On updating the Harbor password (which has special characters having an additional line added), the issue is faced . Workload Cluster lost VIP and Control Plane and Node pool VMs are in not ready state. Containerd service is down for all VMs.systemctl status containerd
2.3
This issue is faced due to the invalid password. "/etc/containerd/config.toml" has new line in password which brought down containerd service. In later version of TCA, checks have been added to block passwords with new line added.
Note: Make sure that the password is not including any extra line in the password.
- Manually edit /etc/containerd/config.toml with the correct password .
Note: It could be overwritten by nodeconfig-daemon running on the node. It may help by killing the process returned by "ps -ef|grep nodeconfig-daemon" but it may come up again automatically. User may need to repeat this a couple of times until containerd does not crash any more after the correct password is set on WC.
