You have this

  volumes:
  - '{{ dir1 }}:{{ dir1 }}'
  - '/tmp:/tmp'

The dashes indicates it's a list, and pretty sure if you check the 
documentation it says that volumes takes a list.
So create a variable with a list in it and provide that variable to volumes.

Define a variable
  vars:
    myvar:
    - '{{ dir1 }}:{{ dir1 }}'
    - '/tmp:/tmp'

and then use it

  volumes: '{{ myvar }}'
