k3s with skaffold: container can't be pulled

Question

我正在创建一个微服务 API 我想运行在本地 raspberry k3s 集群上。

目的是在开发的时候使用skaffold来部署

我遇到的问题是每次我使用 skaffold dev 我都有同样的错误:

deployment/epos-auth-deploy: container epos-auth is waiting to start: 192.168.1.10:8080/epos_auth:05ea8c1@sha256:4e7f7c7224ce1ec4831627782ed696dee68b66929b5641e9fc6cfbfc4d2e82da can't be pulled

我尝试设置一个本地 docker 注册表，它是用这个 docker-compose.yaml 文件定义的：

version: '2.0'
services:
  registry:
    image: registry:latest
    volumes:
      - ./registry-data:/var/lib/registry
    networks:
      - registry-ui-net

  ui:
    image: joxit/docker-registry-ui:static
    ports:
      - 8080:80
    environment:
      - REGISTRY_TITLE=Docker Registry
      - REGISTRY_URL=http://registry:5000
    depends_on:
      - registry
    networks:
      - registry-ui-net

networks:
  registry-ui-net:

它正在 http://192.168.1.10:8080 我的本地网络上工作。

构建和推送镜像时似乎没问题。

我也在本地电脑上设置了/etc/docker/daemon.json

{
        "insecure-registries": ["192.168.1.10:8080"],
        "registry-mirrors": ["http://192.168.1.10:8080"]
}

我在所有节点上设置了 /etc/rancher/k3s/registries.yaml:

mirrors:
  docker.io:
    endpoint:
      - "http://192.168.1.10:8080"

skaffold.yaml 看起来像这样：

apiVersion: skaffold/v2alpha3
kind: Config
metadata:
  name: epos-skaffold
deploy:
  kubectl:
    manifests:
      - ./infra/k8s/skaffold/*
build:
  local:
    useBuildkit: true
  artifacts:
    - image: epos_auth
      context: epos-auth
      docker:
        dockerfile: Dockerfile
      sync:
        manual:
          - src: 'src/**/*.ts'
            dest: .

而 ./infra/k8s/skaffold/epos-auth-deploy.yaml 看起来像这样：

apiVersion: apps/v1
kind: Deployment
metadata: 
  name: epos-auth-deploy
spec:
  replicas: 1
  selector:
    matchLabels:
      app: epos-auth
  template:

      labels:
        app: epos-auth
    spec:
      containers:
        - name: epos-auth
          image: epos_auth
          env:
            - name: NATS_URL
              value: http://nats-srv:4222
            - name: NATS_CLUSTER_ID
              value: epos
            - name: NATS_CLIENT_ID
              valueFrom:
                fieldRef:
                  fieldPath: metadata.name
            - name: JWT_KEY
              valueFrom:
                secretKeyRef: 
                  name: jwt-keys
                  key: key
            - name: JWT_PRIVATE_KEY
              valueFrom:
                secretKeyRef: 
                  name: jwt-keys
                  key: private_key
            - name: JWT_PUBLIC_KEY
              valueFrom:
                secretKeyRef: 
                  name: jwt-keys
                  key: public_key
            - name: MONGO_URI
              value: mongodb://mongodb-srv:27017/auth-service
---
apiVersion: v1
kind: Service
metadata:
  name: epos-auth-srv
spec:
  selector:
    app: epos-auth
  ports:
    - name: epos-auth
      protocol: TCP
      port: 3000
      targetPort: 3000

我做到了

skaffold config set default-repo 192.168.1.10:8080

skaffold config set insecure-registries 192.168.1.10:8080

真不知道这是怎么回事

你有什么线索吗？

Answer 1

请更改 docker.io 参考，因为它令人困惑；

mirrors:
  docker.io:
    endpoint:
      - "http://192.168.1.10:8080"

并使用带有完整注册表路径的 image，就像： registry.local:5000/epos_auth

Answer 2

我在主节点上安装了docker-ce。然后我在命令中使用 --docker 参数创建了主节点。
我在创建k3s节点的时候，定义了一个context。我忘了在 ~/.skaffold/config
中替换 default 上下文
