Re: [ansible-project] Example for running a playbook using Python API

[Michael DeHaan]

Probably the best example of running a playbook via Python code is
actually /usr/bin/ansible-playbook itself, though it uses nearly all
of the flags.

https://github.com/ansible/ansible/blob/devel/bin/ansible-playbook

Anything referenced there either comes from command line flags or is
constructed further up in that file.

Hope that helps!

Hi Jazzed,

I used your example as a base for triggering ansible through a python script, however while the output suggest that the connection to the node is made and the playbook is running, individual steps on the various roles fail consistently in contrast to running the playbook using the ansible-playbook command line tool passing the same playbook.

The output suggests no clear reasons for this behavior.

Any ideas on that?

Thanks,
Dimitris

Thanks Jazzed,

Its working fine only if I have my host listed in /etc/ansible/hosts, but I want to pass my custom host file while running a playbook. Can you tell me how to do so?

[Mike Putnam]

Lavish,

You can override the default inventory file ( /etc/ansible/hosts ) with the shell environment variable ANSIBLE_HOSTS.

I use the EC2 dynamic inventory script ( http://docs.ansible.com/intro_dynamic_inventory.html#example-aws-ec2-external-inventory-script ) like this:

$ ANSIBLE_HOSTS=/path/to/ec2.py python myscript.py

How to run ansible-playbook on ansible2.0 or later version?

The ansible.playbook has been removed.

Hi all,

   I have a Playbook which is used to push template configuration to the router, It work fine if I run command ansible-playbook playbook_name.yml

But now I don't want call Playbook manually, I want to creat a file (such as pb.run) and then use it to call playbook.

How I can do it?

Please help me, thanks!

Hello Dao,

I did the same in ansible. 

• I created one pb.sh within the file i wrote below   
  

              ansible-playbook playbook1.yml

  

and saved.

• then i change the permission chmod +x pb.sh   and run those as   

           [root@localhost]# ./pb.sh 

i think it is useful to you also.
