Running greengrass-cli from a greengrass component; what's going on here?

Hi, have you authorized ggc_user to use the greengrass-cli? You need to do that as described here https://docs.aws.amazon.com/greengrass/v2/developerguide/install-gg-cli.html and https://docs.aws.amazon.com/greengrass/v2/developerguide/greengrass-cli-component.html#greengrass-cli-component-configuration i.e. add the ggc_user to a group and set that group as the AuthorizedPosixGroups in component configuration for aws.greengrass.Cli component through a deployment from your AWS account. Let us know if you face any issues with that or still can't get it to work

Hello,

Yes, ggc_user's profile should be enough to run greengrass-cli component restart in another component's lifecycle.

However, please note that greengrass-cli component restart only works on a non-broken component.

When ComponentA errors, greengrass will retry its lifecycle 3 times and transition it to broken state if all retries fail. After ComponentA is in a broken state, running greengrass-cli component restart -n ComponentA cannot restart the component. The only way to resurrect it is via deployment.

Thank you but this makes no sense to me. When GreenGrass-cli is installed as a component, it defaults to gcc_user to use that user, also the user greengrass is being managed is say 'myadmin'. Manually I can execute greengrass-cli using sudo and that 'myadmin' account. When my software runs it shells using sudo -u myadmin -S etc so it has exactly the same context and security as when manually. ggc_user is already member of ggc_group and the 'myadmin' is member of ggc_group.

So, greengrass_cli is by default not executed by ggc_user?

I'm having a similar issue where I'm not able to use the Greengrass cli. Every time I get a:

Caused by: java.io.IOException: Not able to find auth information in directory: /greengrass/v2/cli_ipc_info. Please run CLI as authorized user or group.

I've been looking everywhere but I can't seem to find a feasible answer for this issue. I tried doing the following:

• Set the GGC_ROOT_PATH environment variable to /greengrass/v2.
• Add the --ggcRootPath /greengrass/v2 argument to your command as shown in the following example.

As recommended by AWS documentation (https://docs.aws.amazon.com/greengrass/v2/developerguide/gg-cli-reference.html) but I get nowhere.

Any help would be appreciated!
