path
name = "postrgres-db"
allowed_roles = ["*"]
postgresql {
connection_url = "postgresql://{{username}}:{{password}}@localhost:5432/postgres"
password_authentication = ""
username = "postgres"
password_wo = tostring(ephemeral.vault_kv_secret_v2.db_secret.data.password)
password_wo_version = 1
}
}
```
3. **Last resort: Regular resources**
Only use a regular resource that has sensitive data written to state if neither of the above
options are available, resource does not offer a write-only attribute or ephemeral resource
alternative, or the Terraform version is less than 1.11.0.

# Terraform Style Guide
Generate and maintain Terraform code following HashiCorp's official style conventions and best practices.
**Reference:** [HashiCorp Terraform Style Guide](https://developer.hashicorp.com/terraform/language/style)
## Code Generation Strategy
When generating Terraform code:
1. Start with provider configuration and version constraints
2. Create data sources before dependent resources
3. Build resources in dependency order
4. Add outputs for key resource attributes
5. Use variables for all configurable values
## File Organization
| File | Purpose |
|------|---------|
| `terraform.tf` | Terraform and provider version requirements |
| `providers.tf` | Provider configurations |
| `main.tf` | Primary resources and data sources |
| `variables.tf` | Input variable declarations (alphabetical) |
| `outputs.tf` | Output value declarations (alphabetical) |
| `locals.tf` | Local value declarations |
### Example Structure
```hcl
# terraform.tf
terraform {
required_version = ">= 1.14"
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 6.0"
}
}
}
# variables.tf
variable "environment" {
description = "Target deployment environment"
type = string
validation {
condition = contains(["dev", "staging", "prod"], var.environment)
error_message = "Environment must be dev, staging, or prod."
}
}
# locals.tf
locals {
common_tags = {
Environment = var.environment
ManagedBy = "Terraform"
}
}
# main.tf
resource "aws_vpc" "main" {
cidr_block = var.vpc_cidr
enable_dns_hostnames = true
tags = merge(local.common_tags, {
Name = "${var.project_name}-${var.environment}-vpc"
})
}
# outputs.tf
output "vpc_id" {
description = "ID of the created VPC"
value = aws_vpc.main.id
}
```
## Code Formatting
### Indentation and Alignment
- Use **two spaces** per nesting level (no tabs)
- Align equals signs for consecutive arguments
```hcl
resource "aws_instance" "web" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
subnet_id = "subnet-12345678"
tags = {
Name = "web-server"
Environment = "production"
}
}
```
### Block Organization
Arguments precede blocks, with meta-arguments first:
```hcl
resource "aws_instance" "example" {
# Meta-arguments
count = 3
# Arguments
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
# Blocks
root_block_device {
volume_size = 20
}
# Lifecycle last
lifecycle {
create_before_destroy = true
}
}
```
## Naming Conventions
- Use **lowercase with underscores** for all names
- Use **descriptive nouns** excluding the resource type
- Be specific and meaningful
- Resource names must be singular, not plural
- Default to `main` for resources where a specific descriptive name is redundant or unavailable, provided only one instance exists
```hcl
# Bad
resource "aws_instance" "webAPI-aws-instance" {}
resource "aws_instance" "web_apis" {}
variable "name" {}
# Good
resource "aws_instance" "web_api" {}
resource "aws_vpc" "main" {}
variable "application_name" {}
```
## Variables
Every variable must include `type` and `description`:
```hcl
variable "instance_type" {
description = "EC2 instance type for the web server"
type = string
default = "t2.micro"
validation {
condition = contains(["t2.micro", "t2.small", "t2.medium"], var.instance_type)
error_message = "Instance type must be t2.micro, t2.small, or t2.medium."
}
}
variable "database_password" {
description = "Password for the database admin user"
type = string
sensitive = true
}
```
## Outputs
Every output must include `description`:
```hcl
output "instance_id" {
description = "ID of the EC2 instance"
value = aws_instance.web.id
}
output "database_password" {
description = "Database administrator password"
value = aws_db_instance.main.password
sensitive = true
}
```
## Dynamic Resource Creation
### Prefer for_each over count
```hcl
# Bad - count for multiple resources
resource "aws_instance" "web" {
count = var.instance_count
tags = { Name = "web-${count.index}" }
}
# Good - for_each with named instances
variable "instance_names" {
type = set(string)
default = ["web-1", "web-2", "web-3"]
}
resource "aws_instance" "web" {
for_each = var.instance_names
tags = { Name = each.key }
}
```
### count for Conditional Creation
```hcl
resource "aws_cloudwatch_metric_alarm" "cpu" {
count = var.enable_monitoring ? 1 : 0
alarm_name = "high-cpu-usage"
threshold = 80
}
```
## Security Best Practices
Refer to SECURITY.md. It includes guidance on encrypting resources,
preventing sensitive data in state, and secure configurations.
## Version Pinning
```hcl
terraform {
required_version = ">= 1.14"
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 6.0"
}
}
}
```
Use the latest major version of each provider and the latest minor version of
Terraform, unless otherwise constrained by a dependency lock file or by other
modules used by the configuration.
**Version constraint operators:**
- `= 1.0.0` - Exact version
- `>= 1.0.0` - Greater than or equal
- `~> 1.0` - Allow rightmost component to increment
- `>= 1.0, < 2.0` - Version range
## Provider Configuration
```hcl
provider "aws" {
region = "us-west-2"
default_tags {
tags = {
ManagedBy = "Terraform"
Project = var.project_name
}
}
}
# Aliased provider for multi-region
provider "aws" {
alias = "east"
region = "us-east-1"
}
```
## Version Control
**Never commit:**
- `terraform.tfstate`, `terraform.tfstate.backup`
- `.terraform/` directory
- `*.tfplan`
- `.tfvars` files with sensitive data
**Always commit:**
- All `.tf` configuration files
- `.terraform.lock.hcl` (dependency lock file)
## Validation Tools
Run before committing:
```bash
terraform fmt -recursive
terraform validate
```
Additional tools:
- `tflint` - Linting and best practices
- `checkov` / `tfsec` - Security scanning
## Code Review Checklist
