This is a plugin for Tutor that deploys the Hastexo Guacamole Client application alongside Open edX. Using this plugin is neccessary for running the Hastexo XBlock in your Tutor Open edX platform.

You must install a supported release of this plugin to match the Open edX and Tutor version you are deploying. If you are installing this plugin from a branch in this Git repository, you must select the appropriate one:

First of all, before installing this plugin, make sure you have installed the Hastexo XBlock to your Open edX platform running with Tutor. For that, add the XBlock to your OPENEDX_EXTRA_PIP_REQUIREMENTS in config.yml:

OPENEDX_EXTRA_PIP_REQUIREMENTS:
- git+https://github.com/hastexo/hastexo-xblock.git

rebuild the openedx docker image:

tutor images build openedx

then upload the image to the registry of your choice, and set DOCKER_IMAGE_OPENEDX in your config.yml to reference that image.

For more information about installing XBlocks, please refer to the Tutor documentation for installing XBlocks

Then, to install this plugin, run:

pip install git+https://github.com/hastexo/tutor-contrib-hastexo

To enable this plugin, run:

tutor plugins enable hastexo

Before starting Tutor, build the docker image for the hastexo service:

tutor images build hastexo

then (as with the openedx image) upload the image to your preferred registry, and set HASTEXO_DOCKER_IMAGE to point to that image.

• HASTEXO_XBLOCK_SETTINGS: The Hastexo XBlock settings, examples and details provided in the XBlock README. (default: {})
• HASTEXO_XBLOCK_VERSION: The Hastexo XBlock version. (default: stable)
• HASTEXO_GUACD_VERSION: guacd version (default: 1.5.2)
• HASTEXO_GUACD_DOCKER_IMAGE: guacd Docker image version. (default: guacamole/guacd:1.5.2)
• HASTEXO_REPLICA_COUNT: Number of replicas for the hastexo-xblock service. (default: 1)
• HASTEXO_ENABLE_SUSPENDER: If True, run 1 pod in the hastexo-xblock-suspender deployment. If False, run 0 pods, effectively disabling the deployment. (Default: True).
• HASTEXO_ENABLE_REAPER: If True, run 1 pod in the hastexo-xblock-reaper deployment. If False, run 0 pods, effectively disabling the deployment. (Default: True).

When using the terminal_font_name setting via HASTEXO_XBLOCK_SETTINGS, the requested font must be installed in the guacd container. This means that you'll need to build a custom guacd image. For that:

• Define the HASTEXO_GUACD_DOCKER_IMAGE in your config.yml to override using the default upstream image.
• Create a YAML plugin to patch hastexo-guacd-dockerfile and add your font installation steps. For example:

  name: guacdfonts
  version: 1.0.0
  patches:
    hastexo-guacd-dockerfile: |
      USER root
      RUN apt update && apt install -y fonts-hack-ttf
  

• Enable the YAML plugin and save your configuration changes (tutor config save)
• Build the custom docker image for guacd:

  tutor images build guacd
