I expected to be able to setup/config my IDEA for when the command operator-sdk up local --namespace= be executed I can debug the code.

Environment

• Kubernetes version information:

Hi @camilamacedo86, I don't know much about IDEA, haven't used it yet. But what the operator-sdk up local command does is it just starts the operator locally by doing a go build and then exec the binary file with the args you passed to it. Hopefully, that is of help?

Hi @camilamacedo86, if you what, use can use the same approach used with Vscode.
using this commands it works for me
export WATCH_NAMESPACE=default

 dlv --listen=:2345 --headless=true --api-version=2 exec ./build/_output/bin/memcached-operator-local  -- 

then attach to process using this vs code conf

    "version": "0.2.0",
    "configurations": [
        {
            "name": "test",
            "type": "go",
            "request": "launch",
            "mode": "remote",
            "remotePath": "${workspaceFolder}/cmd/manager/main.go",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${workspaceFolder}",
            "env": {},
            "args": []
        }
    ]
}

obviously you need to compile it first.

I hope this can be help

@devopsgym really tks it worked for me as follows.

1. Run export WATCH_NAMESPACE=default
2. From the dir where has the main.go run $ dlv debug --headless --listen=:2345 --api-version=2
3. From the IntelliJ IDEA setup and use the go remote debugs as follows.

1. Now, just add the breakpoints and check it working :-)

Closing this issue since shows solved.

Hi - I cannot get the debugger to stop at the breakpoints after doing the above. Like, I create a CR and expected the breakpoint for the reconcile to kick in. But, it never stopped.
