ots-containers 0.3.2

Service orchestration for OneTimeSecret: Podman Quadlets and systemd service management

ots-containers

Service orchestration CLI for OneTimeSecret infrastructure.

Dual-purpose management tool:

• Container orchestration: Containerized OTS deployments via Podman Quadlets (systemd integration)
• Service management: Native systemd services for dependencies (Valkey, Redis)

Installation

With pipx (Recommended)

pipx install git+https://github.com/onetimesecret/ots-containers.git

With pip

pip install git+https://github.com/onetimesecret/ots-containers.git

From source

git clone https://github.com/onetimesecret/ots-containers.git
cd ots-containers
pipx install .

Usage

ots-containers --help
ots-containers --version

Instance Types

Three container types with explicit systemd unit naming:

Type	Unit Name	Identifier	Use
--web	onetime-web@{port}	Port number	HTTP servers
--worker	onetime-worker@{id}	Name/number	Background jobs
--scheduler	onetime-scheduler@{id}	Name/number	Scheduled tasks

Managing OTS Containers

# List all instances
ots-containers instances
ots-containers instances --json

# List by type
ots-containers instances --web
ots-containers instances --worker
ots-containers instances --scheduler

# Deploy instances
ots-containers instances deploy --web 7043 7044
ots-containers instances deploy --worker billing emails
ots-containers instances deploy --scheduler main

# Redeploy (regenerate quadlet and restart)
ots-containers instances redeploy                    # all running
ots-containers instances redeploy --web 7043         # specific

# Start/stop/restart
ots-containers instances start --web 7043
ots-containers instances stop --scheduler main
ots-containers instances restart                     # all running

# Status and logs
ots-containers instances status
ots-containers instances logs --web 7043 -f
ots-containers instances logs --scheduler main -f

# Enable/disable at boot
ots-containers instances enable --web 7043
ots-containers instances disable --scheduler main -y

# Interactive shell
ots-containers instances exec --web 7043

Managing systemd Services (Valkey, Redis)

# Initialize new service instance
ots-containers service init valkey 6379
ots-containers service init redis 6380 --bind 0.0.0.0

# Start/stop/restart
ots-containers service start valkey 6379
ots-containers service stop redis 6380
ots-containers service restart valkey 6379

# Status and logs
ots-containers service status valkey 6379
ots-containers service logs valkey 6379 --follow

# Enable/disable at boot
ots-containers service enable valkey 6379
ots-containers service disable redis 6380

# List available service packages
ots-containers service

Generating Cloud-Init Configurations

# Generate basic cloud-init config
ots-containers cloudinit generate > user-data.yaml

# Include PostgreSQL repository
ots-containers cloudinit generate --include-postgresql --postgresql-key /path/to/pgdg.asc

# Include Valkey repository
ots-containers cloudinit generate --include-valkey --valkey-key /path/to/valkey.gpg

# Validate configuration
ots-containers cloudinit validate user-data.yaml

Environment Variables

# Use a specific image tag
TAG=v0.23.0 ots-containers instances redeploy --web 7043

# Use a different image
IMAGE=ghcr.io/onetimesecret/onetimesecret TAG=latest ots-containers instances deploy --web 7044

Prerequisites

• Linux with systemd
• Podman installed and configured
• Python 3.11+

Server Setup

FHS-compliant directory structure:

OTS Container Configuration

/etc/onetimesecret/              # System configuration
├── config.yaml                  # Application configuration
├── auth.yaml                    # Authentication config
└── logging.yaml                 # Logging config

/etc/default/onetimesecret       # Environment file (shared by all instances)

/etc/containers/systemd/         # Quadlet templates (managed by tool)
├── onetime-web@.container
├── onetime-worker@.container
└── onetime-scheduler@.container

/var/opt/onetimesecret/          # Runtime data
└── deployments.db               # Deployment timeline (SQLite)

Service Configuration (Valkey/Redis)

/etc/valkey/                     # Valkey system configuration
├── valkey.conf                  # Default config template
└── instances/                   # Instance configs (created by tool)
    ├── 6379.conf
    └── 6379-secrets.conf        # Secrets file (mode 0640)

/var/lib/valkey/                 # Runtime data
└── 6379/
    └── dump.rdb

How It Works

Container Management

1. Quadlet templates: Writes systemd unit templates to /etc/containers/systemd/
2. Environment: Reads from /etc/default/onetimesecret
3. Secrets: Uses Podman secrets for sensitive values
4. Timeline: Records deployments to SQLite for audit and rollback

Service Management

1. Config files: Copies package defaults to instance-specific configs
2. Secrets: Creates separate secrets files with restricted permissions
3. Data directories: Creates per-instance data directories with correct ownership
4. systemd: Manages services using package-provided templates

Troubleshooting

# Check instance status
ots-containers instances status
systemctl status onetime-web@7043

# View logs
ots-containers instances logs --web 7043 -f
journalctl -u onetime-web@7043 -f

# Unified log filtering (all instance types)
journalctl -t onetime -f

# List all onetime systemd units
systemctl list-units 'onetime-*'

# Verify Quadlet templates
cat /etc/containers/systemd/onetime-web@.container

# Reload systemd after manual changes
systemctl daemon-reload

Development

# Editable install
git clone https://github.com/onetimesecret/ots-containers.git
cd ots-containers
pip install -e ".[dev,test]"

# Run tests
pytest tests/

# Run with coverage (CI threshold: 70%)
pytest tests/ --cov=ots_containers --cov-fail-under=70

# Pre-commit hooks
pre-commit install

Running as root

# Use full path
sudo /home/youruser/.local/bin/ots-containers instances status

# Or create symlink
sudo ln -s /home/youruser/.local/bin/ots-containers /usr/local/bin/ots-containers
