Executing multiple roles in succession

[Christopher Bachmeyer]

Hey all, 

I have two roles that are included in my site.yml and the goal is to execute the second role as soon as the first role completes.  I have added a task to generate a dynamic inventory in the first role that the second role can use.  I have a job Template in Ansible Tower and the first role executes cleanly but job Template completes without the second role executing.  

What am I missing?

- name: VMware-windows create role
  hosts: localhost           
  gather_facts: no
  roles:
  - vmware-windows

  vars_files:
    - ./roles/vmware-windows/vars/{{ vc_location }}.yml
    - ./roles/vmware-windows/vars/{{ network }}.yml

- name: Windows-post role
  hosts: windows
  gather_facts: no
  roles:
  - windows-post

Thanks!

You need to make sure you use proper indentation. Your roles list needs to be indented two spaces like your vars_files.

Is it possible also that your sourcing of those the vars_files from within your role is overwriting the value of "windows" such that there is no inventory for the second play? Why do you source those vars files? The vmware-windows role will do that automatically.

- name: VMware-windows create role
  hosts: localhost           
  gather_facts: no
  roles:
    - vmware-windows

### this vars_files should not be needed

  vars_files:
    - ./roles/vmware-windows/vars/{{ vc_location }}.yml
    - ./roles/vmware-windows/vars/{{ network }}.yml

- name: Windows-post role
  hosts: windows
  gather_facts: no
  roles:
    - windows-post

I presume that your vmware-windows role in the first play creates the host group called "windows" that you use as the inventory in your second play?

Hi, Walter, 

That is correct.  I am, the vmware-windows role is the first play and creates the host_group "windows" to be used as inventory in the second play. 

Right now, the second role is not indented but let me give that a go this morning.  I'm presuming to indent the entire block starting with the hyphen 

( - name: .... )? 

Regarding the vars_files, use import statements in the vars/main.yml of the first role?  I have multiple vars files under vars/ that are specific to the vcenters 

and vlans.  Using vars_files and variables in the Ansible Tower Survey gives the Admins a way to customize the builds to the environment (which works well!).

Thank you!

Does the vmware-windows role need the vars defined from the vars_files? If so then the role itself should include them inside it's task file(s). Move the vars_files inside tasks/main.yml. Anything the role does after that will get the value of those vars definitions.

The vmware-windows role will see the values of network and vc_location that come into the playbook executing the role. I presume they come in as extra_vars from command line or ansible tower.

Initially, I set up the Ansible Playbook outside of using a role, a plays/, vars/, group_vars/, and collections/ directories.  Yes, the network and vc_locations were being passed 

in as extra_vars in Anbible Tower via  a Survey.  

As things have grown, I recently converted that work over to an Ansible role.  The conversion worked well and things run accordingly through Ansible Tower.  The site.yml is what

is used including the vars_files sans the second role.  Now I am working on including the second role for post-processing needs of the deployed vms. 

Yes, the vmware-windows role needs variables defined for the vcenter, vlans, etc.  Currently, I have multiple ymls built out holding the vars such as:
     vlan1.yml, vlan2.yml, etc.

     vcenter1.yml, vcenter2.yml, etc.  

Doing it like this, I can have a prompt in the Survey for the Admins to customize the deployment.  I think I am following you, I can move those yml files over to tasks/ in the first role. 

I did indent the second role, having to remove the hyphen from "name."  In doing so, I received two warning:

"[WARNING]: While constructing a mapping from /tmp/bwrap_ ... /project/vmware-windows- role/provision.yml, line 3, column 3, found a duplicate dict key (name). Using last defined value only 

# Windows would be the inventory for the second role

[WARNING]: Could not match supplied host pattern, ignoring: windows

Thanks!

I have perused your reply but can't dig into it right at the moment. I will get back to it. Hopefully others also will chime in.

Hi, Walter, 

I have everything running as it should.  It was my mistake.  I didn't intend the full block in the initial email I sent this morning, only the block for the second role. 

The dynamic inventory is generated in the first role and passed to the second, and the end-to-end deployment of instances on VMware now works smoothly.  

I haven't had time to look at restructuring the vars yet but thanks for the input.  

Really appreciate it!

Thanks again!
