Lunch greengrass with java command but it don't take the config file with --init-config

Question

Hello,

I try to configure a raspberry pi 4 on raspbian OS as a edge. I install greengrass on it.

I use this documentation : https://docs.aws.amazon.com/fr_fr/greengrass/v2/developerguide/manual-installation.html

I create a config file : 
```---
system:
  certificateFilePath: "/greengrass/v2/device.pem.crt"
  privateKeyPath: "/greengrass/v2/private.pem.key"
  rootCaPath: "/greengrass/v2/AmazonRootCA1.pem"
  rootpath: "/greengrass/v2/"
  thingName: "THING_NAME"
services:
  aws.greengrass.Nucleus:
    componentType: "NUCLEUS"
    version: "2.12.2" 
    configuration:
      awsRegion: "eu-central-1"
      iotRoleAlias: "GreengrassCoreTokenExchangeRoleAlias"
      iotCredEndpoint: "IOT_CREDENTIAL_ENDPOINT"
      iotDataEndpoint: "IOT_ENDPOINT"
      mqtt:
        port: 443
      greengrassDataPlanePort: 443
```

And I use this command to install Greengrass : 
`sudo -E java -Droot="/greengrass/v2" -Dlog.store=FILE \
  -jar ./GreengrassInstaller/lib/Greengrass.jar \
  --init-config ./GreengrassInstaller/config.yaml \
  --component-default-user ggc_user:ggc_group \
  --setup-system-service true`

But it create a defautl Thing but not the thing that I mention on the config file.

Thank for all who read me.

Hello,

As per the documentation that is being followed,

[+] https://docs.aws.amazon.com/fr_fr/greengrass/v2/developerguide/manual-installation.html

The IoT thing is created in the starting step of the GreenGrass configuration. Further, the same thing is used in the config.yaml file for making the setup work. Hence, as per the public documentation you might need to use the thing that was created as the starting step of the setup and use it in the config.yaml file as manual provisioning does not support this creation of thing from config file.

You could try using custom/automatic provisioning as an other option to create thing while running the java command.
