I have 1 rancher server(v2.6.9) running with docker container, 1 master node, 2 worker nodes, I want to add a new worker node to the cluster, but when I run registration command on new server, it show me below: # curl --insecure -fL https://192.168.0.57:8443/system-agent-install.sh | sudo sh -s - --server https://192.168.0.57:8443 --label 'cattle.io/os=linux' --token zxmdxmxdlwbgllpmf5zcwmr5rjg7bcb5nt7lv7k66rw6qz94k59tpd --ca-checksum 3a76abfb81778a09e15616d979bc298475dafab642b96daf23ff54b8c0a24b04 --worker % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 29798 0 29798 0 0 2645k 0 --:--:-- --:--:-- --:--:-- 2645k [INFO] Label: cattle.io/os=linux [INFO] Role requested: worker [INFO] Using default agent configuration directory /etc/rancher/agent [INFO] Using default agent var directory /var/lib/rancher/agent [INFO] Determined CA is necessary to connect to Rancher [INFO] Successfully downloaded CA certificate [INFO] Value from https://192.168.0.57:8443/cacerts is an x509 certificate [INFO] Successfully tested Rancher connection [INFO] Downloading rancher-system-agent binary from https://192.168.0.57:8443/assets/rancher-system-agent-amd64 [INFO] Successfully downloaded the rancher-system-agent binary.
