Ansible Playbook for Papermerge DMS

In this repository are playbooks for production deployment, data backup and data restoration of Papermerge 3.

Papermerge instance is deployed behind Traefik reverse proxy. Traefik takes care of TLS certificates.

Choose one of following options:

• option 1: install Papermerge with PostgreSQL database
• option 2: install Papermerge with PostgreSQL + PgBouncer
• option 3: install Papermerge with MariaDB as database

Requirements

• Remote host with ssh access running Debian12 / Ubuntu 22.04 LTS
• On your local computer you need to have ansible == 2.15

Secrets

This repository does not include "secrets" file. Secrets file contains all sensitive (paswords, api tokens) info.

You need to create secrets file e.g. in group_vars folder and place following content:

secret_key: ...
superuser_password: ...
database_url: ...
db_pass: ...
cloudflare_api_key: ...
traefik_api_password: ...

Option 1 / PostgreSQL

Make sure database_url in your secrets files matches database related options in group_vars/all (db_user, db_name). Also port number database_url should match the one in db_postgres/vars/main.yml.

database_url should have following format:

postgresql://<user>:<pass>@db:5432/<dbname>

Install Papermerge DMS with PostgreSQL:

$ ansible-playbook deploy.yml

Or if you already deployed previously, and want to redeploy only specific docker image of Papermerge (other services are up and running):

$ ansible-playbook deploy.yml --tags paper

Application will be accessible via https://<acme_domain> acme_domain is variable you set in group_vars/all e.g. trusel.net

Option 2 / PostgreSQL + PgBouncer

In this setup application will connect to the database via pgbouncer, this means that database_url should point to pgbouncer.

Your database_url should look like:

postgresql://<user>:<pass>@pgbouncer:6432/<dbname>

Install Papermerge DMS with PostgreSQL and PgBouncer:

$ ansible-playbook deploy_with_pgbouncer.yml

Application will be accessible via https://<acme_domain> acme_domain is variable you set in group_vars/all e.g. trusel.net

Option 3 / MariaDB

For Mysql/MariaDB database_url should have following format:

mysql://<user>:<pass>@db:3306/<dbname>

Install Papermerge DMS with MariaDB:

$ ansible-playbook deploy_with_mariadb.yml

OAuth 2.0 Authentication with Google Provider

This works only for Papermerge version >= 3.1 You need to set auth_mode=google and define following variables:

• google_client_id: <oauth2 client id>
• google_client_secret: <oauth2 client secret>
• google_redirect_uri: https://<your-domain>/google/callback

OAuth 2.0 Authentication with GitHub Provider

This works only for Papermerge version >= 3.1

You need to set auth_mode=github and define following variables:

• github_client_id: <oauth2 client id>
• github_client_secret: <oauth2 client secret>
• github_redirect_uri: https://<your-domain>/github/callback

auth_mode

auth_mode is a comma separated list of authentication modes. If you want to add both github and google oauth providers, set auth_mode=github,google

There are three possible values:

• db (default one)
• github
• google
• ldap

ldap mode is exclusive, which means that you can set only auth_mode=ldap alone.

Backup

In order to create a backup:

$ ansible-playbook backup.yml

Restore

In order to restore the backup:

ansible-playbook restore.yml --extra-vars "backup_file=/backup/backup_20_11_2023-07_33_03.tar.gz"

The backup file path is the one from inside docker container.
