docker mirror warehouse hub.docker.com cannot be accessed

1 introduce why dockerhub cannot be accessed
Recently, many friends in the group have asked why they cannot access the Docker mirror warehouse, so I also tried to access it, but it turned out that I could not access it.
Everyone’s first reaction was to give the wall, and it was terrible to be red through the ping test.
In fact, the DNS is polluted, causing many users to lose access. As for what is DNS pollution, you can check it yourself. Here we mainly explain how to solve the problem that dockerhub cannot be accessed.
2 Solutions
Due to the inaccessibility, it is extremely inconvenient for our operation and maintenance personnel and developers to use the docker image. However, we can use the following methods to solve this problem.
2.1 Using magic
(I won’t go into details here, everyone knows everything)
2.2 Use domestic image acceleration
Common domestic acceleration services:
- HKUST mirror: https://docker.mirrors.ustc.edu.cn
- NetEase: http://hub-mirror.c.163.com
- Alibaba Cloud: https://
.mirror.aliyuncs.com
Don’t talk nonsense, go directly to the order
2.2.1 docker configuration:
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["mirror acceleration address"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker # example sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://eph8xfli.mirror.aliyuncs.com"] # This is the blogger's own Aliyun mirror acceleration address, you can replace it with your own } EOF sudo systemctl daemon-reload sudo systemctl restart docker
Aliyun official website also has operating documents for different operating systems, you can check them yourself

2.2.2 containerd configuration:
Including K8S image acceleration
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"]
2.3 Use the blogger’s personal mirror warehouse
This mirror warehouse is in Alibaba Cloud, mainly including K8S-related mirrors. If you have any needs, you can contact the blogger to add relevant images.
The mirror is updated continuously and synchronously every day. Currently, there are 80+ warehouses, including new versions and commonly used mirror versions.
2.3.1 At present, there are the following mirror warehouses, which will be added in succession
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
2.3.2 How to use
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} ....
2.3.3 Pull mirror image
docker pull registry.cn-hangzhou.aliyuncs.com/waluna/kube-scheduler:[image version number] crictl pull registry.cn-hangzhou.aliyuncs.com/waluna/kube-scheduler: [image version number]
3 Summary
I personally feel that using magic is the most convenient, but many students don’t know how to use magic. So you can choose to use domestic mirror acceleration (2.2 in this article) or blogger mirror warehouse (2.3 in this article) according to your favorite method.
