Seafile 4 for Docker

Seafile is a "next-generation open source cloud storage
with advanced features on file syncing, privacy protection and teamwork".

This Dockerfile install an environment to run seafile.
Seafile will be autoconfigurated with the default parameters and running at the container startup

Setup Db

You can use a mysql/mariadb container or any other database you already have installed.

Run it

docker run -d --name="mariadb" sudokeys/mariadb

Get mariadb root password

docker logs mariadb 

Setup Seafile

The image install seafile and configure it according to the default environment variables in the Dockerfile and the variables you give it at runtime.

Seafile can create his own databases or it can be installed with existing (empty) ones.

In any case you need to provide at least the IP adress of the interface to listen on and some user/password info

If you don't choose a password it will be randomly generated if possible and written to "docker logs"

###Auto create databases with seafile
If you want seafile to automatically create databases for you, you need to provide him the root user and password.

You might also want to provide a seahub admin email if you don't want the default one

example :

docker run -d --name "myseafile" \
  -p 10001:10001 -p 12001:12001 -p 8000:8000 -p 8082:8082 \
  --link mariadb:mysql-container \
  -e "CCNET_IP=192.168.0.100" -e "MYSQL_ROOT_USER=dataadmin" \ 
  -e "MYSQL_ROOT_PASSWORD=rootpass" -e "SEAHUB_ADMIN_EMAIL=seafileadmin@yourdomain.com" \
  sudokeys/seafile 

###Existing databases (no root password needed)
If you want to use existing databases you need to provide the mysql user and password for those databases and their names (or the script will look for the default ones).

:warning: Databases must be empty at seafile installation or it will crash!

For example, you could use

docker run -d --name "myseafile" \
  -p 10001:10001 -p 12001:12001 -p 8000:8000 -p 8082:8082 \
  --link mariadb:mysql-container \
  -e "CCNET_IP=192.168.0.100" -e "EXISTING_DB=true" -e "SEAHUB_ADMIN_EMAIL=seafileadmin@yourdomain.com" \
  -e "MYSQL_USER=myseafileuser" -e "MYSQL_PASSWORD=myseafilepass" \
  sudokeys/seafile   

##Auto-configure Nginx
Run nginx first with a volume where you want to store static files

docker run -d --name nginx -p 80:80 -p 443:443 -v /opt/seafile/nginx sudokeys/nginx

then run seafile with --volumes-from to allow it to create the configuration file, ssl certificates and copy his static files

For SEAFILE_IP you can use the static ip of the container (not very flexible), the host ip if you expose ports, or some dns discovery like skydock/skydns (used in this example)

 docker run -d --name "myseafile"  -e fcgi=true -e autonginx=true -e "CCNET_IP=myfiles.mydomain.com" \
 -e "MYSQL_ROOT_USER=root" -e "MYSQL_ROOT_PASSWORD=rootpass" \
 -e "SEAHUB_ADMIN_EMAIL=admin@yourdomain.com" -e "SEAFILE_IP=myseafile.seafile.dev.docker" \
 -e "MYSQL_HOST=mydatabase.mariadb.dev.docker" --volumes-from nginx seafile

just restart nginx after each new seafile container launch to make it reload his configuration

docker restart nginx

You can specify a SSL key and certificate for nginx. If not specified an autosigned key wille be generated. If you want to use you own key you have to attach a host volume containing your SSL key and cert, and pass the path to those in env variables NGINX_SSL_KEY and NGINX_SSL_CERT
I use sudokeys/nginx container which export /etc/nginx volume by default. Then I use below command:

 docker run -d --name "myseafile"  -e fcgi=true -e autonginx=true -e "CCNET_IP=myfiles.mydomain.com" \
 -e "MYSQL_ROOT_USER=root" -e "MYSQL_ROOT_PASSWORD=rootpass" \
 -e "SEAHUB_ADMIN_EMAIL=admin@yourdomain.com" -e "SEAFILE_IP=myseafile.seafile.dev.docker" \
 -e "MYSQL_HOST=mydatabase.mariadb.dev.docker" \
 -e "NGINX_SSL_KEY=/etc/nginx/certs/myseafile.key" -e "NGINX_SSL_CERT=/etc/nginx/certs/myseafile.cert" \
 --volumes-from nginx seafile

Updates and Maintenance

The Seafile directory is stored in the permanent volume /opt/seafile. To update the base system or the seafile running options, just stop the container, update the image using docker pull sudokeys/seafile and run another container with autoconf disabled and the --volumes-from option

example :

docker run -d --name "myseafile2" \
 -p 10001:10001 -p 12001:12001 -p 8000:8000 -p 8082:8082 \
 --link mariadb:mysql-container \ 
 -e "autoconf=false" \
 --volumes-from myseafile \
 sudokeys/seafile   

To update Seafile, you should start another container with the same volume mounted but also AUTO_START disabled and then follow the normal upgrade process described in the Seafile upgrade manual.

example :

docker run -d --name "seafileUpdater" \
 -p 10001:10001 -p 12001:12001 -p 8000:8000 -p 8082:8082 \
 --link mariadb:mysql-container \ 
 -e "autoconf=false" \
 -e "AUTO_START=false" \
 --volumes-from myseafile \
 sudokeys/seafile
