I have a very simple go application that works fine under Windows and Mac. (I am a golang newbie btw). The purpose of the application is to subscribe to a google cloud pubsub subscription and forward the messages to another application using REST.

The code looks like:

func getOrCreateTopic() {
    log.Infof("1")
    ctx := context.Background()

    log.Infof("2")
    topicName := viper.GetString("gce.pubsub.topic")
    log.Infof("3")
    topic = client.Topic(topicName)
    log.Infof("4")
    exists, _ := topic.Exists(ctx)
    log.Infof("5")
    if topic == nil || !exists {
        topic, err = client.CreateTopic(ctx, topicName)
        if err != nil {
            log.Errorf("Failed to create topic %s: %v", topicName, err)
            os.Exit(2)
        }
    }
}

func main() {
    ...
    getOrCreateTopic();
    ...
}

I created a docker container and published it to our kubernetes cluster in google cloud. What I see in the logs is everything until "4" and then nothing more. But the process is still shown as running in kubernetes.

I am lost, it seems like the call to the API just hangs.
