|
|
## Features
|
|
- Complete redesign of the [official Docker deployment](https://manual.seafile.com/docker/deploy%20seafile%20with%20docker/) with containerization best-practices in mind.
|
|
- Runs seahub (frontend) and seafile server (backend) in separate containers, which commuicate with each other over TCP.
|
|
- Cluster without pro edition.
|
|
- Completely removed Nginx and self-implemented Let's Encrypt and replaced it with two caddy services.
|
|
- Increased Security:
|
|
- The caddy reverse proxy serves as a single entry point to the stack. Everything else runs in an isolated network.
|
|
- Using [Alpine Linux](https://alpinelinux.org/about/) based images for the frontend, which is designed with security in mind and comes with proactive security features.
|
|
- Official Seafile Docker deployment uses entirely outdated base images and dependencies. Here base images and dependencies are updated on a regular basis.
|
|
- Reworked Dockerfiles featuring multi-stage builds, allowing for smaller images and faster builds.
|
|
- Schedule offline garbage collection with cron job.
|
|
- Runs upgrade scripts automatically when a new image version is deployed.
|
|
- All features of Seafile Community Edition are included.
|
|
|
|
## Structure
|
|
|
|
Services:
|
|
- *seafile-server*
|
|
- contains the backend component called [seafile-server](https://github.com/haiwen/seafile-server)
|
|
- handles storage, some direct client access and seafdav
|
|
- *seahub*
|
|
- dynamic frontend component called [seahub](https://github.com/haiwen/seahub)
|
|
- serves the web-ui
|
|
- communicates with seafile-server
|
|
- *seahub-media*
|
|
- serves static website content as well as avatars and custom logos
|
|
- *db*
|
|
- the database used by *seafile-server* and *seahub*
|
|
- *memcached*
|
|
- database cache for *seahub*
|
|
- *seafile-caddy*
|
|
- reverse proxy that forwards paths to the correct endpoints: *seafile-server*, *seahub* or *seahub-media*
|
|
- is the single external entrypoint to the deployment
|
|
|
|
Volumes:
|
|
|
|
- *seafile-data*
|
|
- shared data volume of *seafile-server* and *seahub*
|
|
- also contains configuration and log files
|
|
- *seafile-mariadb*
|
|
- volume of the *db* service
|
|
- stores the database
|
|
- *seahub-custom*
|
|
- contains custom logos
|
|
- stored by *seahub* and served by *seahub-media*
|
|
- *seahub-avatars*
|
|
- contains user avatars
|
|
- stored by *seahub* and served by *seahub-media*
|
|
|
|
*Note: In the official docker deployment custom and avatars are served by nginx. Seahub alone is not able to serve them for some reason, hence the separate volumes.*
|
|
|
|
Networks:
|
|
- *seafile-net*
|
|
- isolated local network used by the services to communicate with each other
|
|
|
|
## Getting Started
|
|
|
|
1. ***Prerequisites***
|
|
|
|
Requires Docker and docker-compose to be installed.
|
|
|
|
2. ***Get the compose file***
|
|
|
|
#### Docker Compose
|
|
|
|
Use this compose file as a starting point.
|
|
```
|
|
wget https://raw.githubusercontent.com/ggogel/seafile-containerized/master/compose/docker-compose.yml
|
|
```
|
|
|
|
_Note:_ We expect certain services names. Do not rename services except `db`.
|
|
|
|
#### Docker Swarm
|
|
|
|
If you run a single node swarm and don't want to run multiple replicas, you can use the same compose file. Otherwise refer to [Additional Information / Docker Swarm](#Docker-Swarm-1).
|
|
|
|
|
|
3. ***Set environment variables***
|
|
|
|
**Important:** The environment variables are only relevant for the first deployment. Existing configuration in the volumes is **not** overwritten.
|
|
|
|
On a first deployment you need to carefully set those values. Changing them later can be tricky. Refer to the Seafile documentation on how to change configuration values.
|
|
|
|
### *seafile-server*
|
|
The name of the mariadb service, which is automatically the docker-internal hostname.
|
|
```
|
|
- DB_HOST=db
|
|
```
|
|
Password of the mariadb root user. This must equal MYSQL_ROOT_PASSWORD.
|
|
```
|
|
- DB_ROOT_PASSWD=db_dev
|
|
```
|
|
Time zone used by Seafile.
