Image Layers on a Node

Check Items

Check the number of image layers on your node. If there are more than 5000 layers, it will take a long time for Docker or containerd to start, affecting the stdout of Docker or containerd.

If Nginx is used in your cluster, data forwarding may be slow.

Solution

Log in to the node and manually delete unnecessary images.
