## Why "Solarboat"?
Inspired by the Ancient Egyptian solar boats that carried Pharaohs through their celestial journey, this CLI tool is your vessel through the complexities of infrastructure management. Let Solarboat handle the operational journey, so you can focus on writing code.

## 🛠️ Usage
### Common Commands
```bash
# Scan for changed Terraform modules
solarboat scan
# Scan a specific directory
solarboat scan --path ./terraform-modules
# Scan with custom default branch
solarboat scan --default-branch develop
# Plan Terraform changes
solarboat plan
# Plan in parallel
solarboat plan --parallel 4
# Save plans to directory
solarboat plan --output-dir ./terraform-plans
# Ignore workspaces
solarboat plan --ignore-workspaces dev,staging
# Plan all stateful modules
solarboat plan --all
# Apply changes (dry-run by default)
solarboat apply
# Apply for real
solarboat apply --dry-run=false
# Ignore workspaces
solarboat apply --ignore-workspaces prod,staging
# Apply all stateful modules
solarboat apply --all
# Real-time output
solarboat plan --watch
# Combine flags
solarboat plan --all --watch --var-files vars.tfvars
```
### Command Overview
- **scan**: Analyze repo for changed modules and dependencies. No changes made.
- **plan**: Generate Terraform plans for changed modules. Supports parallelism, workspace filtering, and output directory.
- **apply**: Apply changes to infrastructure. Dry-run by default, supports real-time output and workspace filtering.
#### Default Branch
- Compares changes against `main` by default. Use `--default-branch` to override.
#### Parallel Processing
- Use `--parallel N` (max 4) to process modules in parallel. Ex: `solarboat plan --parallel 3`
- In `--watch` mode, parallelism is forced to 1 for clean output.
#### Watch Mode
- `--watch` streams real-time Terraform output. Great for debugging and monitoring.
- Without `--watch`, operations run silently for CI/CD cleanliness.
#### Timeout Handling
- Initialization: 5 min
- Planning: 10 min
- Apply: 30 min

## ⚙️ Configuration
Solarboat supports flexible configuration via JSON files.
**Quick Start:**
1. Create `solarboat.json` in your project root:
```json
{
"global": {
"ignore_workspaces": ["dev", "test"],
"var_files": ["global.tfvars"],
"workspace_var_files": {
"prod": ["prod.tfvars"]
}
},
"modules": {
"infrastructure/networking": {
"ignore_workspaces": ["test"],
"var_files": ["networking.tfvars"],
"workspace_var_files": {
"prod": ["networking-prod.tfvars"]
}
}
}
}
```
2. Run Solarboat as usual. It auto-loads your config.
**Environment-Specific Config:**
```bash
SOLARBOAT_ENV=prod solarboat plan
```
Solarboat will look for `solarboat.prod.json` if set.
**Config Precedence:**
1. CLI arguments (highest)
2. Module config
3. Global config
4. Defaults (lowest)
**More:** See [CONFIGURATION.md](./CONFIGURATION.md) for full docs.

## 🧑💻 GitHub Actions Integration
Solarboat comes with a GitHub Action for CI/CD automation.
### **GitHub Token Requirements**
The GitHub token is **optional** and only needed for:
- 📝 **PR Comments**: Automatic plan summaries posted to pull requests
- 📊 **Enhanced Integration**: Access to GitHub API features
**Most common scenarios:**
- ✅ **Basic Usage**: No token required for core functionality (scan, plan, apply)
- ✅ **PR Comments**: Use `${{ secrets.GITHUB_TOKEN }}` (automatically provided by GitHub)
- ⚠️ **Custom Permissions**: Use custom token only if default permissions aren't sufficient
### **Basic Workflow (Minimal Setup):**
```yaml
name: Infrastructure CI/CD
on: [push, pull_request]
jobs:
terraform:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 0
- name: Scan for Changes
uses: devqik/solarboat@v0.8.6
with:
command: scan
- name: Plan Infrastructure
if: github.event_name == 'pull_request'
uses: devqik/solarboat@v0.8.6
with:
command: plan
output-dir: terraform-plans
# Add token for PR comments
github_token: ${{ secrets.GITHUB_TOKEN }}
- name: Apply Changes
if: github.ref == 'refs/heads/main'
uses: devqik/solarboat@v0.8.6
with:
command: apply
apply-dryrun: false
```
### **Production Workflow (Full Features):**
```yaml
name: Infrastructure Automation
on:
push:
branches: [main]
pull_request:
branches: [main]
permissions:
contents: read
pull-requests: write # For PR comments
jobs:
infrastructure:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
with:
fetch-depth: 0
- name: Plan Infrastructure Changes
if: github.event_name == 'pull_request'
uses: devqik/solarboat@v0.8.6
with:
command: plan
config: ./infrastructure/solarboat.json
terraform-version: "1.8.0"
solarboat-version: "v0.8.6"
parallel: 3
ignore-workspaces: dev,test
output-dir: terraform-plans
github_token: ${{ secrets.GITHUB_TOKEN }}
- name: Apply Infrastructure Changes
if: github.ref == 'refs/heads/main'
uses: devqik/solarboat@v0.8.6
with:
command: apply
apply-dryrun: false
config: ./infrastructure/solarboat.json
terraform-version: "1.8.0"
parallel: 2
continue-on-error: false
```
### **Pipeline-Supplied Commits (New Feature)**
Solarboat now supports intelligent change detection with pipeline-supplied commit information for more reliable CI/CD workflows.
#### **Automatic Detection (Recommended)**
The GitHub Action automatically detects the appropriate commits based on the event:
- **Pull Requests**: Uses `base.sha` and `head.sha` from the PR
- **Main Branch Pushes**: Uses `before` and `after` commit hashes
- **Local Mode**: Falls back to checking recent commits (configurable)
#### **Manual Commit Specification**
For advanced use cases, you can manually specify commit ranges:
```yaml
- name: Custom Commit Comparison
uses: devqik/solarboat@v0.8.6
with:
command: plan
base-commit: abc1234
head-commit: def5678
base-branch: main
head-branch: feature/new-module
```
#### **Local Development Mode**
When no commit information is provided, Solarboat runs in local mode:
```yaml
- name: Local Development Mode
uses: devqik/solarboat@v0.8.6
with:
command: plan
recent-commits: 5 # Check last 5 commits for changes
```

echo "🚨 Infrastructure apply failed!"
echo "Check logs and retry manually"
```
### **Permissions**

```yaml
permissions:
contents: read # Read repository contents
pull-requests: write # Comment on pull requests
```
**Note**: `${{ secrets.GITHUB_TOKEN }}` is automatically provided by GitHub with repository access. Custom tokens are only needed for cross-repository access or enhanced permissions.
