Pulling an Image from a Self-Managed Image Repository

When an image is pulled from a self-managed image repository, the image may fail to be pulled due to different protocols or certificate authentication failures. In this section, HTTP and a self-issued certificate are used as examples to describe how to create a Deployment or pod by pulling an image from a self-managed image repository.

Configuration Description

cci.io/http-registries

"harbor.***.com,192.168.XX.XX:5000,100.95.XX.XX,http://harbor.***.com"

If you want to pull an image from a self-managed image repository using HTTP, you need to configure this annotation. The value can contain the https://prefix, port number, and relative path. Use commas (,) to separate multiple addresses, which can be private IP addresses, domain names, or public IP addresses. A maximum of 10 addresses are allowed.

cci.io/insecure-registries

"harbor.***.com,192.168.XX.XX:5000,100.95.XX.XX,https://harbor.***.com"

If you want to pull an image from a self-managed image repository using a self-issued certificate, you need to add this annotation to skip certificate authentication. The value can contain the https://prefix, port number, and relative path. Use commas (,) to separate multiple addresses, which can be private IP addresses, domain names, or public IP addresses. A maximum of 10 addresses are allowed.
  • If the image repository address has a port number, the port number must be included. For example, if the image path is 192.168.XX.XX:5000/nginx:latest, cci.io/http-registries can be set to 192.168.XX.XX:5000.
  • If HTTP is used, data transmission is not encrypted, and data is vulnerable to man-in-the-middle attacks and lacks identity authentication, which may cause data leak and service loss. HTTPS is recommended.

Example 1: Using HTTP for a Self-Managed Image Repository

  • Creating a Deployment with 2 vCPUs and 4-GiB memory 
    apiVersion: cci/v2
kind: Deployment
metadata:
  labels:
    app: http
  name: http
spec:
  replicas: 1
  selector:
    matchLabels:
      app: http
  template:
    metadata:
      labels:
        app: http
      annotations:
        resource.cci.io/pod-size-specs: 2.00_4.0
        cci.io/http-registries: 192.168.XX.XX
    spec:
      containers:
        - image: 192.168.XX.XX/harbor/nginx:latest
          name: container-0
      imagePullSecrets:
        - name: harbor-secret-new
  • Creating a pod with 2 vCPUs and 4-GiB memory 
    apiVersion: cci/v2
kind: Pod
metadata:
  annotations:
    resource.cci.io/pod-size-specs: 2.00_4.0
    cci.io/http-registries: 192.168.XX.XX
  name: http
spec:
  containers:
    - image: '192.168.XX.XX/harbor/nginx:latest'
      imagePullPolicy: IfNotPresent
      name: container-1
  imagePullSecrets:
    - name: harbor-secret

Example 2: Using a Self-Issued Certificate for a Self-Managed Image Repository

  • Creating a Deployment with 2 vCPUs and 4-GiB memory 
    apiVersion: cci/v2
kind: Deployment
metadata:
  labels:
    app: insecure
  name: insecure
spec:
  replicas: 1
  selector:
    matchLabels:
      app: insecure
  template:
    metadata:
      labels:
        app: insecure
      annotations:
        resource.cci.io/pod-size-specs: 2.00_4.0
        cci.io/insecure-registries: 192.168.XX.XX
    spec:
      containers:
        - image: 192.168.XX.XX/harbor/nginx:latest
          name: container-0
      imagePullSecrets:
        - name: harbor-secret-new
  • Creating a pod with 2 vCPUs and 4 GiB-memory 
    apiVersion: cci/v2
kind: Pod
metadata:
  annotations:
    resource.cci.io/pod-size-specs: 2.00_4.0
    cci.io/insecure-registries: 192.168.XX.XX
  name: insecure
spec:
  containers:
    - image: '192.168.XX.XX/harbor/nginx:latest'
      imagePullPolicy: IfNotPresent
      name: container-1
