Update Greengrass Core Device Network Proxy Configuration

Question

I wonder if there is a simple way to get a component to update the Greengrass Core device network proxy? I tried updating effectiveConfig.yaml, but it seems it is overwritten upon reboot. I also tried hacking at Nucleus component recipes, but to no avail.

I have a component that allows to remotely reconfigure a device network, but the use of proxy is  tricky since Greengrass also needs to be reconfigured.

Any help appreciated

Hi, you can find guidance in the [Configure the AWS IoT Greengrass Core software documentation](https://docs.aws.amazon.com/greengrass/v2/developerguide/configure-greengrass-core-v2.html#configure-network-proxy):

`To configure a network proxy, create a deployment for the aws.greengrass.Nucleus component that merges the following configuration update. This configuration update contains the networkProxy object.
`

```json
{
  "networkProxy": {
    "noProxyAddresses": "http://192.168.0.1,www.example.com",
    "proxy": {
      "url": "https://my-proxy-server:1100",
      "username": "Mary_Major",
      "password": "pass@word1357"
    }
  }
}
```

Answer

I should have  been more clear on what I wanted.  I want the Proxy configuration to be updated programmatically by a component running on the device.

I found out about [GetConfiguration/UpdateConfiguration](https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-component-configuration.html) but whilst I can get the configuration of aws.greengrass.Nucleus programmatically, I can seem to be able to update it. Is it possible?

I could use AWS CLI through a shell sub-process, but that command requires an artifact directory and I can't seem to find a way to set that.

Help please.
