How to pull private library images when deploying Kubernetes resources in CODING?

When deploying Kubernetes resources in CODING, pulling private library images typically involves configuring Kubernetes to authenticate with your private container registry. Here's how you can do it:

1. Create a Kubernetes Secret: First, you need to create a secret in Kubernetes that contains the credentials required to access your private registry. This secret will be used by Kubernetes to authenticate when pulling images.

   kubectl create secret docker-registry my-registry-secret \
     --docker-server=DOCKER_REGISTRY_SERVER \
     --docker-username=DOCKER_USER \
     --docker-password=DOCKER_PASSWORD \
     --docker-email=DOCKER_EMAIL
   

   Replace DOCKER_REGISTRY_SERVER, DOCKER_USER, DOCKER_PASSWORD, and DOCKER_EMAIL with your actual registry server URL and credentials.

2. Use the Secret in a Pod: Once the secret is created, you can reference it in your Pod configuration to pull the private image.

   apiVersion: v1
   kind: Pod
   metadata:
     name: my-private-repo-pod
   spec:
     containers:
     - name: my-private-repo-container
       image: DOCKER_REGISTRY_SERVER/my-private-repo-image:tag
     imagePullSecrets:
     - name: my-registry-secret
   

   Replace DOCKER_REGISTRY_SERVER and my-private-repo-image:tag with your actual registry server URL and image details.

Example:
If your private Docker registry is hosted at myregistrydomain.com and you want to pull an image my-private-repo-image:latest, your secret creation command would look like this:

kubectl create secret docker-registry my-registry-secret \
  --docker-server=myregistrydomain.com \
  --docker-username=myuser \
  --docker-password=mypassword \
  --docker-email=myemail@example.com

And your Pod configuration would be:

apiVersion: v1
kind: Pod
metadata:
  name: my-private-repo-pod
spec:
  containers:
  - name: my-private-repo-container
    image: myregistrydomain.com/my-private-repo-image:latest
  imagePullSecrets:
  - name: my-registry-secret

Recommendation for Cloud Services:
If you are using Tencent Cloud, consider leveraging Tencent Container Registry (TCR) for hosting your private Docker images. TCR integrates seamlessly with Kubernetes, making it easier to manage and deploy your containerized applications. You can use TCR credentials to create Kubernetes secrets and pull images directly from TCR during deployment.
