fluentd无法连接elasticsearch

Question

我通过docker-compose运行堆栈EFK，堆栈启动，kibana和elasticsearch通过初始设置。Fluentd在启动时抛出以下错误:

"The client is unable to verify that the server is Elasticsearch. Some functionality may not be compatible if the server is running an unsupported product."

kibana 8.2.0elasticsearch 8.2.0

也许流利不能通过https登录，哪里找问题?

Dockerfile fluentd:

FROM fluentd:latest
# Use root account to use apk
USER root
# below RUN includes plugin as examples elasticsearch is not required
# you may customize including plugins as you wish
RUN apk add --no-cache --update --virtual .build-deps 
sudo build-base ruby-dev 
&& sudo gem install fluent-plugin-elasticsearch 
&& sudo gem sources --clear-all 
&& apk del .build-deps 
&& rm -rf /tmp/* /var/tmp/* /usr/lib/ruby/gems/*/cache/*.gem
COPY conf/fluent.conf /fluentd/etc/
COPY entrypoint.sh /bin/
USER fluent

fluentd.conf

<source>
@type forward
port 24224
bind 0.0.0.0
</source>
<match *.**>
@type elasticsearch
host elasticsearch
port 9200
user fluent
password 6M9eXThhypVjV8h
logstash_format true
logstash_prefix fluentd
logstash_dateformat %Y%m%d
</match>

在kibana中创建了fluent的用户名和密码

问题已通过降级EFK版本和更改Dockerfile解决

Dockerfile

FROM fluent/fluentd:v1.12.0-debian-1.0
USER root
RUN gem uninstall -I elasticsearch && gem install elasticsearch -v 7.17.0
RUN ["gem", "install", "fluent-plugin-elasticsearch", "--no-document", "--version", "5.0.3"]
USER fluent

docker-compose.yml
