service-config-foundry 0.1

Helps create non-templated systemd services.

service-config-foundry

service-config-foundry is a Python-based library that simplifies the process of creating, updating, replacing, and deleting systemd service files for Linux users. With this tool, you can easily manage systemd services programmatically, reducing the complexity of writing and maintaining service configuration files manually.

Features

• Create and manage non-templated systemd service files
• Support for various systemd file types including .service, .timer, .socket, .mount, and more
• Programmatic control over file attributes and configurations
• Replace and update existing services without conflicts
• Fully integrated Python API with no external dependencies

Installation

You can install the library using pip directly from the GitHub repository:

pip install git+https://github.com/yushdotkapoor/service-config-foundry.git

Alternatively, clone the repository to get started:

git clone https://github.com/yushdotkapoor/service-config-foundry.git
cd service-config-foundry

Usage

Below are detailed examples of how to use service-config-foundry to create and manage systemd files of various types.

Example: Creating a Service, Timer, and Socket

from service import Service
from service_location import ServiceLocation

# Create a new service instance
service = Service("example", service_location=ServiceLocation.GLOBAL, auto_start=False, enable_at_startup=False, force_overwrite=False)

# Configure the service file
service_file = service.service_file
service_file.unit.description = "Example service for demonstration purposes"
service_file.service.user = "yushrajkapoor"
service_file.service.exec_start = "echo Hello, world >> /tmp/example.log"
service_file.install.wanted_by = "multi-user.target"

# Configure the timer file
timer_file = service.timer_file
timer_file.unit.description = "Example timer for demonstration purposes"
timer_file.timer.on_calendar = "*-*-* *:00:00"
timer_file.install.wanted_by = "timers.target"

# Configure the socket file
socket_file = service.socket_file
socket_file.unit.description = "Example socket for demonstration purposes"
socket_file.socket.listen_stream = "/run/example.sock"
socket_file.install.wanted_by = "sockets.target"

# Create or update the service, timer, and socket files
service.update()

# Enable the service to start at boot time
service.enable_service_at_startup()

# Start the service
service.start_service()

# Display the status of the service
service.status()

Output Files

example.service

[Unit]
Description = Example service for demonstration purposes

[Service]
User = yushrajkapoor
ExecStart = echo Hello, world >> /tmp/example.log

[Install]
WantedBy = multi-user.target

example.timer

[Unit]
Description = Example timer for demonstration purposes

[Timer]
OnCalendar = *-*-* *:00:00

[Install]
WantedBy = timers.target

example.socket

[Unit]
Description = Example socket for demonstration purposes

[Socket]
ListenStream = /run/example.sock

[Install]
WantedBy = sockets.target

Example: Replacing an Existing Service

If you want to replace an existing service configuration, you can use the replace() method. This ensures that any old files are removed and replaced with the new configuration.

# Replace the existing service configuration
service.replace()

This is particularly useful when you want to ensure that your updates overwrite any conflicting configurations from previous versions of the service.

Example: Creating Mount and Automount Files

# Configure the mount file
mount_file = service.mount_file
mount_file.unit.description = "Example mount for demonstration purposes"
mount_file.mount.what = "/dev/sda1"
mount_file.mount.where = "/mnt/example"
mount_file.mount.type = "ext4"
mount_file.install.wanted_by = "multi-user.target"

# Configure the automount file
automount_file = service.automount_file
automount_file.unit.description = "Example automount for demonstration purposes"
automount_file.automount.where = "/mnt/example"
automount_file.install.wanted_by = "multi-user.target"

# Create or update the files
service.update()

example.mount

[Unit]
Description = Example mount for demonstration purposes

[Mount]
What = /dev/sda1
Where = /mnt/example
Type = ext4

[Install]
WantedBy = multi-user.target

example.automount

[Unit]
Description = Example automount for demonstration purposes

[Automount]
Where = /mnt/example

[Install]
WantedBy = multi-user.target

Example: Creating Swap and Path Files

# Configure the swap file
swap_file = service.swap_file
swap_file.unit.description = "Example swap for demonstration purposes"
swap_file.swap.what = "/swapfile"
swap_file.install.wanted_by = "multi-user.target"

# Configure the path file
path_file = service.path_file
path_file.unit.description = "Example path for demonstration purposes"
path_file.path.path_exists = "/tmp/example"
path_file.install.wanted_by = "multi-user.target"

# Create or update the files
service.update()

example.swap

[Unit]
Description = Example swap for demonstration purposes

[Swap]
What = /swapfile

[Install]
WantedBy = multi-user.target

example.path

[Unit]
Description = Example path for demonstration purposes

[Path]
PathExists = /tmp/example

[Install]
WantedBy = multi-user.target

Example: Creating Slice and Scope Files

# Configure the slice file
slice_file = service.slice_file
slice_file.unit.description = "Example slice for demonstration purposes"

# Configure the scope file
scope_file = service.scope_file
scope_file.unit.description = "Example scope for demonstration purposes"
scope_file.scope.slice = "example.slice"

# Create or update the files
service.update()

example.slice

[Unit]
Description = Example slice for demonstration purposes

example.scope

[Unit]
Description = Example scope for demonstration purposes

[Scope]
Slice = example.slice

Deleting a Service

To delete a service and its associated files:

service.delete()

This will remove all files matching the service name in the systemd directory.
