    HI, @AkihiroSuda

    I'll work on this issue, so could you assign this issue to me?

    In my investigation at this time:

    Each port mappings specified with the -p option is converted to cni.PortMapping object, which is then converted to json and then to string.

    nerdctl/pkg/cmd/container/create.go

    Line 841 in f860057

    il.ports = opts.PortMappings

    nerdctl/pkg/cmd/container/create.go

    Lines 733 to 739 in f860057

    if len(internalLabels.ports) > 0 {
    portsJSON, err := json.Marshal(internalLabels.ports)
    if err != nil {
    return nil, err
    }
    m[labels.Ports] = string(portsJSON)
    }

    The string is specified as a Label when the container is created (both nerdctl run and nerdctl compose up), but the following restriction on containerd side causes this issue's error.

    Therefore, it would be a thought to modify it accordingly, including the following logic.

    nerdctl/pkg/ocihook/ocihook.go
