Asim Aslam a5bef7af29 Add systemd-based deployment support (#2836)
* Add systemd-based deployment support

- micro init --server: Initialize server to receive deployments
  - Creates /opt/micro/{bin,data,config} directories
  - Generates systemd template unit (micro@.service)
  - Creates 'micro' system user

- micro deploy: Deploy services via SSH + systemd
  - Builds linux/amd64 binaries automatically
  - Copies via rsync/scp to server
  - Manages services via systemctl
  - Helpful error messages for common issues

- micro status --remote: Check remote service status
- micro logs --remote: Stream remote logs via journalctl
- micro stop --remote: Stop services on remote server

- Config: Added 'deploy' blocks to micro.mu for named targets

The deployment model:
- systemd is the process supervisor (battle-tested)
- SSH is the transport (standard, secure)
- No custom daemons or platforms needed

Co-authored-by: Shelley <shelley@exe.dev>

* Add deployment documentation

- docs/deployment.md: Comprehensive guide for server deployment
- README.md: Updated deployment section with full workflow

Co-authored-by: Shelley <shelley@exe.dev>

* Add deployment section to CLI documentation

Co-authored-by: Shelley <shelley@exe.dev>

* Fix systemd template escaping and rsync permission warnings

- Fix %i escaping in systemd template (was being interpreted by fmt.Sprintf)
- Handle rsync exit code 23/24 gracefully (metadata permission warnings)
- Add --omit-dir-times to rsync to avoid directory timestamp errors

Co-authored-by: Shelley <shelley@exe.dev>

* Add install script for micro CLI

Co-authored-by: Shelley <shelley@exe.dev>

* Fix non-constant format string in deploy error

### Deployment
Deploy to any Linux server with systemd:
```bash
micro build # Build Go binaries to ./bin/
micro build --os linux # Cross-compile for Linux
micro deploy --ssh user@host # Deploy via SSH
# On your server (one-time setup)
curl -fsSL https://go-micro.dev/install.sh | sh
sudo micro init --server
# From your laptop
micro deploy user@your-server
```
No Docker required. Go binaries are self-contained.
The deploy command:
1. Builds binaries for Linux
2. Copies via SSH to the server
3. Sets up systemd services
4. Verifies services are healthy
Manage deployed services:
```bash
micro status --remote user@server # Check status
micro logs --remote user@server # View logs
micro logs myservice --remote user@server -f # Follow specific service
```
No Docker required. No Kubernetes. Just systemd.
See [docs/deployment.md](docs/deployment.md) for full deployment guide.
See [cmd/micro/README.md](cmd/micro/README.md) for full CLI documentation.

## Building and Deployment
### Build Binaries
Build Go binaries for deployment:
```bash
micro build # Build for current OS
micro build --os linux # Cross-compile for Linux
micro build --os linux --arch arm64 # For ARM64
micro build --output ./dist # Custom output directory
```
### Deploy to Server
Deploy to any Linux server with systemd:
```bash
# First time: set up the server
ssh user@server
curl -fsSL https://go-micro.dev/install.sh | sh
sudo micro init --server
exit
# Deploy from your laptop
micro deploy user@server
```
The deploy command:
1. Builds binaries for linux/amd64
2. Copies via SSH to `/opt/micro/bin/`
3. Sets up systemd services (`micro@<service>`)
4. Restarts and verifies services are running
### Named Deploy Targets
Add deploy targets to `micro.mu`:
```
deploy prod
ssh deploy@prod.example.com
deploy staging
ssh deploy@staging.example.com
```
Then:
```bash
micro deploy prod # Deploy to production
micro deploy staging # Deploy to staging
```
### Managing Deployed Services
```bash
# Check status
micro status --remote user@server
# View logs
micro logs --remote user@server
micro logs myservice --remote user@server -f
# Stop a service
micro stop myservice --remote user@server
```
See [docs/deployment.md](../../docs/deployment.md) for the full deployment guide.
## Protobuf
Use protobuf for code generation with [protoc-gen-micro](https://github.com/micro/go-micro/tree/master/cmd/protoc-gen-micro)

