# Git Branching Strategy for Infrastructure Management
|
||||
|
||||
## Branch Structure
|
||||
|
||||
### Main Branches
|
||||
|
||||
#### `main`
|
||||
- **Purpose**: Production-ready configurations
|
||||
- **Protection**: Protected branch with required reviews
|
||||
- **Deployment**: Automatically deployed to production machines
|
||||
- **Stability**: Should always be stable and tested
|
||||
|
||||
#### `develop`
|
||||
- **Purpose**: Integration branch for new features
|
||||
- **Testing**: Continuous integration testing
|
||||
- **Merging**: Features merge here first
|
||||
- **Deployment**: Deployed to staging/test environments
|
||||
|
||||
### Supporting Branches
|
||||
|
||||
#### Feature Branches: `feature/<description>`
|
||||
- **Purpose**: Development of new features or modules
|
||||
- **Naming**: `feature/add-cosmic-desktop`, `feature/sleeper-service-config`
|
||||
- **Lifetime**: Temporary, deleted after merge
|
||||
- **Source**: Branch from `develop`
|
||||
- **Merge**: Merge back to `develop`
|
||||
|
||||
#### Machine Branches: `machine/<machine-name>`
|
||||
- **Purpose**: Machine-specific configuration changes
|
||||
- **Naming**: `machine/congenital-optimist`, `machine/sleeper-service`
|
||||
- **Use Case**: Testing machine-specific changes
|
||||
- **Merge**: Merge to `develop` after testing
|
||||
|
||||
#### Hotfix Branches: `hotfix/<issue>`
|
||||
- **Purpose**: Critical fixes for production
|
||||
- **Naming**: `hotfix/security-patch`, `hotfix/boot-failure`
|
||||
- **Source**: Branch from `main`
|
||||
- **Merge**: Merge to both `main` and `develop`
|
||||
|
||||
#### Module Branches: `module/<module-name>`
|
||||
- **Purpose**: Development of specific modules
|
||||
- **Naming**: `module/virtualization`, `module/desktop-gnome`
|
||||
- **Scope**: Single module focus
|
||||
- **Testing**: Module-specific testing
|
||||
|
||||
### Tagging Strategy
|
||||
|
||||
#### Version Tags: `v<major>.<minor>.<patch>`
|
||||
- **Purpose**: Mark stable releases
|
||||
- **Format**: `v1.0.0`, `v1.2.1`
|
||||
- **Trigger**: Major configuration milestones
|
||||
- **Deployment**: Tag triggers deployment workflows
|
||||
|
||||
#### Machine Tags: `<machine>-v<version>`
|
||||
- **Purpose**: Machine-specific deployments
|
||||
- **Format**: `congenital-optimist-v1.0.0`
|
||||
- **Use Case**: Track per-machine configurations
|
||||
- **Rollback**: Enable machine-specific rollbacks
|
||||
|
||||
#### Phase Tags: `phase-<number>-complete`
|
||||
- **Purpose**: Mark migration phase completion
|
||||
- **Format**: `phase-1-complete`, `phase-2-complete`
|
||||
- **Documentation**: Link to plan.md milestones
|
||||
|
||||

|
||||
|
||||
## Branch Protection Rules
|
||||
|
||||
### Main Branch Protection
|
||||
- **Required Reviews**: 1 reviewer minimum
|
||||
- **Status Checks**: All CI checks must pass
|
||||
- **Up-to-date**: Branch must be up to date before merging
|
||||
- **Admin Override**: Allow admin override for hotfixes
|
||||
- **Force Push**: Disabled
|
||||
- **Deletion**: Disabled
|
||||
|
||||
### Develop Branch Protection
|
||||
- **Required Reviews**: 1 reviewer (can be self-review)
|
||||
- **Status Checks**: All CI checks must pass
|
||||
- **Auto-merge**: Allow auto-merge after checks
|
||||
- **Force Push**: Disabled for others
|
||||
|
||||
## Merge Strategies
|
||||
|
||||
### Feature to Develop
|
||||
- **Strategy**: Squash and merge
|
||||
- **Reason**: Clean history, single commit per feature
|
||||
- **Title**: Use conventional commit format
|
||||
|
||||
### Develop to Main
|
||||
- **Strategy**: Merge commit
|
||||
- **Reason**: Preserve feature branch history
|
||||
- **Testing**: Full integration testing required
|
||||
|
||||
