+# Public Download Mirror
+
+The public mirror is useful to make the public resources download quickly in some areas of the world. (such as China).
+
+## Configuring Kubespray to use a mirror site
+
+You can follow the [offline](offline-environment.md) to config the image/file download configuration to the public mirror site. If you want to download quickly in China, the configuration can be like:
+
+```shell
+gcr_image_repo: "gcr.m.daocloud.io"
+kube_image_repo: "k8s.m.daocloud.io"
+docker_image_repo: "docker.m.daocloud.io"
+quay_image_repo: "quay.m.daocloud.io"
+github_image_repo: "ghcr.m.daocloud.io"
+
+files_repo: "https://files.m.daocloud.io"
+```
+
+Use mirror sites only if you trust the provider. The Kubespray team cannot verify their reliability or security.
+You can replace the `m.daocloud.io` with any site you want.
+
+## Example Usage Full Steps
+
+You can follow the full steps to use the kubesray with mirror. for example:
+
+Install Ansible according to Ansible installation guide then run the following steps:
+
+```shell
+# Copy ``inventory/sample`` as ``inventory/mycluster``
+cp -rfp inventory/sample inventory/mycluster
+
+# Update Ansible inventory file with inventory builder
+declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
+CONFIG_FILE=inventory/mycluster/hosts.yaml python3 contrib/inventory_builder/inventory.py ${IPS[@]}
+
+# Use the download mirror
+cp inventory/mycluster/group_vars/all/offline.yml inventory/mycluster/group_vars/all/mirror.yml
+sed -i -E '/# .*\{\{ files_repo/s/^# //g' inventory/mycluster/group_vars/all/mirror.yml
+tee -a inventory/mycluster/group_vars/all/mirror.yml <<EOF
+gcr_image_repo: "gcr.m.daocloud.io"
+kube_image_repo: "k8s.m.daocloud.io"
+docker_image_repo: "docker.m.daocloud.io"
+quay_image_repo: "quay.m.daocloud.io"
+github_image_repo: "ghcr.m.daocloud.io"
+files_repo: "https://files.m.daocloud.io"
+EOF
+
+# Review and change parameters under ``inventory/mycluster/group_vars``
+cat inventory/mycluster/group_vars/all/all.yml
+cat inventory/mycluster/group_vars/k8s_cluster/k8s-cluster.yml
+
+# Deploy Kubespray with Ansible Playbook - run the playbook as root
+# The option `--become` is required, as for example writing SSL keys in /etc/,
+# installing packages and interacting with various systemd daemons.
+# Without --become the playbook will fail to run!
+ansible-playbook -i inventory/mycluster/hosts.yaml  --become --become-user=root cluster.yml
+```
+
+The above steps are by adding the "Use the download mirror" step to the [README.md](../README.md) steps.
