@ -5,6 +5,30 @@ A web api for compiling LaTeX documents in the cloud
[![Build Status](https://travis-ci.org/sharelatex/clsi-sharelatex.png?branch=master)](https://travis-ci.org/sharelatex/clsi-sharelatex)
The CLSI provide a RESTful interface to traditional LaTeX tools (or, more generally, any command line tool for composing marked-up documents into a display format such as PDF or HTML). The CLSI listens on the following ports by default:
* TCP/3009 - the RESTful interface
* TCP/3048 - reports load information
* TCP/3049 - HTTP interface to control the CLSI service
These defaults can be modified in `config/settings.defaults.coffee`.
The provided `Dockerfile` builds a docker image which has the docker command line tools installed. The configuration in `docker-compose-config.yml` mounts the docker socket, in order that the CLSI container can talk to the docker host it is running in. This allows it to spin up `sibling containers` running an image with a TeX distribution installed to perform the actual compiles.
The CLSI can be configured through the following environment variables:
* `DOCKER_RUNNER` - Set to true to use sibling containers
* `SYNCTEX_BIN_HOST_PATH` - Path to SyncTeX binary
* `COMPILES_HOST_DIR` - Working directory for LaTeX compiles
* `SQLITE_PATH` - Path to SQLite database
* `TEXLIVE_IMAGE` - The TEXLIVE docker image to use for sibling containers, e.g. `gcr.io/overleaf-ops/texlive-full:2017.1`
* `TEXLIVE_IMAGE_USER` - When using sibling containers, the user to run as in the TEXLIVE image. Defaults to `tex`
* `TEX_LIVE_IMAGE_NAME_OVERRIDE` - The name of the registry for the docker image e.g. `gcr.io/overleaf-ops`
* `FILESTORE_DOMAIN_OVERRIDE` - The url for the filestore service e.g.`http://$FILESTORE_HOST:3009`
* `STATSD_HOST` - The address of the Statsd service (used by the metrics module)
* `LISTEN_ADDRESS` - The address for the RESTful service to listen on. Set to `0.0.0.0` to listen on all network interfaces
* `SMOKE_TEST` - Whether to run smoke tests
