## About
* [Docker](https://docker.com/) 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](https://github.com/haiwen/seafile) 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](https://docs.docker.com/engine/reference/commandline/cli/).
**Note**: If you want to deploy the Seafile Pro Edition with docker, refor to the [Deploying Seafile-pro with Docker](../deploy_pro/deploy_with_docker.md)
## For seafile 7.x.x
Starting with 7.0, we have adjusted seafile-docker image to use multiple containers. The old image runs MariaDB-Server and Memcached in the same container with Seafile server. Now, we strip the MariaDB-Server and Memcached services from the Seafile image and run them in their respective containers.
If you plan to deploy seafile 7.0, you should refer to the [Deploy Documentation](<../docker/deploy seafile with docker.md>).
If you plan to upgrade 6.3 to 7.0, you can refer to the [Upgrade Documentation](<../docker/6.3 upgrade to 7.0.md>).
## For seafile 6.x.x
### Getting started
To run the seafile server container:
```sh
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 `me@example.com` and the password is `asecret`. You can use a different password by setting the container's environment variables:
e.g.
```sh
docker run -d --name seafile \
-e SEAFILE_SERVER_HOSTNAME=seafile.example.com \
-e SEAFILE_ADMIN_EMAIL=me@example.com \
-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 `SEAFILE_SERVER_LETSENCRYPT` to `true`, the container would request a letsencrypt-signed SSL certificate for you automatically.
e.g.
```
docker run -d --name seafile \
-e SEAFILE_SERVER_LETSENCRYPT=true \
-e SEAFILE_SERVER_HOSTNAME=seafile.example.com \
-e SEAFILE_ADMIN_EMAIL=me@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 `seafile.example.com.key`.
#### Modify seafile server configurations
The config files are under `shared/seafile/conf`. You can modify the configurations according to[ Seafile manual](https://download.seafile.com/published/seafile-manual/home.md)
After modification, you need to restart the container:
```
docker restart seafile
```
#### Find logs
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 `shared/logs/var-log`, or `/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.
### Directory structure
#### `/shared`
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/log` inside the container. For example, you can find the nginx logs in `shared/logs/var-log/nginx/`.
* /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/seafile/seafile.log`.
* /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 `samples` folder.
### Upgrading seafile server
If you plan to upgrade 6.3 to 7.0, you can refer to the [Upgrade Documentation](<../docker/6.3 upgrade to 7.0.md>).
To upgrade to the latest version of seafile 6.3:
```sh
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_EMAIL=me@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 are one of the early users who use the `launcher` script, you should refer to [upgrade from old format](https://github.com/haiwen/seafile-docker/blob/master/upgrade_from_old_format.md) document.
### Backup and recovery
#### Struct
We assume your seafile volumns path is in `/shared`. And you want to backup to `/backup` directory.
You can create a layout similar to the following in /backup directory:
```struct
/backup
---- databases/ contains database backup files
---- data/ contains backups of the data directory
```
The data files to be backed up:
```struct
/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
Steps:
1. Backup the databases;
2. Backup the seafile data directory;
[Backup Order: Database First or Data Directory First](../maintain/backup_recovery.md)
* backing up Database:
```bash
# 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
```bash
cp -R /shared/seafile /backup/data/
cd /backup/data && rm -rf ccnet
```
* Use rsync to do incremental backup
```bash
rsync -az /shared/seafile /backup/data/
cd /backup/data && rm -rf ccnet
```
### Recovery
* Restore the databases:
```bash
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:
```bash
cp -R /backup/data/* /shared/seafile/
```
### Garbage collection
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](../maintain/seafile_gc.md)' 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.
### Troubleshooting
You can run docker commands like "docker exec" to find errors.
```sh
docker exec -it seafile bash
```
