# Alpine Linux
|
||||
Alpine Linux is a lightweight and secure [Linux](Linux.md) operating system designed for security, simplicity, and resource efficiency. It is particularly popular for use in containerized environments and embedded systems. In this personal knowledge base document, we will explore the key features, benefits, and use cases of Alpine Linux.

Alpine Linux is a lightweight and secure [Linux](Linux.md) operating system designed for security, simplicity, and resource efficiency. It is particularly popular for use in containerized environments and embedded systems. Alpine does not use [Systemd](Systemd.md), instead it uses [openrc](openrc.md).
|
||||
|
||||
Here are some of the key features of Alpine Linux:
|
||||
- Lightweight: Alpine Linux is designed to be as small and simple as possible, with a small footprint and minimal dependencies. The base image is typically around 5 MB in size.

## Use Cases
|
||||
|

Here are some of the common use cases for Alpine Linux:
|
||||
- Containerized environments: Alpine Linux is widely used as a base image for containerized applications due to its small size and focus on security.
|
||||
- Embedded systems: Alpine Linux is popular for use in embedded systems due to its small size and resource efficiency.

# openRC
|
||||
#wip #🐇
|
||||
OpenRC is a dependency-based init system that works with the system-provided init program
|
||||
|
||||
The following commands are available to manage the init system:
|
||||
|
||||
- Basics:
|
||||
```shell
|
||||
rc-update add <service> <runlevel>
|
||||
|
||||
rc-update del <service> <runlevel>
|
||||
|
||||
rc-service <service> <start stop restart>
|
||||
```
|
||||
- To check services and their set runlevels:
|
||||
```shell
|
||||
rc-status
|
||||
```
|
||||
|
||||
## rc-update usage
|
||||
```
|
||||
Usage: rc-update [options] add service <runlevel>
|
||||
rc-update [options] del service <runlevel>
|
||||
rc-update [options] show
|
||||
|
||||
Options: [suChqv]
|
||||
-s, --stack Stack a runlevel instead of a service
|
||||
-u, --update Force an update of the dependency tree
|
||||
-h, --help Display this help output
|
||||
-C, --nocolor Disable color output
|
||||
-v, --verbose Run verbosely
|
||||
-q, --quiet Run quietly
|
||||
```
|
||||
|
||||
## rc-status usage
|
||||
```
|
||||
Usage: rc-status [options] [runlevel1] [runlevel2] ...
|
||||
|
||||
Options: [aclrsuChqv]
|
||||
-a, --all Show services from all run levels
|
||||
-c, --crashed Show crashed services
|
||||
-l, --list Show list of run levels
|
||||
-r, --runlevel Show the name of the current runlevel
|
||||
-s, --servicelist Show service list
|
||||
-u, --unused Show services not assigned to any runlevel
|
||||
-h, --help Display this help output
|
||||
-C, --nocolor Disable color output
|
||||
-v, --verbose Run verbosely
|
||||
-q, --quiet Run quietly
|
||||

|
||||
|
||||
## rc-service usage
|
||||
```
|
||||
Usage: rc-service [options]
|
||||
|
||||
Options: [e:ilr:ChqVv]
|
||||
-e, --exists <arg> tests if the service exists or not
|
||||
-i, --ifexists if the service exists then run the command
|
||||
-l, --list list all available services
|
||||
-r, --resolve <arg> resolve the service name to an init script
|
||||
-h, --help Display this help output

||||
-C, --nocolor Disable color output
|
||||
-V, --version Display software version
|
||||
-v, --verbose Run verbosely
|
||||
-q, --quiet Run quietly
|
||||
```
|
||||
|
||||
## rc usage
