sidecar收集Tomcat日志-普通用户

1.logstash配置

[root@k8s pipeline]# cat test.conf
input {
    file {
        path => ["/tmp/localhost_access_log.2020-01-04.txt"]
        type => "nodelog"
    }
}

filter {
}
output {
    elasticsearch {
          hosts => ["192.168.1.156:9200"]
          index => "lovelog-%{+YYY.MM.dd}"
    }
    stdout {
codec => rubydebug
    }
}

2.sidecar的配置

[root@k8s sidecar]# cat tomcat2logstash.yaml
apiVersion: v1
kind: Pod
metadata:
  name: tomcat01
spec:
  containers:
  - name: tomcat01
    image: k8s.gcr.io/tomcat:centos714
    volumeMounts:
    - name: varlog
      mountPath: /docker_home/local/tomcat8/logs
  - name: logstash01
    image: k8s.gcr.io/eslogstash:7.5.1
    volumeMounts:
    - name: varlog
      mountPath: /tmp
    - name: conffile
      mountPath: /usr/share/logstash/pipeline/
    - name: yamlfile
      mountPath: /usr/share/logstash/config/
  volumes:
  - name: varlog
    hostPath:
      path: /tmp/tomcatlog
#    emptyDir: {}
  - name: conffile
    hostPath:
      path: /usr/share/logstash/pipeline/
  - name: yamlfile
    hostPath:
      path: /usr/share/logstash/config/

3.以普通用户起tomcat的Dockerfile

[root@k8s mnt]# cat Dockerfile
FROM tomcat:8
#创建目录
RUN useradd -m -d /home/logstash -u 2019 -U logstash
RUN mkdir -p /docker_home/local
#把当前目录下的jdk文件夹添加到镜像
ADD --chown=logstash tomcat8 /docker_home/local/tomcat8
WORKDIR /docker_home/local/tomcat8/webapps
USER logstash
ENV CATALINA_HOME /docker_home/local/tomcat8
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin
RUN chmod -R 777 /docker_home/local/tomcat8/logs/
EXPOSE 8080
CMD ["/docker_home/local/tomcat8/bin/catalina.sh","run"]
