我是ELK堆栈的新手,我想在我的k8s集群中部署ELK,我可以使用minikube进行尝试。
yaml文件全部来自kubernetes存储库:
https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/fluentd-elasticsearch
我刚刚通过添加另一行type: NodePort
使用的命令:
kubectl create -f fluentd-elasticsearch/
kubectl get pods -n kube-system
// omit some info
elasticsearch-logging-0 1/1 Running
elasticsearch-logging-1 1/1 Running
fluentd-es-v2.5.1-cz6zp 1/1 Running

当我访问minikube-ip:30345时,发现“ Kibana服务器尚未准备好”
当ssh进入minikube时,卷曲10.96.18.172:9200不起作用,我怀疑问题出在弹性搜索中。
有人可以帮助我吗?预先感谢!