|
|
```
|
|
- TIME_ZONE=Europe/Berlin
|
|
```
|
|
|
|
This will be used for the SERVICE_URL and FILE_SERVER_ROOT.
|
|
Important: Changing those values in the config files later won't have any effect because they are written to the database. Those values have priority over the config files. To change them enter the "System Admin" section on the web-ui. If you encounter issues with file upload, it's likely that those are configured incorrectly.
|
|
```
|
|
- SEAFILE_SERVER_HOSTNAME=seafile.mydomain.com
|
|
```
|
|
If you plan to use a reverse proxy with https, set this to true. This will replace http with https in the SERVICE_URL and FILE_SERVER_ROOT.
|
|
```
|
|
- HTTPS=false
|
|
```
|
|
|
|
### *seahub*
|
|
Username / E-Mail of the first admin user.
|
|
```
|
|
- SEAFILE_ADMIN_EMAIL=me@example.com
|
|
```
|
|
Password of the first admin user.
|
|
```
|
|
- SEAFILE_ADMIN_PASSWORD=asecret
|
|
```
|
|
|
|
### *db*
|
|
Password of the mariadb root user. Must match DB_ROOT_PASSWD.
|
|
```
|
|
- MYSQL_ROOT_PASSWORD=db_dev
|
|
```
|
|
Enable logging console.
|
|
```
|
|
- MYSQL_LOG_CONSOLE=true
|
|
```
|
|
|
|
4. ***(Optional) Migrating volumes from official Docker deployment or native install***
|
|
|
|
**If you set up Seafile from scratch you can skip this part.**
|
|
|
|
This deployment uses [named volumes](https://docs.docker.com/storage/volumes/), which come with several advantages over bind mounts, used in the official Seafile Docker deployment. They are the recommended mechanism for persisted storage on Docker.
|
|
|
|
The default path for named volumes on Docker is `/var/lib/docker/volumes/PROJECT-NAME_VOLUME-NAME/_data`.
|
|
|
|
To migrate storage from the official Docker deployment or native (non-Docker) deployment run:
|
|
```
|
|
mkdir -p /var/lib/docker/volumes/seafile_seafile-data/_data
|
|
mkdir -p /var/lib/docker/volumes/seafile_seafile-mariadb/_data
|
|
mkdir -p /var/lib/docker/volumes/seafile_seahub-custom/_data
|
|
mkdir -p /var/lib/docker/volumes/seafile_seahub-avatars/_data
|
|
|
|
cp -r /opt/seafile-data /var/lib/docker/volumes/seafile_seafile-data/_data
|
|
cp -r /opt/seafile-mysql/db /var/lib/docker/volumes/seafile_seafile-mariadb/_data
|
|
mv /var/lib/docker/volumes/seafile_seafile-data/_data/seafile/seahub-data/custom /var/lib/docker/volumes/seafile_seahub-custom/_data
|
|
mv /var/lib/docker/volumes/seafile_seafile-data/_data/seafile/seahub-data/avatars /var/lib/docker/volumes/seafile_seahub-avatars/_data
|
|
```
|
|
|
|
If you are migration from a native (non-Docker) deployment, you additonaly need to change the ownership of the folders:
|
|
```
|
|
chown -R root:root /var/lib/docker/volumes/seafile_seafile-data
|
|
chown -R root:root /var/lib/docker/volumes/seafile_seafile-mariadb
|
|
chown -R root:root /var/lib/docker/volumes/seafile_seahub-custom
|
|
chown -R root:root /var/lib/docker/volumes/seafile_seahub-avatars
|
|
```
|
|
|
|
5. ***(Optional) Reverse Proxy***
|
|
|
|
The caddy reverse proxy integrated with the deployment exposes **port 80**. Point your existing reverse proxy to that port.
|
|
|
|
This deployment does by design **not** include a reverse proxy capable of HTTPS and Let's Encrypt, unlike the official deployment, because usually Docker users already have some docker-based reverse proxy solution deployed, which does exactly that.
|
|
|
|
6. ***Deployment***
|
|
|
|
#### Docker Compose
|
|
After you followed the above steps and you have configured everything correctly run:
|
|
```
|
|
docker-compose -p seafile up -d
|
|
```
|
|
#### Docker Swarm
|
|
After you followed the above steps and you have configured everything correctly run:
|
|
```
|
|
docker stack deploy -c docker-compose.yml seafile
|
|
```
|
|
