我使用stable/elasticsearch
图表并通过以下命令将elastichsearch部署到我的AWS EKS中以进行记录:
helm install stable/elasticsearch --namespace logging --name elasticsearch --set data.terminationGracePeriodSeconds=0
一旦安装,在日志记录下运行的所有Pod都处于“运行中”但未处于就绪状态
NAME READY STATUS RESTARTS AGE
elasticsearch-client-64bb574bff-85lp9 0/1 Running 0 41s
elasticsearch-client-64bb574bff-t4h6r 0/1 Running 0 44m
elasticsearch-data-0 0/1 Pending 0 44m
elasticsearch-master-0 0/1 Pending 0 44m
我从elasticsearch pod日志中得到了这个警告
[elasticsearch-client-647c67f49d-npjp4] not enough master nodes discovered during pinging (found [[]], but needed [2]), pinging again
[2018-11-27T22:53:55,009][WARN ][o.e.d.z.UnicastZenPing ]
[elasticsearch-client-647c67f49d-npjp4] failed to resolve host
[elasticsearch-discovery] java.net.UnknownHostException: elasticsearch-discovery: Name or service not known
更新
helm template ./charts/stable/elasticsearch --namespace logging --name elasticsearch --set data.terminationGracePeriodSeconds=0 > deployment.yaml
这是头盔安装的模板

我修复了添加PVC
和StorageClass
的问题,因为事件日志来自master-0,而data-0是未绑定PVC的
