Question

使用flocker时出现以下错误，是否有任何身体帮助？我正在使用CentOS7。

[root@agentNode ~]# docker run -v apples:/data --volume-driver flocker busybox sh -c "echo hello > /data/file.txt"
docker: Error response from daemon: create apples: create apples: Error looking up volume plugin flocker: plugin not found.
See '/usr/bin/docker-current run --help'.

[root@testnode7 ~]# docker run -ti -v volumename:/data --volume-driver=flocker busybox sh
docker: Error response from daemon: create volumename: create volumename: Error looking up volume plugin flocker: plugin not found.
See '/usr/bin/docker-current run --help'.

Answer 1

请运行docker -v并分享结果，我怀疑在最新的docker 1.12中发生了一些变化，也分享了你的flocker服务日志 cat /var/log/flocker/flocker-docker-plugin.log

Answer 2

我想我在这里遇到同样的问题。

检查是否安装了clusterhq-flocker-docker-plugin

[root@manager1 vagrant]# yum install clusterhq-flocker-docker-plugin
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.ventraip.net.au

Package clusterhq-flocker-docker-plugin-1.15.0-1.noarch already installed and latest version
Nothing to do

检查状态flocker-docker-plugin

[root@manager1 vagrant]# systemctl status flocker-docker-plugin

   Loaded: loaded (/usr/lib/systemd/system/flocker-docker-plugin.service; disabled; vendor preset: disabled)

启用并重启

好的，再试一次

[root@manager1 vagrant]# docker volume create --name persistent-vol-11 -d flocker
Error response from daemon: create persistent-vol-11: create persistent-vol-11: Error looking up volume plugin flocker: plugin not found

尝试使用带有docker run的插件

[root@manager1 vagrant]# docker run -v apples:/data --volume-driver flocker busybox sh -c "echo hello > /data/file.txt"
Unable to find image 'busybox:latest' locally
latest: Pulling from library/busybox

docker: Error response from daemon: create apples: create apples: Error looking up volume plugin flocker: plugin not found.

找不到flocker插件，来自守护进程的错误响应
