Can fn command run locally?

[sss0350]

Hello there, just want to very impress by iron-function features.
We are trying to adopt in enterprise environment with network protection. (can only access intranet)
I've successfully running basic function & function-ui functionality on our linux (centOS).
But I encounter some issues while using fn command, I'm using following fn binary.
https://github.com/iron-io/functions/releases/download/0.2.71/fn_linux
It seems some command needs internet access to complete?
I'll give 2 samples of my failure command. Please help give me some solutions , I want to know if there's any way to pre-download some images or file command line need beforehand? Please kindly told me what to download and where to put it.

a) fn apps list
unexpected error: [GET /apps][404] GetApps default &{Error:}

b) fn routes list myapps
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x9999ff]

Hello,

Thank you for your interest in our platform !

fn tool itself shouldn't require internet connectivity. If the functions service is running on another machine, you need to supply API_URL env when making fn calls though. Please check :

functions/docs/operating/options.md

Line 16 in 3c4261a

| API_URL | The primary IronFunctions API URL to that this instance will talk to. In a production environment, this would be your load balancer URL. | N/A |

like this :

API_URL=192.168.10.11:4000 fn apps list

hope this helps ! 👍

Hello @c0ze,
Thanks for your quick reply! At first, I'm getting some trouble to make it work. fn command still can't get API_URL from my environment variables.
And then I find your release page , there's a bug fix about API_URL.... 3 days before....
And I download it, put it to /usr/local/bin , it works like a charm!
I'll detail testing all other functions tmr , thank you!

@sss0350 thanks for checking and the feedback ! Yes, in your initial message you linked to 0.2.71 so I thought you already had the latest version. I'm glad that updating fixed your issue !

Please let us know if you run into any other problems !
