Local CHT Sync Setup

Before setting up CHT Sync in production, it’s very handy to be able to run it locally. This will allow you to experiment with the data flow and easily query development data quickly and locally.

These instructions assume you’re running CHT Sync, CHT Core and PostgreSQL either locally on your workstation or on a local server. They are not meant to be used to deploy a secure, always on production instance.

Setup

Copy the values in env.template file to the .env file. For more information, see the references on the Environment variables page.

Separate CouchDB instance

This setup involves starting couch2pg, PostgreSQL, pgAdmin and dbt. It assumes you have a CouchDB instance running, and you updated the .env CouchDB variables accordingly.

Run the Docker containers locally and wait for every container to be up and running:

docker compose -f docker-compose.postgres.yml -f docker-compose.yml up -d

You can verify this command worked by running docker ps. It should show 4 containers running including couch2pg, dbt, PostgreSQL, and pgAdmin.

Separate CouchDB and PostgreSQL instances

This local setup involves starting couch2pg and dbt. It assumes that CouchDB and PostgreSQL instances are run separately from the Docker Compose provided with CHT Sync, and the .env variables were updated to match those instances details.

Run the Docker containers locally and wait for every container to be up and running:

docker compose -f docker-compose.yml up -d

You can verify this command worked by running docker ps. It should show 2 containers running: couch2pg and dbt.

Cleanup

When you are done using the services, you can clean everything by running down.

For example, in the scenario of separate couchdb instance, the command should look like:

docker compose -f docker-compose.postgres.yml -f docker-compose.yml down

To remove all the data volumes, add -v at the end of this command.

Setup Superset

To build data visualization dashboards, follow the Superset instructions to run Superset and connect it to the PostgreSQL database.
