Escaping double curly braces in Ansible

Question

How to escape double curly braces in Ansible 1.9.2?

For instance, how can I escape double curly braces in the following shell command?

- name: Test 
         


        

Answer 1

I managed to work around my issue using a small script:

#!/usr/bin/env bash

docker inspect --format '{{ .NetworkSettings.IPAddress }}' "$1"

And the following Ansible play

- copy:
    src: files/get_docker_ip.sh
    dest: /usr/local/bin/get_docker_ip.sh
    owner: root
    group: root
    mode: 0770

- shell: "/usr/local/bin/get_docker_ip.sh {{ SWIFT_ACCOUNT_HOSTNAME }}"
  register: swift_account_info

Nevertheless, it's very surprising that Ansible doesn't allow escaping double curly braces!
