Docker is an open source project to pack, ship and run any Linux application in a lighter weight, faster container than a traditional virtual machine.
Docker makes it much easier to deploy a Seafile server on your servers and keep it updated.
The base image configures Seafile with the Seafile team's recommended optimal defaults.
If you are not familiar with docker commands, please refer to docker documentation.
Note: If you want to deploy the Seafile Pro Edition with docker, refor to the Deploying Seafile-pro with Docker
To run the seafile server container:
docker run -d --name seafile \ -e SEAFILE_SERVER_HOSTNAME=seafile.example.com \ -v /opt/seafile-data:/shared \ -p 80:80 \ seafileltd/seafile:latest
Wait for a few minutes for the first time initialization, then visit
http://seafile.example.com to open Seafile Web UI.
This command will mount folder
/opt/seafile-data at the local server to the docker instance. You can find logs and other data under this folder.
More configuration Options
Custom Admin Username and Password
The default admin account is
email@example.com and the password is
asecret. You can use a different password by setting the container's environment variables:
docker run -d --name seafile \ -e SEAFILE_SERVER_HOSTNAME=seafile.example.com \ -e SEAFILE_ADMIN_EMAILfirstname.lastname@example.org \ -e SEAFILE_ADMIN_PASSWORD=a_very_secret_password \ -v /opt/seafile-data:/shared \ -p 80:80 \ seafileltd/seafile:latest
If you forget the admin password, you can add a new admin account and then go to the sysadmin panel to reset user password.
Let's encrypt SSL certificate
If you set
true, the container would request a letsencrypt-signed SSL certificate for you automatically.
docker run -d --name seafile \ -e SEAFILE_SERVER_LETSENCRYPT=true \ -e SEAFILE_SERVER_HOSTNAME=seafile.example.com \ -e SEAFILE_ADMIN_EMAILemail@example.com \ -e SEAFILE_ADMIN_PASSWORD=a_very_secret_password \ -v /opt/seafile-data:/shared \ -p 80:80 \ -p 443:443 \ seafileltd/seafile:latest
If you want to use your own SSL certificate:
- create a folder
/opt/seafile-data/ssl, and put your certificate and private key under the ssl directory.
- Assume your site name is
seafile.example.com, then your certificate must have the name
seafile.example.com.crt, and the private key must have the name
Modify Seafile Server Configurations
The config files are under
shared/seafile/conf. You can modify the configurations according to Seafile manual
After modification, you need to restart the container:
docker restart seafile
The seafile logs are under
shared/logs/seafile in the docker, or
/opt/seafile-data/logs/seafile in the server that run the docker.
The system logs are under
/opt/seafile-data/logs/var-log in the server that run the docker.
Add a new Admin
Ensure the container is running, then enter this command:
docker exec -it seafile /opt/seafile/seafile-server-latest/reset-admin.sh
Enter the username and password according to the prompts. You now have a new admin account.
Placeholder spot for shared volumes. You may elect to store certain persistent information outside of a container, in our case we keep various logfiles and upload directory outside. This allows you to rebuild containers easily without losing important information.
- /shared/db: This is the data directory for mysql server
- /shared/seafile: This is the directory for seafile server configuration and data.
- /shared/logs: This is the directory for logs.
- /shared/logs/var-log: This is the directory that would be mounted as
/var/loginside the container. For example, you can find the nginx logs in
- /shared/logs/seafile: This is the directory that would contain the log files of seafile server processes. For example, you can find seaf-server logs in
- /shared/logs/var-log: This is the directory that would be mounted as
- /shared/ssl: This is directory for certificate, which does not exist by default.
- /shared/bootstrap.conf: This file does not exist by default. You can create it by your self, and write the configuration of files similar to the
Upgrading Seafile Server
TO upgrade to latest version of seafile server:
docker pull seafileltd/seafile:latest docker rm -f seafile docker run -d --name seafile \ -e SEAFILE_SERVER_LETSENCRYPT=true \ -e SEAFILE_SERVER_HOSTNAME=seafile.example.com \ -e SEAFILE_ADMIN_EMAILfirstname.lastname@example.org \ -e SEAFILE_ADMIN_PASSWORD=a_very_secret_password \ -v /opt/seafile-data:/shared \ -p 80:80 \ -p 443:443 \ seafileltd/seafile:latest
If you are one of the early users who use the
launcher script, you should refer to upgrade from old format document.
Backup and Recovery
We assume your seafile volumns path is in
/shared. And you want to backup to
You can create a layout similar to the following in /backup directory:
/backup ---- databases/ contains database backup files ---- data/ contains backups of the data directory
The data files to be backed up:
/shared/seafile/conf # configuration files /shared/seafile/pro-data # data of es /shared/seafile/seafile-data # data of seafile /shared/seafile/seahub-data # data of seahub
- Backup the databases;
- Backup the seafile data directory;
backing up Database:
# It's recommended to backup the database to a separate file each time. Don't overwrite older database backups for at least a week. cd /backup/databases docker exec -it seafile mysqldump -uroot --opt ccnet_db > ccnet_db.sql docker exec -it seafile mysqldump -uroot --opt seafile_db > seafile_db.sql docker exec -it seafile mysqldump -uroot --opt seahub_db > seahub_db.sql
Backing up Seafile library data:
To directly copy the whole data directory
cp -R /shared/seafile /backup/data/ cd /backup/data && rm -rf ccnet
Use rsync to do incremental backup
rsync -az /shared/seafile /backup/data/ cd /backup/data && rm -rf ccnet
Restore the databases:
cp /backup/data/ccnet_db.sql /shared/ccnet_db.sql cp /backup/data/seafile_db.sql /shared/seafile_db.sql cp /backup/data/seahub_db.sql /shared/seahub_db.sql docker exec -it seafile /bin/sh -c "mysql -uroot ccnet_db < /shared/ccnet_db.sql" docker exec -it seafile /bin/sh -c "mysql -uroot seafile_db < /shared/seafile_db.sql" docker exec -it seafile /bin/sh -c "mysql -uroot seahub_db < /shared/seahub_db.sql"
Restore the seafile data:
cp -R /backup/data/* /shared/seafile/
When files are deleted, the blocks comprising those files are not immediately removed as there may be other files that reference those blocks (due to the magic of deduplication). To remove them, Seafile requires a 'garbage collection' process to be run, which detects which blocks no longer used and purges them. (NOTE: for technical reasons, the GC process does not guarantee that every single orphan block will be deleted.)
The required scripts can be found in the
/scripts folder of the docker container. To perform garbage collection, simply run
docker exec seafile /scripts/gc.sh. For the community edition, this process will stop the seafile server, but it is a relatively quick process and the seafile server will start automatically once the process has finished. The Professional supports an online garbage collection.
You can run docker commands like "docker logs" or "docker exec" to find errors.
docker logs -f seafile # or docker exec -it seafile bash
