For ES.DOCUMENTS configuration, you will find multiple other configurations below it. Each has default values that you can override using the environment variables

Setup your Elasticsearch instance and ensure that it is up and running.

1. Follow Configuration section to update config values, like database, etc ..
2. Goto UBahn-api, run npm i and npm run lint
3. Import mock data, node scripts/db/genData.js, this will gen some data for test (if you need this)
4. Startup server node app.js or npm run start

You can use the scripts npm run insert-data (and npm run delete-data) to insert mock data (and delete mock data respectively). The data is inserted into Postgres and Elasticsearch. You need to setup the configurations beforehand and also start the elasticsearch instance before you run these scripts. You can run the script npm run migrate-db-to-es to dump data in db into es.

Make sure all config values are right, and you can run on local successfully, then run below commands

1. Navigate to the directory docker

2. Rename the file sample.env to .env

3. Set the required AUTH0 configurations, DB configurations and ElasticSearch host in the file .env

4. Once that is done, run the following command

   docker-compose up

5. When you are running the application for the first time, It will take some time initially to download the image and install the dependencies