Description: `Deploy copies binaries to a remote server and manages them with systemd.
If ./bin/ exists (from 'micro build'), copies binaries directly.
Otherwise, syncs source and builds on the remote host.
Before deploying, initialize the server:
ssh user@server 'curl -fsSL https://go-micro.dev/install.sh | sh && sudo micro init --server'
Examples:
micro build --os linux # Build Linux binaries locally
micro deploy --ssh user@host # Copy binaries and restart
Then deploy:
micro deploy user@server
micro deploy --ssh user@host # Sync source, build on remote, restart
micro deploy --ssh user@host --build # Force rebuild on remote`,
Action: Deploy,
With a micro.mu config, you can define named targets:
deploy prod
ssh user@prod.example.com
deploy staging
ssh user@staging.example.com
Then: micro deploy prod

1. Builds binaries for linux/amd64
2. Copies to /opt/micro/bin/ via rsync
3. Enables and restarts systemd services
4. Verifies services are healthy`,

# Deploying Go Micro Services
This guide covers deploying go-micro services to a Linux server using systemd.
## Overview
go-micro provides a simple deployment workflow:
1. **Develop locally** with `micro run`
2. **Build binaries** with `micro build`
3. **Deploy to server** with `micro deploy`
On the server, services are managed by systemd - the standard Linux process supervisor.
## Quick Start
### 1. Prepare Your Server
On your server (Ubuntu, Debian, or any systemd-based Linux):
```bash
# Install micro
curl -fsSL https://go-micro.dev/install.sh | sh
# Initialize for deployment
sudo micro init --server
```
This creates:
- `/opt/micro/bin/` - where service binaries live
- `/opt/micro/data/` - persistent data directory
- `/opt/micro/config/` - environment files
- systemd template for managing services
### 2. Deploy from Your Machine
```bash
# From your project directory
micro deploy user@your-server
```
That's it! The deploy command:
1. Builds your services for Linux
2. Copies binaries to the server
3. Configures and starts systemd services
4. Verifies everything is running
## Detailed Setup
### Server Requirements
- Linux with systemd (Ubuntu 16.04+, Debian 8+, CentOS 7+, etc.)
- SSH access
- Go installed (only if building on server)
### Server Initialization Options
```bash
# Basic setup (creates 'micro' user)
sudo micro init --server
# Custom installation path
sudo micro init --server --path /home/deploy/micro
# Run services as existing user
sudo micro init --server --user deploy
# Initialize remotely (from your laptop)
micro init --server --remote user@your-server
```
### What Gets Created
**Directories:**
```
/opt/micro/
├── bin/ # Service binaries
├── data/ # Persistent data (databases, files)
└── config/ # Environment files (*.env)
```
**Systemd Template** (`/etc/systemd/system/micro@.service`):
```ini
[Unit]
Description=Micro service: %i
After=network.target
[Service]
Type=simple
User=micro
WorkingDirectory=/opt/micro
ExecStart=/opt/micro/bin/%i
Restart=on-failure
RestartSec=5
EnvironmentFile=-/opt/micro/config/%i.env
[Install]
WantedBy=multi-user.target
```
The `%i` is replaced with the service name. So `micro@users.service` runs `/opt/micro/bin/users`.
## Deployment
### Basic Deploy
```bash
micro deploy user@server
```
### Deploy Specific Service
```bash
micro deploy user@server --service users
```
### Force Rebuild
```bash
micro deploy user@server --build
```
### Named Deploy Targets
Add to your `micro.mu`:
```
service users
path ./users
port 8081
service web
path ./web
port 8080
deploy prod
ssh deploy@prod.example.com
