Deployment in Heroku

[KAXER]

Hi,
I try to deploy skynet in heroku , I install Mongo DB and redis, I update de config file and deploy but when I try to run the app , the app crash, and this message appear:

at=error code=H10 desc="App crashed" method=GET path=/ host=sycconet.herokuapp.com request_id=3d259ca6-d52e-4ac8-a894-144846c46b1f fwd="63.70.73.50" dyno= connect= service= status=503 bytes=

Do you know what is the problem??

skynet uses elasticsearch currently for logging events. Do you have elasticsearch installed in your heroku instance?

[KAXER]

Hi, kmariano
No, I don't have, but what kind of add-ons I need to install:
1.SearchBox ElasticSearch
2.Found ElasticSearch
3.Bonsai ElasticSearch

Thank you for your guideline

[octoblu]

You should be able to remove the elasticsearch section from the config.js file to suppress the elastic search logging on the platform.

Could you provide us with a better stack trace? There are no skynet-related errors in your output.

Thanks,
Chris

Hi, Chris
I tried removing elasticsearch section in the config.js and in the platform, but I have same result.

One thing important, I'm using C9, in C9 I can run your app correctly, but when I try to deploy in heroku this message appear also:
"Your repository contain untracked files, these won't be deployed to Heroku"
"Do you want to continue?"

So in this moment I don't know where is the problem, in heroku or in the repo...
can you help me?

[octoblu]

It sounds like C9 may be modifying files prior to your deployment to Heroku. #notsure

Heroku also does not allow local file access. You will need to turn off logging in the config.js by setting log: false

More error logs would help us...

[KAXER]

More tracks:
When I run the application on C9, terminal display this errors:

Heroku chooses random ports to assign for your app. You'll need to modify SkyNet to use Heroku's environment port variable.

[KAXER]

Hi, thank you for your help , I change the port and host by a variable ('process.env.PORT' , 'process.env.IP'), in server.js file:

var mqttclient = mqtt.createClient(process.env.PORT, process.env.IP, mqttsettings);
coapPort = coapConfig.port || process.env.PORT;
coapHost = coapConfig.host || process.env.IP;

But C9 display this errors :(

Also in Heroku when I try to run the app , log file display me this:

It looks like you may have missed the environment variables on restify for http.

[octoblu]

Since Heroku probably only gives your app 1 port, you may need to restrict skynet to 1 protocol (maybe http which includes websockets) try also disabling MQTT and coap after you make your environment variable change for restify.

[KAXER]

Hi, Chris
What kind of hosting do you recommend to deploy skynet ?
Maybe Heroku is not my best option

[octoblu]

I'm convinced that you can get SkyNet to run on Heroku by limiting the install to 1 port running HTTP and WebSockets. I agree that it's probably not the best option.

We run skynet.im cloud on Amazon AWS; however, I have run it on Digital Ocean as well - basically another server with VPS or SSH access allowing you to run under multiple ports.

I have even run SkyNet on my Raspberry Pi :)

[chrismatthieu]

Our config.js has been updated to support environment variables on all parameters. This should be more friendly with Heroku; however, you will still only be able to run Meshblu on 1 port for HTTP and WebSockets. MQTT and CoAP require additional ports and Heroku only allows 1 per app. You could simply disable MQTT and CoAP by leaving their environment variables out of the deploy.

Thank You Chris.
