Codefresh offers several options when it comes to Kubernetes deployments:

1. Codefresh UI for on-demand deployments

This is the easiest deployment option for Kubernetes. See our[Kubernetes deployment quick start]({{site.baseurl}}/docs/quick-start/ci-quick-start/deploy-to-kubernetes/).

1. Through a dedicated[deploy step]({{site.baseurl}}/docs/pipelines/steps/deploy/) in a pipeline.

1. Through the[cf-deploy-kubernetes step]({{site.baseurl}}/docs/ci-cd-guides/kubernetes-templating/) in a pipeline

Use this to also perform simple templating on Kubernetes manifests.

1. Through a[freestyle]({{site.baseurl}}/docs/pipelines/steps/freestyle/) step with[Kustomize](https://kustomize.io){:target="\_blank"}.

See[Deployment with Kustomize]({{site.baseurl}}/docs/example-catalog/cd-examples/deploy-with-kustomize).

1. Using a freestyle step with your own`kubectl` commands

This deployment option gives you great flexibility, but assumes that you know how to work with`kubectl`. See[Custom kubectl commands]({{site.baseurl}}/docs/deployments/kubernetes/custom-kubectl-commands/).

1. Using Helm as a package manager

See our[Helm deployment to Kubernetes quick start]({{site.baseurl}}/docs/quick-start/ci-quick-start/deploy-with-helm/).

* A K8s cluster in Codefresh (see[Connecting a Kubernetes cluster]({{site.baseurl}}/docs/integrations/kubernetes/#connect-a-kubernetes-cluster)

* Familiarity with the[Codefresh YAML for pipeline definitions]({{site.baseurl}}/docs/pipelines/what-is-the-codefresh-yaml/), basic[pipeline steps]({{site.baseurl}}/docs/pipelines/steps/), and how to describe them

*[Docker registry integration]({{site.baseurl}}/docs/integrations/docker-registries/) in Codefresh

First you need a Docker image to deploy to the cluster.

If you don't have one already you can use a Codefresh pipeline to build one.

Here is a basic Codefresh pipeline scenario to build and push your image to the DockerHub registry.

{% highlight yaml %}

{% raw %}

version: '1.0'

steps:

BuildImage:

type: build

image_name: '<your_docker_repo>/<your_image_name>' #specify your future image reference here

dockerfile: Dockerfile

tag: '${{CF_BRANCH_TAG_NORMALIZED}}'

PushToDockerRegistry:

type: push

candidate: '${{BuildImage}}'

tag: '${{CF_BRANCH_TAG_NORMALIZED}}'

registry: 'dockerhub' #the name of the registry you added to Codefresh

{% endraw %}

{% endhighlight %}

Using this YAML example, we'll add an additional step to deploy the image in Dockerhub to Kubernetes.

So now you have deployed your image manually, which is great.

But, how can you trigger the deployment within your pipeline? For that you will need to add a step of type`Deploy` type to the Codefresh YAML manifest file:

{% highlight yaml %}

{% raw %}

RunningDeployScript:

title: Running Deploy Script

type: deploy

kind: kubernetes

cluster: '<cluster_name>' #the name specified when you added the cluster

namespace: <namespace_name> #the namespace you wish to deploy into

service: <service_name> #the service you would like to update the deployment in

candidate:

image: '${{BuildImage}}'

registry: 'dockerhub'

{% endraw %}

{% endhighlight %}

The full Codefresh YAML looks like this:

{% highlight yaml %}

{% raw %}

version: '1.0'

steps:

BuildImage:

type: build

image_name: '<your_docker_repo>/<your_image_name>'

dockerfile: Dockerfile

tag: '${{CF_BRANCH_TAG_NORMALIZED}}'

PushToDockerRegistry:

type: push

candidate: '${{BuildImage}}'

tag: '${{CF_BRANCH_TAG_NORMALIZED}}'

registry: 'dockerhub' #the name of the registry you added to Codefresh

RunningDeployScript:

title: Running Deploy Script

type: deploy

kind: kubernetes

cluster: '<cluster_name>' #the name specified when you added the cluster

namespace: <namespcae_name> #the namespace you wish to deploy into

service: <service_name> #the service you would like to update the deployment in

candidate:

image: '${{BuildImage}}'

registry: 'dockerhub'

{% endraw %}

{% endhighlight %}

You can now run the whole pipeline, that builds your application from source to a Docker image, pushes the image to a Docker registry, and deploys the image to your Kubernetes cluster.

Run the pipeline and the container image will be pushed to Dockerhub.

The following instructions describe how to create a new service in your Kubernetes cluster in order to deploy to it.

1. In the Codefresh UI, from Ops in the sidebar, select[**Kubernetes Services**](https://g.codefresh.io/kubernetes/services/){:target="\_blank"}.

1. Click the button**Add Service**.

1. Select the**cluster**.

1. Select the**namespace**.

1. Type an arbitrary**service name**.

1. Specify the**number of replicas**.

1. Type the name of your**pushed image**.

1. In the**“Internal Ports”** field specify the port which your application listens to.

1. In the**“Expose port”** field specify the port to be exposed to the Internet and check the checkbox.

1. Click the button**“Deploy”** to deploy the application.

Wait until the deployment is completed, and you can open the deployed application in your browser by clicking on the "endpoint" link.
