Introduction

If you want to run the entire GTN material website locally or test your new training material you can do this!

Currently, the website is generated from the metadata and the tutorials using Jekyll, a simple static site builder. We can use Jekyll to run a server to check if the tutorial is correctly added and rendered.

Agenda

In this tutorial, you will learn how to run a local instance of the GTN website:

1. Introduction
2. Installation of the requirements
3. Checking the website generation
4. Stopping the server
5. Conclusion

Installation of the requirements

The first step is to install the needed tools inside a conda environment. A conda environment is a directory that contains a specific collection of packages. For example here to run the website, we need ruby, pandas, requests, etc. By creating a conda environment and installing the needed tools there, we do not affect your main installation.

This step has to be done once.

We also need to make sure that a couple of other utilities and build requirements are present: git, curl & make. The easiest way to install these is with your package manager of choice - i.e. yum, apt, brew etc.

Hands-on: Install the requirements

1. Open a Terminal

2. Use your package manager to install git, curl and make

   • For Debian/Ubuntu: sudo apt update && sudo apt install git curl make
   • For Fedora/CentOs/RedHat: sudo yum install git curl make
3. (If not done yet) Clone the training material GitHub repository: git clone https://github.com/galaxyproject/training-material.git
4. Navigate to the training-material/ folder with cd

5. Set up the conda environment

   It will install some needed tools (ruby, nodejs, etc) in a protected environment, without interfering with the existing tools or versions.

   1. Install conda (if not already installed): make install-conda
   2. (You may need to exit the terminal and re-open for conda to be recognised. Navigate back to the same place.)
   3. Create the galaxy_training_material conda environment: make create-env
6. Install Jekyll and related modules into the conda environment: make install

Details: Troubleshooting `libxml2` errors

If you encounter an error about libxml2 on Linux, please try to install libxml2-dev (executing sudo apt install libxml2-dev) if on Debian/Ubuntu or libxml2-devel (executing sudo yum install libxml2-devel) if on Fedora/RedHat/CentOS, and re-run make install .

Checking the website generation

Once Jekyll and its modules are installed in our conda environment, we can check the generation of the website locally:

Hands-on: Checking the website generation locally

1. Run a local Jekyll server with make serve-quick
2. Visualize at http://localhost:4000/training-material/
3. Edit one of the tutorials:
   • For example, open topics/introduction/tutorials/galaxy-intro-peaks2genes/tutorial.md in a text editor of your choice.
   • Make some changes to the Introduction paragraph, and save the file.
   • Refresh the tutorial page in your browser until you can see the changes you made.
     • this may take a little bit of time; in the terminal you can monitor when the regeneration is complete

With make serve-quick, a local Jekyll server will run in background. It will check the changes and regenerate the website accordingly. You may need to reload the page to see the changes (and sometimes to wait 1-2 minutes).

Tip: Tips

1. Use make serve instead of make serve-quick to get all plugins, but also configure the post, host and pass additional flags. This however can be quite slow.

2. Need to speed up the cloning step? You coud fetch only the latest commit of the main branch:

   $ git clone https://github.com/galaxyproject/training-material.git --depth 1 --branch main
   

3. Running on a VM or remote machine?

   If you are not running this on your local machine, but e.g. on a VM, you may need to configure a webserver to serve the website.

   Below is an example NGINX configuration (e.g. in /etc/nginx/sites-enabled/default)

   location /training-material/ {
     root /home/ubuntu/training-material/_site/;
   }
   

   Change the root path above to wherever you cloned the training material folder

Stopping the server

Once you are done, you can stop the server and clean your repository.

Hands-on: Stopping the server

1. Stop the server with CTRL-C
2. Clean the repository: make clean

Conclusion

Key points

• Checking the generated website can be done locally
