Example of a cinema microservice

Build a NodeJS microservice and deploy it to Docker

This is the repo example for the article.

Stack

We’ll use a simple NodeJS service with a MongoDB for our backend.

• NodeJS 7.5.0
• MongoDB 3.4.2
• Docker for Mac 1.13.0

Microservices

• Movies Service example
• Cinema Catalog Service example
• Booking Service example
• Payment Service example
• Notification Service example
• API Gateway Service example

How to run the cinema microservice

We need to have docker installed previously.

$ bash < kraken.sh

This will basically install every microservice and setup the docker swarm cluster

and deploy every docker service in the swarm.

To monitor the cluster in a graphic mode we can go and visit the following url: http://192.168.99.100:9000

and this will give us the rancherOS web interface.

Missing Link to Blog post

You should a link in the readme to the actual blog posts

Could you provide deployment guide for Google Cloud platform or Heroku please?

Could you provide deployment guide for Google Cloud platform or Heroku please?
When I run bash script, my laptop freeze . Maybe 8gb of memory is not enough to run chrome and run multiple node servers at the same time

Duplicate code

Hi . Why is there a duplicate code in each service like di folder

Is it not better to create a parent repo and do all stuff there and include the parent as a package in package.json ?

And what can I do if I have 6 repo with 6 micro service
How I will update all file the 6 reps ?

Thanks for your very nice tutorials

Deployment on windows

Hi - Could you please provide deployment guide for Windows 10 or Windows server?

While running kraken.sh script it prompts ">>>>>>>>>>> waiting for mongodb" and get stuck.

Timeout errors in tests

I'm getting following on newly setup step-1 project. Any ideas why?

6 passing (12s)
  3 failing

  1) Mongo Connection should emit db Object with an EventEmitter:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.


  2) Repository should get movie premiers:
     Error: Timeout of 5000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.


  3) Repository should get movie by id:
     Error: Timeout of 5000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

License missing...

Hello Crizstian,

Thanks for putting this here. I wanted to use these tutorials and modify them to deploy on CloudFoundry instead of Docker. But there is no license mentioned any where and I hesitate to use it without seeing a license. Would be great if you can include something like AGPLv2 or MIT.

Keep up the good work.

Docker errors

Hi,
When I run kraken.sh I get the following errors:
docker: Error response from daemon: error while creating mount source path '/Users/Cramirez/.docker/machine/machines/manager1': mkdir /Users/Cramirez: protocol error.

docker: Error response from daemon: error while creating mount source path '/Users/Cramirez/.docker/machine/machines/worker1': mkdir /Users/Cramirez: protocol error.

docker: Error response from daemon: error while creating mount source path '/Users/Cramirez/.docker/machine/machines/worker2': mkdir /Users/Cramirez: protocol error.

Error: No such container: api-gateway-service

Error: No such image: api-gateway-service

I can open Rancher although I can't see any workers.
Any ideas? Sorry is this is really simple I am new to Microservices and Docker.

Thanks,
Jamie

Just a Thank you

Just wanted to drop a line saying thank you for publishing this! I get Docker, I get Microservices, all conceptually, but I was really struggling to put it all together the way I wanted. Every example I found was so limited, then I found this. THANK YOU sir, this is an amazing architecture! I will be building out HapiJS/Seneca Microservices using the pattern in this library.

Nice work!

Is it possible to use Firebase's new feature, Firestore?

This is a verry good tutorialand useful for learning,but my device has problem withdocker since i use 32bit Windows OS.So what might use other options? Maybe enough with Firebase feature?

server.js ?

hi,
why in your server.js the err middleware is before the api function?

container.registerValue is not a function in booking-service/src/index.js

Running npm start

I get the error : container.registerValue is not a function when i add a catch the Promise reject in src/index.js as below

mediator.on('di.ready', (container) => {
  repository.connect(container)
    .then(repo => {
      console.log('Connected. Starting Server')
      container.registerValue({repo})
      return server.start(container)
    })
    .then(app => {
      console.log(`Server started succesfully, running on port: ${container.cradle.serverSettings.port}.`)
      app.on('close', () => {
        container.resolve('repo').disconnect()
      })
    })
    .catch((err) => {
      console.log('Promise errorrr!');
      console.log(err);
    })
})

I realise that the container that is created with 'awilix' does not contain this function normally nor does the di.proto.js create this function, am i missing something here ?
