Mac环境下Minikube拉取本地镜像遇manifest unknown问题求助

在Mac环境下使用Minikube、Docker、Helm和本地Docker Registry，通过Helm安装应用时出现以下错误：

Failed to pull image "127.0.0.1:5000/hello-world:v1.0": rpc error: code = Unknown desc = Error response from daemon: manifest for 127.0.0.1:5000/hello-world:v1.0 not found: manifest unknown: manifest unknown

部署配置 #

spec:
    containers:
      - name: hello-world
        image: 127.0.0.1:5000/hello-world:v1.0
        imagePullPolicy: IfNotPresent
        ports:
          - name: http
            containerPort: 5000
            protocol: TCP

本地验证结果 #

本地执行拉取镜像命令可正常完成：

$docker pull 127.0.0.1:5000/hello-world:v1.0

v1.0: Pulling from hello-world
Digest: sha256:0534fcc8d406574f7def33e726f0e476ce94866e21d8cbd6ed4c273de113e9d3
Status: Image is up to date for 127.0.0.1:5000/hello-world:v1.0
127.0.0.1:5000/hello-world:v1.0

通过curl检查镜像manifest也存在：

$curl -X GET 127.0.0.1:5000/v2/hello-world/manifests/sha256:0534fcc8d406574f7def33e726f0e476ce94866e21d8cbd6ed4c273de113e9d3

{
   "schemaVersion": 2,
   "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
   "config": {
      "mediaType": "application/vnd.docker.container.image.v1+json",
      "size": 8102,
      "digest": "sha256:49188cd9fa7002b28391f01ba5c0ce4328cc467abeb6743d181cbe1a3a2fd37c"
   },
   ...
}

执行的操作步骤 #

• docker run -d -p 5000:5000 --restart=always --name registry registry:2
• docker build . -t hello-world:v1.0
• docker tag hello-world:v1.0 127.0.0.1:5000/hello-world:v1.0
• docker push 127.0.0.1:5000/hello-world:v1.0
• helm install hello-world ./hello-world

解决方案 #

1. 修改Pod/部署清单中的镜像地址为 host.minikube.internal:5000/hello-world:v1.0
2. 执行命令删除现有Minikube集群：minikube delete
3. 使用以下命令重新启动Minikube，指定不安全注册表：

minikube start --insecure-registry="host.minikube.internal:5000"
