Installation

flatnotes provides flexible options for deployment, whether you prefer a managed service or self-hosting. For a quick and easy setup, you can deploy flatnotes through PikaPods, a hosted solution.

For those who prefer to self-host, Docker is the recommended method, offering robust and consistent deployment across various environments. Below are examples demonstrating how to get flatnotes up and running using Docker commands or Docker Compose.

Examples

Docker Run Command

To quickly launch flatnotes using a Docker run command, you can use the following:

docker run -d \
  -e "PUID=1000" \
  -e "PGID=1000" \
  -e "FLATNOTES_AUTH_TYPE=password" \
  -e "FLATNOTES_USERNAME=user" \
  -e 'FLATNOTES_PASSWORD=changeMe!' \
  -e "FLATNOTES_SECRET_KEY=aLongRandomSeriesOfCharacters" \
  -v "$(pwd)/data:/data" \
  -p "8080:8080" \
  dullage/flatnotes:latest

Docker Compose Example

For a more persistent and configurable setup, Docker Compose is an excellent choice. Here's an example docker-compose.yml file:

version: "3"

services:
  flatnotes:
    container_name: flatnotes
    image: dullage/flatnotes:latest
    environment:
      PUID: 1000
      PGID: 1000
      FLATNOTES_AUTH_TYPE: "password"
      FLATNOTES_USERNAME: "user"
      FLATNOTES_PASSWORD: "changeMe!"
      FLATNOTES_SECRET_KEY: "aLongRandomSeriesOfCharacters"
    volumes:
      - "./data:/data"
      # Optional. Allows you to save the search index in a different location: 
      # - "./index:/data/.flatnotes"
    ports:
      - "8080:8080"
    restart: unless-stopped
