containerd.sock

Check Items

Check whether the containerd.sock file is on the node. This file affects the startup of container runtime in the Euler OS.

Solution

Scenario: The Docker used by the node is the customized Euler-docker.

1. Log in to the node.
2. Run the rpm -qa | grep docker | grep euleros command. If the command output is not empty, the Docker used on the node is Euler-docker.
3. Run the stat /run/containerd/containerd.sock command. If the file exists, Docker startup will fail.
4. Run the rm -rf /run/containerd/containerd.sock command and perform the cluster upgrade check again.
