While deploying new VM’s is easy with Ansible, I kept on struggling with setting the hostname. There is Ansible documentation to use vmware_vm_shell module to set the hostname. The following is stated on their help page.
- name: Change hostname of guest machine
vmware_vm_shell:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: no
datacenter: "{{ datacenter }}"
folder: "/{{datacenter}}/vm"
vm_id: "{{ vm_name }}"
vm_username: testUser
vm_password: SuperSecretPassword
vm_shell: "/usr/bin/hostnamectl"
vm_shell_args: "set-hostname new_hostname > /tmp/$$.txt 2>&1"
delegate_to: localhostWhatever I tried, I could not manage to get it working. It dit not error but just didn’t work.
After a couple of hours this is my workaround:
- name: Change hostname of guest machine
vmware_vm_shell:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: no
datacenter: "{{ datacenter }}"
folder: "/{{datacenter}}/vm"
vm_id: "{{ vm_name }}"
vm_username: testUser
vm_password: SuperSecretPassword
vm_shell: "/usr/bin/bash"
vm_shell_args: " -c \" {{item}} \" "
with_items:
- echo {{ vm_name }} > /etc/hostname
- hostname {{ vm_name }}
delegate_to: localhostNow it will set the hostname the same as the vm name.
It’s probably not perfect. Let me know if you have a better solution.
Have fun!
