Have a script start running at a certain tag and run for every task that follows

[mgoldsb]

Hi.  I'm trying to implement an ad-hoc "restart" functionality in Ansible Tower similar to what is in the core Ansible CLI.  My idea is that, if a deployment fails, I can restart it at the tag that it failed at--however, if I specify this tag in the deployment, it will ONLY run that tag.  I am looking for a way such the deployment will *start* running at that specific tag and then continue to all of the subsequent tasks.

I can see one potential method whereby tags are added sequentially with each task.  For instance,

  - name: First task

            shell: echo "Kilroy Was Here" > /home/mgoldsb/Hello.txt

            failed_when: "{{ First }} == true"

            tags:

              - First_Task

                

          - name: Second task

            shell: echo "Kilroy Was Here" > /home/mgoldsb/World.txt

            failed_when: "{{ Second }} == true"

            tags:

              - First_Task

              - Second_Task

                

          - name: Third task

            #shell: echo "Kilroy Was Here" > /home/mgoldsb/Hows.txt

            shell: rm -f testthis.txt

            failed_when: "{{ Third }} == true"

            tags:
              - First_Task

              - Second_Task

              - Third_Task

                

          - name: Fourth task

            shell: echo "Kilroy Was Here" > /home/mgoldsb/It.txt

            failed_when: "{{ Fourth }} == true"

            tags:
              - First_Task

              - Second_Task

              - Third_Task

              - Fourth_Task

                

          - name: Fifth task

            shell: echo "Kilroy Was Here" > /home/mgoldsb/Going.txt

            failed_when: "{{ Fifth }} == true"

            tags:
              - First_Task

              - Second_Task

              - Third_Task

              - Fourth_Task

              - First_Task

However, I would much rather prefer only having a single tag for each task that uniquely refers to that task.

Can anyone offer any suggestions?

Thanks in advance.

Sounds like you might need --start-at-task see http://docs.ansible.com/ansible/playbooks_startnstep.html

It's been a while since I looked at the Tower ui but I think its an option on the each job from what I remember.

Hope this helps,

Jon

Yeah, I think I heard about --start-at-task, but unfortunately I'm not sure if there's any way to implement that in a Tower job template.  Here's a screenshot of what the job template UI looks like:
