# EKS Containers and Services {% hint style="info" %} For an end-to-end example of creating an EKS Service, see [this tutorial](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-eks-services). For a Native Docker Services example, see [this tutorial](https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-duplocloud-docker-services). {% endhint %} ## Creating a DuploCloud EKS Service 1. In the DuploCloud Portal, navigate to **Kubernetes** -> **Services**. 2. Click **Add**. **The Add Service** pane displays. 3. Complete the following fields:

Field	Description
Service Name	Give the Service a name (without spaces).
App Name	Optionally, enter an App Name for the Service. You can use this label later to filter Services.
Cloud	Select AWS from the list box.
Platform	Select EKS Linux from the list box.
Docker Image	Enter the Docker image.
Allocation Tag	Optionally, enter any allocation tags.
Replica Strategy	Select a replication strategy. Refer to the informational ToolTip () for more information.

3. Select the Service from the **NAME** column. The Service details page displays. 4. Click **Actions** to choose from the following options:


Edit	Modify the container configuration.
Restart	Stop and then start the container immediately.
Start	Start a stopped container.
Stop	Stop a running container.

## Starting, Stopping, and Restarting Multiple DuploCloud Services Using the Services page, you can start, stop, and restart multiple services simultaneously. 1. In the DuploCloud Portal, navigate to **Kubernetes** -> **Services**. 2. Use the checkbox column to select the services you want to start or stop. 3. From the **Service Actions** menu, select **Start Service**, **Stop Service**, or **Restart Service.** Your selected services are started, stopped, or restarted.

## Importing a Native Kubernetes Service Using the **Import Kubernetes Deployment** pane, you can add a Service to an existing Kubernetes namespace using Kubernetes YAML. 1. In the DuploCloud Portal, select **Kubernetes -> Services** from the navigation pane. 2. Click **Add**. The **Add Service** page displays. 3. Click the **Import Kubernetes Deployment** button in the upper right. **The Import Kubernetes Deployment** pane displays. 4. Paste the deployment YAML code, as in the example below, into the **Import Kubernetes Deployment** pane. 5. Click **Import**. 6. In the **Add Service** page, click **Next.** 7. Click **Create**. Your Native Kubernetes Service is created.

## Managing Kubernetes Containers 1. You can view and manage Containers from the DuploCloud Portal by navigating to one of two locations: * **Tenant-wide view**: Go to **Kubernetes** → **Containers**. * **Service-specific view**: Go to **Kubernetes** → **Services**, select the name of the Service, and select the **Containers** tab. 2. Click the menu icon (

) for a Container and select from the following options:

Option	Functionality
Logs	Displays container logs. When you select this option, the Container Logs window displays. Use the Follow Logs option (enabled by default) to monitor logging in real-time for a running container. See the graphic below for an example of the Container Logs window.
State	Displays container state information in a separate window, where you can select between two tabs: Container State: Shows key runtime details such as start time, restart policy, termination grace period, container image, restart count, and current state. Details: Shows the full YAML definition of the container and Pod, including metadata, labels, annotations, volumes, and status conditions.
Container Shell	Accesses the Container Shell. To access the Container Shell option, you must first set up Shell access for Docker.
Host Shell	Accesses the Host Shell.
Delete	Deletes the container.

### Downloading the Kubectl Token and KubeConfig DuploCloud provides you with a Just-In-Time (JIT) security token, for fifteen minutes, to access the `kubectl` cluster. 1. In the DuploCloud Portal, select **Administrator** -> **Infrastructure** from the navigation pane. 2. Select the Infrastructure in the **Name** column. 3. Click the **EKS** tab. 4. Copy the temporary **Token** and the **Server Endpoint** (Kubernetes URL) **Values** from the Infrastructure that you created. You can also download the complete configuration by clicking the **Download Kube Config** button.

**EKS** tab with **Download KubeConfig** button

5. Run the following commands, in a local Bash shell instance: ```shell > kubectl config --kubeconfig=config-demo set-cluster EKS_CLUSTER --server=[EKS_API_URL] --insecure-skip-tls-verify ``` ```shell > kubectl config --kubeconfig=config-demo set-credentials tempadmin --token=[TOKEN] ``` ```shell > kubectl config --kubeconfig=config-demo set-context EKS --cluster=EKS_CLUSTER --user=tempadmin --namespace=duploservices-[TENANTNAME] ``` ```shell > export KUBECONFIG=config-demo ``` ```shell > kubectl config use-context EKS ``` You have now configured `kubectl` to point and access the Kubernetes cluster. You can apply deployment templates by running the following command: ```shell > kubectl apply -f nginx.yaml ``` {% code title="nginx.yaml" %} ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment-g labels: app: nginx-deployment-g spec: replicas: 1 selector: matchLabels: app: nginx-deployment-g template: metadata: labels: app: nginx-deployment-g spec: nodeSelector: tenantname: "duploservices-stgeast1" containers: - name: nginx image: nginx:latest ports: - containerPort: 80 ``` {% endcode %} If you need security tokens of a longer duration, create them on your own. Secure them outside of the DuploCloud environment. ### Additional Resources For more detailed instructions and examples related to EKS and container deployments, see: * [Passing Kubernetes Configs and Secrets](https://docs.duplocloud.com/docs/automation-platform/kubernetes-overview/configs-and-secrets) * [Downloading and Configuring a Kubectl Token](https://docs.duplocloud.com/docs/automation-platform/kubernetes-overview/kubectl/kubectl-token) * [Setting Up Docker Registry Credentials](https://docs.duplocloud.com/docs/automation-platform/overview/aws-services/containers/docker-registry-credentials) * [Adding Pod Toleration Specs to a Container Configuration](https://docs.duplocloud.com/docs/automation-platform/kubernetes-overview/pod-toleration) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
