gitlab提交代码后，经gitlab Runner打docker包，推送到docker仓库，然后kubernetes选择版本更新

logstash-5.5.0.tar.gz 从官方下载 https://www.elastic.co/cn/downloads/logstash

logstash-shipper.conf样例

input {
    file {
        path => [ "/data/logs/service/*/*.log"]
        type => "service"
        sincedb_path => "/data/logs/sincedb/service"
        codec => multiline {
            pattern => "^dddd-dd-dd dd:dd:dd.ddd .+"
            negate => true
            what => "previous"
            max_lines => 30
        }       
    }
    file {
        path => [ "/data/logs/web/*/access_log*.log"]
            codec => plain { format => "%{message}" }
        type => "web"
        sincedb_path => "/data/logs/sincedb/web"
    }
}
output {
    if [type] == 'service' {
        kafka {
            codec => plain { format => "%{message}" }
            bootstrap_servers => "139.219.*.*:9092"
        topic_id => "service"
        }
    }
    if [type] == 'web' {
        kafka {
                codec => plain { format => "%{message}" }
            bootstrap_servers => "139.219.*.*:9092"
        topic_id => "web"
        }
    }
}

service的日志开头是2017-12-01 12:01:01，所以pattern匹配时间，根据时间判断日志的起始点；web日志原封不动传过去，output到kafka集群，logstash-indexer从kafka获取日志后归入elasticsearch

logstash-indexer.conf示例

input {
        kafka {
                bootstrap_servers => "139.219.*.*:9092"
                topics => "service"
                type => "service"
        }
        kafka {
                bootstrap_servers =>"139.219.*.*:9092"
                topics => "web"
                type => "web"
        }
}
filter {
    if [type] != ['web'] {
        if "_grokparsefailure" in [tags] {
              drop { }
          }
        grok {
            match => {
                "message" => "%{TIMESTAMP_ISO8601:timestamp} %{GREEDYDATA}"
            }
        }
        date {
            match => ["timestamp","yyyy-MM-dd HH:mm:ss.SSS"]
            locale => "cn"
        }
    }
    if [type] == 'web' {
        if "_grokparsefailure" in [tags] {
              drop { }
          }
        grok {
                match => {
                    "message" => '%{IP} - - [%{HTTPDATE:time}] "%{WORD:methord} %{URIPATHPARAM:request} HTTP/%
{NUMBER:httpversion}" %{NUMBER:response} %{GREEDYDATA}'
                    }
            }
        date {
            match => ["time","dd/MMM/yyyy:HH:mm:ss +d+"]
            locale => "cn"
        }
    }
}
output {
        if [type] == 'service' {
                elasticsearch {
                        hosts => "172.16.1.1:9200"
                        index => "bbotte-service-%{+YYYY.MM.dd}"
                }
        }
        if [type] == 'web' {
                elasticsearch {
                        hosts => "172.16.1.1:9200"
                        index => "bbotte-web-%{+YYYY.MM.dd}"
                }
        }
}

最后就是gitlabci配置示例

# cat .gitlab-ci.yml
image: docker:latest

stages:
  - LogstashPubTest
  - LogstashPubProd

image-build-test:
  stage: LogstashPubTest
  script:
    - "current_date=`TZ='UTC-8' date +'%m%d%H%M'`"
    - "commit_sha=$CI_COMMIT_SHA"
    - "docker build -t bbotte.com:5000/logstash:$CI_COMMIT_REF_NAME-$current_date-${commit_sha:0:8} ."
    - "docker login -u admin -p 123456 bbotte.com:5000"
    - "docker push bbotte.com:5000/logstash:$CI_COMMIT_REF_NAME-$current_date-${commit_sha:0:8}"
  only:
    - test
image-build-master:
  stage: LogstashPubProd
  script:
    - "current_date=`TZ='UTC-8' date +'%m%d%H%M'`"
    - "commit_sha=$CI_COMMIT_SHA"
    - "docker build -t bbotte.com:5000/logstash:$CI_COMMIT_REF_NAME-$current_date-${commit_sha:0:8} ."
    - "docker login -u admin -p 123456 bbotte.com:5000"
    - "docker push bbotte.com:5000/logstash:$CI_COMMIT_REF_NAME-$current_date-${commit_sha:0:8}"
  only:
    - master

目录结构如下：

logstash$ ls -a
.   docker-entrypoint.sh  .git            logstash-5.5.0.tar.gz 
..  Dockerfile            .gitlab-ci.yml  logstash-shipper.conf
