# Ansible Role for Generating Subuids & Subgids

Creates subuid & subgid mappings for users.

Inspired from this blog article 

## Install

`roles/requirements.yml`

```bash

---

roles:

  - name: subuid_subgid

    version: main

    src: [email protected]:rwxd/ansible-role-subuid_subgid.git

    scm: git

```

`ansible.cfg`

```bash

[defaults]

roles_path=./roles

```

Get requirements with `ansible-galaxy role install -r roles/requirements.yml`

## Usage

A `subid_users` variable is required e.g.:

```yaml

- name: Set users

  set_fact:

    subid_users:

      - peter

      - james

- name: Generate subuids & subgids

  include_role:

    name: subuid_subgid

```

`/etc/subuid` will contain

```bash

peter:65929216:65536

james:65470464:65536

```

`/etc/subgid` will contain

```bash

peter:65929216:65536

james:65470464:65536

```

### Configure the size of the bitshift

UID's can be not larger than 2^32. So if you have large UID's you may want to use a smaller bitshift.

```yaml

- name: Generate subuids & subgids

  include_role:

    name: subuid_subgid

  vars:

    subuid_bitshift: 16

    subgid_bitshift: 16

```
