嗨，我已经进行了插件的测试，以在带有码头容器的Nutanix群集中进行集成（https://next.nutanix.com/karbon-karbon-kubernetes-orchesteration-30/nutanix-druge-dvp-dvp-dvp-dvp-dvp-docker-volume-volume-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-plug-IN-25371）和（https://next.nutanix.com/karbon-kubernetes-orchestration-30/docker-nutanix-container-volume-volume-plugume-plug-in-18726）。

在阅读docker卷插件文档时（https://portal.nutanix.com/page/documents/solutions/solutions/details?targetId=bp-2037-docker-containers-containers-on-ahv:bp-2037-2037-docker-containers-containers-containers-on-on-on-on-on-ahv），我没有注意到此类插件是否在Swarm模式（Docker Swarm Cluster）的Docker容器中使用。

我对Ubuntu 20.04进行了一些测试，形成了一个带有03个节点的Docker群集群，所有VM都安装了Nutanix宾客工具。使用.yml文件创建堆栈和服务的所有测试，如卷，对创建卷以及.yml文件中的命令进行了测试。我注意到这些卷是在群集和Nutanix群集中正常创建的，但是Docker容器没有启动，因为它们无法使用创建的卷。我注意到这些卷都是在群集群中的所有节点上创建的，即使我创建了每个节点01服务副本或在随机节点上的swarm cluster中只有01 replica的堆栈，但容器仍然无法使用该卷，因为它是因为它无法初始化。

当我遇到这个问题时，我找到了以下链接（https://myvirtualcloud.net/how-to-mimplement-docker-swarm-warm-with-postgresql-and-web-and-web-services-nutanix-on-nutanix-anix-acs-cersistent-persistent-卷/）报告在群集中使用DVP，指出您应该在Nutanix群集中检查卷组的配置中的选项选项“启用外部客户端访问”以及在启用此选项的测试中，即使是由于使用卷组的使用错误，因此Swarm Cluster中的容器也无法初始化。

当我阅读插件页面（https://hub.docker.com/plugins/nutanix-dvp-docker-volume-plug-in）时候，我还注意到在版本1.4中的版本部分中，提到了修复程序。涉及Docker Swarm的错误的问题，这使我认为DVP与Docker Swarm Cluster一起使用。

Hi Moises,<\/p>

Thank you for bringing this to our attention. The plugin should work with Docker Swarm (checked internally). I would suggest you open a case and please make sure to include the DVP logs as well as a an explanation to the steps you followed with the tests performed.<\/p>","className":"post__content__best_answer"}">

Hi, I have performed tests of the plugin for integration between Volume Groups in a Nutanix cluster with Dockers containers (https:\/\/next.nutanix.com\/karbon-kubernetes-orchestration-30\/nutanix-dvp-docker-volume-plug-in-25371) and (https:\/\/next.nutanix.com\/karbon-kubernetes-orchestration-30\/docker-nutanix-container-volume-plug-in-18726).<\/p>

\u00a0<\/p>

While reading the Docker Volume Plugin documentation at (https:\/\/portal.nutanix.com\/page\/documents\/solutions\/details?targetId=BP-2037-Docker-Containers-on-AHV:BP-2037-Docker-Containers-on-AHV), I did not notice if such a plugin works with Docker containers in swarm mode (Docker swarm cluster).<\/p>

\u00a0<\/p>

I performed some tests with Ubuntu 20.04, forming a Docker swarm cluster with 03 nodes, all VMs with Nutanix Guest Tools installed.\u00a0 All the tests using .yml files for the creation of stacks and services, as for the volumes the tests were made both with the command to create the volumes, as well as in the .yml files. I noticed that the volumes are created normally in the Swarm cluster as well as in the Nutanix cluster, but the Docker containers don't start because they can't use the volumes created. I noticed that the volumes are created on all nodes in the swarm cluster and even though I create stacks with 01 service replica per node or only 01 replica in the swarm cluster on a random node, the container still can't use the volume because it can't initialize.<\/p>

\u00a0<\/p>

\u00a0<\/p>

When I encountered this problem, I found the following link (https:\/\/myvirtualcloud.net\/how-to-implement-docker-swarm-with-postgresql-and-web-services-on-nutanix-acs-for-persistent-volumes\/) that reports the use of DVP in a swarm cluster, stating that you should check an option in the configuration of the volume group in the Nutanix cluster, however I did not find the option informed in the link, the closest I found was the option \"Enable External Client Access\" and in the tests I did with this option enabled, even so the containers in the swarm cluster cannot initialize due to the error in the use of the volume group.<\/p>

\u00a0<\/p>

When I read the plugin's page (https:\/\/hub.docker.com\/plugins\/nutanix-dvp-docker-volume-plug-in), I also noticed that in the Releases section, in version 1.4, it is mentioned the fix of a problem involving a bug with docker swarm, which led me to think that DVP works with Docker swarm cluster.<\/p>","quoteUsername":"Moises S F","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨，莫斯，

谢谢你让我们注意到这一点。该插件应与Docker Swarm（内部检查）一起使用。我建议您打开一个案例，请确保包括DVP日志以及对您执行的测试的步骤的解释。
