Manual Upgrade

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

  1. First, stop and remove the old container:

    docker stop memos && docker rm memos
  2. Although optional, it's recommended to back up your database:

    cp -r ~/.memos/memos_prod.db ~/.memos/memos_prod.db.bak


    tar -czvf ~/.memos/memos_prod.db_$(date +%Y%m%d).tar.gz ~/.memos/memos_prod.db
  3. Next, pull the latest memos image:

    docker pull neosmemo/memos:stable
  4. Finally, start 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.

Automatic Upgrades

Memos can be automatically upgraded by Watchtower.


It's advised that you use a custom automatic data backup strategy in parallel to automatic updates. This way, you can easily roll back to a previous version if needed.

While automatic updates usually work well, they can cause issues if you use the latest or even the stable tag, as they can receive major and minor version upgrades with database schema changes.


Patch version upgrades are safe, as they only contain bug fixes and small changes to the codebase.

To only receive Patch version updates automatically, use a Major.Minor tag like 0.22.

The following is a sample docker-compose.yml that spins up Memos and Watchtower. Watchtower will check for updates every day at 4 AM. If you need to set a custom schedule, write your own cron expression.

    image: neosmemo/memos:0.22
    labels: { com.centurylinklabs.watchtower.enable: true }
    container_name: memos
    hostname: memos
    restart: unless-stopped
    ports: ["5230:5230"]
      - ~/.memos:/var/opt/memos

    image: containrrr/watchtower:1.7.1
    container_name: watchtower
    restart: unless-stopped
    command: --stop-timeout 60s --cleanup --schedule "0 0 4 * * *" --label-enable
    volumes: ["/var/run/docker.sock:/var/run/docker.sock"]

By setting up Watchtower with --label-enable and the Memos container with the label com.centurylinklabs.watchtower.enable: true, only the Memos container will be updated, leaving other containers untouched.
