如何配置kubernetes（microk8s）以使用本地docker镜像？ [英] How to configure kubernetes (microk8s) to use local docker images?

问题描述

我已在本地构建docker映像：

I've build docker image locally:

docker build -t backend -f backend.docker

现在我要使用它创建部署：

Now I want to create deployment with it:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: backend-deployment
spec:
  selector:
    matchLabels:
      tier: backend
  replicas: 2
  template:
    metadata:
      labels:
        tier: backend
    spec:
      containers:
      - name: backend
        image: backend
        imagePullPolicy: IfNotPresent # This should be by default so
        ports:
        - containerPort: 80

kubectl apply -f file_provided_above.yaml 可以，但是后来我豆荚状态如下：

kubectl apply -f file_provided_above.yaml works, but then I have following pods statuses:

$ kubectl get pods
NAME                                   READY   STATUS             RESTARTS   AGE
backend-deployment-66cff7d4c6-gwbzf    0/1     ImagePullBackOff   0          18s

在此之前是 ErrImagePull 。所以，我的问题是，如何告诉它使用本地docker映像？我在互联网上的某个地方读到，我需要使用 microk8s.docker 构建映像，但它似乎要删除。

Before that it was ErrImagePull. So, my question is, how to tell it to use local docker images? Somewhere on the internet I read that I need to build images using microk8s.docker but it seems to be removed.

推荐答案

找到了有关如何使用私有注册表的文档： https://microk8s.io/docs/working

Found docs on how to use private registry: https://microk8s.io/docs/working

首先需要启用它：

microk8s.enable registry

然后将图像推送到注册表：

Then images pushed to registry:

docker tag backend localhost:32000/backend
docker push localhost:32000/backend

配置 image：后端需要替换为 image：localhost：32000 / backend
