Checkout

To install the project, you can either check it out using Git, or download a Zip file.

For checking it out from Git, run the following command:

git clone https://github.com/oat-sa/pci-training-docker.git

Note: The command above assumes you opened a terminal and changed the current directory to a parent folder. A sub-folder will be created to contain the project: pci-training-docker.

The project also comes with external tools, as Git submodules. They can be all installed at once when checking out the repository:

git clone --recurse-submodules -j8 git@github.com:oat-sa/pci-training-docker.git

Note: The command above assumes you have configured your account with SSH access. Please make sure your SSH (public) key is properly registered in your GitHub profile. In case of trouble checking out, make sure your system is also properly configured, with your SSH key created and accessible from your Git client.

These tools are optional, the stack can still work fine without them. They add convenient helpers for generating and updating PCI. For more information, please refer to the related repository.

TL; DR

Once the stack is installed, you can open TAO on your browser at https://training.pci.localhost

cd pci-training-docker
make up

Note: the commands listed below assume you opened a terminal and changed the current directory to the root of the project:

Install the stack

make

Stop the stack

make down

Start the stack

make up

Open a terminal on the server

make bash

PCI SDK

The project also comes with external tools, from the PCI SDK.

They are added as Git submodules, which can be all installed at once when checking out the repository:

git clone --recurse-submodules -j8 git@github.com:oat-sa/pci-training-docker.git

Note: The command above assumes you have configured your account with SSH access. Please make sure your SSH (public) key is properly registered in your GitHub profile. In case of trouble checking out, make sure your system is also properly configured, with your SSH key created and accessible from your Git client.

These tools are optional, the stack can still work fine without them. They add convenient helpers for generating and updating PCI. For more information, please refer to the related repository.

Submodules can still be added, if you already cloned the repository:

cd pci-training-docker
git submodule init
git submodule update

To use the PCI SDK submodule, you need to install it too:

cd pci-training-docker/sdk
npm i

Prerequisites

• Install mkcert following the official guide
• Install Docker and Docker Compose [OSX] [Ubuntu] [Windows]
• Make sure you have a minimum of 4GB RAM assigned to Docker

Installation

A make script takes care of installing everything, assuming you already have cloned the repository and have a running Docker.

make

Open TAO on your browser at https://training.pci.localhost

Update

To update the cloned repository, check out the last changes:

git fetch origin
git pull

If you also have the submodules, you may need to update them:

git submodule update

Depending on the nature of the changes, you may need either to update TAO, or reinstall all.

Update TAO

make composer-install
make tao-update

Reinstall all

Note: this will destroy and recreate the TAO instance. Be sure to backup your data before doing so.

make composer-install
make tao-install

Troubleshoot

Windows specific

On Windows be sure to modify the ROOT_FS environment variable to c:/ in the .env file:

ROOT_FS=c:/

Manual installation

• Enter package directory:

cd stack

• Open the certs folder:

cd certs

• Generate a self-signed certificate:

mkcert \
-cert-file pci.localhost-cert.pem \
-key-file pci.localhost-key.pem \
pci.localhost "*.pci.localhost"

• Install the generated self-signed certificate to your OS:

mkcert -install

• Go back to the root of the project:

cd ..

• Create pci-docker docker network:

docker network create pci-docker

• Build docker services:

docker compose up -d

• Enter TAO directory:

cd ../tao

• Install the sources:

composer install --prefer-source

• Enter package directory:

cd ../stack

• Install the platform:

docker exec -it pci-training-phpfpm php tao/scripts/taoSetup.php /var/stack/setup.json -vvv

Manual uninstallation

• Enter package directory:

cd stack

• Tear down the docker services:

docker compose down --rmi all -v

• Remove the pci-docker docker network:

docker network rm pci-docker

• Open the certs folder:

cd certs

• Uninstall the generated self-signed certificate to your OS:

mkcert -uninstall

Manual commands

• Start the server

docker compose -p pci-training -f ./stack/docker-compose.yml up -d

• Stop the server

docker compose -p pci-training -f ./stack/docker-compose.yml down

• Install TAO

docker exec -it pci-training-phpfpm composer install --prefer-source --no-interaction --no-progress
docker exec -it pci-training-phpfpm bash ./tao-cleanup.sh
docker exec -it pci-training-phpfpm php tao/scripts/taoSetup.php /var/stack/setup.json -vvv
docker exec -it pci-training-phpfpm bash ./tao-build.sh install
docker exec -it pci-training-phpfpm bash ./tao-mathjax.sh

• Update TAO

docker exec -it pci-training-phpfpm composer update --prefer-source --no-interaction --no-progress
docker exec -it pci-training-phpfpm php tao/scripts/taoUpdate.php -vvv

• Install a TAO extension

docker exec -it pci-training-phpfpm php tao/scripts/installExtension.php theTaoExtensionToInstall

• Bundle the JavaScript for a TAO extension

docker exec -it pci-training-phpfpm bash ./tao-build.sh bundle theTaoExtensionToBundle

• Bundle the CSS for a TAO extension

docker exec -it pci-training-phpfpm bash ./tao-build.sh sass theTaoExtensionToBundle

• Compile and package PCI for a TAO extension

docker exec -it pci-training-phpfpm bash ./tao-build.sh pci theTaoExtensionToBundle

docker exec -it pci-training-phpfpm bash ./tao-build.sh pci theTaoExtensionToBundle thePCIidentifier

• Open a terminal on the TAO server

docker exec -it pci-training-phpfpm bash

PCI development

The project comes configured with a development mode for the PCI. Out of the box, the following PCI are already configured:

• Geogebra
• textReaderInteraction
• audioRecordingInteraction
• likertScoreInteraction
• mathEntryInteraction

To manage this list, open the file config/taoQtiItem/debug_portable_element.conf.php, and add/remove the PCI, following this format:

<?php
return [
    ...
    'pciIdentifier' => 'path/to/pci/source/folder/',
    ...
];

Any PCI listed in this configuration will be reloaded in the authoring after each page refresh without having to bundle the PCI again.

The process is as follows:

1. Register the PCI in the debug_portable_element configuration.
2. Make a change in the source code.
3. Refresh the Item editor (you will need to re-enter the authoring mode).
4. When entering the authoring, all the source files declared in the PCI manifest are copied to the registry (make sure the manifest file lists them all).
5. The PCI in the authored item is up to date with your changes.

Note: This does not remove the need to bundle the PCI, when releasing it. This only helps not re-bundle and re-install the PCI after each change to see it in TAO.
