# Service Orchestration: slcompose
|
||||
|
||||
## Overview
|
||||
|
||||
**slcompose** is the central service orchestrator for SilverLinux. It manages all Docker services in `/srv/docker/` with automated secret injection from Infisical.
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
System Boot
|
||||
↓
|
||||
systemd: slcompose.service
|
||||
↓
|
||||
/usr/local/bin/slcompose boot
|
||||
↓
|
||||
For each service in /srv/docker/:
|
||||
├─ Load Infisical Token from /etc/infisical/token
|
||||
├─ Discover docker-compose.yml
|
||||
├─ Extract service name from directory (e.g., gitea)
|
||||
├─ Inject secrets: infisical run --path=/gitea
|
||||
└─ Execute: docker compose up -d
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
Copy `slcompose.sh` to `/usr/local/bin/slcompose` and make executable:
|
||||
|
||||
```bash
|
||||
sudo cp docs/slcompose.sh /usr/local/bin/slcompose
|
||||
sudo chmod +x /usr/local/bin/slcompose
|
||||
```
|
||||
|
||||
Copy systemd service file:
|
||||
|
||||
```bash
|
||||
sudo cp docs/slcompose.service /etc/systemd/system/slcompose.service
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable slcompose.service
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### List Services
|
||||
|
||||
```bash
|
||||
slcompose list
|
||||
```
|
||||
|
||||
Output:
|
||||
```
|
||||
Available services:
|
||||
====================
|
||||
- gitea
|
||||
- portainer
|
||||
- postgres
|
||||
- mssql
|
||||
- openproject
|
||||
- jitsi
|
||||
- nginx-proxy-manager
|
||||
- postgres
|
||||
- baget
|
||||
- dbgate
|
||||
```
|
||||
|
||||
### Boot All Services
|
||||
|
||||
```bash
|
||||
slcompose boot
|
||||
```
|
||||
|
||||
This is automatically called by systemd on server startup.
|
||||
|
||||
### Start a Service
|
||||
|
||||
```bash
|
||||
slcompose up gitea
|
||||
```
|
||||
|
||||
- Loads Infisical token
|
||||
- Injects secrets from Infisical path: `/gitea`
|
||||
- Runs: `docker compose up -d` in `/srv/docker/gitea`
|
||||
|
||||
### Stop a Service
|
||||
|
||||
```bash
|
||||
slcompose down gitea
|
||||
```
|
||||
|
||||
### Restart a Service
|
||||
|
||||
```bash
|
||||
slcompose restart gitea
|
||||
```
|
||||
|
||||
### View Logs
|
||||
|
||||
Stream live logs (Ctrl+C to exit):
|
||||
```bash
|
||||
slcompose logs gitea
|
||||
```
|
||||
|
||||
View last N lines (default 200):
|
||||
```bash
|
||||
slcompose logs-tail gitea
|
||||
slcompose logs-tail gitea 500
|
||||
```
|
||||
|
||||
### View Injected Environment Variables
|
||||
|
||||
View all environment variables injected into a specific service from Infisical:
|
||||
|
||||
```bash
|
||||
slcompose env gitea
|
||||
```
|
||||
|
||||
Output (color-coded):
|
||||
```
|
||||
========================================
|
||||
Environment Variables for: gitea
|
||||
========================================
|
||||
DB_HOST = postgres
|
||||
DB_NAME = gitea_db
|
||||
DB_PASSWD = secure_password_123
|
||||
DB_TYPE = postgres
|
||||
DB_USER = gitea
|
||||
DOMAIN = git.silveressence.net
|
||||
...
|
||||
```
|
||||
|
||||
*(Blue: variable names | Green: values)*
|
||||
|
||||
View injected environment variables for ALL services:
|
||||
|
||||
```bash
|
||||
slcompose env-all
|
||||
```
|
||||
|
||||
Output (color-coded):
|
||||
```
|
||||
========================================
|
||||
All Services and Their Environment Variables
|
||||
========================================
|
||||
|
||||
--- gitea ---
|
||||
DB_HOST = postgres
|
||||
DB_NAME = gitea_db
|
||||
...
