Deploy image from Container Registry

If you store Docker images in Container Registry, you can deploy under to a Managed Kubernetes cluster.

Load the image into the Container Registry.
Configure Container Registry integration with the cluster.
Deploy the application from the image.

Upload image to Container Registry

Authorize the registry.
Enter username and password.
Assign a tag to the image:
```
docker tag <image> cr.selcloud.ru/<registry>/<image>:<tag>
```
Specify:
- <image> — image name, can be viewed with docker image list;
- <registry> — name of the registry where you want to load the image;
- <tag> — Tag.

Load the image into the registry:

docker push cr.selcloud.ru/<registry>/<image>:<tag>

Configure Container Registry integration with the cluster

You can configure integration from a Managed Kubernetes cluster with one or more Container Registries.

In the dashboard, on the top menu, click Products and select Managed Kubernetes.
Open the cluster page → Settings tab.
In the Container Registry Integration block, click Customize Integration.
Select the registries to be accessed from the cluster.
If you are setting up an integration for the first time, click Integrate.
If you are changing the integration settings, click Save.

Information about Container Registry registries accessed from the cluster is displayed on the Cluster page → Settings tab → Container Registry Integration block .

Deploy an application from an image

Create a deployment.yaml file:
```
nano deployment.yaml
```

Copy the contents into the file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: example-deployment
  labels:
    app: example-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      app: example-deployment
  template:
    metadata:
      labels:
        app: example-deployment
    spec:
      containers:
      - name: <image_name>
        image: cr.selcloud.ru/<registry>/<image>:latest

Specify:

<registry> — registry name;
<image_name> — image name.

Deploy the application:
```
kubectl apply -f deployment.yaml
```
Check the status of pods — they should be in running status:
```
kubectl get pods
```
