Memos is an open-source, self-hosted memo hub with knowledge management and collaboration. I really like how Memos works and you’re sure to be impressed by its ease of use in various scenarios. You can also install a the Memos client on your Mobile Phone. In this step by step guide I will show you how to install Memos with PostgreSQL as database on your Synology NAS using Docker & Portainer. PostgreSQL has a well-constructed user management system which can handle multiple users and grant various levels of permission. SQLite is suitable for smaller databases. As the Memos database grows, the memory requirement also gets larger while using SQLite. Performance optimization is harder when using SQLite so PostgreSQL or MySQL is the solution. Note: If you want to install Memos without PostgreSQL as database, follow my other Memos Installation guide.

💡Note: This guide works perfectly with the latest Memos v0.22.5 release.

• STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it memos. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Now create two new folders inside the memos folder that you created at STEP 3 and name them data and db. Follow the instructions in the image below.
Note: Be careful enter only lowercase, not uppercase letters.

• STEP 5

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

• STEP 6

In the Name field type in memos. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

version: "3.9"
services:
  db:
    image: postgres:16
    container_name: Memos-DB
    hostname: memos-db
    mem_limit: 512m
    cpu_shares: 768
    security_opt:
      - no-new-privileges:true
    healthcheck:
      test: ["CMD", "pg_isready", "-q", "-d", "memos", "-U", "memosuser"]
      timeout: 45s
      interval: 10s
      retries: 10
    volumes:
      - /volume1/docker/memos/db:/var/lib/postgresql/data:rw
    environment:
      POSTGRES_DB: memos
      POSTGRES_USER: memosuser
      POSTGRES_PASSWORD: memospass
    restart: on-failure:5

  memos:
    image: ghcr.io/usememos/memos:stable
    container_name: Memos
    hostname: memos
    security_opt:
      - no-new-privileges:true
    healthcheck:
      test: wget --no-verbose --tries=1 --spider http://localhost:5230/
    user: 1026:100
    ports:
      - 5240:5230
    environment:
      MEMOS_DRIVER: postgres
      MEMOS_DSN: 'postgresql://memosuser:memospass@memos-db:5432/memos?sslmode=disable'
    volumes:
      - /volume1/docker/memos/data:/var/opt/memos:rw
    restart: on-failure:5
    depends_on:
      db:
        condition: service_healthy

Note: Before you paste the code above in the Web editor area below, change the value numbers for user with your own values. (Follow my step by step guide on how to do this.) 1026 is my personal UID value and 100 is my personal GID value. You have to type in your own values.

• STEP 7

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

• STEP 8

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

• STEP 9

Go back to STEP 1 or you will deal with karma 🙂

• STEP 10

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:5240 Add your own Username and Password then click Sign up. You can also change the default language and you have an option to switch the theme to Dark Mode. Follow the instructions in the image below.

• STEP 11

On the left sidebar click Settings, then Preferences to switch the theme to Dark Mode. Follow the instructions in the image below.

• STEP 12
