Helioviewer Docker

This repo provides a containerized development environment for working with Helioviewer

Usage

To run the dev environment, install Docker

Once installed clone this repo and run docker compose:

git clone --recurse-submodules https://github.com/Helioviewer-Project/helioviewer.org-docker.git
cd helioviewer.org-docker
mv .env.example .env
docker compose up -d --wait

It may take a while for the containers to be built and the application to start up. Once the output from docker settles down, check that it's running by going to http://localhost:8080/

Configuration

Configuration is made via the .env file. By default this is set to bind and run everything on localhost. You can change this by editing .env

Testing

For contributors to this environment, you can write tests to verify that the Helioviewer environment is working. The tests folder contains scripts that test a particular feature of Helioviewer.

After creating a test, add it to the Test Helioviewer environment step in `.github/workflows/build-check.yaml

Debugging

The container has xdebug configured for debugging. If you have xdebug listening on port 9003 (the default xdebug port), then php code running in the container will trigger debug requests.

Client configuration may vary.

VSCode

For vscode, install the PHP Debug extension provided by xdebug and use the following configuration:

{
    "name": "Listen for Xdebug",
    "type": "php",
    "request": "launch",
    "port": 9003,
    "pathMappings": {
        "/var/www/api.helioviewer.org": "${workspaceFolder}"
    }
}

Troubleshooting

If the helioviewer isn't loading for you, here are the first things to check.

Submodules

The helioviewer.org repository relies on some submodules. Make sure to run git submodule update --init --recursive --remote in the helioviewer.org repository. If you cloned this repo with --recurse-submodules then this likely isn't the problem.

Bad configuration

On a clean setup, the container installs its own Config.ini and Private.php in api/settings, and Config.js in helioviewer.org/resources/js/Utility.

Double check these files if you're getting strange errors. Config.js should point to localhost:8080/8081 and not *helioviwer.org.

Services not running

There are 5 primary containers that make up this environment

• redis
• mariadb
• API server
• Web Server
• Movie Builder

There is also a "CLI" container, which doesn't provide any direct service, but is useful for development purposes like downloading test data or accessing application data.

If any of the primary containers aren't running properly, this could be the source of some issues.

XDebug Ports

If anything is listening on port 9003 besides xdebug, it can interfere with the xdebug extension running in the container.

The Jupyter extensions by microsoft use port 9003 when you are working with a python notebook in vscode. This will interfere with the xdebug extension in the container, and it will seem like the webserver has hung.

If everything seems like it should be working, but requests are hanging for no apparent reason, check if you have a running process listening on port 9003.
