导入集群

此页面上列出的命令/步骤可用于检查要导入的集群或在 Rancher 中导入的集群。

确保您配置了正确的 kubeconfig (例如,export KUBECONFIG=$PWD/kubeconfig_from_imported_cluster.yml)

Rancher Agents

Rancher 通过 cluster-agent 与集群进行通信(通过cattle-cluster-agent调用 Kubernetes API 与集群通讯),并通过cattle-node-agent与节点进行通信。

如果 cattle-cluster-agent 无法连接到已有的 Rancher Server 也就是server-url,集群将保留在 Pending 状态,错误显示为 Waiting for full cluster configuration

cattle-node-agent

检查是否每个节点都正常运行了 cattle-node-agent,正确运行的状态应该是 Running 并且重启的次数应该不多。

kubectl -n cattle-system get pods -l app=cattle-agent -o wide

输出示例:

NAME READY STATUS RESTARTS AGE IP NODE
cattle-node-agent-4gc2p 1/1 Running 0 2h x.x.x.x worker-1
cattle-node-agent-8cxkk 1/1 Running 0 2h x.x.x.x etcd-1
cattle-node-agent-kzrlg 1/1 Running 0 2h x.x.x.x etcd-0
cattle-node-agent-nclz9 1/1 Running 0 2h x.x.x.x controlplane-0
cattle-node-agent-pwxp7 1/1 Running 0 2h x.x.x.x worker-0
cattle-node-agent-t5484 1/1 Running 0 2h x.x.x.x controlplane-1
cattle-node-agent-t8mtz 1/1 Running 0 2h x.x.x.x etcd-2

检查特定节点上 cattle-node-agent 或者所有节点上 cattle-node-agent pods 的日志是否有错误:

kubectl -n cattle-system logs -l app=cattle-agent

cattle-cluster-agent

检查集群中是否正确运行了 cattle-cluster-agent,正确运行的状态应该是 Running 并且重启的次数应该不多。

kubectl -n cattle-system get pods -l app=cattle-cluster-agent -o wide

输出示例:

NAME READY STATUS RESTARTS AGE IP NODE
cattle-cluster-agent-54d7c6c54d-ht9h4 1/1 Running 0 2h x.x.x.x worker-1

检查 cattle-cluster-agent pod 的日志是否有错误:

kubectl -n cattle-system logs -l app=cattle-cluster-agent