|
||||
|
||||
--- portainer ---
|
||||
ADMIN_PASSWORD = secure_password
|
||||
...
|
||||
|
||||
--- postgres ---
|
||||
POSTGRES_DB = main_db
|
||||
...
|
||||
```
|
||||
|
||||
*(Blue: variable names | Green: values)*
|
||||
|
||||
**Use Cases:**
|
||||
- Verify secrets are properly injected
|
||||
- Debug missing or incorrect environment variables
|
||||
- Audit which services have access to which secrets
|
||||
- Troubleshoot authentication or configuration issues
|
||||
|
||||
## How Secret Injection Works
|
||||
|
||||
### Prerequisites
|
||||
|
||||
1. **Infisical Token**: Stored at `/etc/infisical/token`
|
||||
2. **Infisical Domain** (optional): Stored at `/etc/infisical/domain`
|
||||
3. **Secrets Path**: Each service has secrets at path `/<SERVICE_NAME>` in Infisical
|
||||
|
||||
Example: For `gitea` service, secrets must be at `/gitea` in Infisical.
|
||||
|
||||
### Injection Process
|
||||
|
||||
For each service, slcompose executes:
|
||||
|
||||
```bash
|
||||
infisical run \
|
||||
--token "$INFISICAL_TOKEN" \
|
||||
--env prod \
|
||||
--path="/$SERVICE_NAME" \
|
||||
--recursive \
|
||||
-- docker compose "$@"
|
||||
```
|
||||
|
||||
This:
|
||||
1. Authenticates with Infisical using the token
|
||||
2. Fetches all secrets from the specified path
|
||||
3. Recursively includes nested secrets
|
||||
4. Sets them as environment variables
|
||||
5. Passes them to the docker compose command
|
||||
|
||||
### Environment Variables
|
||||
|
||||
All secrets from Infisical are available as environment variables inside the docker compose execution context and are used by `docker-compose.yml` files.
|
||||
|
||||
Example `docker-compose.yml`:
|
||||
```yaml
|
||||
services:
|
||||
gitea:
|
||||
image: gitea/gitea:latest
|
||||
environment:
|
||||
DB_TYPE: postgres
|
||||
DB_HOST: postgres
|
||||
DB_NAME: ${DB_NAME} # Injected from Infisical
|
||||
DB_USER: ${DB_USER} # Injected from Infisical
|
||||
DB_PASSWD: ${DB_PASSWD} # Injected from Infisical
|
||||
```
|
||||
|
||||
## Service Directory Structure
|
||||
|
||||
Each service is a subdirectory in `/srv/docker/` containing:
|
||||
|
||||
```
|
||||
/srv/docker/gitea/
|
||||
├── docker-compose.yml
|
||||
├── README.md (optional)
|
||||
└── app.ini (optional, service-specific config)
|
||||
```
|
||||
|
||||
Services are discovered by the presence of `docker-compose.yml`.
