Running a docker container

Dockerized librey is a way to provide users with yet another way to self-host their own projects with a view to privacy. If you wish to help, please start by looking for bugs in used docker configurations.

Running a Docker container through ghcr

To run librey in a docker container, you can simply use the command:

docker run -d \
  --name librey \
  -e TZ="America/New_York" \
  -e CONFIG_GOOGLE_DOMAIN="com" \
  -e CONFIG_GOOGLE_LANGUAGE="en" \
  -e CONFIG_WIKIPEDIA_LANGUAGE="en" \
  -p 8080:8080 \
  ghcr.io/ahwxorg/librey:latest

Also run with watchtower for auto-updating: (optional)

docker run -d \
  --name librey-watchtower-1 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower

Running a Docker container with composer

Docker version issues

If you are going to build your own docker image based on this repository, pay attention to your Docker version, because depending on how recent the installed version is, maybe you should use the buildx command instead of build.

Docker <= 20.10: docker build

Docker > 20.10: docker buildx build

Building a docker image

If you don't want to use the image that is already available on docker hub, then you can simply build the Dockerfile directly from the github repository using the command:

docker build https://github.com/Ahwxorg/librey.git -t librey:latest

docker run -d --name librey \
    -e CONFIG_GOOGLE_DOMAIN="com" \
    -e CONFIG_GOOGLE_LANGUAGE="en" \
    -p 8080:8080 \
    librey:latest

Or, instead of doing the build remotely, you still have the opportunity to git clone the repository, and build it locally with the command:

git clone https://github.com/Ahwxorg/librey.git
cd librey/
docker build -t librey:latest .

Support for different architectures

Supported architectures for the official librey images include the same ones supported by Alpine itself, which are typically denoted as linux/386, linux/amd64, linux/arm/v6. If you need support for a different architecture, such as linux/arm/v7, you can modify the 'Dockerfile' to use a more comprehensive base image like ubuntu:latest instead.

In this case, you must run the buildx process specifying the desired architecture as shown in the example below:

docker buildx build \
    --no-cache \
    --platform linux/arm/v7 \
    --tag ahwxorg/librey:latest .

OBS: Keep in mind that this can cause some issues at build time, so you need to know a little about Dockerfiles to solve this problem for your specific case.
