@girish said in Finishing the VPN Client app's functionality:

Since, async functions can get some time to get used to, what you can do as a "hack" for now is to just set a property in appdb. For example, add a line https://git.cloudron.io/cloudron/box/-/blob/master/src/appdb.js#L59 like result.networkId = container:vpncontainerappid. Then you have this properly available in the docker.js code.

I think the final code will anyway read the networkId from the app table, so your code won't require much change if you do something like above.

That’s perfect. I hated how hacky my solution was so I’m going to to recode it in the way you described. Doing it the way you described also allows me to add a comma-delimited list of all VPN containers thus supporting more than one VPN client running simultaneously on Cloudron (my hacky code only allows for a single OpenVPN client).

I need to add the container name to the DB and the internal IP of the running vpn client container. Both are essential.

Then when any user chooses to connect to the VPN then that specific app will restart and be configured to route all outgoing traffic to it.

The only caveat in all of this is that though technically an unlimited amount of web apps can connect to the vpn client, a limitation is that the web apps can’t share the same exposed port as any of the others. This is gotten around in Docker by binding randomized ports to the exposed port. But when you connect to a VPN Client, you have to be running on the same IP so you lose the ability to Docker “bind.”

There may be a way around this using Docker Connect -link argument. But I think the same caveat would apply and that would only solve the problem of having the app not have to do a quick restart to connect. But I’ll make sure. ☺️

@jdaviescoates I’m an idiot, you’re absolutely right: https://forum.cloudron.io/topic/2686/live-stream-on-creating-an-app-for-cloudron?_=1602281676588

This is the clip that made me a Cloudron developer enthusiast. I think it could help anyone / everyone starting out.

Also, if anyone has any questions let me know. I had to take the week off work due to a hugely personal situation. But I’ll be back on Monday full steam on the forum and would love to help any new developers (in the same way @fbartels helped me, indirectly). I don’t know as much about box as @girish but if someone is making an app that needs deeper level dockerode / Docker / node knowledge - let me know. It took me 4 days to understand how node asynchronicity worked. So if I can help someone turn that into one day. I can tell you how do to so.

Note: Cloudron box uses callback Node methodology so when researching it, make sure to look into that type of methodology when it comes to handling asynchronousity since this project was started in the timeframe callbacks were the most popular.

@nebulon Yeah, I wrote this pretty exhausted. That said I could probably rewrite it sometime in the coming weeks. Basically, I made the VM because it's what I use to develop apps for Cloudron - and the OVA is nice cause I rebuild my computer every so often and kinda tired of rebuilding it over and over again. Figured if I did this, and wrote a quick tutorial on it, it could benefit everyone 🙂

@msbt I faced a similar issue with node-red. While I haven't tried it yet, I think what we want is to set NODE_PATH. See https://nodejs.org/api/modules.html#modules_loading_from_the_global_folders . I guess we set NODE_PATH=/app/data/custom-modules or something ?

Looks like importing is some admin specific functionality. Oh, well.

@d19dotca I definitely see a case for making it optional especially because then it helps those of us who want to build our apps for the Cloudron App Store to test updates out and have them deploy exactly the same as official App Store apps.

Great, this works well.

Good morning,

I found the problem. It was a supervisor misconfiguration. I copied a wrong template with a logging path that was unreachable.

Thanks

Glad it solved itself 🙂

@JOduMonT Yup, we are waiting for the next peertube release to make it stable (there is a bug in current release which makes it hard to finish the setup) and then start posting videos there.

thanks @girish makes sense!
