Here is a quick introduction to Kubernetes NFS mount options Our Server Support team is available to help you with your questions and concerns.

All About Kubernetes NFS mount options

Although NFS can be used as a storage backend for Kubernetes Persistent Volumes, we have to specify mount options for the NFS file system. Furthermore, these mount options spell out how the NFS file system is mounted as well as accessed by the Kubernetes cluster.

Additionally, the mount options are defined in the Persistent Volume definition via AML definition or via a StorageClass. Now, let’s take a quick look at some of the commonly used NFS mount options in Kubernetes:

• read-only:

  It specifies that the NFS file system has to be mounted in read-only mode.
• hard and soft:

  When the server is down or the connection breaks, these options control how the NFS client responds. Furthermore, If the server isn’t available, hard option will push the client to keep trying to connect, but the soft option will make the client return an error.
• read-only:

  The read-only mount of the NFS file system is specified by this option.
• vers:

  Vers option specifies which NFS protocol version to use.
• timeo and retrans:

  These options regulate the NFS file system’s timeout and retry policies.
• noac:

  The noac option disables attribute caching, thereby improving performance.
• sec:

  It mentions the security mode to use while accessing the NFS file system.
• addr:

  This option points out which NFS Server IP address to use.

According to our experts, we can customize how we access the NFS file system. Additionally, we can improve performance and reliability by defining the mount options in the Kubernetes Persistent Volume definition.
