If you are having trouble to get it up and running with for example openode deploy, you can test it on your local machine for further debugging.
You will need docker to build your instance, see the following link to get it:
You need to make sure that you have a Dockerfile. Please see this doc if you do not already have one.
Once you have docker and your Dockerfile, you are good to go and build it via:
docker build . -t my-app
This is building an image tagged my-app which can be used to run your application.
Using your build image (my-app) you can now run it via:
docker run -d -p 8080:80 my-app
Then you can access your site at: http://localhost:8080/.
You can also look at the logs of your application with:
docker ps | grep my-app
And using the container ID:
docker logs -f <container ID>
