当es被安装在不同的端口上时，fluentd无法/显着地连接到elasticsearch
在我的docker环境中，弹性search（ES-1）暴露于端口9200，这是维护数据库数据的主要ES，所以为了logging日志，我们使用在端口9700上运行的新弹性search的fluentd-elasticsearch-kibna堆栈（ES-2）。
我无法连接fluentd到这个新的弹性search（ES-2）端口9700.让我知道如何连接fluentd以外的端口“9200”
下面是用于FEK的dockerconfiguration细节
fluentd.config : <source> @type forward port 24224 bind 0.0.0.0 </source> <match *.**> @type copy <store> @type elasticsearch host elasticsearchkibana port 9200 logstash_format true logstash_prefix fluentd logstash_dateformat %Y%m%d include_tag_key true type_name access_log tag_key @log_name flush_interval 1s </store> <store> @type stdout </store> </match> docker-compose.yml : version: '2' services: web: image: httpd ports: - "80:80" links: - fluentd logging: driver: "fluentd" options: fluentd-address: localhost:24224 tag: httpd.access elasticsearchkibana: image: elasticsearch environment: - "ES_JAVA_OPTS=-Xms512m -Xmx512m" expose: - 9800 ports: - "9700:9300" - "9800:9200" fluentd: build: ./fluentd volumes: - ./fluentd/conf:/fluentd/etc links: - "elasticsearchkibana" ports: - "24224:24224" - "24224:24224/udp" kibana: image: kibana environment: - ELASTICSEARCH_URL=http://elasticsearchkibana:9200 # - "ES_HOST=192.168.241.82" # - "ES_PORT=9700" ports: - "5601:5601" 下面是我使用上面的configuration时得到的错误信息

谢谢
你需要改变你的fluentdconfiguration如下
fluentd.config : <source> @type forward port 24224 bind 0.0.0.0 </source> <match *.**> @type copy <store> @type elasticsearch host elasticsearchkibana port 9200 logstash_format true logstash_prefix fluentd logstash_dateformat %Y%m%d include_tag_key true type_name access_log tag_key @log_name flush_interval 1s </store> <store> @type stdout </store> </match>
所以基本上添加host elasticsearchkibana并更改到port 9200 。 这是因为我们应该关注容器端口而不是主机端口
