在Ubuntu中使用Grafana对Docker进行监控

随着容器技术的普及，Docker已经成为了现代软件开发和部署的标准，为了更好地管理和监控Docker容器，我们可以使用Grafana这个强大的开源数据可视化工具，本文将介绍如何在Ubuntu系统中安装和使用Grafana对Docker进行监控。

安装Docker和Dockercompose

我们需要在Ubuntu系统中安装Docker和Dockercompose，Docker是一个开源的应用容器引擎，可以让开发者轻松地打包应用及其依赖到一个可移植的容器中，然后发布到任何流行的Linux机器或Windows机器上，Dockercompose是一个用于定义和运行多容器Docker应用程序的工具。

1、安装Docker：

sudo aptget update
sudo aptget install dockerce dockercecli containerd.io

2、安装Dockercompose：

sudo curl L "https://github.com/docker/compose/releases/download/1.29.2/dockercompose$(uname s)$(uname m)" o /usr/local/bin/dockercompose
sudo chmod +x /usr/local/bin/dockercompose

安装并配置Prometheus和Grafana

接下来，我们需要安装Prometheus和Grafana，并将它们配置为监控Docker容器，Prometheus是一个开源的监控和告警工具，可以收集各种指标数据，Grafana是一个开源的数据可视化工具，可以将Prometheus收集到的数据以图表的形式展示出来。

1、下载Prometheus和Grafana的Docker镜像：

docker pull prom/prometheus:latest
docker pull grafana/grafana:latest

2、创建Prometheus的配置文件prometheus.yml：

global:
  scrape_interval: 15s
scrape_configs:
  job_name: 'prometheus'
    static_configs:
      targets: ['localhost:9090']

3、创建Grafana的配置文件grafana.ini：

[paths]
  data = /var/lib/grafana/data
  logs = /var/log/grafana
  plugins = /var/lib/grafana/plugins
[server]
  domain = localhost:3000
  http_address = localhost:3000
  root_url = %(protocol)s://%(domain)s/grafana/
  serve_from_sub_path = true
[database]
  type = postgres
  host = localhost:5432
  name = grafana_db
  user = grafana_user
  password = grafana_password
  role = grafana_role

启动Prometheus和Grafana容器并配置数据源

1、启动Prometheus容器：

docker run d name=prometheus p 9090:9090 v $PWD/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:latest

2、启动Grafana容器：

docker run d name=grafana p 3000:3000 v $PWD/grafana.ini:/etc/grafana/grafana.ini grafana/grafana:latest grafanaserver & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafanacli plugins install grafanapiechartpanel && killall HUP $(pgrep nf "grafanaserver") > /dev/null 2>&1 & sleep 15 && grafanacli admin resetadmin homepath=/usr/share/grafana skipbundle=true noprompt || true & sleep 15 && grafanacli plugins install promdashpanelapp && grafama
