Kubernetes containerd - 无法从私有注册表中提取图像

Question

我使用 containerd 而不是 Docker 来设置 kubernetes V1.20.1。现在我无法从我的私有注册表 (Harbor) 中提取 Docker 个图像。

我已经像这样更改了 /etc/containerd/config.toml：

[plugins."io.containerd.grpc.v1.cri".registry]
  [plugins."io.containerd.grpc.v1.cri".registry.mirrors]
    [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
      endpoint = ["https://registry-1.docker.io"]
    [plugins."io.containerd.grpc.v1.cri".registry.mirrors."registry.foo.com"]
      endpoint = ["https://registry.foo.com"]
  [plugins."io.containerd.grpc.v1.cri".registry.configs]
    [plugins."io.containerd.grpc.v1.cri".registry.configs."registry.foo.com"]
      [plugins."io.containerd.grpc.v1.cri".registry.configs."registry.foo.com".auth]
        username = "admin"
        password = "Harbor12345"

但这没有用。拉取失败并显示消息：

Failed to pull image "registry.foo.com/library/myimage:latest": rpc error: code = Unknown
desc = failed to pull and unpack image "registry.foo.com/library/myimage:latest": failed to 
resolve reference "registry.foo.com/library/myimage:latest": unexpected status code 
[manifests latest]: 401 Unauthorized

我的 Harbor 注册表可通过 HTTPS 使用 Let's Encrypt 证书访问。所以 https 应该不是这里的问题。

即使我尝试创建一个 docker-secret 也没有用：

kubectl create secret docker-registry registry.foo.com --docker-server=https://registry.foo.com --docker-username=admin --docker-password=Harbor12345 --docker-email=info@foo.com

谁能给我一个例子，说明如何使用 containerd 在 Kubernetes 中配置私有注册表？

Answer 1

在pod/deployment规范中设置imagePullSecrets：

apiVersion: v1
kind: Pod
metadata:
  name: private-reg
spec:
  containers:
  - name: private-reg-container
    image: <your-private-image>
  imagePullSecrets:
  - name: registry.foo.com
