Seafile is a free self-hosted personal cloud solution like Dropbox. It provides excellent performance and solid security. Seafile can be installed on Docker as a container, or as a stand-alone application as well. In this tutorial, we will see how to install the Seafile server on Docker.

Seafile Docker container

Make sure you have installed Portainer & Docker before proceeding. We will add a docker stack of Seafile with MariaDB (as a data store).

1. On Portainer, add a new Network for seafile container(s) to use. I am naming it as seafile-net and set the driver as bridge.

2. Add a new stack with name Seafile. Leave the Build method as Web Editor.

3. Copy the below compose file content into the Web editor. Do not deploy the stack yet, I’ll explain what some important configurations do in the following steps. You can customize them if required.

version: "2"

services:
  db:
    image: mariadb
    container_name: seafile-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=changeme  
      - MYSQL_LOG_CONSOLE=true
    volumes:
      - /opt/container/seafile-mysql/db:/var/lib/mysql
    networks:
      - seafile-net

  memcached:
    image: memcached
    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      - seafile-net
          
  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    ports:
      - "80:80"
#     - "443:443"
    volumes:
      - /opt/container/seafile/seafile-data:/shared
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=changeme
      - TIME_ZONE=Etc/UTC
      - SEAFILE_ADMIN_EMAIL=me@example.com
      - SEAFILE_ADMIN_PASSWORD=changeme
      - SEAFILE_SERVER_LETSENCRYPT=false
      - SEAFILE_SERVER_HOSTNAME=seafile.example.com
    depends_on:
      - db
      - memcached
    networks:
      - seafile-net

networks:
  seafile-net:
    external:
      name: seafile-net 

MariaDB Database container

4. We will configure a DB store in MariaDB for Seafile to use. Start with setting the root password at MYSQL_ROOT_PASSWORD, and map a folder for DB storage. Finally, point it to the network seafile-net we created in Step 1.

Memcached container

5. Seafile uses Memcached as a cache for better performance. This section adds it and you don’t have to customize anything here unless you want to.

Seafile container

6. The default Container port for Seafile hub is 80. You can map it to anything you want. (If you are exposing enabling SSL then you would want to map the port 443)

7. After that add a file storage location for Seafile. This is where the web and user files are stored.

8. Next, add the db host name and user credentials we entered earlier in MariaDB.

9. Set a default admin email and password to manage this Seafile server.

10. This is optional and needed only if you are enabling HTTPS. Make the SEAFILE_SERVER_LETSENCRYPT variable true to retrieve an SSL automatically from the LetsEncrypt server. You would also need to add the hostname in the next variable.

11. Click deploy and go to http://hostname or https://hostname on your web browser. Then login with the default admin credentials set up earlier.

That is it, now you can start using your Seafile server. You can also connect to your account via mobile apps and desktop sync clients.
