Seafile Server Docker image

Seafile server Docker image based on Alpine Linux.

Also in my Github repository you can find some usefull scripts for helping running containers.

Supported tags and respective Dockerfile links

• 6.2.3, latest - Seafile Server v6.2.3 - latest available version

Dockerfiles for older versions of Seafile Server you can find there.

Quickstart

To run container you can use following command:

docker run \  
  -v /home/docker/seafile:/home/seafile \  
  -p 127.0.0.1:8000:8000 \  
  -p 127.0.0.1:8082:8082 \  
  -ti sunx/seafile`

Containers, based on this image will automatically configure Seafile enviroment if there isn't any. If Seafile enviroment is from previous version of Seafile, container will automatically upgrade it to latest version (by calling Seafile upgrade scripts).

But I would advise you to do data backups before upgrading image (to not lose your data in case of bugs in upgrade logic of this image or Seafile upgrde scripts).

Detailed description of image and containers

Used ports

This image uses 2 tcp ports:

• 8000 - seafile port
• 8082 - seahub port

If you want to run seafdav (WebDAV for Seafile), then port 8080 will be used also.

Volume

This image uses one volume with internal path /home/seafile

I would recommend you use host directory mapping of named volume to run containers, so you will not lose your valuable data after image update and starting new container

Web server configuration

This image doesnt contain any web-servers, because you, usually, already have some http server running on your server and don't want to run any extra http-servers (because it will cost you some CPU time and Memory). But if you know some really tiny web-server with proxying support, tell me and I would be glad to integrate it to the image.

For Web-server configuration, as media directory location you should enter <volume/path>/seafile-server/seahub/media

In httpd-conf directory you can find lighttpd config example and haaproxy config example.

You can find Nginx and Apache configurations in official Seafile Server Manual.

Supported ENV variables

When you running container, you can pass several enviroment variables (with --env option of docker run command):

• INTERACTIVE=<0|1> - if container should ask you about some configuration values (on first run) and about upgrades. Default: 1
• SERVER_NAME=<...> - Name of Seafile server (3 - 15 letters or digits), used only for first run in non-interactive mode. Default: Seafile
• SERVER_DOMAIN=<...> - Domain or ip of seafile server, used only for first run in non-interactive mode. Default: seafile.domain.com
• SEAHUB=<fastcgi> - If seahub should be started in FastCGI mode (set it "fastcgi" for FastCGI mode or leave empty otherwise). Default: empty (not FastCGI mode).
• SEAFILE_FASTCGI_HOST=<ip> - Binding ip for seahub in FastCGI mode. Default: 127.0.0.1.
• HANDLE_SIGNALS=<0|1> - If container should properly handle signals like SIGHUP and SIGTERM (SIGTERM is sending on docker stop command, for example). If signals handling is turned on, then script will run infinity cycle for waiting signal, what, in theory, could slightly increase CPU consumption by container. Default: 1 (i.e. Turned on).

Useful commands in container

When you're inside of container, in home directory of seafile user, you can use following useful commands:

• seafile-fsck - check your libraries for errors (Originally seaf-fsck.sh is used for it)
• seafile-gc - remove ald unused data from storage of your seafile libraries (Originally seaf-gc.sh is used for it)
• seafile-admin start - start seafile and seahub daemons (if they were stopped)
• seafile-admin stop - stop seafile and seahub daemons
• seafile-admin reset-admin - reset seafile admin user and/or password
• seafile-admin setup - setup ccnet, seafile and seahub services (if they wasn't configured automatically by some reason)
• seafile-admin create-admin - create seafile admin user (if it wasn't created automatically by some reason)

Tips&Tricks and Known issues

• Make sure, that mounted data volume and files are radable and writable by container's seafile user(2016:2016).

• If you want to run seafdav, which is disabled by default, you can read it's manual. Do not forget to publish port 8080 after it.

• If you do not want container to automatically upgrade your Seafile enviroment on image (and Seafile-server) update, you can add empty file named .no-update to directory /home/seafile in your container. You can use docker exec <container_name> touch /home/seafile/.no-update for it.

• Container uses seafile user to run seafile, so if you need to do something with root access in container, you can use docker exec -ti --user=0 <container_name> /bin/sh for it.

• On first run (end every image upgrade) container will copy seahub directory from /usr/local/share/seahub to /home/seafile/seafile-server/seahub (i.e. to the volume), so it cost about 40Mb of space. I'm not sure if it could be changed without using webserver inside of container (But 40Mb of space isn't to much in our days, I think).

• At this moment most seafile scripts (which are located in /usr/local/share/seafile/scripts directory) aren't working properly, but I do not think that they are to usefull for this image (scripts seaf-fsck.sh and seaf-gc.sh are working correctly and also avaliable as /usr/local/bin/seafile-fsck and /usr/local/bin/seafile-gc).

• This image confugure sqlite-based Seafile server installation. If you want to run Seafile server witn MySQL\MariaDB, then you can configure it manually, or say to me about it and I'll add such configuration option.
