# Hello World with Cloud Code

![Architecture Diagram](./img/diagram.png)

"Hello World" is a simple Kubernetes application that contains a single
[Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/) and a corresponding
[Service](https://kubernetes.io/docs/concepts/services-networking/service/). The Deployment contains a
 web server that simply prints "Hello World".

## Using the Command Line

As an alternative to using Cloud Code, the application can be deployed to a cluster using standard command line tools

#### Skaffold

[Skaffold](https://github.com/GoogleContainerTools/skaffold) is a command line tool that can be used to build, push, and deploy your container images

```bash
skaffold run --default-repo=gcr.io/YOUR-PROJECT-ID-HERE/cloudcode
```

#### kubectl

[kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) is the official Kubernetes command line tool. It can be used to deploy Kubernetes manifests to your cluster, but images must be build separately using another tool (for example, using the [Docker CLI](https://docs.docker.com/engine/reference/commandline/cli/))
