docker镜像仓库hub.docker.com无法访问-解决办法

文章主要内容:

  • 个人镜像站点

  • dockerhub为什么无法访问

  • 镜像加速

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

3.228.146.7518.210.197.18818.206.20.10

2.2 ping检测

全部丢包,无法访问

[root@waluna ~]# ping -c1 3.228.146.75PING 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 18.210.197.188PING 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 18.206.20.10PING 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://.mirror.aliyuncs.com

废话不多说,直接上命令

3.1.1 docker配置:

sudo mkdir -p /etc/dockersudo tee /etc/docker/daemon.json <<-'EOF'{  "registry-mirrors": ["镜像加速地址"]}EOFsudo systemctl daemon-reloadsudo systemctl restart docker# 示例sudo mkdir -p /etc/dockersudo 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}EOFsudo systemctl daemon-reloadsudo 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]
