Re: [ansible-project] Passing json in shell module in ansible

[Dick Visser]

Can you confirm that the exact same command (without single quotes around it) actually works from an interactive shell?

Hi All,

I need help with passing JSON in the shell module in ansible. 

Playbook - 

- hosts: localhost
  name: refresh asg
  connection: local
  gather_facts: True
  tasks:
  - name: refresh instances
    shell: 'aws autoscaling start-instance-refresh --region=us-east-1 --auto-scaling-group-name test_asg --preferences '{"InstanceWarmup": 400, "MinHealthyPercentage": 50}'

The error I'm getting is -

I would supply it as a yaml formatted variable to your task and then use the filter combo to_json|quote 

At least that's how I supply crazy complex dicts on aws cli commands and those work

Please let me know, how should I pass this in shell module within ansible?

Thanks

easiest way:

shell: !unsafe aws autoscaling start-instance-refresh

--auto-scaling-group-name Test_Iwo_nodes_Development_zone1
--preferences '{"InstanceWarmup": 400, "MinHealthyPercentage": 50}'

but breaking it down into variables is still a good idea, you only
need `!unsafe` on the 'dictionary looking' parts.
