Hi @all,
let me explain my scenario first, before I come to my question.
We run most of our linux servers as virtual machines in VMware vSphere
Clusters. I would like to use a playbook that takes a snapshot from a vm
befor it runs further tasks on the target node. In case of a broken system
after an upgrade I could revert the snapshot and I'm up and running again.
Here is a not working example playbook:
---
- hosts: localhost
connection: local
vars_prompt:
- name: "vc"
promt: "Enter Virtual Center Server FQDN"
private: no
- name: "vc_datacenter"
promt: "Enter Datacenter"
private: no
- name: "vc_user"
promt: "Enter username to connect to vCenter Server: Example:
[email protected]"
private: no
- name: "vc_passwd"
promt: "Enter your password"
privat: yes
vars:
nested_list:
- { folder: 'myfolder1', vm: 'vmname' }
- { folder: 'myfolder2', vm: 'vmname2' }
- { folder: 'myfolder1', vm: 'vmname3' }
tasks:
- name: snapshot operation
vmware_guest_snapshot:
hostname: "{{ vc }}"
username: "{{ vc_user }}"
password: "{{ vc_passwd }}"
datacenter: "{{ vc_datacenter }}"
folder: /mydatacenter/vm/"{{ item.folder }}"/
name: "{{ item.vm }}"
state: absent
snapshot_name: snap1
description: "Fuegen Sie hier Ihre Beschreibung ein"
validate_certs: false
delegate_to: localhost
with_item:
- "{{ nested_list }}"
- hosts: staging
tasks:
- name: run yum -y update
yum:
name: "*"
state: latest
The group 'staging' in the second play contains the hosts that should be
updated after a snapshot was taken. In the example above ansible would at
first try to create snapshots and at second update my nodes whether the
snapshot creation was successful or not. I have no idea how to create a
dependency from the second play to the first one.
Do you understand what I'm trying to accomplish? Do someone have an idea on
how to solve this?
Best regards,
Joerg