deploy staging
ssh deploy@staging.example.com
```
Then:
```bash
micro deploy prod # deploys to prod.example.com
micro deploy staging # deploys to staging.example.com
```
## Managing Services
### Check Status
```bash
# Local services
micro status
# Remote services
micro status --remote user@server
```
Output:
```
server.example.com
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
users ● running pid 1234
posts ● running pid 1235
web ● running pid 1236
```
### View Logs
```bash
# All services
micro logs --remote user@server
# Specific service
micro logs users --remote user@server
# Follow logs
micro logs users --remote user@server -f
```
### Stop Services
```bash
micro stop users --remote user@server
```
### Direct systemctl Access
You can also manage services directly on the server:
```bash
# Status
sudo systemctl status micro@users
# Restart
sudo systemctl restart micro@users
# Stop
sudo systemctl stop micro@users
# Logs
journalctl -u micro@users -f
```
## Environment Variables
Create environment files at `/opt/micro/config/<service>.env`:
```bash
# /opt/micro/config/users.env
DATABASE_URL=postgres://localhost/users
REDIS_URL=redis://localhost:6379
LOG_LEVEL=info
```
These are automatically loaded by systemd when the service starts.
## SSH Setup
### Key-Based Authentication
```bash
# Generate key (if you don't have one)
ssh-keygen -t ed25519
# Copy to server
ssh-copy-id user@server
```
### SSH Config
Add to `~/.ssh/config`:
```
Host prod
HostName prod.example.com
User deploy
IdentityFile ~/.ssh/deploy_key
Host staging
HostName staging.example.com
User deploy
IdentityFile ~/.ssh/deploy_key
```
Then deploy with:
```bash
micro deploy prod
```
## Troubleshooting
### "Cannot connect to server"
```
✗ Cannot connect to myserver
SSH connection failed. Check that:
• The server is reachable: ping myserver
• SSH is configured: ssh user@myserver
• Your key is added: ssh-add -l
```
**Fix:**
```bash
# Test SSH connection
ssh user@server
# Add SSH key
ssh-copy-id user@server
# Check SSH agent
eval $(ssh-agent)
ssh-add
```
### "Server not initialized"
```
✗ Server not initialized
micro is not set up on myserver.
```
**Fix:**
```bash
ssh user@server 'sudo micro init --server'
```
### "Service failed to start"
Check the logs:
```bash
micro logs myservice --remote user@server
# Or on the server:
journalctl -u micro@myservice -n 50
```
Common causes:
- Missing environment variables
- Port already in use
- Database not reachable
- Binary permissions issue
### "Permission denied"
Ensure your user can write to `/opt/micro/bin/`:
```bash
# On server
sudo chown -R deploy:deploy /opt/micro
# Or add user to micro group
sudo usermod -aG micro deploy
```
## Security Best Practices
1. **Use a dedicated deploy user** - Don't deploy as root
2. **Use SSH keys** - Disable password authentication
3. **Restrict sudo** - Only allow necessary commands
4. **Firewall** - Only expose needed ports
5. **Secrets** - Use environment files with restricted permissions (0600)
### Minimal sudo access
Add to `/etc/sudoers.d/micro`:
```
deploy ALL=(ALL) NOPASSWD: /bin/systemctl daemon-reload
deploy ALL=(ALL) NOPASSWD: /bin/systemctl enable micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl restart micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl stop micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl status micro@*
```
## Next Steps
- [micro run](./micro-run.md) - Local development
- [micro.mu configuration](./config.md) - Configuration file format
- [Health checks](./health.md) - Service health endpoints

