hydrus-server-docker 
hydrus server running on Debian
This is a simple Debian-based Docker setup for running hydrus server from source.
The latest build runs hydrus server version 379.
Table of contents
Install
The easiest way to install is via Docker Hub:
user@local:~$ docker pull mserajnik/hydrus-server-docker
By default, this will pull the latest build. To specify an image with a specific version of hydrus server, provide the version number as tag, e.g.:
user@local:~$ docker pull mserajnik/hydrus-server-docker:379
See here for all the available version numbers/tags.
Alternatively, you can clone this repository and build the image yourself:
user@local:~$ git clone --recurse-submodules https://github.com/mserajnik/hydrus-server-docker.git
user@local:~$ cd hydrus-server-docker
user@local:hydrus-server-docker$ docker build . -t hydrus-server-docker
Dependencies
Updating
If you have installed via Docker Hub, just pull the updated image. Otherwise, pull from this repository and make a new build.
This repository follows semantic versioning and any
breaking changes that require additional attention will be released under a new
major version (e.g., 2.0.0). Minor version updates (e.g., 1.1.0 or 1.2.0)
are therefore always safe to simply install via the routine mentioned before.
When necessary, this section will be expanded with upgrade guides to new major versions.
Upgrading from 2.x to 3.x
Upgrading from 2.x to 3.x can be done via pulling the updated image from
Docker Hub or building it yourself and requires no further manual changes.
Due to the introduction of OpenCV to hydrus server (which is hard to build on Alpine), the Docker image is now based on Debian instead of Alpine instead.
Upgrading from 1.x to 2.x
Upgrading from 1.x to 2.x can be done via pulling the updated image from
Docker Hub or building it yourself and requires no further manual changes.
Since there have been issues with running the pre-compiled version of hydrus
server 335+ (which made the switch to Python 3) on the previous Docker setup,
starting with 2.0.0, the Docker image is now based on Alpine (instead of
Debian) and runs hydrus server from source.
This approximately halves the resulting image size while at the same time making it easier to adapt for future changes/dependencies.
Usage
Ports
First, you need to bind the exposed ports. This can be done automatically
using -P but it is recommended to bind them manually instead since having
changing ports every time you run a new container might be annoying when used
in combination with other services.
hydrus-server-docker exposes the following three ports by default:
45870/tcp45871/tcp45872/tcp
These are used to access the different services. 45870 is the default port
for the server administration service while 45871 and 45872 are used for
repositories. You will generally have two (one for tags and one for files), but
if you add more, you will also need to expose additional ports.
Storage
Per default, hydrus-server-docker stores its databases and media inside the
/data directory which is a mount point that is persisted as a volume. A new
volume will be created every time a container is created, making it less ideal
as a long-term solution. Instead, you should create a named volume yourself and
mount that over it:
user@local:~$ docker volume create hydrus-server-data
UID/GID
The user that owns the data and runs the server inside the container has the
UID 1000 and the GID 1000 by default. You can change these by providing the
environment variables CUSTOM_UID and CUSTOM_GID when creating a container.
This is useful if you want to access the data outside the container with a user
with different IDs without hassle. In such a case, CUSTOM_UID and
CUSTOM_GID should match the user that is going to access the data on the
host.
Here is a full example for running the container with all the options mentioned above:
user@local:~$ docker run -p 45870:45870 -p 45871:45871 -p 45872:45872 -v hydrus-server-data:/data -e CUSTOM_UID=1000 -e CUSTOM_GID=1000 -d mserajnik/hydrus-server-docker
Specifying the same named volume every time a container is created gives each of these instances access to the same persisted data.
Of course, using a bind mount instead of a named volume is also possible but for performance reasons only recommended if you need easy access to the data on the host machine.
