通過自定義方案采集應用日志

更新時間：
產(chǎn)品詳情
我的收藏

部署在容器計算服務 ACS（Container Compute Service）的應用除了使用阿里云日志服務（SLS）采集日志之外，還可以構(gòu)建自己的日志采集系統(tǒng)，比如：EFK（ElasticSearch，F(xiàn)ileBeat，Kibana）。由于ACS不支持部署DaemonSet組件，因此日志采集Agent FileBeat需要使用Sidecar的形態(tài)進行日志采集，本文主要介紹如何在ACS上部署自定義的日志采集Agent。

前提條件

已創(chuàng)建ACS集群。具體操作，請參見創(chuàng)建ACS集群。

背景信息

常見的日志采集方案都會有一個Agent用于采集業(yè)務日志，即在每個Pod實例中，除業(yè)務容器外，運行一個Sidecar容器作為日志Agent（例如：FileBeat），用于采集業(yè)務容器產(chǎn)生的日志。

重要

Sidecar模式日志采集Agent必須和業(yè)務容器共享日志目錄，業(yè)務容器將日志寫入到共享目錄中，Logtail通過監(jiān)控共享目錄中日志文件的變化并采集日志。

采集的日志可以分為以下兩種：

  • 標準輸出

    采集標準輸出依賴于Medium為Stdout的EmptyDir卷。創(chuàng)建Pod時可以將該卷掛載到Sidecar容器上，Sidecar可以直接以文件的方式訪問ACS基礎組件收集的標準輸出日志。

    說明

    • 每個Pod最多可以聲明1個Medium為Stdout的EmptyDir卷，并需要掛載到至少1個容器內(nèi)。

    • 采集標準輸出會帶來一定的性能開銷和存儲成本。

    • 標準輸出日志已配置自動輪轉(zhuǎn)，具體規(guī)則參考日志輪轉(zhuǎn)。其中，每個日志文件到達10MiB之后將啟動輪轉(zhuǎn)，并且每個容器允許的最大文件數(shù)為5。

  • 文本文件

    采集文本文件可以通過Pod內(nèi)共享的volume實現(xiàn)。Pod內(nèi)同一個volume可以掛載到多個容器，Sidecar可以直接收集業(yè)務容器輸出到對應volume內(nèi)的文本文件。

功能介紹

容器啟動和退出順序和Job類Pod

Sidecar容器常需要如下兩個訴求：

  • Sidecar容器需要在業(yè)務容器前啟動，在業(yè)務容器后推出。

  • 對于Job類Pod而言，Sidecar容器需要在業(yè)務容器退出后主動退出。

在ACS場景下，你可以在Sidecar容器上面設置環(huán)境變量__IS_SIDECAR__="true"來實現(xiàn)上述訴求。更多信息，請參見配置Sidecar容器啟停順序。

Sidecar模式采集容器文件日志

Sidecar容器如果是采集業(yè)務容器的文件日志，可以通過共享volume的方式。更多信息，請參見使用Sidecar模式采集業(yè)務容器文件日志。

Sidecar模式采集容器標準輸出

在ACS場景下，可以通過配置volumes.emptyDir.medium=Stdout來實現(xiàn)采集容器標準輸出的效果。詳細配置，請參見場景一。

場景一：采集應用文件日志和標準輸出

  1. 使用以下內(nèi)容，創(chuàng)建一個包含F(xiàn)ilebeat Sidecar容器的Deployment。

    您可以用相同的方式配置StatefulSet。

場景三：基于OpenKruise SidecarSet自動注入Sidecar容器

上述提供的方法需要Sidecar容器配置到每個工作負載當中，在工作負載比較多的情況下，會比較大的增加用戶的工作量。OpenKruise的SidecarSet提供了一種對Sidecar容器的管理能力，能夠自動注入和獨立升級Sidecar容器，進而做到一次配置自動注入的效果。詳細信息，請參見向虛擬節(jié)點中的Pod注入Sidecar容器。
