使用Docker搭建Fluentd

說明：
1.該鏡像內默認配置文件路徑是/fluentd/etc/fluent.conf
2.該鏡像默認啟用tcp的5140和24224端口
3.鏡像dockerhub地址：https://hub.docker.com/_/fluentd
4.版本

# 拉取鏡像
docker pull fluentd 

# 創建掛載目錄和配置文件
mkdir -p /opt/fluentd/
cd /opt/fluentd/

vim fluentd.conf
<source>
  @type http
  @id input_http
  bind 0.0.0.0
  port 5140
</source>

<match test.cycle>
  @type stdout
  @id output_stdout
</match>

# 啟動容器
docker run -it -d -p 5140:5140 --name=fluentd -v /opt/fluentd/fluent.conf:/fluentd/etc/fluent.conf fluentd

# 查看容器
docker ps
