elastalert实现飞书机器人告警-docker
文章目录
有两种方法:
方法1:直接使用官方Dockerfile自建镜像。有缺点:可能无法构建镜像,毕竟是在国内,可以用国外的服务器创建镜像
git clone https://github.com/gpYang/elastalert-feishu-plugin
git clone https://github.com/jertel/elastalert2[root@yinjiaxing elastalert2]# ls
CHANGELOG.md CONTRIBUTING.md docs elastalert-feishu-plugin LICENSE README.md requirements.txt setup.cfg tests
chart Dockerfile elastalert examples Makefile requirements-dev.txt SECURITY.md setup.py
[root@yinjiaxing elastalert2]# pwd
/opt/elastalert2/elastalert2
[root@yinjiaxing elastalert2]# cat Dockerfile

ENV TZ "UTC"WORKDIR /opt/elastalert
ENTRYPOINT ["/opt/elastalert/run.s
方法2:直接使用镜像,只需要docker pull,然后拉取elastalert_modules,启动容器后将elastalert_modules放到容器中
docker pull jertel/elastalert2# 可以使用docker-compose启动
[root@ops elastalert]# cat config.yaml
rules_folder: /opt/elastalert/rulesrun_every:seconds: 30
buffer_time:minutes: 2
es_host: 172.18.xxx
es_port: 9200
es_username: "elastic"
es_password: "Sxxxxxxxxxxx"
writeback_index: elastalert_status
max_scrolling_count: 1
alert_time_limit:days: 2#下面的docker-compose文件内容是自建的镜像而创建的容器
[root@ops elastalert]# cat docker-compose.yml
version: '3.8'services:elastalert:container_name: elastalertfsimage: elastalertfs:1.0pull_policy: neverrestart: alwaysvolumes:- /opt/elastalert/config.yaml:/opt/elastalert/config.yaml- /opt/elastalert/rules:/opt/elastalert/rules- /etc/localtime:/etc/localtime
[root@ops elastalert]# 如果是使用docker pull拉的jertel/elastalert2,还需要拉取git clone https://github.com/gpYang/elastalert-feishu-plugin,然后需要将elastalert-feishu-plugin下的feishu_alert.py cp到jertel/elastalert2(可以先启动容器,然后cp进去,因为飞书告警中需要用到feishu_alert.py中的模板)。
举例:
root@7a58e59f9e85:/opt/elastalert/rules# cat ToolsAppStatus500.yaml
name: nginx-access-alert