### Hotfix to Main
|
||||
- **Strategy**: Fast-forward if possible
|
||||
- **Reason**: Immediate deployment needed
|
||||
- **Testing**: Minimal but critical testing
|
||||
|
||||
## Deployment Strategy
|
||||
|
||||
### Automatic Deployment
|
||||
- **main** → Production machines (congenital-optimist, sleeper-service)
|
||||
- **develop** → Test environment (if available)
|
||||
|
||||
### Manual Deployment
|
||||
- Feature branches can be manually deployed for testing
|
||||
- Use `nixos-rebuild test` for non-persistent testing
|
||||
- Use `nixos-rebuild switch` for persistent changes
|
||||
|
||||
### Rollback Strategy
|
||||
```bash
|
||||
# Rollback to previous version
|
||||
git checkout main
|
||||
git revert <commit-hash>
|
||||
git tag rollback-v1.0.0-to-v0.9.9
|
||||
|
||||
# Or rollback to specific tag
|
||||
git checkout v1.0.0
|
||||
sudo nixos-rebuild switch --flake .#congenital-optimist
|
||||
```
|
||||
|
||||
## Branch Lifecycle
|
||||
|
||||
### Weekly Maintenance
|
||||
- **Monday**: Review open feature branches
|
||||
- **Wednesday**: Merge develop to main if stable
|
||||
- **Friday**: Clean up merged feature branches
|
||||
- **Sunday**: Update dependencies (automated)
|
||||
|
||||
### Monthly Tasks
|
||||
- Review and update branch protection rules
|
||||
- Clean up old tags and releases
|
||||
- Update documentation
|
||||
- Security audit of configurations
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Branch Naming
|
||||
- Use descriptive names: `feature/improve-zfs-performance`
|
||||
- Include issue numbers: `feature/123-add-cosmic-desktop`
|
||||
- Use lowercase with hyphens
|
||||
- Keep names under 50 characters
|
||||
|
||||
### Commit Messages
|
||||
- Use imperative mood: "add", "fix", "update"
|
||||
- Keep first line under 50 characters
|
||||
- Include body for complex changes
|
||||
- Reference issues: "Fixes #123"
|
||||
|
||||
### Testing Requirements
|
||||
- Always run `nix flake check` before committing
|
||||
- Test with `nixos-rebuild test` on relevant machines
|
||||
- Document testing performed in PR description
|
||||
- Consider impact on other machines
|
||||
|
||||
### Code Review
|
||||
- Focus on configuration correctness
|
||||
- Check for security implications
|
||||
- Verify documentation updates
|
||||
- Ensure rollback plan exists
|
||||
- Test locally when possible
|
||||
|

# CLI Tools Consolidation Summary
|
||||
|
||||
## Overview
|
||||
Successfully consolidated common CLI tools from multiple user and machine configurations into `modules/common/base.nix` to reduce duplication and improve maintainability.
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Enhanced `modules/common/base.nix`
|
||||
**Added packages:**
|
||||
- Modern CLI tools (rust-based): `eza`, `bat`, `ripgrep`, `du-dust`, `bottom`, `fd`, `fzf`, `zoxide`, `tldr`
|
||||
- Essential system tools: `curl`, `wget`, `git`, `htop`, `tree`, `file`, `unzip`, `zip`
|
||||
- Text processing: `jq`, `yq`
|
||||
- Network utilities: `nmap`
|
||||
- System diagnostics: `lsof`, `strace`, `ncdu`
|
||||
- Development basics: `github-cli`
|
||||
- Environment management: `direnv`, `nix-direnv`
|
||||
- Additional tools: `fastfetch`, `zellij`, `glances`, `systemctl-tui`, `uutils-coreutils-noprefix`
|
||||
|
||||
**Added aliases:**
|
||||
- Editor shortcuts: `vi`/`vim` → `nvim`, `h` → `tldr`
|
||||
- Modern CLI replacements: `ls` → `eza -l`, `cat` → `bat`, `grep` → `rg`, `top` → `btm`, `du` → `dust`, `find` → `fd`
|
||||
- Git shortcuts: `gs`, `ga`, `gc`, `gp`, `gpa`, `gl`
|
||||
- **Fixed `gpa` alias**: Now uses `git remote | xargs -L1 git push` for pushing to all remotes
|
||||
|
||||
### 2. Cleaned up `modules/users/common.nix`
|
||||
**Removed duplicated packages:**
|
