Usefull commands

Use locally built providers

1. Edit $HOME/.terraformrc
2. Add dev_overrides there to create dev aliases for used providers to point to the local build folder:

    provider_installation {
    dev_overrides {
        "Foltik/vyoS" = "/root/terraform-provider-vyos"
        "goauthentik/authentik" = "/root/terraform-provider-authentik"
        "DNSMadeEasy/dme" = "/root/go/bin"
    }
   
    direct {}
    }
   

Debugging Terraform provider

1. Start terraform plugin in debug mode: <BINARY> -debug.
   • provider must support debugging: see SDK instructions
   • in Visual Code the following block might be used under <provider source code>/.vscode/launch.json:

     {
        "version": "0.2.0",
        "configurations": [
            
            {
                "name": "Debug Terraform Provider",
                "type": "go",
                "request": "launch",
                "mode": "debug",
                // this assumes your workspace is the root of the repo
                "program": "${workspaceFolder}",
                "env": {},
                "args": [
                    "-debug",
                ]
            }
        ]
     }
     

2. Follow the instructions to run terraform using the debugged provider. Usually TF_REATTACH_PROVIDERS={...} terraform apply
