我已经使用 calico 网络插件安装了 3 个节点的 Kubernetes 集群。出于某种原因,我决定完全删除 kubernetes 并使用不同的网络插件重新安装它:Flannel。
在我尝试部署我的第一个容器之前,一切似乎都很好。
kubectl describe pod/cassandra
返回以下错误:
Unknown desc = [failed to set up sandbox container "957f68c3cbe9b230b0e2bd6729a12c340f903de568622e28e335f7b48563a445" network for pod "cassandra-d7db46b86-dz7ck": networkPlugin cni failed to set up pod "cassandra-d7db46b86-dz7ck_default" network: error getting ClusterInformation: Get https://[10.96.0.1]:443/apis/crd.projectcalico.org/v1/clusterinformations/default: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes"), failed to clean up sandbox container "957f68c3cbe9b230b0e2bd6729a12c340f903de568622e28e335f7b48563a445" network for pod "cassandra-d7db46b86-dz7ck": networkPlugin cni failed to teardown pod "cassandra-d7db46b86-dz7ck_default" network: error getting ClusterInformation: Get https://[10.96.0.1]:443/apis/crd.projectcalico.org/v1/clusterinformations/default: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")]
Normal SandboxChanged 3s (x3 over 18s) kubelet, <node name> Pod sandbox changed, it will be killed and re-created.
通过阅读错误,Kubernetes 似乎仍在使用 calico 插件,尽管我删除了它并安装了 Flannel 插件。
我怎样才能清理这个烂摊子?
