Build EMBArk

Michael Messner edited this page Aug 21, 2021 · 18 revisions

Initial Setup

  1. Clone embark github repository i.e git clone [email protected]:e-m-b-a/embark.git
  2. Change directory to root of the repository i.e embark
  3. Clone original emba repository (git clone https://github.com/e-m-b-a/emba.git)
  4. Run cd emba && sudo ./installer.sh -F to force install all the dependencies on your host. This enables functionalities like CVE Search.
  5. Setup docker environment (see below)

Updating environment configuration

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

DATABASE_NAME: Name of the sql database
DATABASE_USER: User of the database
DATABASE_PASSWORD: For for logging in to the database
DATABASE_HOST: host of the database
DATABASE_PORT: port
MYSQL_ROOT_PASSWORD: Root password. Always equal to DATABASE_PASSWORD for our dev setups
MYSQL_DATABASE: Database that gets created on MySql Container startup. Same as DATABASE_NAME
REDIS_HOST: Host of Redis DB
REDIS_PORT: Port of Redis DB

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>
MYSQL_DATABASE=<Same as DATABASE_NAME> 
REDIS_HOST=0.0.0.0(or host.docker.internal for windows)
REDIS_PORT=6379
  1. Bring your containers up

docker-compose up -d

  1. Restart your emba container. This step is important to create the needed database environment!

docker-compose restart emba

  1. How to exec into your emba-django container

docker exec -it embark_emba_1 bash

Testing Django setup

Test if django application (uWSGI workers) came up with the following command:

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 something in the embark directory (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
If you change code in the templates or static, just make sure your browser reloads the files e.g. just open in private browser window.

Exec inside the containers

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

  1. Paste that firmware inside directory embark
  2. Start into a shell into your container with docker exec -it embark_emba_1 bash
  3. Run your commands.

Notes to take care

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

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

Version of docker-compose: Currently our compose file is compatible with docker-compose version 1.25.xand 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 until we can test more current versions.
