Hello everyone,
I wanted to use files from my Seafile server within Docker containers.
I started looking for existing image featuring a Seafile client on Docker Hub. There are some, but with issues such as non-existant/vague documentation or improper tagging.
I don’t know if it’s something that people are looking for, but I made one. It’s available at flowgunso/seafile-client in Docker Hub.
Example usage with docker-compose and for the docker cli are provided. Essentially, it runs seaf-cli sync, but you have to pass to the container your Seafile server URL, your credentials and the library ID you want to sync with. Then you can share the path /library as a volume to your containers for your own usages.
Feedback is welcome so I can keep improving it.
Quick informations
Please use flrnnc/seafile-client instead of flowgunso/seafile-client from now on.
This project is switching namespaces. The sources previously in flwgnso-docker/docker-seafile-client are now in flrnnc-oss/docker-seafile-client. The Docker image can still be found at flowgunso/seafile-client but it will be deprecated, the image flrnnc/seafile-client should be used instead.
flowgunso/seafile-client will still be updated until usage is low enough to be archived.
Supported tags
The versions match Seafile versions.
Features
- Synchronize one or more Seafile libraries.
- Support password protected librairies.
- Support two factor authentication.
- Configure upload and download limits.
- Skip SSL certificates.
- Set file ownership with user/group ID
The Docker image is built weekly to keep up with security updates.
Usage
Start a Seafile client
Docker command-line
The following command start the Seafile client with one library:
docker run \
-e SEAF_SERVER_URL="https://seafile.example/" \
-e SEAF_USERNAME="a_seafile_user" \
-e SEAF_PASSWORD="SoMePaSSWoRD" \
-e SEAF_LIBRARY="an-hexadecimal-library-uuid" \
-v path/to/library:/library \
-v path/to/client/data:/seafile \
flrnnc/seafile-client:latest
Docker Compose
The following Docker Compose start a Seafile client with two libraries, with one password protected:
version: "3"
services:
seafile-client:
image: flrnnc/seafile-client:latest
volumes:
- audio:/library/audio
- documents:/library/documents
- client:/seafile
environment:
SEAF_SERVER_URL: "https://seafile.example/"
SEAF_USERNAME: "a_seafile_user"
SEAF_PASSWORD: "SoMePaSSWoRD"
SEAF_LIBRARY_AUDIO: "audio-library-uuid"
SEAF_LIBRARY_AUDIO_PASSWORD: "auDioLiBRaRyPaSSWoRD"
SEAF_LIBRARY_DOCUMENTS: "documents-library-uuid"
volumes:
audio:
documents:
client:
Librairies
Environment variables allows librairies configuration, as shown in the examples above.
You can configure either a single librairy or multiple librairies.
Single library
To synchronize a single library, use the environment variables SEAF_LIBRARY and SEAF_LIBRARY_PASSWORD. The library will be synchronized in /library.
Multiple librairies
To synchronise multiple librairies, use the same environment variable as above but suffixed with a single identifier word. That word will be used for the library password and it’s synchronization path as well.
Hence, to synchronise a library identified as audio, the environment variables would be SEAF_LIBRARY_AUDIO for the library UUID and SEAF_LIBRARY_AUDIO_PASSWORD for the library password. The library will be then synchronized in /library/audio.
Identifiers allows to add as many libraries as possible. Identifier are single word only.
Environment variables
Environment variable allows you to configure the Seafile client.
SEAF_SERVER_URL
This variable is mandatory.
The Seafile server URL.
SEAF_USERNAME
This variable is mandatory.
The username for the Seafile account.
SEAF_PASSWORD
This variable is mandatory.
The password for the Seafile account.
SEAF_LIBRARY, SEAF_LIBRARY_[IDENTIFIER]
This variable is mandatory.
The UUID of the library, libraries to synchronize.
Replace [IDENTIFIER] with the a unique single word identifier for each library you want to synchronize.
SEAF_LIBRARY_PASSWORD, SEAF_LIBRARY_[IDENTIFIER]_PASSWORD
The password of the library, libraries to synchronize.
Replace [IDENTIFIER] with the a unique single word identifier for each library you want to synchronize corresponding to the SEAF_LIBRARY_[IDENTIFIER].
SEAF_2FA_SECRET
Two factor authentication is supported but your secret key must be provided. That key can be found on your Seafile web interface, only at the 2FA setup, when the QR code is shown. The secret key is embedded in the QR or available as a cookie.
SEAF_UPLOAD_LIMIT, SEAF_DOWNLOAD_LIMIT
Set upload and download speeds limits. Limits are in bytes.
SEAF_SKIP_SSL_CERT
Skip SSL certificates verifications.
Any string is considered true, omit the variable to set to false. Enable this if you have synchronization failures regarding SSL certificates.
UID, GID
Override the UID and GID for user running the Seafile client, hence the volume ownership.
Docker Secrets
All environments variable supports Docker Secrets, as environment variable variant suffixed with _FILE as files.
