Question

我正在使用这张头盔图表：https://github.com/imubit/graylog-helm-chart

谁拥有elasticsearch，mongodb和graylog。我想在每个服务中都运行一个pod，而不是repica pods。

当我运行弹性搜索的单个Pod时，它将在日志节点初始化中重新启动，但没有启动Pod。

我已将此掌舵图中的gryalog版本更新为3.0.1和elasticsearch 6.5.0。

# Give owner rights to the current user
RUN chown -Rh $user:$user /project

USER $user

# Install (local) Yarn packages and build
RUN yarn

pod正在运行其他服务，但弹性搜索重新启动

在这里共享日志：

Answer 1

我必须添加

env:
          - name: discovery.type
            value: single-node
          - name: cluster.name
            value: "graylog"

环境变量，它将使单个节点成为Elasticsearch中的主节点。而容器命令将类似于

command:
          - elasticsearch
          - "-Ecluster.name=graylog"

Elasticsearch Pod没有运行重启
