Flocker-docker-plugin not working

Question

I have 2 centos 7.1 nodes and am trying to run flocker. I followed the installation steps, however, when it comes to running the following command to check if flocker-docker-plugin works:

docker run -v apples:/data --volume-driver flocker busybox sh -c "echo hello > /data/file.txt"

I get an error message:

Error response from daemon: Error looking up volume plugin flocker: Plugin not found

The plugin-docker-plugin logs show the following:

Started Flocker Docker Plugin. Starting Flocker Docker Plugin... 

Also working uft-flocker-volumes --control-service=foo.bar.net list-nodes returns:

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

Update:

I tried downgrading to docker 1.8.2 and tried to restart the command, it didn't work, same error.

Output ls / etc / flocker:

 [ 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 

Update: 1/1/2016 I set the following environment variables according to the kubernetes docs http://kubernetes.io/v1.1/examples/flocker/ .

 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 

And I got another error when running the command

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 (eg 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 (eg if you know you are offline) set IGNORE_NETWORK_CHECK=1 =========================================================================== 

So, I set the flag to see what happens: jonathan@ubuntu :~/Flocker/sc-test-cluster$ export IGNORE_NETWORK_CHECK=1

And bam! Same error: (

 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'>>] 

Is wget error a useful hint about what might happen?

Answer 1

Error response from the daemon: volume plugin flex search error: plugin not found

This may be due to incorrect configuration of the management host name in agent.yml. Make sure that this is the host host server host, and not the host agent itself.
