Hot-reload with virtualbox Port Forwarding issue on Virtual Machine

[julienkosinski]

Hello,

The hot-reload system is based on watcher which seems to have a bug with Virtualbox synced folders...
radovskyb/watcher#26

Specifically with aah with hot-reload activated, not only events does not work on the folder on the host but also with this configuration it avoids the server from handling requests on the forwarded port 8080.

If anyone is able to help me on this it would be very nice! :)
Thank you very much!

Looks like to I need to setup an environment for this to verify. Would you mind sharing your vagrant file?

No problem, thank you very much for your help! :)

@julienkosinski I have verified using vagrant file. The steps I did and observation as follows:

• Ubuntu VM successfully created, my host machine is Mac OS Sierra.
• Your startup provision script has chmod -R o+rwx /home/ubuntu/go/, do not set +x source code files
• First I have verified within VM, does aah work as expected? Yes, it is working as expected (hot-reload, etc) using curl within VM
• Second I have verified file changes from host system. Yes, it is working as expected (hot-reload, etc) using curl within VM (see timezone is different here, still it worked. host: PST, VM: UTC)
• Then I have changed VM timezone same as host system i.e. PDT. Then performed first and second steps again. Working as expected.
• For me port forwarding didn't work, that's why I'm using curl to verified application is functioning.
  • Then I wanted to see the action in the browser. So I did SSH tunneling (vagrant ssh -- -L 8080:localhost:8080) to do port forward.
  • Now I'm able to access the application via browser. App is running within guest VM listening on port 8080.

I hope it helps and gives an idea to handle your VM issues. Closing this ticket.

Found the problem of port forwarding issue while using hot-reload server within Virtual Machine.

Issue is hot-reload server binds to localhost:8080 so virtual box or vagrant configuration do not how to forward the request for NAT bridge with IP address. As I mentioned in previous comment. SSH tunnel worked, since it was not using NAT bridge.

Solution is to bind hot-reload server to :8080. It works, it listens all IP address in the VM.

I have fixed it, please have a look.

PS: The issue I mentioned about in the gitter - 502 error in Virtual machine usage scenario. I have to investigate it.

Fixed it. Coming in v0.8 release.

@julienkosinski you can try dev version before the release and share your feedback.
