Docker image pulling from docker.io is affected by the Great Firewall (GFW) in mainland China, making it necessary to use mirror registries for clusters. For a Kubernetes setup on Aliyun, users can configure containerd by creating a hosts.toml file in the /etc/containerd/certs.d/docker.io directory. This redirection allows continued use of the same Kubernetes configs across different regions. However, there is an initial anomaly in the configuration file paths that users must address for successful setup.
To resolve container image pulling issues in mainland China due to the GFW, it's essential to configure containerd to use mirror registries.
By creating the /etc/containerd/certs.d/docker.io/hosts.toml file, we can redirect image pulls to local mirrors while preserving our Kubernetes configuration.
