Install Papermerge 3.5.2 on Ubuntu

First, create a new directory

mkdir ~/papermerge

According to the github page of Papermerge, the docker image for papermerge is called papermerge/papermerge. Pull it with docker by running:

sudo docker pull papermerge/papermerge:3.5.2

Since I want to use Docker Compose for the different microservices, I create a new compose.yaml file in the ~/papermerge directory (which you may need to create by mkdir ~/papermerge). The most basic file looks like this.

services:
  webapp:
    image: papermerge/papermerge:3.5.2
    environment:
      PAPERMERGE__SECURITY__SECRET_KEY: 12345
      PAPERMERGE__AUTH__USERNAME: admin
      PAPERMERGE__AUTH__PASSWORD: admin
    ports:
     - "12000:80"

It will probably throw some errors due to the usage of SQLite, but it should be accessible by opening a browser and going to localhost:12000

According to the compatibility matrix of Papermerge, we should use PostgreSQL 16.1 with papermerge:3.5.2. Pull it:

sudo docker pull postgres:16.1

In order to use PostgreSQL, we have to adapt the compose.yaml file.

  webapp:
    image: papermerge/papermerge:3.5.2
    environment:
      PAPERMERGE__SECURITY__SECRET_KEY: 12345
