Installation

Detailed installation instructions can be found in the Overleaf Toolkit. To run a custom image, add a file named docker-compose.override.yml with the following or similar content into the overleaf-toolkit/config directory:

---
services:
    sharelatex:
        image: sharelatex/sharelatex:ext-ce

If you want to build a Docker image of the extended CE based on the upstream v5.5.0 codebase, you can check out the corresponding tag by running:

git checkout v5.5.0-ext-v3

After building the image, switch to the latest state of the repository and check the server-ce/hotfix directory. If a subdirectory matching your version (e.g., 5.5.1) exists, build a patched image. Alternatively, you can download a prebuilt image from Docker Hub:

docker pull overleafcep/sharelatex:5.5.0-ext-v3

Make sure to update the image name in overleaf-toolkit/config/docker-compose.override.yml accordingly.
