Configuring GitLab subgroup inheritance for consistent permissions

GitLab Permission Inheritance Features Implementation

To configure GitLab subgroup inheritance for consistent permissions using Pulumi, you will typically use a combination of GitLab's Group, GroupMembership, and potentially other related resources depending on the strictness and specifics of the permission settings you wish to apply.

The gitlab.Group resource is used to create and manage a GitLab group and its subgroups. It allows you to set properties such as visibility level, project creation level, and whether membership is locked to only group members (which is particularly relevant for maintaining consistent permissions).

The gitlab.GroupMembership resource is used to add users to a group with a specific access level. This is what you will use to ensure that permissions are inherited correctly by users within the group and any subgroups.

Here's a TypeScript program using Pulumi to manage GitLab subgroup permissions for consistency. This example assumes you have a GitLab token set up for authentication with the GitLab provider and have installed the @pulumi/gitlab package.

import * as pulumi from "@pulumi/pulumi";
import * as gitlab from "@pulumi/gitlab";

// Create a new group in GitLab.
const parentGroup = new gitlab.Group("parent-group", {
    name: "parent-group",
    path: "parent-group-path",
    // Other properties can be set as required, like description or visibility
});

// Create a subgroup in GitLab that inherits the parent group properties.
const childGroup = new gitlab.Group("child-group", {
    name: "child-group",
    path: "child-group-path",
    parentId: parentGroup.id,
    // Other properties could be set similarly to the parent group as needed.
});

// Add a user to the parent group with developer access level.
const groupMember = new gitlab.GroupMembership("group-member", {
    groupId: parentGroup.id,
    userId: 2, // Replace this with the actual user ID.
    accessLevel: gitlab.GroupMembershipAccessLevel.DEVELOPER,
});

// This is a basic example of managing a group and a subgroup with inheritance of permissions.
// You could add more subgroups or manage the membership at different levels as per your requirements.

// Export the group and subgroup paths to be easily accessible.
export const parentGroupPath = parentGroup.path;
export const childGroupPath = childGroup.path;

In this program:

We start by importing the required modules from Pulumi and GitLab.
We create a parent group using gitlab.Group, which is the top-level container for projects and subgroups. You can customize it with other properties such as the group's visibility, description, and more.
We then create a subgroup within the parent group by specifying the parentId property which establishes the inheritance.
A user is added to the parent group with a specific access level using gitlab.GroupMembership. This user will have that access level across all subgroups unless specifically overridden or changed in the subgroup settings or through direct subgroup membership.
We export parentGroupPath and childGroupPath for easy reference outside of Pulumi, such as using the paths in GitLab UI or API calls.

Remember to replace userId with the GitLab user ID you wish to add to the group. This program is a starting point, and you may need to extend it to fit the specific permissions and user setup your GitLab instance requires.
