inmanta-module-files 2.1.0

Simple module containing various types of resource to manage files.

inmanta-module-files

This package is an adapter that is meant to be used with the inmanta orchestrator: https://docs.inmanta.com

Features

This module allows to manage files, on a unix host. It contains the following resources:

1. files::Directory: to manage a directory, its existence, permissions and ownership.
2. files::TextFile: to manage a simple text file, its existence, content, permissions and ownership. This should not be used for big files, as the content of the file is embedded in the resource itself.
3. files::HostFile: to manage hosts file entries (i.e. /etc/hosts), but allowing the file to be managed by other tools. The resource makes sure to only modify the entries defined in its desired state and leave the rest untouched.
4. files::JsonFile and files::SharedJsonFile: to manage json file entries. Similarly to files::HostFile, only change in the file what is present in the desired state. The file can then still be modified by other tools.
5. files::SystemdUnitFile: an entity representing a unit file, which exposes it most useful properties directly in the model. After being exported, this resource becomes nothing more than a text file.
6. files::Symlink: to manage a symlink, its existence and ownership.

Example

The following example makes sure that the directory /tmp/test/a exists, and creates a text file in it.

import mitogen
import files

import std

host = std::Host(
    name="localhost",
    os=std::linux,
    via=mitogen::Local(),
)

dir = files::Directory(
    host=host,
    path="/tmp/test/a",
    # The directory that is managed is /tmp/test/a, but the resource
    # will also make sure that any of its parent directories exists as well
    create_parents=true,
)

file = files::TextFile(
    host=host,
    path=f"{dir.path}/file.txt",
    content="test",
    # The file requires the directory to be created first
    requires=[dir],
)
