OpenDAX is an open-source cloud-native multi-service platform for building a Blockchain/FinTech exchange of digital assets, cryptocurrency and security tokens.

Minimum VM requirements for OpenDAX:

• 8GB of RAM (12GB recommended)
• 4 cores vCPU (6 cores recommended)
• 300GB disk space (SSD recommended)

A VM from any cloud provider like DigitalOcean, Vultr, GCP, AWS as well as any dedicated server with Ubuntu, Debian or Centos would work

SSH using root user, then create new user for the application

useradd -g users -s `which bash` -m app

We highly recommend using docker and compose from docker.com install guide instead of the system provided package, which would most likely be deprecated.

Docker follow instruction here: docker Docker compose follow steps: docker compose

su - app

git clone https://github.com/openware/opendax.git

cd opendax
rvm install .

bundle install
rake -T # To see if ruby and lib works

Using rake -T you can see all available commands, and can create new ones in lib/tasks

If using a VM you can point your domain name to the VM ip address before this stage. Recommended if you enabled SSL, for local development edit the /etc/hosts

Insert in file /etc/hosts

0.0.0.0 www.app.local

rake service:all

You can login on www.app.local with the following default users from seeds.yaml

Seeded users:
Email: [email protected], password: 0lDHd9ufs9t@
Email: [email protected], password: Am8icnzEI3d!

All the OpenDAX deployment files have their confguration stored in config/app.yml.

The following table lists the configurable parameters of the config/app.yml configuration file and its default values.

The following table lists configurable parameters of the config/utils.yml file:

Once you're done with the configuration, render the files using rake render:config. You can easily apply your changes at any time by running this command.

Note: be sure to append all the subdomains based on app.domain to your
/etc/hosts file if you're running OpenDax locally

The OpenDAX stack can be brought up using two ways:

1. Bootstrap all the components at once using rake service:all[start]
2. Start every component one-by-one using rake service:*component*[start]

The components included in the stack are:

• proxy - Traefik, a robust cloud-native edge router/reverse proxy written in Go
• backend - Vault, MySQL, Redis and RabbitMQ grouped together
• cryptonodes - cryptocurrency nodes such as parity [Optional]
• daemons - Peatio and Ranger daemons [Optional]
• setup - setup hooks for Peatio and Barong to run before the application starts (DB migration etc.)
• app - Peatio, Barong and the Ambassador API gateway
• frontend - the frontend application located at vendor/frontend
• tower - the Tower admin panel application located at vendor/tower
• monitoring - cAdvisor and Node Exporter monitoring tools [Optional]

For example, to start the backend services, you'll simply need to run rake service:backend[start]

Note: all the components marked as [Optional] need to be installed using
rake service:*component*[start] explicitly

Go ahead and try your own OpenDAX exchange deployment!

Any component from the stack can be easily stopped or restarted using rake service:*component*[stop] and rake service:*component*[restart].

For example, rake service:frontend[stop] would stop the frontend application container and rake service:proxy[restart] would completely restart the reverse proxy container.

Each component has a config file (ex. config/frontend/tower.js) and a compose file (ex. compose/frontend.yaml).

All config files are mounted into respective component container, except from config/app.yml - this file contains all the neccessary configuration of opendax deployment

Compose files contain component images, environment configuration etc.

These files get rendered from their respective templates that are located under templates directory.

Modify config/app.yml with correct image and run rake service:all This will rerender all the files from templates directory and restart all the running services.

Alternitavely you can update the following files:

• config/app.yml
• templates/compose/*component*.yml
• compose/*component*.yml And run rake service:component[start]

Modify config/*component*/*config* and run rake service:component[start], if you want the changes to be persistent, you also need to update templates/config/*components*/*config*

# Delete all generated files
git clean -fdx

# Re-generate config from config/app.yml values
rake render:config

# Restart the container you need to reload config
docker-compose up frontend -Vd

source ./bin/set-env.sh
rake vendor:clone
docker-compose -f compose/vendor.yaml up -d

You can easily deploy OpenDAX from scratch on Google Cloud Platform using Terraform!

To do this, just follow these simple steps:

• Fill app.yml with correct values
• Run rake terraform:apply
• Access your VM from the GCP Cloud Console

To destroy the provisioned infrastructure, just run rake terraform:destroy