||||
- `git`, `curl`, `wget`, `file`, `unzip`, `zip` (moved to base.nix)
|
||||
|
||||
**Removed duplicated aliases:**
|
||||
- Basic CLI tool replacements (`ls`, `grep`, `find`, `cat`) moved to base.nix
|
||||
- Basic git shortcuts moved to base.nix
|
||||
|
||||
### 3. Cleaned up `modules/users/geir.nix`
|
||||
**Removed duplicated packages:**
|
||||
- `wget`, `curl`, `htop`, `bottom`, `github-cli` (moved to base.nix)
|
||||
|
||||
### 4. Cleaned up `modules/users/sma.nix`
|
||||
**Removed duplicated packages:**
|
||||
- `htop`, `lsof`, `strace`, `curl`, `wget`, `tree`, `fd`, `ripgrep`, `fzf`, `ncdu`, `jq`, `yq`, `git`, `nmap` (moved to base.nix)
|
||||
|
||||
### 5. Cleaned up machine configurations
|
||||
**reverse-proxy configuration:**
|
||||
- Removed `curl`, `htop`, `bottom`, `git` (now in base.nix)
|
||||
|
||||
**grey-area configuration:**
|
||||
- Removed `curl`, `htop`, `wget`, `git` (now in base.nix)
|
||||
|
||||
### 6. Cleaned up `packages/default.nix`
|
||||
- Removed re-exports of `git`, `curl`, `wget` (now in base.nix)
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **Reduced Duplication**: Eliminated 20+ instances of duplicated package declarations
|
||||
2. **Better Maintainability**: Single source of truth for common CLI tools
|
||||
3. **Consistency**: All machines get the same base set of modern CLI tools
|
||||
4. **Simplified User Configs**: User-specific configs now focus on user-specific needs
|
||||
5. **Easier Updates**: Update CLI tool versions in one place instead of multiple files
|
||||
|
||||
## Package Organization in base.nix
|
||||
|
||||
```nix
|
||||
# Modern CLI tools (rust-based replacements)
|
||||
tldr, eza, bat, ripgrep, du-dust, bottom, fd, fzf, zoxide, uutils-coreutils-noprefix
|
||||
|
||||
# Environment management
|
||||
direnv, nix-direnv
|
||||
|
||||
# Essential system tools
|
||||
curl, wget, git, htop, tree, file, unzip, zip
|
||||
|
||||
# Text processing and utilities
|
||||
jq, yq
|
||||
|
||||
# Network utilities
|
||||
nmap
|
||||
|
||||
# System monitoring and diagnostics
|
||||
lsof, strace, ncdu
|
||||
|
||||
# Development basics
|
||||
github-cli
|
||||
```
|
||||
|
||||
## Verification
|
||||
- ✅ `nix flake check` passes
|
||||
- ✅ Dry-run build of congenital-optimist configuration succeeds
|
||||
- ✅ All machines import base.nix via flake configuration
|
||||
- ✅ No package conflicts or missing dependencies
|
||||
|
||||
## Next Steps
|
||||
1. Consider creating additional specialized modules (e.g., `development/cli-tools.nix`) for development-specific tools
|
||||
2. Monitor for any additional duplications as new packages are added
|
||||
3. Consider consolidating shell aliases further if patterns emerge
|
||||
|
||||
## Final Completion Notes (Latest Updates)
|
||||
|
||||
### Git Alias Consolidation Completed
|
||||
- **✅ `gpa` alias fixed**: Properly configured in `base.nix` to push to all remotes using `git remote | xargs -L1 git push`
|
||||
- **✅ Removed duplicate**: Eliminated hardcoded `git-push-all` alias from `geir.nix` that only worked with specific remotes (origin/github)
|
||||
- **✅ Better flexibility**: The generic `gpa` alias now works with any git repository configuration
|
||||
|
||||
### Final Status
|
||||
- **✅ All consolidation complete**: CLI tools, aliases, and git functionality fully consolidated
|
||||
- **✅ No remaining duplications**: Comprehensive cleanup across all configuration files
|
||||
- **✅ Validation passed**: `nix flake check` and `nixos-rebuild dry-run` both successful
|
||||
- **✅ Ready for deployment**: All changes tested and validated
|
||||
|
||||
The CLI tools consolidation project is now **100% complete** with improved git workflow capabilities.

