Suppose i want to start a docker container and its parameters would differ based on a condition. Something like this:

docker\_container:  
name: typeA  
image: typeA  
volumes:

- a1:a1
- a2:a2  
when: type == A

docker\_container:  
name: typeB  
image: typeB  
volumes:

- b1:b1
- b2:b2  
privileged: yes  
when: type == B

I want to avoid writing and maintaining two similar tasks when i know always only one of them will execute. So is there a more elegant way to do this ? Like i define the differences in a dict var and only specify one docker\_container.

I tried this but this didn’t work. I was hoping that there is something similar possible

Avars:

name: typeA  
image: typeA  
volumes:

- a1:a1

Bvars:

name: typeB  
image: typeB  
volumes:

- b1:b1
- b2:b2  
privileged: yes

docker\_container: “{{ (type == A) | ternary ( Avars, Bvars) }}”
