How to Mount a Remote NFS Share Locally Using Ansible Playbook
Operating a server from your Localhost can often present unique challenges, especially when it comes to mounting files from a remote server. One common scenario is the need to mount a Network File System (NFS) share from a remote server directly onto your localhost while working with an Ansible playbook. If you've encountered difficulties in achieving this, you're not alone! In this guide, we'll guide you step-by-step through solving this problem, enabling you to mount an NFS share from a remote server with ease.
Understanding the Challenge
When utilizing Ansible to manage remote NFS shares, many users struggle with the limitations of playbooks configured to run against specific hosts. Typically, the goal is to use the playbook to access the necessary variables, such as the IP address of the NFS server, to execute the mount operation on the localhost where the playbook runs.
In your playbook, the confusion arises from needing to include the host variables from the nfs-server group without explicitly setting IP addresses in your settings file. Let’s break the solution down.
Solution Overview
To solve the issue, we will modify your current approach to ensure that the playbook targets the localhost while still accessing the required variables from the nfs-server group. Here’s how to do it:
Revisions in Your Playbook
Here’s the revised playbook based on your existing one:

Breakdown of Changes
Removed Redundant Delegation:
The delegate_to: localhost line is unnecessary when you are already targeting localhost in the playbook. Simplifying the task improves clarity.
Mounting Efficiently:
The crucial change is the mount task, where we set src to use hostvars[nfs_server0].ipaddress. This relies on a variable (nfs_server0) pulling the first IP address from the nfs-server inventory group.
Define the nfs_server0 Variable:
We define nfs_server0 as the first host in the nfs-server group. This makes it easier to access the IP address dynamically, without needing explicit entries in your settings.yaml file.
Getting It to Work
To implement these changes successfully, ensure that your inventory file includes the relevant entries for the NFS server. When you run this playbook, it will create the local directory and immediately proceed to mount the NFS share using the IP address of the nfs-server, thus avoiding manual configuration.
Conclusion
Mounting a remote NFS share on your localhost using Ansible can be streamlined by tweaking your playbook like we discussed. By dynamically accessing the IP address from your Ansible inventory, you eliminate the need for hardcoding, leading to improved maintainability and flexibility in your deployment scripts.
Feel free to experiment with your playbook further and observe how these strategies simplify your server management tasks. Happy automating with Ansible!
