Postgresql service

Installation

# install node modules
$ npm install

Environment variables

In order to run the code, some environment variables are needed. They are specified in the template.env file at the root of the project.

For a local deployment:

1. cp template.env .env
2. Edit .env according to the chosen configuration

The values will be read from the file by default, but you can override any of those by exporting manually the variable before launching the service.

Running the app without docker

You will need to provide a healthy connection to a database in order for the service to start.

# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod

Running the app with docker

# build
$ docker-compose build

# deploy
$ docker-compose up [-d]

# build and deploy
$ docker-compose up --build [-d]

Migrations

Migrations are done automaticaly the docker image on startup. You can run it manualy:

MIGRATING=1 npm run migrate:run

ATTENTION when migrating, tables belong to postgres, not to "user", you need to grant "user" the access to the tables.

docker-compose exec  database-postgres psql --user postgres --password services
# Give the "POSTGRES_ADMIN_PASSWORD" password
GRANT ALL ON ALL TABLES IN SCHEMA public TO "user";

Replace "user" by the database user given in .env file.

Test

Be carefull, end to end tests drop all data from you tables :

# create a venv
python3 -m venv venv
. bin/activate

# Install dependencies
pip install -r tests/requirements.txt

# Run end to end tests
pytest

#FIXME: running tests destroys migration table, you can't apply migrations after this

Setup

Start the DATABASE, and use psql to setup database user "user" (or whatever name you gave it) rights :

psql --user postgres services
# giv postgres password
GRANT ALL ON DATABASE services TO "user";
GRANT ALL ON ALL TABLES IN SCHEMA public TO "user";
GRANT ALL ON ALL SEQUENCES IN SCHEMA "public" TO "user";
