linux - Docker 卷不存储整个数据

Question

我在 Docker 中运行 activeMQ 并使用以下命令持久化数据。但是数据并没有完全保存在一个目录中

[root@kubernetes-4 activemq]# docker run -it --rm -v /MyPath:/data webcenter/activemq:5.14.3
2019-08-24 03:56:42,388 CRIT Supervisor running as root (no user in config file)
2019-08-24 03:56:42,388 WARN Included extra file "/etc/supervisor/conf.d/activemq.conf" during parsing

2019-08-24 03:56:44,969 INFO success: activemq entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)

我路径中的数据

cd /MyPath/
[root@kubernetes-4 MyPath]# ls
activemq
[root@kubernetes-4 MyPath]# cd activemq/
[root@kubernetes-4 activemq]# ls
[root@kubernetes-4 activemq]# 

容器中的数据

root@kubernetes-4 activemq]# docker exec -it 630a3fe743e2 bash
root@630a3fe743e2:/opt/activemq# ls

安装确切的 activemq direcotry你会看到一切正常。

docker run -dit --rm -v /MyPath:/data/activemq webcenter/activemq:5.14.3

第二，您没有挂载 /opt/activemq/data，因此无法在主机上访问。

出于日志目的，您可以挂载 v/var/log/activemq:/var/log/activemq
