Getting the following error while trying to deploy a container with secrets on RHEL 7.1 host. Are Rancher Secrets supported in RHEL 7.1 version ?
Kernel Version - 3.10.0-693.5.2.el7.x86_64
Docker Version - docker-1.12.6-61.git85d7426.el7.x86_64
transitioningMessage": “Error response from daemon: linux mounts: Duplicate mount point ‘/run/secrets’”.
Take a look here, there is a workaround if you don’t need the entitlement/subscription info from RHEL in your containers:

OPTIONS=’–selinux-enabled --log-driver=journald --signature-verification=false enable-secrets=false’