# Introducing micro deploy
*January 27, 2026 • By the Go Micro Team*
We're excited to announce **micro deploy** in Go Micro v5.13.0 — a simple way to deploy your services to any Linux server.
## The Problem
Go Micro has always been great for building microservices:
```bash
micro new myservice
cd myservice
micro run
```
But getting those services to production? That was on you. You'd need to figure out Docker, Kubernetes, or write your own deployment scripts.
We tried to solve this with Micro v3 — a full platform-as-a-service. But it was too much. Too complex. Nobody wanted another platform to manage.
## The Solution
The new approach is simple: **systemd + SSH**.
Every Linux server has systemd. It's battle-tested, it manages processes, it restarts them when they crash, it handles logging. Why reinvent it?
### One-Time Server Setup
```bash
ssh user@server
curl -fsSL https://go-micro.dev/install.sh | sh
sudo micro init --server
```
This creates:
- `/opt/micro/bin/` — where your binaries live
- `/opt/micro/config/` — environment files
- A systemd template for managing services
### Deploy
```bash
micro deploy user@server
```
That's it. The command:
1. Builds your services for Linux
2. Copies binaries via SSH
3. Configures systemd services
4. Verifies everything is running
### Manage
```bash
micro status --remote user@server
micro logs --remote user@server
micro logs myservice --remote user@server -f
```
## Named Deploy Targets
Add deploy targets to your `micro.mu`:
```
service users
path ./users
port 8081
service web
path ./web
port 8080
deploy prod
ssh deploy@prod.example.com
deploy staging
ssh deploy@staging.example.com
```
Then:
```bash
micro deploy prod
micro deploy staging
```
## Philosophy
- **systemd is the standard** — don't fight it, use it
- **SSH is the transport** — no custom agents or protocols
- **Errors guide you** — every failure tells you how to fix it
- **No platform** — just your server, your services
## What's Next?
This is just the beginning. We're thinking about:
- **Secrets management** — integrating with vault/sops
- **Multi-server deploys** — deploy to a fleet
- **Metrics** — Prometheus endpoints out of the box
- **Rolling updates** — zero-downtime deployments
## Try It
```bash
go install go-micro.dev/v5/cmd/micro@v5.13.0
micro new myapp
cd myapp
micro run
# When you're ready to deploy:
micro deploy user@your-server
```
See the [deployment guide](/docs/deployment.html) for full documentation.

