Initial setup

Pre-requisites

In order to build and run locally, you will need the following utilities:

• node v14
• bash
• jq
• make
• pip3
• yarn
• docker
• docker-compose

Extra Windows pre-requisites

This guide is for running the project using WSL2 in Windows.

1. Follow this guide https://docs.microsoft.com/en-us/windows/wsl/setup/environment#get-started

   This includes:

   • Docker for desktop - with WSL2 integration
   • WSL2

2. Create your own user

   We want to avoid using root, it can create unexpected behavior.

   1. Start by creating your user, adding it to sudo group and change to that user

      adduser <user-name>
      usermod -aG sudo <user-name>
      su <user-name>
      

   2. Now the user is created, and you are logged into that user. To set this as a default user, you can add/edit the file /etc/wsl.conf to:

      [user]
      default=<use-name>
      

You're now set to continue with Running, below there's additional notes to consider:

Database permission

Ensure that auth/pg/pgdata/ and bifrost/bifrost_db/data/ are owned by <user-name>.

Project placement

You have to store the project, i.e. clone the repo, to the WSL2 filesystem and NOT the Windows filesystem. The Windows filesystem is emulated and the user permission file causes unexpected behavior.

E.g. clone the repo to /home/<user-name>/git/. This is placed in the git directory within your linux users home directory.

Be sure to get submodules git submodule update --init --recursive

Host file

Latter in this README.md you will have to add something to your host file, this must be added in both the WSL2 hosts file and the Windows hosts file.

• task (Used for running tests)

Running

On the first run, you'll need to install the dependencies for the web app:

pushd ./app && yarn install && popd

When running locally, you need a correctly figured .env file. (this includes generating or in another way getting the necessary .crt and .pem files)

Start by copying the .env.local.example file and make any adjustments you need.

Of particular importance is the SOFI_HOSTNAME and SOFI_PORT, as well as the TLS_CERT_PATH and TLS_KEY_PATH.

Regarding the TLS_CERT and TLS_KEY, it is important that the certificate be a ‘real’ certificate signed by a trusted CA. You can use Let’s Encrypt for this purpose.

The SOFI_HOSTNAME must match your certificate.

To run locally using docker-compose, execute:

make run

This will launch all containers with locally mounted files, enabling automatic code reload, as well as hot-module-reload (HMR) in the browser.

By default, services will be available on https://dev.sofi-platform.dk. This can be changed by modifying the generated .env file. The relevant env variables are SOFI_SCHEME, SOFI_HOSTNAME, and SOFI_PORT.

Make sure to edit your /etc/hosts file (c:\windows\system32\drivers\etc\hosts on Windows) and include the line:

127.0.0.1	dev.sofi-platform.dk
127.0.0.1	dev2.sofi-platform.dk

Setting SOFI_HOSTNAME to localhost or 127.0.0.1 is not currently supported.

When running in the dev environment, you can create a default set of demo users that can sign-in to the application.

Do so by running after the application has been started.

auth/config/keycloak/create-users.sh

Username: admin@fvst.dk Password: Delegate21!

You can access keycloak admin interface through https://{hostname}/auth/admin Username: admin Password: admin

Local dev running

Create virtual env, install dependencies

$ python -m venv .venv
$ . .venv/bin/activate
$ pip install -r requirements.txt

Have a mongodb instance running on localhost:27017

$ sh start_local.sh

On windows, in venv with dependencies installed

set FLASK_APP=wsgi.py
set FLASK_DEBUG=1
set APP_CONFIG_FILE=config.py
set FLASK_RUN_HOST=127.0.0.1
set FLASK_RUN_PORT=8080
flask run

Default user username: test password: test from seed_data project

Generating simulated data

When running locally, the bifrost db gets pre-seeded with the contents of the .jsonl files inside initdb.d.

These .jsonl files can be regenerated based on the latest specification running:

rm bifrost/bifrost_db/initdb.d/generated.jsonl
./generate_dummy_data.sh

The seeding only occurs when the database is first created, so to force the change to take effect, run:

make clean && make run
