kubernetes - Docker for Mac - Kubernetes - 引用本地镜像

Question

我正在使用 Docker for Mac 和 Kubernetes 支持，我正在努力创建一个引用本地构建镜像的 Kubernetes 部署。
docker images 的输出:

REPOSITORY  TAG     IMAGE 
test        latest  2c3bdb36a5ed

我的 deployment.yaml :

apiVersion: apps/v1
kind: Deployment
metadata:
  name: helloworld-deployment
spec:
  selector:
    matchLabels:
      app: helloworld
  replicas: 1
  template:
    metadata:
      labels:
        app: helloworld
    spec:
      containers:
      - name: aaa
        image: test:latest
        ports:
        - containerPort: 8080

当我运行时 kubectl apply -f deplyment.yaml Pod 已创建，但是:

helloworld-deployment-764b8b85d8-2c4kl   0/1       ImagePullBackOff   0          
helloworld-deployment-764b8b85d8-rzq7l   0/1       ImagePullBackOff   0

kubectl describe这些 pod 之一给出:

  Normal   Scheduled              20s               default-scheduler            Successfully assigned helloworld-deployment-79f66d97c6-7tj2x to docker-for-desktop

  Normal   BackOff                16s               kubelet, docker-for-desktop  Back-off pulling image "test:latest"
  Warning  Failed                 16s               kubelet, docker-for-desktop  Error: ImagePullBackOff

  Warning  Failed                 2s (x2 over 17s)  kubelet, docker-for-desktop  Error: ErrImagePull

有趣的是，如果我尝试运行托管在 dockerhub 上的一些图像，那么一切都很好，
我也尝试使用 skaffold它也像一个魅力......

我看到一些关于 minikube 的类似问题，其中解决方案是使用 minikube docker daemon 来构建图像，以便可以从 Kubernetes 集群中引用它们。

我想避免设置本地存储库，那么如何使其与 Docker 的 Kubernetes 一起使用？

Answer 1

我可以通过设置 imagePullPolicy 来运行本地镜像。至 Never .

例如:

apiVersion: v1
kind: Pod
metadata:
  name: local-image-test
spec:
  containers:
  - name: local-image-container
    image: local-image:latest
    imagePullPolicy: Never
