grafana docker 安装使用

1.配置yum源

vim /etc/yum.repos.d/docker.repo 添加 [dockerrepo]name=Docker Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/7 enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg

2.使用yum命令安装docker

 yum install docker

3.启动测试docker

docker run hello-world
测试docker 安装是否有问题
docker version #查看版本

4.下载并运行grafana ,端口映射3000
但是这样启动的容器数据会因为重启而丢失所以官方推荐下面的方式来启动

docker run -d --name=grafana -p 3000:3000 grafana/grafana

另一种方式
创建持久化volume

docker run -d -v /var/lib/grafana --name grafana-storage busybox:latest

从volume获得数据启动

docker run \  -d \  -p 3000:3000 \  --name=grafana \  --volumes-from grafana-storage \  grafana/grafana

5.查看镜像

# docker imagesREPOSITORY                  TAG                 IMAGE ID            CREATED             SIZEdocker.io/grafana/grafana   latest              e4accc9ea909        6 days ago          302.8 MBdocker.io/hello-world       latest              05a3bd381fc2        8 days ago          1.84 kB

6.启动docker

 docker run -d -i -t e4accc9ea909 -p 3000:3000  /bin/bash

7.如果进入docker容器，比较常见的做法有

1. 使用docker attach

# docker psCONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES7d0a68fe4562        grafana/grafana     "/run.sh"           22 minutes ago      Up 22 minutes       0.0.0.0:3000->3000/tcp   grafanadocker attach 7d0a68fe4562

1. 使用SSH
2. 使用exec
   docker exec -it 7d0a68fe4562 /bin/bash
3. 使用nsenter
