#docker版本的gitlab会自动启动prometheus|grafana|alertmanager和一系列exporter,非常占用资源,且导致启动比较慢,因此我们可以通过修改 /etc/gitlab/gitlab.rb 来关闭该功能。
#查看启动的服务
ps -ef | grep -E 'prome|exporter|alert|graf'
#修改配置文件
vim /root/gitlab/config/gitlab.rb
#配置以下
alertmanager['enable'] = false
node_exporter['enable'] = false
redis_exporter['enable'] = false
postgres_exporter['enable'] = false
gitlab_exporter['enable'] = false
prometheus_monitoring['enable'] = false
#grafana['enable'] = false

#使配置生效
docker exec -it gitlab /bin/bash
gitlab-ctl reconfigure
#加载完成后会提示gitlab Reconfigured!

ps -ef | grep -E 'prome|exporter|alert|graf'
