Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/lychee:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture Available Tag
x86-64 ✅ amd64-\<version tag>
arm64 ✅ arm64v8-\<version tag>
armhf ❌

Application Setup

This image will not work with a prefilled /pictures mount, Lychee wants total control over this folder

Setup account via the webui, accessible at http://SERVERIP:PORT

More info at lychee.

Customization

In certain scenarios, you might need to change the default settings of Lychee. For instance, if you encounter limitations when uploading large files, you can increase this limit.

Increasing Upload Limit

The upload limit is defined in the user.ini file located in the config directory (/config). You can increase this limit by modifying the following values:

post_max_size = 500M
upload_max_filesize = 500M

After making these changes, you'll need to restart the Docker container for the changes to take effect.

Please note that these changes might have implications on your server's performance, depending on its available resources. Thus, it's recommended to modify these settings with caution.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)

Parameters

Containers are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Parameter Function
-p 80 http gui
-e PUID=1000 for UserID - see below for explanation
-e PGID=1000 for GroupID - see below for explanation
-e TZ=Etc/UTC specify a timezone to use, see this list.
-e DB_CONNECTION= DB type, from sqlite, mysql, pqsql.
-e DB_HOST= DB server hostname. For mysql and pgsql only.
-e DB_PORT= DB server port. For mysql and pgsql only.
-e DB_USERNAME= DB user. For mysql and pgsql only.
-e DB_PASSWORD= DB password. For mysql and pgsql only.
-e DB_DATABASE= Path to DB file for sqlite. DB name for mysql and pgsql.
-e APP_NAME=Lychee The gallery name.
-e APP_URL= The URL you will use to access Lychee including protocol, and port where appropriate.
-e TRUSTED_PROXIES= Set to the IP or netmask covering your reverse proxy, if running behind one. Set to * to trust all IPs (do not use * if exposed to the internet`).
-v /config Persistent config files.
-v /pictures Where lychee will store uploaded images.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

Docker Mods

Docker Mods Docker Universal Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

Via Docker Run

Image Update Notifications - Diun (Docker Image Update Notifier)

tip: We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-lychee.git
cd docker-lychee
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/lychee:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
