kubernetes fluent-bit 日志收集

kubernetes日志收集方案：

https://kubernetes.io/zh/docs/concepts/cluster-administration/logging/

官方文档：fluent-bit --> elasticsearch

https://docs.fluentbit.io/manual/installation/kubernetes

部署：

kubectl create namespace logging
kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-service-account.yaml
kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role.yaml
kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/fluent-bit-role-binding.yaml 

kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/output/elasticsearch/fluent-bit-configmap.yaml
kubectl create -f https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/output/elasticsearch/fluent-bit-ds.yaml

        只要修改 fluent-bit-ds.yaml 中 env.name 的变量值 FLUENT_ELASTICSEARCH_HOST 将value值改为可用的elasticsearch即可。
