docker化安装grafana

继续进行docker改造。

1. 找镜像、拉取镜像

[root@devlop ~]# docker search grafana

2. 启动镜像

docker run -d -p 3000:3000 --name=grafana -v /data/grafana:/var/lib/grafana grafana/grafana

3. 查看日志

[root@devlop ~]# docker logs -f grafana
GF_PATHS_DATA='/var/lib/grafana' is not writable.
You may have issues with file permissions, more information here: http://docs.grafana.org/installation/docker/#migration-from-a-previous-version-of-the-docker-container-to-5-1-or-later
mkdir: cannot create directory '/var/lib/grafana/plugins': Permission denied

发现报错，对'/var/lib/grafana/plugins'没有权限创建目录，那么就赋予权限：

chmod 777 /data/grafana

重启grafana

docker restart grafana

再次查看下日志，发现成功了
