为什么fluent-bit的官方掌舵图是从20开始的pods

Question

我遵循了 fluent-bit 的官方 helm chart，最终在命名空间中得到了 20 pods。我如何配置它以使用 1 个 pod？

values.yaml 中的 replicaCount 属性设置为 1。

https://github.com/fluent/helm-charts/tree/main/charts/fluent-bit

helm upgrade -i fluent-bit helm/efk/fluent-bit --namespace some-ns

kubectl get pods -n some-ns

请注意，您的模板中有两种部署类型，daemonset 和 deployment。

这由值文件的种类字段控制。

现在daemonset写入了values，所以会在不考虑affinity的情况下在每个节点上启动一个replica。

如果你想启动一个，请将 kind 设置为 Deployment，然后将 replicaCount 设置为 1 并重新部署。

values.yaml

# Default values for fluent-bit.

# kind -- DaemonSet or Deployment
kind: Deployment

# replicaCount -- Only applicable if kind=Deployment
replicaCount: 1