git push origin feature/improve-desktop-config
|
||||
```
|
||||
|
||||
### 2. Pull Request Process
|
||||
1. **Create PR** from feature branch to `develop`
|
||||
2. **Automated Testing** runs via GitHub Actions:
|
||||
- Flake syntax validation
|
||||
- Build tests for all machines
|
||||
- Security audit
|
||||
- Documentation checks
|
||||
3. **Code Review** by team members
|
||||
4. **Local Testing** by reviewers (optional but recommended)
|
||||
5. **Merge** to develop after approval
|
||||
|
||||
### 3. Production Deployment
|
||||
```bash
|
||||
# Merge develop to main (after testing)
|
||||
git checkout main
|
||||
git merge develop
|
||||
|
||||
# Tag release
|
||||
git tag -a v1.1.0 -m "Release v1.1.0: Desktop improvements"
|
||||
|
||||
# Deploy to production
|
||||
sudo nixos-rebuild switch --flake .#congenital-optimist
|
||||
```
|
||||
|
||||
## 🧪 Testing Strategy
|
||||
|
||||
### Automated Testing (CI/CD)
|
||||
Our GitHub Actions pipeline automatically tests:
|
||||
|
||||
- **Syntax Validation**: `nix flake check --all-systems`
|
||||
- **Build Testing**: Full system build for each machine
|
||||
- **Security Scanning**: Check for secrets and vulnerabilities
|
||||
- **Module Validation**: Individual module testing
|
||||
- **Documentation**: Ensure docs are up to date
|
||||
|
||||
### Manual Testing Levels
|
||||
|
||||
#### Level 1: Basic Validation
|
||||
```bash
|
||||
# Quick syntax check
|
||||
nix flake check
|
||||
|
||||
# Build without applying
|
||||
nix build .#nixosConfigurations.congenital-optimist.config.system.build.toplevel
|
||||
```
|
||||
|
||||
#### Level 2: Safe Testing
|
||||
```bash
|
||||
# Test configuration (temporary, reverts on reboot)
|
||||
sudo nixos-rebuild test --flake .#congenital-optimist
|
||||
|
||||
# Verify services
|
||||
systemctl status incus libvirtd podman.socket
|
||||
```
|
||||
|
||||
#### Level 3: Persistent Testing
|
||||
```bash
|
||||
# Apply configuration permanently
|
||||
sudo nixos-rebuild switch --flake .#congenital-optimist
|
||||
|
||||
# Create rollback point
|
||||
sudo nixos-rebuild test --flake .#congenital-optimist --rollback
|
||||
```
|
||||
|
||||
## 🏗️ Configuration Architecture
|
||||
|
||||
### Module Organization
|
||||
```
|
||||
modules/
|
||||
├── common/ # Shared base configuration
|
||||
├── desktop/ # Desktop environment modules
|
||||
├── development/ # Development tools and editors
|
||||
├── hardware/ # Hardware-specific configurations
|
||||
├── services/ # Service configurations
|
||||
├── system/ # Core system modules
|
||||
├── users/ # User configurations
|
||||
└── virtualization/ # Container and VM setup
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
#### Module Design
|
||||
- **Single Responsibility**: Each module handles one aspect
|
||||
- **Configurable**: Use options for customization
|
||||
- **Documented**: Include comments and documentation
|
||||
- **Testable**: Design for easy testing
|
||||
|
||||
#### Configuration Changes
|
||||
- **Small Commits**: Make focused, atomic changes
|
||||
- **Test First**: Always test before committing
|
||||
- **Document Impact**: Explain what changes and why
|
||||
- **Consider Rollback**: Ensure changes can be reverted
|
||||
|
||||
## 🔐 Security Considerations
|
||||
|
||||
### Configuration Security
|
||||
- **No Secrets in Git**: Never commit passwords, keys, or certificates
|
||||
- **Proper Permissions**: Set correct file permissions in configuration
|
||||
- **Firewall Rules**: Review network access changes
|
||||
- **User Privileges**: Validate user group memberships
|
||||
|
||||
### Development Security
|
||||
- **Branch Protection**: Main branch requires reviews
|
||||
- **Signed Commits**: Consider GPG signing for production
|
||||
- **Access Control**: Limit who can deploy to production
|
||||
- **Audit Trail**: All changes tracked in git history
|
||||
|
||||
## 🚨 Emergency Procedures
|
||||
|
||||
### Rollback Procedures
|
||||
|
||||
#### Git-based Rollback
|
||||
```bash
|
||||
# Find last known good commit
|
||||
git log --oneline
|
||||
|
||||
# Rollback to specific commit
|
||||
git checkout <commit-hash>
|
||||
sudo nixos-rebuild switch --flake .#congenital-optimist
|
||||
|
||||
# Or revert specific changes
|
||||
git revert <bad-commit-hash>
|
||||
```
|
||||
|
||||
#### NixOS Generation Rollback
|
||||
```bash
|
||||
# List available generations
|
||||
sudo nixos-rebuild list-generations
|
||||
|
||||
# Rollback to previous generation
|
||||
sudo nixos-rebuild switch --rollback
|
||||
|
||||
# Or switch to specific generation
|
||||
sudo /nix/var/nix/profiles/system-<generation>-link/bin/switch-to-configuration switch
|
||||
```
|
||||
|
||||
#### ZFS Snapshot Rollback
|
||||
```bash
|
||||
# List snapshots
|
||||
zfs list -t snapshot
|
||||
|
||||
# Rollback to snapshot (destructive!)
|
||||
zfs rollback zpool/root@pre-update-snapshot
|
||||
```
|
||||
|
||||
### Recovery Boot
|
||||
If system fails to boot:
|
||||
1. Boot from NixOS installation media
|
||||
2. Import ZFS pools if needed
|
||||
3. Chroot into system
|
||||
4. Rollback to working configuration
|
||||
5. Rebuild and reboot
|
||||
|
||||
