By Luca Berton · Published 2024-01-01 · Category: installation
How to mount NFS and CIFS shares in Linux with Ansible mount module (ansible.posix.mount). Configure /etc/fstab entries, set mount options, and manage.
How to mount an NFS share in Linux with Ansible?
I'm going to show you a live Playbook with some simple Ansible code. I'm Luca Berton and welcome to today's episode of Ansible Pilot.See also: Ansible mount Module: Mount Filesystems, NFS, SMB/CIFS Shares (Guide)
Ansible mounts an NFS Share in Linux
• ansible.posix.mount • Control active and configured mount pointsToday we're talking about the Ansible module mount.
The full name is ansible.posix.mount, which means that is part of the collection of modules "ansible.posix" to interact with POSIX platforms.
The purpose of the module is to control active and configured mount points.
For Windows, use the community.windows.win_mapped_drive module instead.
Parameters
• path string - mount point (e.g. /mnt) • state string - mounted / unmounted / present / absent / remounted • src string - device or network volume • fstype string - ext4, xfs, iso9660, nfs, cifs, etc. • opts string- mount optionsThis module has many parameters to perform any task.
The only required are "path" and "state".
The parameter "path" specifies the path to the mount point (e.g. /mnt/).
The parameter "state" allows us to verify a specific state of the mount point. The options "mounted", "unmounted" and "remounted" change the device status. The "present" and "absent" options only change the /etc/fstab file.
The src parameter specifies the device or network volume for NFS or SMB/CIFS.
The fstype parameter specifies the filesystem type. For example ext4, XFS, iso9660, NFS, CIFS, etc.
The opts parameter allows us to specify some mount options, that vary for each filesystem type.
## Playbook
Let's jump in a real-life Ansible Playbook to mount an NFS share in Linux RedHat-like and Debian-like.
