[question] can't load config file using `CONFIG` env

[anubhav06]

Description

As mentioned in the README, we can load config file using the CONFIG env. However, we are unable to load config file path using the CONFIG environment variable. Kubevuln always defaults to searching the config file in the /etc/config path, even when we define a new path in the CONFIG env.

In order to run kubevuln:

• We either add the config file named clusterData.json in the path /etc/config, the default path where kubevuln searches for it.
• Or, we explicitly define a new path in the code here, where we want Kubevuln to search for the config file named clusterData.json, build kubevuln and then run it

If we follow any of the above 2 steps, then I am able to run it locally

Environment

OS: Ubuntu 20.04.4 LTS

Steps To Reproduce

Method 1:

1. Build kubevuln using make
2. Load config file using the CONFIG environment variable export CONFIG=path/to/clusterData.json

Method 2:

1. Build the Docker image from the Dockerfile and run it using: docker run <kubevuln-built-image-name> -e CONFIG=path/to/clusterData.json

Additional Context

Is this an expected behavior or am I missing something?

• I can build kubevuln as a standalone (confirmed by checking the endpoints).

  1. I used the snippet of clusterData.json given in the README, i.e., after replacing the accountID and clusterName. And saving the file in the expected location, i.e./etc/config/clusterData.json

     {
     "gatewayWebsocketURL": "127.0.0.1:8001",
     "gatewayRestURL": "127.0.0.1:8002",
     "kubevulnURL": "127.0.0.1:8080",
     "kubescapeURL": "127.0.0.1:8080",
     "eventReceiverRestURL": "https://report.armo.cloud",
     "eventReceiverWebsocketURL": "wss://report.armo.cloud",
     "rootGatewayURL": "wss://ens.euprod1.cyberarmorsoft.com/v1/waitfornotification",
     "accountID": "*********************",
     "clusterName": "******" 
     } 

  2. I also tried using another format of the clusterData.json through the command given below:

  kubectl config view -o json

• Although, I am unable to build the Docker image from the Dockerfile.

Thank you for raising this issue. You can either manually edit the path here or contribute a fix :)

@dwertent For a fix, what path should it be looking for?

@anubhav06 @dwertent Please review my PR. Please suggest any improvements. Thank You.

@anubhav06 why do you want to relocate the config, is it specific to your cluster? Maybe we can just drop the documentation instead...

[anubhav06]

@matthyx The problem was that LoadConfig was unable to load config file path set by the CONFIG environment variable.

However, as david mentioned, we are able to run it by manually editing the path and then running it.

You can either manually edit the path here

So I believe if we just remove/update the documentation, that works.
