Deploy Seafile in one click

What is Seafile?

Seafile is open-source software for syncing and sharing files, run in place of Dropbox or Google Drive. Files live in libraries: each one syncs to the desktop app on Windows, macOS and Linux, and the apps for iOS and Android browse and upload. Seafile keeps the history of every file, so an earlier version or a deleted file comes back, and a library can be encrypted with a password of its own, so the server stores only what it cannot read.

Libraries are shared with users and groups, read-only or to edit, and a share link gives a file or a folder to anyone, with a password and an expiry if you like; an upload link lets others drop files in. Seafile is known for syncing large numbers of files quickly: it transfers only the blocks of a file that changed.

This template runs the Community Edition from Seafile's official image, version 14.0, with MariaDB and a Redis cache. The databases and the admin, from the email and password you give, are made at the first start; sign-up stays off. SeaDoc, Seafile's online document editor, and its notification and metadata servers are not included.

Hosting Seafile on Pethost

1. You sign in to Pethost with a passkey, GitHub or Google. No machine yet? You pick a plan, and the link waits until it is ready.
2. New project opens at Seafile. You fill in what it asks for and click Create project: Email, Admin password.
3. In a minute or two Seafile is live at its own address with HTTPS. Its secrets are made at random, and its data is in the nightly backup.
4. It is a project like any other: you or your agent can change it, roll it back or restore it.

The template is this compose.yaml and the variables written into the project’s .env as it is created. Pethost runs the file as it is written.

Containers: seafile (seafileltd/seafile-mc:14.0-latest), db (mariadb:10.11), redis (redis:8-alpine).

Volumes, in the nightly backup: data, db.