# Deploying Go Micro Services
This guide covers deploying go-micro services to a Linux server using systemd.
## Overview
go-micro provides a simple deployment workflow:
1. **Develop locally** with `micro run`
2. **Build binaries** with `micro build`
3. **Deploy to server** with `micro deploy`
On the server, services are managed by systemd - the standard Linux process supervisor.
## Quick Start
### 1. Prepare Your Server
On your server (Ubuntu, Debian, or any systemd-based Linux):
```bash
# Install micro
curl -fsSL https://go-micro.dev/install.sh | sh
# Initialize for deployment
sudo micro init --server
```
This creates:
- `/opt/micro/bin/` - where service binaries live
- `/opt/micro/data/` - persistent data directory
- `/opt/micro/config/` - environment files
- systemd template for managing services
### 2. Deploy from Your Machine
```bash
# From your project directory
micro deploy user@your-server
```
That's it! The deploy command:
1. Builds your services for Linux
2. Copies binaries to the server
3. Configures and starts systemd services
4. Verifies everything is running
## Detailed Setup
### Server Requirements
- Linux with systemd (Ubuntu 16.04+, Debian 8+, CentOS 7+, etc.)
- SSH access
- Go installed (only if building on server)
### Server Initialization Options
```bash
# Basic setup (creates 'micro' user)
sudo micro init --server
# Custom installation path
sudo micro init --server --path /home/deploy/micro
# Run services as existing user
sudo micro init --server --user deploy
# Initialize remotely (from your laptop)
micro init --server --remote user@your-server
```
### What Gets Created
**Directories:**
```
/opt/micro/
├── bin/ # Service binaries
├── data/ # Persistent data (databases, files)
└── config/ # Environment files (*.env)
```
**Systemd Template** (`/etc/systemd/system/micro@.service`):
```ini
[Unit]
Description=Micro service: %i
After=network.target
[Service]
Type=simple
User=micro
WorkingDirectory=/opt/micro
ExecStart=/opt/micro/bin/%i
Restart=on-failure
RestartSec=5
EnvironmentFile=-/opt/micro/config/%i.env
[Install]
WantedBy=multi-user.target
```
The `%i` is replaced with the service name. So `micro@users.service` runs `/opt/micro/bin/users`.
## Deployment
### Basic Deploy
```bash
micro deploy user@server
```
### Deploy Specific Service
```bash
micro deploy user@server --service users
```
### Force Rebuild
```bash
micro deploy user@server --build
```
### Named Deploy Targets
Add to your `micro.mu`:
```
service users
path ./users
port 8081
service web
path ./web
port 8080
deploy prod
ssh deploy@prod.example.com
deploy staging
ssh deploy@staging.example.com
```
Then:
```bash
micro deploy prod # deploys to prod.example.com
micro deploy staging # deploys to staging.example.com
```
## Managing Services
### Check Status
```bash
# Local services
micro status
# Remote services
micro status --remote user@server
```
Output:
```
server.example.com
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
users ● running pid 1234
posts ● running pid 1235
web ● running pid 1236
```
### View Logs
```bash
# All services
micro logs --remote user@server
# Specific service
micro logs users --remote user@server
# Follow logs
micro logs users --remote user@server -f
```
### Stop Services
```bash
micro stop users --remote user@server
```
### Direct systemctl Access
You can also manage services directly on the server:
```bash
# Status
sudo systemctl status micro@users
# Restart
sudo systemctl restart micro@users
# Stop
sudo systemctl stop micro@users
# Logs
journalctl -u micro@users -f
```
## Environment Variables
Create environment files at `/opt/micro/config/<service>.env`:
```bash
# /opt/micro/config/users.env
DATABASE_URL=postgres://localhost/users
REDIS_URL=redis://localhost:6379
LOG_LEVEL=info
```
These are automatically loaded by systemd when the service starts.
## SSH Setup
### Key-Based Authentication
```bash
# Generate key (if you don't have one)
ssh-keygen -t ed25519
# Copy to server
ssh-copy-id user@server
```
### SSH Config
Add to `~/.ssh/config`:
```
Host prod
HostName prod.example.com
User deploy
IdentityFile ~/.ssh/deploy_key
Host staging
HostName staging.example.com
User deploy
IdentityFile ~/.ssh/deploy_key
```
Then deploy with:
```bash
micro deploy prod
```
## Troubleshooting
### "Cannot connect to server"
```
✗ Cannot connect to myserver
SSH connection failed. Check that:
• The server is reachable: ping myserver
• SSH is configured: ssh user@myserver
• Your key is added: ssh-add -l
```
**Fix:**
```bash
# Test SSH connection
ssh user@server
# Add SSH key
ssh-copy-id user@server
# Check SSH agent
eval $(ssh-agent)
ssh-add
```
### "Server not initialized"
```
✗ Server not initialized
micro is not set up on myserver.
```
**Fix:**
```bash
ssh user@server 'sudo micro init --server'
```
### "Service failed to start"
Check the logs:
```bash
micro logs myservice --remote user@server
# Or on the server:
journalctl -u micro@myservice -n 50
```
Common causes:
- Missing environment variables
- Port already in use
- Database not reachable
- Binary permissions issue
### "Permission denied"
Ensure your user can write to `/opt/micro/bin/`:
```bash
# On server
sudo chown -R deploy:deploy /opt/micro
# Or add user to micro group
sudo usermod -aG micro deploy
```
## Security Best Practices
1. **Use a dedicated deploy user** - Don't deploy as root
2. **Use SSH keys** - Disable password authentication
3. **Restrict sudo** - Only allow necessary commands
4. **Firewall** - Only expose needed ports
5. **Secrets** - Use environment files with restricted permissions (0600)
### Minimal sudo access
Add to `/etc/sudoers.d/micro`:
```
deploy ALL=(ALL) NOPASSWD: /bin/systemctl daemon-reload
deploy ALL=(ALL) NOPASSWD: /bin/systemctl enable micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl restart micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl stop micro@*
deploy ALL=(ALL) NOPASSWD: /bin/systemctl status micro@*
```
## Next Steps
- [micro run](./micro-run.md) - Local development
- [micro.mu configuration](./config.md) - Configuration file format
- [Health checks](./health.md) - Service health endpoints
