Dockerized Epsilon Playground

NOTE: This repository is now deprecated, as it has been replaced by the standalone server in this project:

https://github.com/epsilonlabs/playground-backend

This is a dockerized version of the Epsilon Playground.

Fetch and Run the Docker Hub Image

Use this command to fetch the latest version of the Epsilon Playground image from Docker Hub and run it in a container:

docker run -p 8000:80 eclipseepsilon/playground:latest

Build and Run the Docker Image

If you prefer to build the image from source instead of fetching it from Docker Hub, clone the repository and use this command to build the image:

docker image build -t playground:latest .

and this command to run the image in a container:

docker run -p 8000:80 playground:latest

Should you need to customise the port that nginx runs on, you can do so through the PORT environment variable (as required by Google Cloud Build):

docker run --env PORT=8020 -p 8000:8020 playground:latest

Access the Epsilon Playground

Once the container is up, go to http://localhost:8000 in your browser to access the playground's web interface.

Run the Docker Image with your Own Examples

The dockerized version of the playground comes with the same set of examples as the online version. To start an instance with your own examples on the left hand side, use the following command, replacing <examples-folder-absolute-path> with the absolute path of your examples folder.

docker run -p 8000:80 -v <examples-folder-absolute-path>:/etc/nginx/html/examples playground:latest

Your examples folder should contain an examples.json file with at least one example. A sample examples folder with a single example is provided in this repository and more examples are available in the examples folder of Epsilon's website repository.

Replace the Playground Front-End

If you would like to use only the backend services and replace the front-end altogether, you can start an instance using the following command, replacing <front-end-folder-absolute-path> with the absolute path of your custom front-end folder.

docker run -p 8000:80 -v <front-end-folder-absolute-path>:/etc/nginx/html playground:latest

Your front-end folder should contain an index.html file. A minimal alternative front-end that you can use as a starting point for developing your custom front-end is available in the miniground folder of this repository.

Publish to Docker Hub

Run the following command to build a linux/amd64 image (replace x.y.z with the actual version you wish to release)

docker buildx build --no-cache --platform linux/amd64 -t eclipseepsilon/playground:x.y.z .
docker tag eclipseepsilon/playground:x.y.z eclipseepsilon/playground:latest

And then push it to Docker Hub

docker push eclipseepsilon/playground:x.y.z
docker push eclipseepsilon/playground:latest
