Mandrake is an application generator for Clever-Cloud:

• it helps you with providing walking skeletons of web applications or addon
• and with creating and pushing your application on Clever-Cloud for the first-time
• when you'll feel confident, you'll be able to add your own templates of creation

WIP

Currently, Mandrake doesn't run on Windows (but WIP)

You have to install the Clever-Cloud CLI: https://www.clever-cloud.com/doc/clever-tools/getting_started/

• git clone this repository
• cd mandrake
• npm install
• npm link

Tips: to remove the link: open /usr/local/bin/ and remove the link

mandrake comes with several default templates (see the /templates directory). Here, this is a tutorial on how to use some of these generators to create a microservices architecture:

I want to create a microservices architecture with Vert.x, Scala and Redis.

I'm going to create:

• a redis Clever-Cloud addon, because I use the Redis Vert.x Discovery Backend
• a Vert.x microservice
• a Vert.x web application to call the microservice

So, first, create a directory (and go inside), and launch mandrake:

mkdir microservices-demo
cd microservices-demo
mandrake

The first time you run mandrake in an empty directory, mandrake copies the default templates in the current directory...

... And mandrake creates a small database to keep project informations

Select the addon-redis-small (mandrake will create and deploy a "small" redis database on Clever-Cloud)

Explain:

• where you want to deploy the redis database
• type the name of your organization on Clever-Cloud
• give a name to your addon and type enter

Run mandrake again, and choose the app-discoverable-ms-vertx-scala-m item (mandrake will create and deploy a scala application on an sized "M" instance on Clever-Cloud)

Then, explain:

• where you want to deploy the microservice
• type the name of your organization on Clever-Cloud
• give a name to your project
• give a display name
• give a domain name
• give a name to the main scala file (the source code and the project structure will be generated by mandrake)
• give an id for the microservice (it will be registered with it)
• type the name of the previous redis addon and type enter

So, mandrake will create the git repository, the project structure and deploy it to Clever-Cloud

You can check that the application and the addon have been created and deployed to Clever-Cloud:

And this is the generated code:

Once the microservice deployed, you can check the redis database:

And try the operations of the microservice:

• http://amazing-calculator.cleverapps.io/api/add/38/4
• http://amazing-calculator.cleverapps.io/api/multiply/21/2

Now, it's time to create the code to use this microservice.

There is a template generator for this too.

Run mandrake again, and choose the app-invoke-ms-vertx-scala-m item (mandrake will create and deploy a scala application on an sized "M" instance on Clever-Cloud)

Then, explain:

• where you want to deploy the microservice
• type the name of your organization on Clever-Cloud
• give a name to your project
• give a display name
• give a domain name
• give a name to the main scala file (the source code and the project structure will be generated by mandrake)
• give the id of the microservice to call
• type the name of the previous redis addon and type enter

So, mandrake will create the git repository, the project structure and deploy it to Clever-Cloud

You can check that the application has been created and deployed to Clever-Cloud:

And this is the generated code:

Now you can call the two demo routes of the web application:

• http://use-calculator.cleverapps.io/add
• http://use-calculator.cleverapps.io/multiply

That's all! ✌️

Now each time you update a project, you just have to do this to deploy again:

git add .
git commit -m "my new killer feature"
git push clever master # if you want to deploy the master branch
