how to get the exit status of the each task in ansible - ansible

Question

I have 3 task in my ansible yml file as below.
---
- name: Instance provisioning
local_action:
module: ec2
region: "{{ vpc_region }}"
key_name: "{{ ec2_keypair }}"
instance_type: "{{ instance_type }}"
image: "{{ ec2_image}}"
zone: "{{ public_az }}"
volumes:
- device_name: "{{ device }}"
volume_type: "{{ instance_volumetype }}"
volume_size: "{{ volume }}"
delete_on_termination: "{{ state }}"
instance_tags:
Name: "{{ instance_name }}_{{ release_name }}_APACHE"
environment: "{{ env_type }}"
vpc_subnet_id: "{{ public_id }}"
assign_public_ip: "{{ public_ip_assign }}"
group_id: "{{ sg_apache }},{{ sg_internal }}"
wait: "{{ wait_type }}"
register: ec2
- name: adding group to inventory file
lineinfile:
dest: "/etc/ansible/hosts"
regexp: "^\\[{{ release_name }}\\]"
line: "[{{ release_name }}]"
state: present
- name: adding apache ip to hosts
lineinfile:
dest: "/etc/ansible/hosts"
line: "{{ item.private_ip }} name=apache dns={{ item.public_dns_name }}
with_items: ec2.instances
Now i want to check the exit status of each task whether it is success or failure.
If any one of the task fails my other task should not execute.
Please advice how to write an ansible playbook

Answer 1

In your first task, you have register the output to ec2.
now use fail module to stop the play if the task fails.
Ex.
register: ec2
fail:
when: "ec2.rc == 1"
here rc is the return code of the command .. we are assuming 1 for fail and 0 for success.
use fail module after every task.
Let me know if it works for you ..

Answer 2

Register a variable in each task and then check it in the next task. See http://docs.ansible.com/ansible/playbooks_tests.html#task-results

Answer 3

This is already the default behavior in Ansible. If a task fails, the Playbook aborts and reports the failure. You don't need to build in any extra functionality around this.

Answer 4

Maybe playbook blocks and it's error handling is to help you?

- name: adding group to inventory file
lineinfile:
dest: "/etc/ansible/hosts"
regexp: "^\\[{{ release_name }}\\]"
line: "[{{ release_name }}]"
state: present
when: ec2 | changed
register: fileoutput
- name: adding apache ip to hosts
lineinfile:
dest: "/etc/ansible/hosts"
line: "{{ item.private_ip }} name=apache dns={{ item.public_dns_name }}
with_items: ec2.instances
when: fileoutput | changed
In your code register a variable in each and every Task if The Task has Changed to True, The Followed Task will execute otherwise it will skip that Task.
