服务器 docker 如何查看rabbitmq 版本号

要查看运行在 Docker 中的 RabbitMQ 版本号，可以使用以下命令：

docker exec <rabbitmq-container-name> rabbitmqctl status | grep RabbitMQ

其中，`<rabbitmq-container-name>` 是 RabbitMQ 容器的名称。

执行上述命令后，会输出 RabbitMQ 的相关信息，其中包括版本号，例如：

Status of node rabbit@<container-id> ...
[{pid,<pid>},
 {running_applications,[{rabbitmq_management,"RabbitMQ Management Console","3.6.9"},
                        {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.6.9"},
                        {rabbitmq_management_agent,"RabbitMQ Management Agent","3.6.9"},
                        {rabbit,"RabbitMQ","3.6.9"},
                        {mnesia,"MNESIA  CXC 138 12","4.14.3"},
                        {amqp_client,"RabbitMQ AMQP Client","3.6.9"},
                        {rabbit_common,[],"3.6.9"},
