我正在使用这个头盔图：https://github.com/imubit/graylog-helm-chart
谁有弹性搜索，mongodb和graylog.i想要运行每个服务的单个pod而不是repica pods。
当我运行单弹性搜索pod时，它会在日志节点初始化中重新启动，但不会启动pod。
我已将此掌舵图中的gryalog版本更新为3.0.1和elasticsearch 6.5.0。

我要补充一下
env:
- name: discovery.type
value: single-node
- name: cluster.name
value: "graylog"
环境变量将使单个节点成为elasticsearch中的主节点。而容器命令将是
command:
- elasticsearch
- "-Ecluster.name=graylog"
