This document provides a comprehensive guide on deploying Memos with Docker, including installation and upgrading instructions.

Prerequisites

Before proceeding with Memos installation, ensure you meet the following prerequisites:

A server with Docker installed

Docker Run

To set up Memos using docker run, execute the following one command to start Memos:

docker run -d \
  --init \
  --name memos \
  --publish 5230:5230 \
  --volume ~/.memos/:/var/opt/memos \
  neosmemo/memos:stable

This command will launch Memos in the background, exposing it on port 5230. Data will be stored in the ~/.memos/ directory. You can customize the port and the data directory path as needed.

Parameter Options

mode (-m, --mode):
- Values: "prod" or "dev"
- Default: "prod"
- Purpose: Sets the mode of the server, influencing its runtime behavior. Options include production ("prod"), development ("dev").
addr (-a, --addr):
- Value: String representing the server address.
- Default: Empty string.
- Purpose: Specifies the address on which the server will listen for incoming connections.
port (-p, --port):
- Value: Integer representing the server port.
- Default: 8081.
- Purpose: Sets the port on which the server will be accessible.
data (-d, --data):
- Value: String representing the data directory.
- Default: Empty string.
- Purpose: Specifies the directory where Memos will store its data.
driver (--driver):
- Value: String representing the database driver. We currently support "sqlite", "mysql" and "postgres".
- Default: "sqlite"
- Purpose: Sets the database driver to be used by Memos.
dsn (--dsn):
- Value: String representing the database source name. Only applicable when using the MySQL or PostgreSQL driver.
- Default: Empty string.
- Purpose: Specifies the database source name (DSN) for connecting to the database.
frontend (--frontend)
- Value: Boolean (true/false).
- Default: true.
- Purpose: Enables or disables the frontend. When disabled, Memos will not serve the frontend. You can deploy the frontend separately and set this flag to false.
origins (--origins)
- Value: String array representing the allowed origins.
- Default: Empty array.
- Purpose: Sets the allowed origins for CORS requests. If empty, all origins are allowed.

Docker Compose

To deploy Memos using docker compose, create a docker-compose.yml file with the following configuration:

version: "3.0"
services:
  memos:
    image: neosmemo/memos:stable
    container_name: memos
    volumes:
      - ~/.memos/:/var/opt/memos
    ports:
      - 5230:5230

Now, execute docker-compose up -d to initiate Memos. While editing the port and data directory is possible, only modify the first port (e.g., 8081:5230) to specify an alternative port. The second port designates the port Memos is listening on inside the container. The same principle applies to directory paths, where the first path represents the location on your host system, and the second path signifies the directory inside the container.

Upgrading Memos

To upgrade Memos to the latest version, perform the following steps:

First, stop and remove the old container:
```
docker stop memos && docker rm memos
```
Although optional, it's advisable to back up your database:
```
cp -r ~/.memos/memos_prod.db ~/.memos/memos_prod.db.bak
```
Next, pull the latest memos image:
```
docker pull neosmemo/memos:stable
```
Finally, initiate Memos by following the steps outlined in the Docker Run section. Your upgraded Memos instance will now be up and running with the latest enhancements and features.
