拉一个本地图像在库伯纳斯运行一个荚 [英] Pull a local image to run a pod in Kubernetes

问题描述

我有一个Dockerfile创建的以下图像：

I have the following image created by a Dockerfile:

REPOSITORY TAG IMAGE ID CREATED SIZE

REPOSITORY TAG IMAGE ID CREATED SIZE

ruby / lab latest f1903b1508cb 2小时前729.6 MB

ruby/lab latest f1903b1508cb 2 hours ago 729.6 MB

我有以下YML文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: ruby-deployment
spec:
  replicas: 2
  template:
    metadata:
      labels:
        app: ruby
    spec:
      containers:
      - name: ruby-app
        image: ruby/lab
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 4567

当我创建部署时，我在pod中得到以下信息：

When I create the deployment I got the following info in the pods:

ruby-deployment-3830038651-sa4ii   0/1       ImagePullBackOff   0          7m
ruby-deployment-3830038651-u1tvc   0/1       ImagePullBackOff   0          7m

And：

 8m            2m              6       {kubelet minikube}      spec.containers{ruby}   Normal          Pulling         pulling image "ruby/lab:latest"
  8m            2m              6       {kubelet minikube}      spec.containers{ruby}   Warning         Failed          Failed to pull image "ruby/lab:latest": Error: image ruby/lab not found
  8m            2m              6       {kubelet minikube}                              Warning         FailedSync      Error syncing pod, skipping: failed to "StartContainer" for "ruby" with ErrImagePull: "Error: image ruby/lab not found"

真的有必要在Docker中注册这个？我只想在本地进行测试，并通过我的代码/回购给朋友进行测试目的

Is really necessary to have registry in docker for this? I just want to make test locally and pass my code/repo to a friend for testing purposes

谢谢

推荐答案

您可以通过运行

eval $(minikube docker-env)

然后，您可以正常构建图像，并通过kubectl正常创建您的kubernetes资源。确保您有

Then you can build your image normally and create your kubernetes resources normally using kubectl. Make sure that you have

imagePullPolicy: IfNotPresent

您的YAML或JSON规范中的

in your YAML or JSON specs.

此外，您可以有一个标志将不安全的注册表传递到minikube VM。但是，这必须在您第一次创建机器时指定。

Additionally, you can there is a flag to pass in insecure registries into the minikube VM. However, this must be specified the first time you create the machine.

minikube start --insecure-registry

您可能还想在使用私人注册表时阅读此文件
