docker Prometheus安装部署

Prometheus Server

Prometheus Server 本身也将以容器的方式运行在 host 192.168.56.103 上。

Exporter

Prometheus 有很多现成的 Exporter，完整列表请参考 https://prometheus.io/docs/instrumenting/exporters/

• 我们将使用：

  • Node Exporter，负责收集 host 硬件和操作系统数据。它将以容器方式运行在所有 host 上。

  • cAdvisor，负责收集容器数据。它将以容器方式运行在所有 host 上。

• 安装Node Exporter

docker run -d  \
-v "/proc:/host/proc" \
-v "/sys:/host/sys" \
-v "/:/rootfs" \
--net=host \
prom/node-exporter \
--path.procfs /host/proc \
--path.sysfs /host/sys \
--collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

ip + 端口 验证
使用--net = host 方便通信

• 各节点运行 cAdvisor，用来监控容器

docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--detach=true \
--name=cadvisor \
--net=host \
google/cadvisor:latest

ip + 端口 验证

• 安装 Prometheus Server

docker run -d -p 9090:9090 \
-v /root/prometheus.yml:/etc/prometheus/prometheus.yml \
--name prometheus \
--net=host \
prom/prometheus
