# Ansible Playbook for Pleroma
|
|
|
|
## Summary
|
|
|
|
This project was inspired by the official [Pleroma OTP installation guide](https://docs.pleroma.social/otp_en.html#content)
|
|
and contains a playbook which installs and configures Pleroma on a single Alpine Linux host.
|
|
It currently contains four roles, including:
|
|
|
|
- **init:** merges the default configuration with the user's custom configuration.
|
|
- **pleroma-postgres:** installs and configures the PostgreSQL database.
|
|
- **pleroma-backend:** installs and configures the Pleroma backend.
|
|
- **pleroma-nginx:** installs and configures Nginx, creates SSL certificates using Let's Encrypt and adds support for proving your Pleroma site with Keybase.
|
|
|
|
This project is currently used to manage my personal instance at https://fedi.dananglin.me.uk.
|
|
|
|
## Additional Features
|
|
|
|
- **Let's Encrypt support:** This playbook creates a SSL certificate using Let's Encrypt.
|
|
- **Keybase support:** Pleroma does not support Keybase out of the box but you can still prove that your ownership of your Pleroma site.
|
|
- **Custom default background:** Specify an image to use as the default background of your Pleroma site.
|
|
|
|
## Requirements
|
|
|
|
- A controller host running [Ansible](https://www.ansible.com/) version 2.8+.
|
|
- `make` and `openssl` on the controller host which are used to generate secret values.
|
|
- A target host running [Alpine Linux](https://www.alpinelinux.org/) version 3.10.
|
|
- A (sub)domain which resolves to the IP address of the target host.
|
|
|
|
## Configuration
|
|
|
|
Here's an [example configuration file](./examples/host_vars/pleroma-01.yml) that you can use as a starting point to configure your Pleroma instance.
|
|
This typically goes in your host\_vars directory but you can place it in your group\_vars directory or even inside your playbook instead.
|
|
The [default configuration is located here](./roles/init/defaults/main.yml) which the `init` role will merge with your configuration.
|
|
Any fields you configured will overwrite the default.
|
|
|
|
More documentation on the configuration will be available soon.
|
|
|
|
## Secrets
|
|
|
|
Following secrets are not included in the default configuration and must be generated before running the playbook:
|
|
|
|
- **secretKeyBase:** This is used to configure the `secret_key_base` in Pleroma. This is used to sign and verify cookies.
|
|
- **signingSalt:** This is used to configure the `signing_salt` in Pleroma. This is used with the `secret_key_base` to generate a key for signing and verifying cookies.
|
|
- **vapid key pair for web push encryption:** This is a private and public key pair so that Pleroma can used [VAPID](https://tools.ietf.org/html/rfc8292) to identify itself to the web push service (for notifications in the browser).
|
|
- **database password:** This is used to authenticate access to the Pleroma database.
|
|
|
|
Insstructions on generating these can be found in the guide below.
|
|
It is recommended to encrypt these secrets using [Ansible Vault](https://docs.ansible.com/ansible/latest/user_guide/vault.html).
|
|
|
|
## Guide to setting up and running the playbook
|
|
|
|
- Copy the [example inventory file](examples/inventory.yml) to the root of this project.
|
|
```bash
|
|
$ cp examples/inventory.yml ./
|
|
```
|
|
|
|
- In the inventory file you've just copied change **\<ANSIBLE\_HOSTS\>** to the IP address of the target host and change **\<ANSIBLE\_USER\>** to the user on the target host with sudo priviledges.
|
|
|
|
- Copy the [example playbook file](examples/site.yml) to the root of the project.
|
|
```bash
|
|
$ cp examples/site.yml ./
|
|
```
|
|
|
|
- Copy the [example host\_vars](examples/host_vars) directory to the root of this project. This directory contains the file used to configure your Pleroma instance. You should review and edit the configuration before running the playbook.
|
|
```bash
|
|
$ cp -a examples/host_vars ./
|
|
```
|
|
|
|
- Generate the secret key base and add this to the to the `secretKeyBase` field (don't forget to uncomment this).
|
|
```bash
|
|
$ make secret_key_base
|
|
```
|
|
|
|
- Generate the signing salt and add this to the `signingSalt` field.
|
|
```
|
|
$ make signing_salt
|
|
```
|
|
|
|
- Generate the key pair for web push encryption and add these to `privateKey` and `publicKey` fields.
|
|
```
|
|
$ make vapid_key_pair
|
|
```
|
|
|
|
- Create a password for your database and add this to the `password` field under `db`.
|
|
|
|
- Optional (but recommended): Use Ansible Vault to encrypt the generated secret values above.
|
|
|
|
- Run the playbook using one of the following commands:
|
|
```bash
|
|
# If you're not using Ansible vault
|
|
$ ansible-playbook -i inventory.yml site.yml
|
|
|
|
# If you're using Ansible vault and want to be prompted for the password
|
|
$ ansible-playbook -i inventory.yml site.yml --ask-vault-pass
|
|
|
|
# If you're using Ansible vault and a password file
|
|
$ ansible-playbook -i inventory.yml site.yml --vault-id /path/to/your/password-file
|
|
```
