在 RHEL 7 上将 Isilon NFS 用于 /var/lib/docker

在 RHEL 7 上将 Isilon NFS 用于 /var/lib/docker

RHEL：7.8 码头工人：1.13.1

该服务器由多个团队共享，我想让 docker 可用于那些无法/不会在笔记本电脑上安装它的人进行测试或沙箱。因为它是共享的，所以映像增长可能会显着，我想将 Isilon NFS 共享挂载为 /var/lib/docker。我使用“vfs”作为存储驱动程序使其工作，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"

我看到了尝试“chcon -Rt svirt_sandbox_file_t <mount_point>”的建议，但我得到了相同的“不支持操作”错误。

还有其他人让这个工作吗？我是不是走错了方向？

我通过卸载 RHEL docker 并从 docker.com 安装 docker 19.03.13 解决了这个问题。对于那些好奇的人：
