Create a Container
Deploy and manage containerized applications in VKS using Pods and Deployments
In Kubernetes, a container is the basic unit for building and running applications. A container is a lightweight, independent, executable software package that contains everything needed to run an application: code, runtime, system tools, system libraries, and settings. Containers are created and managed by a container runtime (Docker, containerd, CRI-O, etc.).
Deploy a container in a Pod
In Kubernetes, containers are managed and run inside Pods. The Pod is the smallest deployable unit, and may contain one or more containers. All containers in a Pod share the same network namespace and storage volumes.
If your container needs GPU resources, see GPU resources.
Example
apiVersion: v1
kind: Pod
metadata:
name: your-pod-name
namespace: your-namespace
spec:
imagePullSecrets:
- name: ydyd-harbor-secret
containers:
- name: your-container-name
image: your-image
imagePullPolicy: IfNotPresent
volumeMounts:
- mountPath: /mnt/test
name: your-volume-name
command: ['/bin/bash', '-c', 'while true; do sleep 30; done']
volumes:
- name: your-volume-name
persistentVolumeClaim:
claimName: your-pvc-nameManage Pods with a Deployment
A Deployment is a higher-level resource for managing stateless applications. It declaratively defines the desired state, and the controller reconciles actual state to match. Deployment makes it easy to deploy, scale, update, and roll back. In practice you'll typically use a Deployment to manage Pods.
Example
apiVersion: apps/v1
kind: Deployment
metadata:
name: your-deploy-name
namespace: your-namespace
spec:
replicas: 1
selector:
matchLabels:
app: wedding-ai-api

imagePullPolicy: IfNotPresent
volumeMounts:
- mountPath: /mnt/test
name: your-volume-name
command: ['/bin/bash', '-c', 'while true; do sleep 30; done']
volumes:
- name: your-volume-name

Use the VKS Cluster
Connect to and use a provisioned and authorized VKS cluster by configuring your kubeconfig environment variable
Create and use a registry secret
Create a Kubernetes image-pull Secret on VKS — via kubectl one-liner or YAML manifest — and reference it from your Pod with imagePullSecrets
