Running applications inside the container

[marcellodesales]

Hi @gai00

How can I run the applications inside the Docker container??? Since there's only one port open 3131, I can't connect to the application when I do "Run"...

The port numbers are randomly assigned by the Cloud9 Editor... Is there a way to set a static port number instead? That way, it would be easier to run it from Docker.

Thanks a lot!

(My english is not good.)
You can set a static port.
var port = [what you want]; //ex: 20080

And run docker with -p 20080:20080 .

@gai00 Sorry but the Cloud9 Editor starts a process at a random port inside the container... :) At that moment, it is a chicken-egg problem!!! Docker needs to create the port forward before... This does not work...

Try to edit your url when url in console is not working correctly.
I almost open a new tab in browsers(IE/Firefox/Chrome/Safari) to check compatibility.

That's the whole point of this issue... Your container was assigning a random port to the RUN... This makes things completely complicated...

docker run -p 20080:20080 -p 3131:3131 -p 80:80 layer/cloud9 ...
Just add -p host_port:container_port on running.
I hope this can help you.

@gai00, I completely understand how to expose ports... All I am saying is that ports should be random as they are in Cloud9, and NEVER statically chosen...

This is the feature needed to maintain it... All my apps are configured using "env.PORT"...

@marcellodesales , We are waiting for new version Cloud9. (maybe long time)
https://github.com/ajaxorg/cloud9/issues/3200

If you want to allow random port, and specific hostname (localhost/127.0.0.1),
add -P to publish all port (docker cmd), and add tail -l hostname (cloud9 cmd, lowercase L).
EX:
docker run ... -P gai00/cloud9 -l 127.0.0.1 ...
https://github.com/ajaxorg/cloud9/#installation-and-usage

My docker file set -l 0.0.0.0 on entrypoint. (Listen to all, using host firewall to block)
