filebeat生产上面镜像制作的流程

https://www.kancloud.cn/lingchen_cloud/kubernetes/2100663

1、制作docker镜像

mkdir /data/dockerfile/filebeat
cd /data/dockerfile/filebeat

准备Dockerfile
[root@hdss7-200 7.4.0]# cat Dockerfile

FROM debian:jessie

ENV FILEBEAT_VERSION=7.4.0 \
    FILEBEAT_SHA1=c63bb1e16f7f85f71568041c78f11b57de58d497ba733e398fa4b2d071270a86dbab19d5cb35da5d3579f35cb5b5f3c46e6e08cdf840afb7c347777aae5c4e11

RUN set -x && \
  apt-get update && \
  apt-get install -y wget && \
  wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-${FILEBEAT_VERSION}-linux-x86_64.tar.gz -O /opt/filebeat.tar.gz && \
  cd /opt && \
  echo "${FILEBEAT_SHA1}  filebeat.tar.gz" | sha512sum -c - && \
  tar xzvf filebeat.tar.gz && \
  cd filebeat-* && \
  cp filebeat /bin && \
  cd /opt && \
  rm -rf filebeat* && \
  apt-get purge -y wget && \
  apt-get autoremove -y && \
  apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

COPY docker-entrypoint.sh /
ENTRYPOINT ["/docker-entrypoint.sh"]

准备filebeat配置文件
[root@hdss7-200 7.4.0]# cat docker-entrypoint.sh

#!/bin/bash

ENV=${ENV:-"test"}
PROJ_NAME=${PROJ_NAME:-"no-define"}
MULTILINE=${MULTILINE:-"^\d{2}"}

cat > /etc/filebeat.yaml << EOF

set -xe

# If user don't provide any command
# Run filebeat
if [[ "$1" == "" ]]; then
     exec filebeat  -c /etc/filebeat.yaml 
else
    # Else allow the user to run arbitrarily commands like bash
    exec "$@"
fi

构建镜像

chmod +x docker-entrypoint.sh
docker build . -t harbor.od.com/infra/filebeat:v7.4.0
docker push harbor.od.com/infra/filebeat:v7.4.0

使用dubbo-demo-consumer的镜像,以边车模式运行filebeat

任意node节点
kubectl apply -f http://k8s-yaml.od.com/dubbo-server/deployment.yaml
查看kafaka结果，topic打进来，即为成功
