EPOS Data Portal Installer

Introduction

EPOS Data Portal Installer is a user-friendly desktop application designed for the local installation of EPOS environments using Docker or Kubernetes. It simplifies the process by providing a graphical interface for the EPOS Open Source - Docker installer and EPOS Open Source - Kubernetes installer CLI tools.

Usage

1. Download the Installer:

   • Visit the latest release page to download the appropriate installer for your operating system.

   Operating System	Asset	Description
   Windows	epos-data-portal-installer-windows.exe	Windows .exe
   MacOS	epos-data-portal-installer-macos.app.zip	Application in a .app zip
   MacOS	epos-data-portal-installer-macos.pkg	Pkg installer for the application
   Linux	epos-data-portal-installer-linux	Linux executable

   Note: Some systems or browsers may flag the download due to a lack of code signing. Future releases aim to address this issue.

   Linux Users: Currently, there are challenges with creating a universal Linux binary compatible with all distributions. If you encounter issues running the binary, consider building directly from the source. For more details, see this issue.

2. Run the Installer:

   • Execute the downloaded installer to launch the application.

3. Install an Environment:

   • Click the Install button in the Home screen.

4. Select Environment Type:

   • Choose between Docker or Kubernetes as the platform to install the environment with and click Next.

5. Configure Environment:

   • Name your environment, give it a version, and click Next. (For Kubernetes, you’ll also need to select a context.)

6. Set Environment Variables:

   • Edit the environment variables as needed, or leave them at their default values if unsure, and click Next.

7. Start Installation:

   • Click the Install button to initiate the installation process.

8. View Installed Environment:

   • After the installation completes, click See in Installed Environments to view details about the newly created environment.

9. Open EPOS Data Portal:

   • In the environment details, click Open in the browser on the right of the Data Portal row to launch the EPOS Data Portal in your default browser.
   • Note: The Data Portal will work, but it will not show any data, this is because this is just a local installation of the system, it has not been populated with data yet.

10. Populate the Environment with Data:

    • To add data, return to the installer and click Populate Environment. This will open a file picker where you can select a directory containing the .ttl files to populate the catalog. For more information see EPOS-DCAT-AP

11. Refresh the Portal:

    • Once the data population is complete, refresh your browser to view the data in the EPOS Data Portal.

12. Enjoy!

About

The application is built using the Wails framework, seamlessly combining Go and Vue.js for desktop application development.

• Frontend: Vue.js with VueRouter and Vuex for routing and state management.
• Backend: Go wraps around Docker and Kubernetes CLI tools, providing a user-friendly interface.

Key Go libraries used:

• minio/selfupdate: Facilitates self-updating functionality.
• wailsapp/wails: Essential for creating the application and using the Wails Go runtime.
• mattn/go-sqlite3: Manages user-created environments.

Development

Follow the official Wails guide to set up your development environment.

Once you've set up your environment, verify it by running

wails doctor

This command checks if all necessary dependencies are installed and if the environment is correctly set up.

To run the application in development mode, navigate to the project root directory and execute:

wails dev

This command starts the application in development mode. You can make changes to the code and see the changes reflected in real-time. For more information on Wails application development, refer to the Wails documentation.

Building the Application

To build an executable for your system, run the following command:

wails build --clean

After a successful build, you'll find the system-specific executable in the build/bin directory. For more information on building an application with Wails, refer to the Wails documentation.

Contributing

If you want to contribute to a project and make it better, your help is very welcome. Contributing is also a great way to learn more about social coding on GitHub, new technologies and their ecosystems and how to make constructive, helpful bug reports, feature requests and the noblest of all contributions: a good, clean pull request.

How to make a clean pull request

Look for a project's contribution instructions. If there are any, follow them.

• Create a personal fork of the project on GitHub/GitLab.
• Clone the fork on your local machine. Your remote repo on GitHub/GitLab is called origin.
• Add the original repository as a remote called upstream.
• If you created your fork a while ago, be sure to pull upstream changes into your local repository.
• Create a new branch to work on! Branch from develop if it exists, else from master or main.
• Implement/fix your feature, comment your code.
• Follow the code style of the project, including indentation.
• If the project has tests run them!
• Write or adapt tests as needed.
• Add or change the documentation as needed.
• Squash your commits into a single commit with git's interactive rebase. Create a new branch if necessary.
• Push your branch to your fork on GitHub/GitLab, the remote origin.
• From your fork, open a pull request in the correct branch. Target the project's develop branch if there is one, else go for master or main!
• …
• If the maintainer requests further changes, just push them to your branch. The PR will be updated automatically.
• Once the pull request is approved and merged you can pull the changes from upstream to your local repo and delete your extra branch(es).

And last but not least: Always write your commit messages in the present tense. Your commit message should describe what the commit does to the code – not what you did to the code.
