unable to load default labels: repository does not exist | Dagger | Page 1

swift kraken Mar 11, 2023, 9:59 AM

#

I tried to push the docker image the way this link does.
https://docs.dagger.io/730264/quickstart-publish/#publish-the-application

However, it fails with the following error.

unable to load default labels: repository does not exist

Post "http://dagger/query": dial tcp 127.0.0.1:35859: connect: connection refused
Please visit https://dagger.io/help#go for troubleshooting guidance.
exit status 1

How can I resolve this error?

This is my code.

func main() {
    ctx := context.Background()

    client, err := dagger.Connect(ctx, dagger.WithLogOutput(os.Stdout))
    if err != nil {
        return nil, err
    }
    defer client.Close()

    src := client.Host().Directory("./sample-app")

    image := client.Container().Build(src)

    resp, err := image.Publish(ctx, fmt.Sprintf("ttl.sh/sample-dagger-%.0f", math.Floor(rand.Float64()*10000000)))
    fmt.Println(resp)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

Hi! Is this happening in your local machine?

swift kraken Mar 11, 2023, 4:32 PM

#

Yes!

Ok, the unable to load labels is a warning message, you can ignore it. cc @past night maybe we should add a WARN prefix there or something.

Regarding the error you're getting, seems like the Dagger engine is not running. Can you verify by doing a docker ps?

swift kraken Mar 11, 2023, 4:52 PM

#

The dagger engin seems to be activated.

$ docker ps
docker ps

I have also implemented a pipeline to run the go test, which works fine.

long epoch Mar 11, 2023, 5:01 PM

#

So it's only the publish pipeline that throws this error?

swift kraken Mar 11, 2023, 5:05 PM

#

It’s just as you said

#

Strange... I'm not in a computer now. I'll check it out later. What's your setup?

#

Linux, Mac or Windows?

swift kraken Mar 11, 2023, 5:28 PM

#

Thanks.
My environment is windows.

Trying this on my Windows box

#

Wondering if you have golang 1.20

#

prob need to update mine, let's see

#

did a choco uninstall dagger had old version and choco install dagger. Got dagger 0.4.0.

PS C:\Windows\System32> dagger
Usage:
  dagger [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  query       Send API queries to a dagger engine
  run         Runs a command in a Dagger session
  version     Print dagger version

Flags:
      --debug            show buildkit debug logs
  -h, --help             help for dagger
      --workdir string   The host workdir loaded into dagger (default ".")

Use "dagger [command] --help" for more information about a command.

#

but I shouldn't need that to be present since SDK will take care of any needed CLI and Dagger Engine container images. Will uninstall again and use Go SDK.

#

PS C:\Users\Home\go-dagger\sample-app> go version
go version go1.17.8 windows/amd64

#

had old go version . Will update to 1.20

#

but will run once first with 1.17 🙂

#

installed SDK

regarding ttl.sh...hmmm wonder if
sample-dagger-1695583 is valid for ttl.sh or if it needs to be more like sample-dagger-1695583:1h for a 1 hour time to live

#

I'll try that

#

acutally those both work ☝️

#

func main() {
    ctx := context.Background()

    client, err := dagger.Connect(ctx, dagger.WithLogOutput(os.Stdout))
    if err != nil {
        panic(err)
    }
    defer client.Close()

    src := client.Host().Directory("./sample-app")

    image := client.Container().Build(src)

    resp, err := image.Publish(ctx, fmt.Sprintf("ttl.sh/sample-dagger-%.0f", math.Floor(rand.Float64()*10000000)))
    fmt.Println(resp)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
}

#

I see it in the docs here: https://docs.dagger.io/730264/quickstart-publish/#publish-the-application:~:text=available in the-,ttl.sh,-registry. Download and (like you mentioned at top of this post 🙂 )

Thank you for checking. I have solved this problem.

This was a problem with my source code.
