curl -sSL https://get.rvm.io | bash -s stable

Bundle install depedencies

bundle
rake -T

Run everything

rake service:all

Insert in file /etc/hosts

0.0.0.0 www.app.local
0.0.0.0 monitor.app.local

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

Usage

Initial configuration

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

Feel free to fill it out with correct values:

Parameter	Description
app.name	Global application name
app.domain	Base domain name to be used
ssl.enabled	Enable SSL certificate generation
ssl.email	Email address to use for SSL generation requests
images	Application images tags
vendor	Frontend application Git repo URL

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 MicroKube locally

Bringing up the stack

The MicroKube 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 Geth [Optional]
• daemons - Peatio daemons and Ranger [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

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 deployment on www.your.domain!

Stopping and restarting components

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.

Accessing the deployment

Note: Make sure your VM of choice has its firewall rules configured to let in
HTTP and/or HTTPS traffic and your DNS entries are pointing at its external IP.

All the components with external endpoints are accessible by their respective subdomains based on the domain provided in the configuration:

• www.base.domain - frontend application and Peatio and Barong APIs mounted on /api
• peatio.base.domain - Peatio UI and API
• barong.base.domain - Barong API
• tower.base.domain - the Tower admin panel application
• monitor.base.domain - Traefik's dashboard useful for monitoring which components are enabled
• ws.ranger.base.domain - Ranger's WebSocket endpoint [Optional]
• eth.base.domain - Geth JSON RPC API [Optional]

Using Vendor

Fill in the list of vendor to clone in app.yaml

Render compose file

rm compose/vendor.yaml
rake render:config

Review the generated file

Clone the vendors and start

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