    用 docker tag 重新命名,新名字中"docker.io"字符串消失了

    现在是这样,K8S 启动一个 pod 需要拉 docker.io/kubeflowkatib/suggestion-hyperopt:v0.15.0

    那么本地 docker 中存在 kubeflowkatib/suggestion-hyperopt:v0.15.0 (没有 docker.io 前缀) 也可以吗

    奇怪了,现在本地 docker 有 kubeflowkatib/suggestion-hyperopt:v0.15.0 ,但启动的 pod 里显示拉取 docker.io/kubeflowkatib/suggestion-hyperopt:v0.15.0 失败

    你 k8s 用的是 docker 引擎吗,k8s 很多年前就不是默认使用 docker 了。

    imagePullPolicy 为 Always 时会先从网络拉取镜像,然后你网络又无法访问 docker.io 。建议改成 IfNotPresent 或者 Never 。

    会先请求 manifest list 和 repo digest ,请求不到就报错拉取失败,设置下拉取策略,生产环境要内网镜像仓库

    如果是 minukube ,可以用 minikube image load 把镜像加载进去,如果是普通 k8s 集群节点,那么你需要一个 harbor 或者云厂商提供的镜像仓库,然后把镜像推上去

    6 楼正解,你把 k8s 的镜像拉取策略改一下,改成 ifNotPresent
