NOTE: Make sure you have already cloned original emba repository in the emba directory

NOTE: If you are using docker desktop on a Mac or windows machine. Remove line network_mode: host from docker-compose.yml

NOTE: If you are using docker desktop windows machine. The database host inside env would be host.docker.internal

NOTE: For now our compose file is compatible with docker-compose version 1.27.x. 1.28.x and 1.29.x are already available and by default you will end up with latest version unless you specify explicitly while installing. Please install version1.27.x untill we fix this

Initial Setup

  1. Change directory to root of the repository i.e amos-ss2021-emba-service
  2. Clone original emba repository (git clone https://github.com/e-m-b-a/emba.git)
  3. Run ./emba/installer.sh -F to force install all the dependencies on host. This enables functionalities like CVE Search.
  4. Setup docker containers(See below)

Updating environment variables

Refer to template.env, you will see the following env variables

1. DATABASE_NAME: Name of the sql database
2. DATABASE_USER: User of the database
3. DATABASE_PASSWORD: For for logging in to the database
4. DATABASE_HOST: host of the database
5. DATABASE_PORT: port
6. MYSQL_ROOT_PASSWORD: Root password. Always equal to DATABASE_PASSWORD for our dev setups

We are not maintaining a central copy for now. Till then please main your own copy wherever you setup your dev environment.

Building and running containers

  1. Build your image
    docker-compose build

  2. Before bringing your containers up rename template.env -> .env and edit .env file should to look like:

DATABASE_NAME=<Name you are going to give your db>
DATABASE_USER=root
DATABASE_PASSWORD=<value of MYSQL_ROOT_PASSWORD>
DATABASE_HOST=0.0.0.0(or host.docker.internal for windows)
DATABASE_PORT=3306
MYSQL_ROOT_PASSWORD=<This should be set>

  1. Bring your containers up
    docker-compose up -d

  2. Now you can exec into the mysql container and create your database.

docker exec -it amos-ss2021-emba-service_auth-db_1 bash
mysql -p

When prompted for a password enter the value in MYSQL_ROOT_PASSWORD
Create database <value in DATABASE_NAME>

  1. Restart your containers. This additional step is neccessary since there is no dependency between the containers. And django would try to connect to DB not there yet and fail.
    docker-compose restart emba

  2. Exec into your emba-django container
    docker exec -it amos-ss2021-emba-service_emba_1 bash

  3. Run migrations

python3 manage.py makemigrations uploader users
python3 manage.py migrate

Testing Django setup

Test if django application (uWSGI workers) came up
curl -XGET 'http://0.0.0.0:8000'
You should get a response like this:

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <h1>EMBArk home!</h1>
</body>

Updating code

Whenever you change any code in embark(django project). You will have to make it live. Since all our code is mounted through compose. Developers just need to run the following command -
docker-compose restart emba

Exec inside the containers

If you want to run something from inside the container like a shell script to analyze some firmware

  1. Paste that firmware inside directory embark
  2. Exec(Enter) into your container with docker exec -it amos-ss2021-emba-service_emba_1 bash
  3. Run your script.
