Closed pomelio closed 5 years ago
I am not sure the reason is because the docker container can not be started on port 111 which is reserved on Mac.
When you change to another port such as -p 5111:111 the problem is the mount command doesn't have an option to specify the rpc new port 5111
You don't need to expose the RPC port, RPC isn't used with NFSv4. Its only there to overcome a bug with slow start up. Have you exposed 2049/tcp?
Actually, I had to set privileged mode on my container (16.04.1-Ubuntu) to be able to mount the nfs share form the inside of Kubernetes.
securityContext:
privileged: true
Adding the SYS_ADMIN capability to the container mounting the nfs share didn't suffice, I got permission denied.
Also, since I ran this on the "inside network" I didn't have to expose the 2049 port.
OK, good stuff, I didn't realise you were using K8s. Luckily that detail is already in the README. Thanks for reporting back.
Facing the same issue, Did we have a solution yet? I don't know why this been closed @sjiveson @caleno @pomelio .
I am running this as a stand alone container, facing the same problem and yes the privileged: true.
The problem is the client side can not mount the server. The error message is 'connection refused'