|
||||
|
||||
## Systemd Integration
|
||||
|
||||
### Service File: `/etc/systemd/system/slcompose.service`
|
||||
|
||||
```ini
|
||||
[Unit]
|
||||
Description=SilverLinux Docker Orchestrator (slCompose)
|
||||
After=docker.service
|
||||
Requires=docker.service
|
||||
|
||||
[Service]
|
||||
Type=oneshot
|
||||
ExecStart=/usr/local/bin/slcompose boot
|
||||
RemainAfterExit=yes
|
||||
User=root
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
```
|
||||
|
||||
**Key Details:**
|
||||
- `Type=oneshot` — Runs once and exits (doesn't stay running)
|
||||
- `RemainAfterExit=yes` — Systemd remembers the service as "active" after boot completes
|
||||
- `After=docker.service` — Waits for Docker to start first
|
||||
- `Requires=docker.service` — Fails if Docker is not available
|
||||
- `WantedBy=multi-user.target` — Starts during normal multi-user boot
|
||||
|
||||
### Enable Auto-Boot
|
||||
|
||||
```bash
|
||||
sudo systemctl enable slcompose.service
|
||||
```
|
||||
|
||||
### Check Status
|
||||
|
||||
```bash
|
||||
sudo systemctl status slcompose.service
|
||||
```
|
||||
|
||||
### View Boot Logs
|
||||
|
||||
```bash
|
||||
sudo journalctl -u slcompose.service -n 100
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Missing Infisical Token
|
||||
|
||||
If `/etc/infisical/token` doesn't exist, slcompose exits with:
|
||||
```
|
||||
ERROR: Missing Infisical token at /etc/infisical/token
|
||||
```
|
||||
|
||||
### Service Not Found
|
||||
|
||||
If you try to manage a non-existent service:
|
||||
```bash
|
||||
slcompose up nonexistent
|
||||
```
|
||||
|
||||
Output:
|
||||
```
|
||||
ERROR: Service 'nonexistent' not found at /srv/docker/nonexistent
|
||||
```
|
||||
|
||||
### Docker Not Running
|
||||
|
||||
If Docker isn't available, slcompose waits and retries:
|
||||
```
|
||||
Waiting for Docker...
|
||||
Waiting for Docker...
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Services not starting on boot
|
||||
|
||||
1. Check if systemd service is enabled:
|
||||
```bash
|
||||
sudo systemctl is-enabled slcompose.service
|
||||
```
|
||||
|
||||
2. View boot logs:
|
||||
```bash
|
||||
sudo journalctl -u slcompose.service -n 50
|
||||
```
|
||||
|
||||
3. Test slcompose manually:
|
||||
```bash
|
||||
slcompose boot
|
||||
```
|
||||
|
||||
### Secrets not injected
|
||||
|
||||
1. Verify Infisical token exists:
|
||||
```bash
|
||||
cat /etc/infisical/token
|
||||
```
|
||||
|
||||
2. Test Infisical access:
|
||||
```bash
|
||||
infisical run --token "$(cat /etc/infisical/token)" --env prod --path=/gitea -- env | grep -v '^_'
|
||||
```
|
||||
|
||||
3. Check service paths in Infisical match service directory names
|
||||
|
||||
### Service fails to start
|
||||
|
||||
1. View detailed logs:
|
||||
```bash
|
||||
slcompose logs gitea
|
||||
```
|
||||
|
||||
2. Check docker-compose.yml for syntax errors:
|
||||
```bash
|
||||
cd /srv/docker/gitea && docker-compose config
|
||||
```
|
||||
|
||||
3. View full docker compose output:
|
||||
```bash
|
||||
cd /srv/docker/gitea && infisical run --token "$(cat /etc/infisical/token)" --env prod --path=/gitea -- docker compose up
|
||||
```
|
||||
|
||||
## Adding New Services
|
||||
|
||||
1. Create service directory:
|
||||
```bash
|
||||
mkdir -p /srv/docker/myservice
|
||||
```
|
||||
|
||||
2. Add `docker-compose.yml`:
|
||||
```bash
|
||||
cp template/docker-compose.yml /srv/docker/myservice/
|
||||
```
|
||||
|
||||
3. Create secrets in Infisical at path `/myservice`
|
||||
|
||||
4. Test:
|
||||
```bash
|
||||
slcompose up myservice
|
||||
slcompose logs myservice
|
||||
slcompose down myservice
|
||||
```
|
||||
|
||||
5. Service will automatically boot on next system startup
|
||||
|
||||
## Performance
|
||||
|
||||
- **Boot Time**: ~2 minutes for all 10+ services (includes Docker startup)
|
||||
- **Per-Service**: ~5-10 seconds per service startup
|
||||
- **Memory Overhead**: Minimal (orchestrator is bash script)
|
||||
|
||||
## Security
|
||||
|
||||
- **Secrets**: Never logged or displayed (only injected into containers)
|
||||
- **Tokens**: Read from files with appropriate permissions
|
||||
- **Docker Access**: Requires root/docker group membership
|
||||
- **Service Isolation**: Uses Docker networks to isolate services
