For nodes with a Docker runtime environment, because Docker itself does not support acceleration configuration except for docker.io, when you use container images other than docker.io from outside the Chinese mainland, you need to run the following command to change the image address domain name from quay.io to quay.tencentcloudcr.com. See the example below:

docker pull quay.tencentcloudcr.com/k8scsi/csi-resizer:v0.5.0

For nodes with a Containerd runtime environment, because Containerd itself supports acceleration address configuration for any image repository, you can modify the Containerd configuration to implement automatic accelerated pulling of images without changing the image address. This is suitable for scenarios where large numbers of images outside the Chinese mainland need to be pulled because it saves you the trouble of modifying large numbers of addresses through a complex procedure.

1. When TKE adds nodes or uses a node pool, you can write the nodes into a custom script and use the script to modify the Containerd configuration of the newly added nodes and add an acceleration address for images outside the Chinese mainland. See the sample script below:
   
   sed -i '/[plugins.cri.registry.mirrors]/ a\ \ \ \ \ \ \ \ [plugins.cri.registry.mirrors."quay.io"]\n\ \ \ \ \ \ \ \ \ \ endpoint = ["https://quay.tencentcloudcr.com"]' /etc/containerd/config.toml

   
   Alternatively, you can manually modify the Containerd configuration (/etc/containerd/config.toml) of existing nodes by adding a configuration similar to the following sample:
   
   [plugins.cri.registry]
   [plugins.cri.registry.mirrors]
   [plugins.cri.registry.mirrors."quay.io"]
   endpoint = ["https://quay.tencentcloudcr.com"]
   [plugins.cri.registry.mirrors."docker.io"]
   endpoint = ["https://mirror.ccs.tencentyun.com"]

   
   >? You can also use Ansible to perform batch modification on the Containerd configurations of existing nodes. For more information, see Performing batch operations on TKE nodes by using Ansible.
2. Run the following command to restart Containerd. See the sample below:
   
   systemctl restart containerd

3. Run the following command to use the original image address to pull images. See the sample below:
   
   crictl pull quay.io/k8scsi/csi-resizer:v0.5.0
