NOT UP TO DATE

This README is not up to date.

Description

This library was written to be able to use Incus with Python. There are some solutions out there but they either lack features or they are limiting in what our projects requires.

The library uses the Incus client installed on your machine to work. Meaning that you need to manually create remotes in your Incus for this library to work. This way, it's possible to use this library for remotes that requires more than just a certificate or a password.

Usage

Incus

The object Incus contains the methods to run commands on the system. It is also there that you can set the variable cwd in case you are running your code in a directory where you don't have the permission to write. You can also use the check() method to see if the library match the version of Incus.

Methods

• check() - Check Incus version. Raises IncusVersionException if the version does not match.
• run(cmd: str, **kwargs) - Execute cmd on the operation system and returns a dictionary {"data":result, "error":error}. kwargs is passed to subprocess.run().

Attributes

• cwd - Subprocess variable. Changes the execution path.
• remotes - Empty instance of Remote object to gain access to methods like list, get and exists.

Examples

import pyincus

pyincus.incus.cwd = "/"
pyincus.incus.check()

Model

Every object following this one inherite from Model and therefore can use any attribute or method from this object unless overridden.

Methods

• exists(name: str) - Return True if the object exists and False if not.
• list(filter: str) - filter is only used for Instance and NetworkForward. Returns a list of objects depending on the object that used this method.
• refresh() - Refresh the attributes.

Attributes

• attributes - Contains every variable from Incus object.
• name - Read only attribute associated to the Incus object.
• parent - Read only attribute associated to the Incus object.

Remote

Methods

• get(name: str) - Get a specific Remote object.
• rename(name: str) - Equivalent to incus remote rename

Attributes

• incus - Incus object.
• projects - Empty instance of Project object to gain access to methods like list, get and exists.
• addr - Read only attribute associated to the Incus object. Address of the remote object.
• project - Read only attribute associated to the Incus object. Default project name for the remote.
• public - Read only attribute associated to the Incus object. If the remote is public or private.

Examples

import pyincus

# List remotes locally installed on your computer.
print(pyincus.remotes.list())

# Check if the remote exists
if(pyincus.remotes.exists(name="local")):
 # Fetch the remote
