docker镜像仓库hub.docker.com无法访问-解决办法

1 个人镜像站点

话不多说，直接上dockerhub个人镜像站点（每天限制10w访问，只要不被封，一直免费提供访问）

hub.axlinux.top 

速度非常快，无需魔法可以直接访问

可以进行镜像搜索

也可以查看镜像版本号

2 dockerhub为什么无法访问

最近许多群友都询问为什么无法访问Docker镜像仓库，于是我也尝试去访问，结果果然无法访问。

大家的第一反应就是给墙了，通过ping检测红的很可怕。

实际上是DNS被污染了，导致很多用户都无法访问。至于什么是DNS污染，大家可以自行查询，这里主要讲解怎么解决dockerhub无法访问的问题。

如果仅仅是dns污染，我们可以手动指定hosts文件进行访问，但是实际的ip根本访问不通。

2.1 查看dockerhub实际IP

3.228.146.75 18.210.197.188 18.206.20.10 

2.2 ping检测

全部丢包，无法访问

[root@waluna ~]# ping -c1 3.228.146.75 PING 3.228.146.75 (3.228.146.75) 56(84) bytes of data.  --- 3.228.146.75 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms  [root@waluna ~]# ping -c1 18.210.197.188 PING 18.210.197.188 (18.210.197.188) 56(84) bytes of data.  --- 18.210.197.188 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms  [root@waluna ~]# ping -c1 18.206.20.10 PING 18.206.20.10 (18.206.20.10) 56(84) bytes of data.  --- 18.206.20.10 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms  [root@waluna ~]#  

3 镜像加速

3.1 使用国内镜像加速

常见的国内加速服务：

• 科大镜像：https://docker.mirrors.ustc.edu.cn
• 网易：http://hub-mirror.c.163.com
• 阿里云：https://<你的ID>.mirror.aliyuncs.com

废话不多说，直接上命令

3.1.1 docker配置：

sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' {   "registry-mirrors": ["镜像加速地址"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker  # 示例 sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' {   "registry-mirrors": ["https://eph8xfli.mirror.aliyuncs.com"]	# 这是博主自己的阿里云镜像加速地址，大家可以更换为自己的 } EOF sudo systemctl daemon-reload sudo systemctl restart docker 

阿里云官网也有不同操作系统的操作文档，大家可以自行查阅

https://help.aliyun.com/document_detail/60750.html?spm=a2c4g.348824.0.0.742fa42dEeTNYo 

3.1.2 containerd配置：

包括K8S镜像加速

vim /etc/containerd/config.toml       [plugins."io.containerd.grpc.v1.cri".registry.mirrors]          [plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]           endpoint = ["https://docker.mirrors.ustc.edu.cn","http://hub-mirror.c.163.com"]         [plugins."io.containerd.grpc.v1.cri".registry.mirrors."gcr.io"]           endpoint = ["https://gcr.mirrors.ustc.edu.cn"]         [plugins."io.containerd.grpc.v1.cri".registry.mirrors."k8s.gcr.io"]           endpoint = ["https://gcr.mirrors.ustc.edu.cn/google-containers/"]         [plugins."io.containerd.grpc.v1.cri".registry.mirrors."quay.io"]           endpoint = ["https://quay.mirrors.ustc.edu.cn"]         [plugins."io.containerd.grpc.v1.cri".registry.mirrors."ghcr.io"]           endpoint = ["https://ghcr.dockerproxy.com"] 

3.2 使用博主个人镜像仓库

本镜像仓库在阿里云，主要包含K8S相关镜像。如果大家有所需求，可以联系博主增加相关镜像。

镜像每天持续同步更新，目前有80+仓库，包含新版和常用镜像版本。

3.2.1 目前有如下镜像仓库，后续会陆续增加

  docker.elastic.co:     - elasticsearch/elasticsearch     - kibana/kibana     - logstash/logstash     - beats/filebeat     - beats/heartbeat     - beats/packetbeat     - beats/auditbeat     - beats/journalbeat     - beats/metricbeat     - apm/apm-server     - app-search/app-search   quay.io:     - coreos/flannel     - ceph/ceph     - cephcsi/cephcsi     - csiaddons/k8s-sidecar     - csiaddons/volumereplication-operator     - prometheus/prometheus     - prometheus/alertmanager     - prometheus/pushgateway     - prometheus/blackbox-exporter     - prometheus/node-exporter     - prometheus-operator/prometheus-config-reloader     - prometheus-operator/prometheus-operator     - brancz/kube-rbac-proxy     - cilium/cilium     - cilium/operator-generic     - thanos/thanos     - cilium/certgen     - cilium/hubble-relay     - cilium/hubble-ui-backend     - cilium/hubble-ui     - cilium/cilium-etcd-operator     - cilium/operator     - cilium/startup-script     - cilium/clustermesh-apiserver     - coreos/etcd     - metallb/speaker     - frrouting/frr     - goharbor/nginx-photon     - goharbor/harbor-portal     - goharbor/harbor-core     - goharbor/harbor-jobservice     - goharbor/registry-photon     - goharbor/harbor-registryctl     - goharbor/chartmuseum-photon     - goharbor/trivy-adapter-photon     - goharbor/notary-server-photon     - goharbor/notary-signer-photon     - goharbor/harbor-db     - goharbor/redis-photon     - goharbor/harbor-exporter   k8s.gcr.io:     - dns/k8s-dns-node-cache     - metrics-server/metrics-server     - kube-state-metrics/kube-state-metrics     - prometheus-adapter/prometheus-adapter     - sig-storage/nfs-subdir-external-provisioner     - sig-storage/csi-node-driver-registrar     - sig-storage/csi-provisioner     - sig-storage/csi-resizer     - sig-storage/csi-snapshotter     - sig-storage/csi-attacher     - sig-storage/nfsplugin   registry.k8s.io:     - pause     - etcd     - conformance     - kube-proxy     - kube-apiserver     - kube-scheduler     - kube-controller-manager     - coredns/coredns     - ingress-nginx/controller     - ingress-nginx/opentelemetry     - ingress-nginx/controller-chroot     - ingress-nginx/kube-webhook-certgen     - defaultbackend-amd64     - cpa/cluster-proportional-autoscaler     - autoscaling/addon-resizer   gcr.io:     - kaniko-project/executor     - google-samples/xtrabackup     - kubebuilder/kube-rbac-proxy   docker.io:     - calico/node     - calico/typha     - calico/cni     - calico/node     - calico/kube-controllers     - calico/pod2daemon-flexvol     - kubesphere/openelb     - aledbf/kube-keepalived-vip 

3.2.2 使用方式

docker.elastic.co/kibana/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name} quay.io/csiaddons/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name} k8s.gcr.io/{image_name}  ==>  registry.cn-hangzhou.aliyuncs.com/waluna/{image_name} .... 

3.2.3 拉取镜像

docker pull registry.cn-hangzhou.aliyuncs.com/waluna/kube-scheduler:[镜像版本号] crictl pull registry.cn-hangzhou.aliyuncs.com/waluna/kube-scheduler:[镜像版本号]
