ssl - flocker-docker-plugin不起作用

我有2个centos 7.1节点，并且正在尝试在其上运行flocker。但是，在运行以下命令进行测试以查看flocker-docker-plugin是否有效时，我已经完全按照安装步骤进行了操作:
docker run -v apples:/data --volume-driver flocker busybox sh -c "echo hello > /data/file.txt"
我得到了错误:
Error response from daemon: Error looking up volume plugin flocker: Plugin not found
flocker-docker-plugin日志显示以下内容:

同时运行uft-flocker-volumes --control-service=foo.bar.net list-nodes会返回:

jonathan@ubuntu:~/Flocker/sc-test-cluster$ uft-flocker-volumes --control-service=foo.bar.com list-nodes
Unhandled Error

更新:

我尝试降级到docker 1.8.2并尝试重新运行该命令，但不起作用，出现同样的错误。

ls/etc/flocker的输出:

[root@sc-test2 jonathan]# ls /etc/flocker
agent.yml  cluster.crt  node.crt  node.key  plugin.crt  plugin.key

[root@sc-test1 jonathan]# ls /etc/flocker
agent.yml    control-service.crt  node.crt  plugin.crt
cluster.crt  control-service.key  node.key  plugin.key

更新:1/1/2016
我根据kubernetes docs http://kubernetes.io/v1.1/examples/flocker/设置了以下环境变量。

export FLOCKER_CONTROL_SERVICE_HOST=foo.bar.com
export FLOCKER_CONTROL_SERVICE_CA_FILE=/etc/flocker/cluster.crt
export FLOCKER_CONTROL_SERVICE_CLIENT_CERT_FILE=/etc/flocker/node.crt
export FLOCKER_CONTROL_SERVICE_CLIENT_KEY_FILE=/etc/flocker/node.key
export FLOCKER_CONTROL_SERVICE_PORT=4523

我在运行命令时遇到了另一个错误
jonathan@ubuntu:~/Flocker/sc-test-cluster$ uft-flocker-volumes --control-service=sc-test1.cloudapp.net list-nodes

wget: error getting response: Connection reset by peer
===========================================================================
Unable to establish network connectivity from inside a container.

If you see an error message above, that may give you a clue how to fix it.

If you run docker in a VM, restarting the VM often helps, especially if
you have changed network (and/or DNS servers) since starting the VM.

If you are using docker-machine (e.g. as part of docker toolbox), you can
run the following command (or similar) to do that:

    docker-machine restart default && eval $(docker-machine env default)

To ignore this check, and proceed anyway (e.g. if you know you are offline)
set IGNORE_NETWORK_CHECK=1
===========================================================================

因此，我设置了标志以查看会发生什么:jonathan@ubuntu:~/Flocker/sc-test-cluster$ export IGNORE_NETWORK_CHECK=1
和ba!同样的错误:(

jonathan@ubuntu:~/Flocker/sc-test-cluster$ uft-flocker-volumes --control-service=sc-test1.cloudapp.net list-nodes
Unhandled Error
Traceback (most recent call last):
Failure: twisted.web._newclient.ResponseNeverReceived: [<twisted.python.failure.Failure <class 'OpenSSL.SSL.Error'>>]

wget错误是有关可能发生的情况的有用线索吗？

最佳答案

这可能是由于agent.yml上的控制服务主机名配置不正确。确保它是控制服务器节点的主机，而不是代理节点本身。
