在RHEL 7上为/var/lib/docker使用Isilon NFS

Question

RHEL: 7.8码头: 1.13.1

这个服务器是由几个团队共享的，我想让那些不能/不会在笔记本电脑上安装它的人可以使用对接器进行测试或沙箱。由于它是共享的，因此图像增长可能会非常显著，因此我希望将Isilon共享挂载为/var/lib/docker。我让它使用"vfs“作为存储驱动程序，但我认为这是导致以下错误的原因：

ERROR: for redis  Cannot create container for service redis: SELinux relabeling of <mount_point>/volumes/1185719ebf09771e9e9641f329c9c57f72792a942c283562f701ece914cca82a/_data is not allowed: "operation not supported"

我看到了一个尝试"chcon -Rt svirt_sandbox_file_t “的建议，但是我得到了同样的”不支持的操作“错误。

还有其他人成功了吗？我走错方向了吗？

我通过从docker.com卸载RHEL码头和安装码头19.03.13来解决这个问题。对于那些好奇的人：
